Most programs in the repository are regularly and automatically compiled
|
|
by the autobuild server, compiled binaries are available at
|
|
http://builds.kolibrios.org. The autobuild server uses the build system Tup,
|
|
data for it are located in files named Tupfile.lua over the repository.

|
|
|
|
Q1. I want to build one program and I don't want to know anything about Tup.
|
|
A1. Fine. You will need a corresponding compiler, obviously.
|
|
|
|
* For a FASM program, get FASM at http://flatassembler.net/download.php.
|
|
To compile, find the main .asm file of the program and run
|
|
path/to/fasm <input.asm>
|
|
The compiler will automatically select the name for output, using
|
|
base name of input and extension based on file format. Though, you can
|
|
give also output name explicitly, as the second argument.
|
|
|
|
If the compiler produces an error "file not found" regarding 'lang.inc',
|
|
the program can be compiled using different languages of interface.
|
|
Create a file 'lang.inc' in the same folder as <input.asm> like follows:
|
|
lang fix en
|
|
Here the last word selects the language. Valid languages are
|
|
en, ru, et, it, sp. Not all programs provide all translations,
|
|
en should always be available, ru is the most frequent after en.
|
|
|
|
* For a NASM program, get NASM at http://www.nasm.us/.
|
|
To compile, find the main .asm file of the program and run
|
|
path/to/nasm -f bin -o <output> <input.asm>
|
|
Multi-language is rarely supported in this category, but you could still
|
|
see sometimes an error "file not found" regarding 'lang_nasm.inc'. If so,
|
|
create a file 'lang_nasm.inc' in the same folder as <input.asm> like follows:
|
|
%define lang 'en'
|
|
Read the entry about fasm for description of valid languages.
|
|
|
|
* For a c-- program, try to avoid compiling it and instead rewrite the code
|
|
in a normal language like assembler or C. If you absolutely need
|
|
to compile, note that the compiler has been abandoned long ago, so
|
|
don't look for an official site. It is possible to find the compiler
|
|
somewhere on http://board.kolibrios.org, but be prepared to several tries
|
|
because there are several slightly different compiler versions, not all of
|
|
which are able to build all programs.
|
|
There is no Linux version, but Windows version runs fine under Wine.
|
|
|
|
* For a GCC program, get the toolchain at
|
|
http://ftp.kolibrios.org/users/Serge/new/Toolchain/.
|
|
|
|
Under Windows, you need the package with "msys" in name and MinGW;
|
|
after installing MinGW, unpack the package to
|
|
\MinGW\msys\1.0\home\autobuild\tools\win32, the package assumes
|
|
exactly this path. Run MinGW shell.
|
|
|
|
Under Linux, you need the package with "linux" in name
|
|
and runtime library cloog; e.g. for Debian-based distributives
|
|
use apt-get install libcloog-isl4. Unpack the package to
|
|
/home/autobuild/tools/win32, the package assumes exactly this path.
|
|
|
|
In both MinGW and Linux, make sure that the command
|
|
/home/autobuild/tools/win32/bin/kos32-gcc
|
|
invokes the compiler.
|
|
|
|
If the program uses libraries, you will also need to either compile
|
|
them separately or download SDK, if they are included to SDK.
|
|
Compiling is ultimately a sequence of calls to kos32-gcc and kos32-ld,
|
|
but filling exact parameters can be tricky, so maybe you want to
|
|
use Tup - proceed to Q2/A2 - or Make, if a maintainer has provided
|
|
Makefile.
|
|
|
|
* For a MSVC program, get the compiler as a part of Visual Studio,
|
|
Express Edition is fine, or as a part of Windows SDK.
|
|
For obvious reasons, there is no Linux version, but the compiler runs fine
|
|
under Wine.
|
|
|
|
If the program uses libraries, you will also need to either compile
|
|
them separately or download SDK, if they are included to SDK.
|
|
Compiling is ultimately a sequence of calls to cl.exe and link.exe,
|
|
but filling exact parameters can be tricky, so maybe you want to
|
|
use Tup - proceed to Q2/A2 - or Make, if a maintainer has provided
|
|
Makefile.
|
|
|
|
* For any language, if the program is KolibriOS binary, the compiled binary
|
|
can optionally be compiled with kpack. Windows version of kpack
|
|
can be downloaded at http://diamond.kolibrios.org/prg/kpack.exe,
|
|
Linux version can be compiled from sources at
|
|
(repository)/programs/other/kpack/linux.
|
|
|
|
* The kernel can optionally be compiled with kerpack.
|
|
Linux version can be compiled from sources at
|
|
(repository)/programs/other/kpack/kerpack_linux.
|
|
There is no Windows version.
|
|
|
|
Q2. I want to build one program using Tup.
|
|
A2. You will still need the corresponding compiler as described in Q1/A1.
|
|
You will also need Tup, get it at http://gittup.org/tup/index.html.
|
|
Make sure that the corresponding compiler is somewhere in PATH
|
|
and can be invoked without explicit path. For Linux, note that
|
|
all programs are invoked without extension, like
|
|
fasm
|
|
or
|
|
kos32-gcc
|
|
with one exception: MSVC linker is invoked as link.exe to avoid conflict
|
|
with link from coreutils. Under Linux, c--, cl, link.exe should be scripts
|
|
invoking Wine with the corresponding binary. The interaction tup+wine
|
|
does not work by default; ultimately, invoking scripts should be like:
|
|
c--: WINEDEBUG=-all LD_PRELOAD=/path/to/nosetsid.so /path/to/wine /path/to/C--.exe $*
|
|
cl: WINEDEBUG=-all LD_PRELOAD=/path/to/nosetsid.so /path/to/wine /path/to/cl.exe -I/path/to/cl/include $*
|
|
link.exe: WINEDEBUG=-all LD_PRELOAD=/path/to/nosetsid.so /path/to/wine /path/to/link.exe $*
|
|
where nosetsid.so is compiled as a 32-bit shared library
|
|
from C file with one line "int setsid() { return -1; }".
|
|
|
|
If the program does not use any libraries, run
|
|
tup init
|
|
in the directory with the program. Then,
|
|
tup
|
|
without arguments will build the program with default settings.
|
|
Subsequent runs will not do anything unless any file that was used
|
|
during the compilation - not necessarily the main file - is changed;
|
|
after that, the program will be recompiled.
|
|
By default, tup will not track files outside the directory with "tup init";
|
|
if tracking files in program directory is not sufficient for you,
|
|
consider adding updater.full_deps=1 to tup config - see tup manual
|
|
for details, for Linux it requires setting tup as suid root - or extending
|
|
tup data to the entire repository as described in Q6/A6.
|
|
|
|
Settings can be configured using the file tup.config. Look to
|
|
tup.config.template in the repository root for complete list;
|
|
for most programs, only CONFIG_LANG and CONFIG_KPACK_CMD have effect.
|
|
|
|
If the program uses libraries or helper files for gcc/msvc and you don't
|
|
want to build everything at once like Q6/A6, set
|
|
CONFIG_HELPERDIR=.
|
|
in tup.config, copy programs/use_gcc.lua or programs/use_msvc.lua
|
|
and helpers for used libraries, if any, to the directory of the program.
|
|
use_gcc.lua and use_msvc.lua do not require additional configuration;
|
|
in helpers for used libraries, set path to library in the first line.
|
|
Since copied helpers are local files not for the repository, you may use
|
|
absolute pathes specific for your machine.
|
|
This was designed so that no repository files need to be modified:
|
|
Tupfile.lua for the program is able to use either local helpers when
|
|
CONFIG_HELPERDIR is set, or repository helpers when the entire repository
|
|
is built.
|
|
You will also need compiled libraries. If they are included in SDK, use them.
|
|
Otherwise, compile them using the same process. Note that for a library,
|
|
"tup init" needs to be called in the library directory with include/ and lib/,
|
|
even if Tupfile.lua is present only in src/; libraries will be put in lib/.
|
|
|
|
Q3. I want to add a program to the autobuild.
|
|
A3. Select a program from repository which uses same language and libraries.
|
|
Copy Tupfile.lua from that program to your program.
|
|
Change names of source and binary files accordingly.
|
|
If external files are referenced, correct relative pathes accordingly:
|
|
e.g. when programs/develop/libraries/menuetlibc_example/Tupfile.lua
|
|
references ../../../use_menuetlibc.lua, it resolves to
|
|
programs/use_menuetlibc.lua, if your program is built by
|
|
programs/other/super_program/Tupfile.lua, the path should be
|
|
../../use_menuetlibc.lua. Commit.
|
|
|
|
After that, the program will be built regularly.
|
|
To include the binary in kolibri.img or kolibri.iso, add it to one of
|
|
lists in data/Tupfile.lua. Select the section corresponding to the used
|
|
language so that people who build images without your compiler would still
|
|
be able to do so.
|
|
|
|
Q4. I want to build the entire system.
|
|
A4. Why? Even the person who has configured the autobuild server does not build
|
|
everything on her computer.
|
|
|
|
If you want to create your own image of the system, it is much simpler to
|
|
start from existing one and modify it, building only what is necessary.
|
|
Look for Q7/A7 for details of that approach.
|
|
If you don't know how to modify an image, don't expect that the build
|
|
system will magically do it for you. The build system uses mtools for
|
|
image manipulation; if you have configured mtools, you can just use them
|
|
directly. There are also other ways of image manipulation, which would
|
|
be closed for you once you decide to become attached to the build system.
|
|
|
|
If you want to verify or debug your changes in Q3/A3, it is normally
|
|
sufficient to build just what you have changed as in Q2/A2.
|
|
To be extra sure, you can build from the repository root as in Q6/A6
|
|
limiting to your compiler and FASM for some helper tasks;
|
|
any possible differences between this mode and actions of the autobuild
|
|
server are due to environment issues, like Windows vs Linux,
|
|
and would not be resolved anyway.
|
|
|
|
If you just want it, note that the full build requires all compilers
|
|
listed in Q1/A1 and Linux. MinGW and Cygwin will not help you.
|
|
|
|
Q5. I'm sure that I want to build the entire system.
|
|
The autobuild server does this, after all.
|
|
A5. The autobuild server has one concrete configuration with 64-bit Linux.
|
|
The developers are slightly interested in compiling programs in different
|
|
systems, but nobody needs portability of actions that only one server
|
|
does anyway.
|
|
|
|
So, don't expect support from developers. Though, here goes the instruction
|
|
in interest of completeness.
|
|
|
|
* Configure all compilers as described in Q2/A2.
|
|
* Configure kpack and kerpack as described in Q2/A2.
|
|
They are optional for Q2/A2, but required here,
|
|
the image just could not contain all programs in unpacked form.
|
|
* Configure mtools, so that mformat, mmd and mcopy are somewhere in PATH.
|
|
* Configure mkisofs.
|
|
* For full duplication of the autobuild server configure build variants:
|
|
create directories build-eng, build-rus, ... in the root of repository for
|
|
every subdirectory in data/ except data/common. Create files
|
|
build-eng/tup.config, build-rus/tup.config, ... with
|
|
CONFIG_BUILD_TYPE=eng, rus, ... correspondingly. This will switch
|
|
to out-of-tree builds for every variant. If one build type is sufficient
|
|
for you, you may skip this step.
|
|
* Run
|
|
tup init
|
|
in the root of repository.
|
|
* Run
|
|
tup
|
|
anywhere inside repository.
|
|
* If everything went good, there should be files kolibri.img and kolibri.iso
|
|
in every build-* directory. When you want to update,
|
|
rerun tup without arguments.
|
|
|
|
Q6. I don't want to keep a zoo of compilers and tools required for Q5,
|
|
but I still want to build as many programs as possible with what I have.
|
|
A6.
|
|
* Configure all compilers you want to use as described in Q2/A2.
|
|
* Create tup.config in the root of repository. Disable all compilers you
|
|
don't want to use there; comments in tup.config.template should help you.
|
|
* Optionally, configure kpack and kerpack as described in Q2/A2.
|
|
* Run
|
|
tup init
|
|
in the root of repository.
|
|
* Run
|
|
tup
|
|
anywhere inside repository.
|
|
|
|
Q7. I have modified the source code of the kernel, one driver or one program
|
|
and want to test changes.
|
|
A7. First, you need to build the corresponding binary as described in Q1/A1 or
|
|
Q2/A2.
|
|
To test a program, it is sufficient to put it to some place accessible
|
|
to the working KolibriOS and just run it from there. Drivers are loaded
|
|
from the folder /rd/1/drivers/, which is initialized from kolibri.img,
|
|
so testing a driver requires either copying the compiled binary to
|
|
/rd/1/drivers manually between KolibriOS startup and loading driver or
|
|
inserting the driver to the image kolibri.img outside of KolibriOS.
|
|
Testing the kernel or an auto-loading driver requires modifying the image.
|
|
|
|
There are several possible approaches for writing to kolibri.img.
|
|
* From inside KolibriOS, write to /rd/1 and then save the ramdisk image.
|
|
* On Linux, there is a package named "mtools",
|
|
https://www.gnu.org/software/mtools/ . It can be available in the
|
|
repository of your Linux distribution or it can be compiled manually.
|
|
Compiling mtools for Windows is not impossible, but not supported either.
|
|
Using mtools:
|
|
mdir -i kolibri.img [<dir>]
|
|
lists contents of the given directory of the image or the root directory
|
|
if <dir> is omitted;
|
|
mcopy -moi kolibri.img <file> ::<imgfile>
|
|
inserts the file <file> to the image using the name <imgfile>; with
|
|
reverse order of the arguments, it extracts the corresponding file.
|
|
* On Linux with root privileges, the standard mount command can be used:
|
|
mount -t vfat -o loop kolibri.img <dir>
|
|
maps contents of kolibri.img under the directory <dir>, which must exist,
|
|
hiding whatever was in <dir>. When done, use
|
|
umount <dir>
|
|
* On Windows with administrator privileges, the driver ImDisk
|
|
http://www.ltr-data.se/opencode.html/#ImDisk can be used:
|
|
imdisk -a -m A: -t file -f kolibri.img
|
|
maps contents of kolibri.img to the virtual disk A:. When done, use
|
|
imdisk -d -m A:
|
