Creating a cross-compilation environment for RISC OS NetSurf
--------------------------------------------------------------------------------
| Note: If you want to do a native RISC OS build, on a RISC OS computer,
| consult the BUILDING-RISC_OS file.
These instructions assume that you're starting from ~.
They also assume that you've got GCCSDK's prerequisites installed.
Building the toolchain
========================
Run the following commands.
$ svn co svn://svn.riscos.info/gccsdk/trunk/ gccsdk
$ cd gccsdk/gcc4
$ ./build-world
$ export GCCSDK_INSTALL_CROSSBIN=/home/riscos/cross/bin
$ export GCCSDK_INSTALL_ENV=/home/riscos/env
Creating the environment
==========================
A. Autobuilder packages
-------------------------
$ cd ../
$ mkdir build-ab
$ cat > build-ab/build-setvars
GCCSDK_INSTALL_CROSSBIN=/home/riscos/cross/bin
GCCSDK_INSTALL_ENV=/home/riscos/env
RO_SHAREDLIBS=no
AB_ELFBUILD=yes
$ cd build-ab
$ ../autobuilder/build zlib1g
$ ../autobuilder/build c-ares
$ ../autobuilder/build libxml2
$ ../autobuilder/build libssl0.9.8
$ ../autobuilder/build libcurl3
$ ../autobuilder/build libjpeg62
$ ../autobuilder/build liblcms1
$ ../autobuilder/build libpng12-0
$ ../autobuilder/build libmng1
$ ../autobuilder/build oslib
B. NetSurf libraries
----------------------
Install the NetSirf project's libraries as follows.
$ cd ~
$ svn co svn://svn.netsurf-browser.org/trunk netsurf
$ (cd netsurf/libnsbmp ; make TARGET=riscos install)
$ (cd netsurf/libnsgif ; make TARGET=riscos install)
$ (cd netsurf/libsvgtiny ; make TARGET=riscos install)
$ (cd netsurf/rufl ; make install)
$ (cd netsurf/pencil ; make install)
$ (cd netsurf/libharu ; make TARGET=riscos PREFIX=$GCCSDK_INSTALL_ENV)
$ cd netsurf/libparserutils
$ cat >Makefile.config.override
CFLAGS += -DWITH_ICONV_FILTER
$ make TARGET=riscos install
$ cd ~
$ (cd netsurf/hubbub ; make TARGET=riscos install)
$ (cd netsurf/libwapcaplet ; make TARGET=riscos install)
$ (cd netsurf/libcss ; make TARGET=riscos install)
C. Ancilliary tools
---------------------
$ svn co svn://svn.riscos.info/ccres/trunk ccres
$ (cd ccres ; make install)
$ (cd netsurf/tools/makerun ; make install)
Compiling NetSurf
===================
Finally, to cross-compile NetSurf for RISC OS, do the following.
$ cd netsurf/netsurf
$ make TARGET=riscos
