Set CONFIG_MULTIARCHDIR for cross compilers.
Chances a cross-compiler will find a working crt*.o
in /usr/lib are more or less 0.
This commit breaks x86 / x86_64 compilres for linux. A solution for the crt*.o
must be discussed.
must be:
# ./x86_64-tcc -vv
tcc version 0.9.26 (x86-64, Linux)
install: /usr/local/lib/tcc
crt:
/usr/lib64
libraries:
/usr/lib64
/lib64
/usr/local/lib64
include:
/usr/local/include
/usr/include
/usr/local/lib/tcc/include
elfinterp:
/lib64/ld-linux-x86-64.so.2
and with MULTIARCH we have:
# ./x86_64-tcc -vv
tcc version 0.9.26 (x86-64 Linux)
install: /usr/local/lib/tcc/
crt:
/usr/lib/x86_64-linux-gnu ???????????????????
libraries:
/usr/lib/x86_64-linux-gnu
/usr/lib ???????????????????
/lib/x86_64-linux-gnu
/lib ???????????????????
/usr/local/lib/x86_64-linux-gnu
/usr/local/lib ???????????????????
include:
/usr/local/include/x86_64-linux-gnu
/usr/local/include
/usr/include/x86_64-linux-gnu
/usr/include
/usr/local/lib/tcc/include
elfinterp:
/lib64/ld-linux-x86-64.so.2
And CONFIG_MULTIARCHDIR don't handle C67.
On Linux x86 we have:
# ./c67-tcc -vv
tcc version 0.9.26 (C67, Linux)
install: /usr/local/lib/tcc
crt:
/usr/lib
libraries:
/usr/lib
/lib
/usr/local/lib
include:
/usr/local/include
/usr/include
/usr/local/lib/tcc/include
elfinterp:
/lib/ld-linux.so.2
Tiny C Compiler - C Scripting Everywhere - The Smallest ANSI C compiler ----------------------------------------------------------------------- Features: -------- - SMALL! You can compile and execute C code everywhere, for example on rescue disks. - FAST! tcc generates optimized x86 code. No byte code overhead. Compile, assemble and link about 7 times faster than 'gcc -O0'. - UNLIMITED! Any C dynamic library can be used directly. TCC is heading torward full ISOC99 compliance. TCC can of course compile itself. - SAFE! tcc includes an optional memory and bound checker. Bound checked code can be mixed freely with standard code. - Compile and execute C source directly. No linking or assembly necessary. Full C preprocessor included. - C script supported : just add '#!/usr/local/bin/tcc -run' at the first line of your C source, and execute it directly from the command line. Documentation: ------------- 1) Installation on a i386/x86_64/arm Linux/OSX/FreeBSD host (for Windows read tcc-win32.txt) Note: For OSX and FreeBSD, gmake should be used instead of make. ./configure make make test make install Alternatively, out-of-tree builds are supported: you may use different directories to hold build objects, kept separate from your source tree: mkdir _build cd _build ../configure make make test make install Texi2html must be installed to compile the doc. By default, tcc is installed in /usr/local/bin. ./configure --help shows configuration options. 2) Introduction We assume here that you know ANSI C. Look at the example ex1.c to know what the programs look like. The include file <tcclib.h> can be used if you want a small basic libc include support (especially useful for floppy disks). Of course, you can also use standard headers, although they are slower to compile. You can begin your C script with '#!/usr/local/bin/tcc -run' on the first line and set its execute bits (chmod a+x your_script). Then, you can launch the C code as a shell or perl script :-) The command line arguments are put in 'argc' and 'argv' of the main functions, as in ANSI C. 3) Examples ex1.c: simplest example (hello world). Can also be launched directly as a script: './ex1.c'. ex2.c: more complicated example: find a number with the four operations given a list of numbers (benchmark). ex3.c: compute fibonacci numbers (benchmark). ex4.c: more complicated: X11 program. Very complicated test in fact because standard headers are being used ! As for ex1.c, can also be launched directly as a script: './ex4.c'. ex5.c: 'hello world' with standard glibc headers. tcc.c: TCC can of course compile itself. Used to check the code generator. tcctest.c: auto test for TCC which tests many subtle possible bugs. Used when doing 'make test'. 4) Full Documentation Please read tcc-doc.html to have all the features of TCC. Additional information is available for the Windows port in tcc-win32.txt.
