GCC cross compiler for x86_64-elf
Hi,
I am building GCC cross compiler for x86_64-elf
for that a have followed steps,
1. mkdir build-gmp build-mpfr
2. cd build-gmp
3. ../gmp-4.2/configure --prefix=/usr/local
4. make all install
5. make check
6.cd ../build-mpfr
7. ../mpfr-2.3.2/configure --prefix=/usr/local/
8. make all install
9. export LD_LIBRARY_PATH= /usr/local/lib
----------------------------------------------------------------------
10. export PREFIX=/usr/cross
11. export TARGET=x86_64-elf
12. cd /usr/src
13. mkdir build-binutils build-gcc
14. cd ../build-binutils
15. ../binutils-2.18/configure --target=$TARGET --prefix=$PREFIX --disable-nls
16. make all
17. make install
18. export PATH=$PATH:$PREFIX/bin
19. cd ../build-gcc
../gcc-4.3.2/configure --target=$TARGET --prefix=$PREFIX --disable-nls
--enable-languages=c,c++ --without-headers --with-gmp=/usr/local --with-mpfr=/usr/local
20. make all-gcc install-gcc
------Porting new library------
21. cd build-newlib/
22. ../newlib-1.17.0/configure --prefix=$PREFIX --target=$TARGET
23. make all install
-------------Rebuild GCC with headers......
using the --with-headers option to tell GCC where to find the headers of new C library.
24. ../gcc-4.3.2/configure --target=$TARGET --prefix=$PREFIX --disable-nls
--enable-languages=c,c++ --with-headers=/usr/cross/x86_64-elf/include --with-gmp=
/usr/local --with-mpfr=/usr/local
25. make all-gcc
26. make install-gcc
It is successfuly installed. But when i am compiling simple helloworld program it is giving error as
[root@vm-centos12 build-gcc]#x86_64-elf-gcc hello.c
/usr/cross/lib/gcc/x86_64-elf/4.3.2/../../../../x86_64-elf/bin/ld: crt0.o: No such file: No such file or directory
collect2: ld returned 1 exit status
I have searched for crt0.o file but this file is not present in gcc installed folder.
Please tell me where is the problem and steps that i followed are correct or not.
I am very much thankful to you.
Regards
Mandar.

python2.7-config
PYTHON-CONFIG(1) General Commands Manual PYTHON-CONFIG(1) NAME
python-config - output build options for python C/C++ extensions or embedding SYNOPSIS
python-config [ --prefix ] [ --exec-prefix ] [ --includes ] [ --libs ] [ --cflags ] [ --ldflags ] [ --help ] DESCRIPTION
python-config helps compiling and linking programs, which embed the Python interpreter, or extension modules that can be loaded dynamically (at run time) into the interpreter. OPTIONS
--cflags print the C compiler flags. --ldflags print the flags that should be passed to the linker. --includes similar to --cflags but only with -I options (path to python header files). --libs similar to --ldflags but only with -l options (used libraries). --prefix prints the prefix (base directory) under which python can be found. --exec-prefix print the prefix used for executable program directories (such as bin, sbin, etc). --help print the usage message. EXAMPLES
To build the singe-file c program prog against the python library, use gcc $(python-config --cflags --ldflags) progr.cpp -o progr.cpp The same in a makefile: CFLAGS+=$(shell python-config --cflags) LDFLAGS+=$(shell python-config --ldflags) all: progr To build a dynamically loadable python module, use gcc $(python-config --cflags --ldflags) -shared -fPIC progr.cpp -o progr.so SEE ALSO
