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.
You cannot run a 64-bit application on 32-bit hardware. If you did, in fact, install the compiler on the 64-bit host, you must also install the "run time" libraries. check the documentation for that. The "run time" libraries must be compiled for 64-bit hardware, so either they are cross-compiled, or compiled statically on the target host.
Yes sir,
I am not executing 64-bit application. I want to compile only.
Now the proble is of C Runtime library, To resolve this i have installed newlib library, So i got header files for new compiler but not getting library files ie libgcc.a libc.so etc.
I am cross compiling the library by giving target as x86_64-elf.
[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
See if the crt0.o file is anywhere in
/usr/cross/lib/gcc/x86_64-elf/
using find.
find /usr/cross/lib/gcc/x86_64-elf -type f -name crt0.o -ls
Yes i tried this but this file is not found.
So i searched for this error and somewhere i got idea to copy crt0.o from target machine(64-bit) in /usr/cross/x86_64-elf/lib.
Then this "crt0.o file not found" is resolved but getting another errors for "*.o" files,
means it is not getting C library files.
After installation in my system only libc.a, libm.a, libg.a, libnosys.a files are created in /usr/cross/x86_64-elf/lib directory.
I am not getting whether i missed any option for library files while configuring and installing newlib / GCC.(steps i followed are in previous post)
Please tell me what i have to do for this problem.
I do not have specific experience with this, but as I said in my first post, in order to make any cross compiler work, you must also install all cross-platform libraries, header files, etc. This includes the "stub object" .o files that gcc is currently requiring. Again, look at the documentation carefully to determine what steps are required for installing the support libraries and object files.
However you compile it, the linker still needs to find the static or dynamic objects which will be used to ultimately execute the program. This means you have to have all 64-bit libraries installed upon which the program depends. Apparently, then, before you cross-compile a program, you must install all supporting libraries, or cross compile them. Installing would be much easier.
