Subject: Compiling 32bit executables on 64bit system with MUSL
I was able to do it before, although with some hassle and questions in the mailing list.
But today I tried again and it seems the old tricks does not work now.
What I am doing:
1. Compile and install MUSL for i386:
$ sudo ln -s /usr/bin/ar /usr/bin/i386-ar
$ sudo ln -s /usr/bin/ranlib /usr/bin/i386-ranlib
$ ./configure --host=i386 CC="gcc -m32"
$ make
$ sudo make install
2. edit the file /usr/local/musl/bin/musl-gcc (removing double quotes):
exec ${REALGCC:-gcc -m32} "$@" -specs "/usr/local/musl/lib/musl-gcc.specs"
3. Change the file /usr/local/musl/lib/musl-gcc.specs to the attached in this message.
As I said, this procedure happened to work before.
But now, when trying to compile some file, the compilation failed with linker error message.
Here is some simple test:
$cat ./hello.c
#include <stdio.h>
int main()
{
printf("Hello, World!");
return 0;
}
$musl-gcc -o hello ./hello.c
/usr/bin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/8.2.0/32/crtbegin.o: direct GOT relocation R_386_GOT32X against `_ITM_deregisterTMCloneTable' without base register can not be used when making a shared object
/usr/bin/ld: final link failed: nonrepresentable section on output
collect2: error: ld returned 1 exit status
Actually my C programming skills are very low, so I can't even understand what the linker is talking about.
The version of GCC is 8.2.0;
Any help will be appreciated!
