multilib problem when building m68k buildtools on Linux 32-bit

[luroh]

IRC user OmniMancer found the problem why the m68k buildtools fail to build on 32-bit Linux systems; 'configure' tries to create some 64-bit libraries. This can be worked around by installing, in my case, the libc6-dev-amd64 meta package, but that's not a very elegant solution.

Google tells me there might be a --disable-multilib option available that we possibly could pass to GCC somehow.

Still here in 44022:

checking if gcc  -m64 supports -fno-rtti -fno-exceptions... no
checking for gcc  -m64 option to produce PIC... -fPIC -DPIC
checking if gcc  -m64 PIC flag -fPIC -DPIC works... yes
checking if gcc  -m64 static flag -static works... no
checking if gcc  -m64 supports -c -o file.o... yes
checking if gcc  -m64 supports -c -o file.o... (cached) yes
checking whether the gcc  -m64 linker (ld) supports shared libraries... yes
checking dynamic linker characteristics... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES.
make[1]: *** [configure-zlib] Error 1

hrev43954 mentions some multilib problem with x86_64.

Fixed in hrev44031. This adds a dependency on zlib on the host for GCC4 only.

Thanks korli. I have added zlib1g-dev to the build guide here: ​https://www.haiku-os.org/guides/building/pre-reqs Please have a look to see if it makes sense.

Good job, one less !

Replying to luroh:

zlib1g-dev is the name of the zlib dev package for some Linux distro, it might not apply to BSD or OS/X for instance. Maybe keep it generic in the section "Requirements for compiling the build tools", "zlib development" and be more specific sections.

Thanks for the clarifications, I'll update the guide accordingly.
