Hi, Some programs like smlnj, which is SML by New Jersey, support only 32-bit binaries. On Linux distros, I can use gcc multilib support. How do I do that in OpenBSD?
I installed gcc-4.7.2 package and used that to compile to see whether I can get it to generate a 32-bit binary. $ egcc -m32 hello.c -o hello /usr/bin/ld: warning: i386 architecture of input file `/tmp//ccMULgjf.o' is incompatible with i386:x86-64 output So, it seems to use the system linker. To confirm that: $ egcc -v Using built-in specs. COLLECT_GCC=egcc COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/x86_64-unknown-openbsd5.2/4.7.2/lto-wrapper Target: x86_64-unknown-openbsd5.2 Configured with: /usr/obj/gcc-4.7.2/gcc-4.7.2/configure --verbose --program-transform-name='s,^,e,' --disable-nls --disable-checking --with-system-zlib --disable-libmudflap --disable-libgomp --disable-tls --with-as=/usr/bin/as --with-ld=/usr/bin/ld --with-gnu-ld --with-gnu-as --enable-threads=posix --enable-wchar_t --with-gmp=/usr/local --disable-libstdcxx-pch --enable-languages=c,c++,fortran,objc,ada --enable-cpp --enable-shared --prefix=/usr/local --sysconfdir=/etc --mandir=/usr/local/man --infodir=/usr/local/info --localstatedir=/var --disable-silent-rules Thread model: posix gcc version 4.7.2 (GCC) Do I have to build gcc-4.7.2 from ports with multilib support? For simple programs, export CFLAGS="-m32" export LDFLAGS="-m32" works. But, if I want to compile something like sml-nj, then the make fails. Thanks Salil
