网页2013年11月27日 — There is no problems in running 32 bits executables on 64 bit OS (as long as 32 bit dynamic libraries are present and found). -m32 is there to compile 32 bits objects on a compiler configured to compile 64 bits objects by default. As long as the OS supports both 32bit and 64bit programs (hint: not all do, such as OpenBSD) on a 64bit OS, then ...
Force gcc to compile 32 bit programs on 64 bit platform
网页2010年8月17日 — In most cases you can provide your CFLAGS, CXXFLAGS and LDFLAGS variables to the configure script. You also might need to add --build and --host to the configure script so you end up with something like. ./configure CFLAGS=-m32 CXXFLAGS=-m32 LDFLAGS=-m32 --build=x86_64-pc-linux-gnu --host=i686-pc-linux-gnu. If compilation fails this probably ...
