I'm trying to run purify on CentOS on an Intel Pentium 4/630 processor. Purify does not like the 64bit code. Is there some way to compile and run programs so that they are only using the 32 bit model?
I tried gcc -m32 but then the system libraries come up missing.
Purify engine: Error: Couldn't open the file crt1.o
Purify engine: Error: Couldn't open the file crti.o
Purify engine: Error: Couldn't resolve library directive: -ltcl8.4, (couldn't find library libtcl8.4.so or libtcl8.4.a).
Purify engine: Error: Couldn't resolve library directive: -ldl, (couldn't find library libdl.so or libdl.a).

Yup, -m32 is the correct option. What you are missing are 32-bit development packages. Check for and install (and I mean install, not update, you want to have both i386 and x86_64 development packages) i386 versions of glibc-devel and libgcc. Depending on what you are trying to compile, you might need other i386 development packages. As you'll notice, x86_64 distribution contains both i386 and x86_64 versions of almost all libraries, however only i386 runtime gets installed by default, you must add development parts for i386 manually. For example, to compile C++ stuff, you'll need i386 libstdc++-devel. Esiest way to find out what you need to install is to locate 64-bit version of library that you probably already have installed, and then do for example rpm -qf /usr/lib64/libwhatever.so and see what package it belongs to (probably whatever-devel), and install i386 version of it.
