I have the full Apple SDK on my desktop system and so I would like to build Nagios/NRPE and all the various bits and bobs on my machine and then distribute the binaries to the mini’s. The problem is that the mini’s are 32bit and my desktop is 64bit. Can anyone tell me how to compile 32bit on a 64bit machine. </blockquote> Generally, adding "-m32" to your CFLAGS (and probably CPPFLAGS) environment variables will force 32-bit compilation, assuming you're using gcc. </body> </html>
