Crosscompiling

[G öran Boström]

I need to compile a program for a system using kernel 2.0.38. This kernel uses libc.so.5.
Unfortunately I have no development system using this library. The system I use is RH 5.2 using libc.so.6!

I tried to install a libc5 package on my /usr/local/libc5 directory. When I compile this happens:

gcc -o test test.c -I/usr/local/libc5/include \-I /usr/local/libc5/include/pcap \
-L/usr/local/libc5/lib -lpcap
/usr/lib/crt1.o(.text+0xe): undefined reference to `__libc_init_first'
/usr/lib/crt1.o(.text+0x18): undefined reference to `_environ'

Something went wrong!?? I must have missed something since the compiler yells for /usr/lib and not inte /usr/local/libc5/lib ...

I made some test using -nostartfiles and explicitly link the crt1.o file from the libc5 tree, but those executables won't run on my target system!!?

What have I missed?
