I am attempting to cross-compile on AIX with the xlc/xlC compilers.
The code compiles successfully when it uses the default settings on another machine. The code actually successfully compiles with the cross-compilation, but the problem comes from the linker. This is the command which links the objects together:
$(CHILD_OS)/usr/vacpp/bin/xlC -q32 -qnolib -brtl -o $(EXECUTABLE) $(OBJECT_FILES)
-L$(CHILD_OS)/usr/lib
-L$(CHILD_OS)/usr/vacpp/lib/profiled
-L$(CHILD_OS)/usr/vacpp/lib
-L$(CHILD_OS)/usr/vac/lib
-L$(CHILD_OS)/usr/lib
-lc -lC -lnsl -lpthread
-F$(CHILD_OS)$(CUSTOM_CONFIG_FILE_LOCATION)
When I attempt to link the code, I get several Undefined symbols: .setsockopt(int,int,int,const void*,unsigned long), .socket(int,int,int), .connect(int,const sockaddr*,unsigned long), etc.
I have discovered that the symbols missing are from the standard c library, libc.a. When I looked up the symbols with nm for the libc.a that is being picked up, the symbols do indeed exist. I am guessing that there might be a problem with the C++ being unable to read the C objects, but I am truly shooting in the dark.
