The problem is this: I have a small program that uses the dlopen(), dlsym() etc functions to access functions in a Dynamic Library. I can get this test program to run under SunOs and Linux but not under FreeBSD. The closest I get is mprotect failed for "./libadd.so" : Invalid argument: ./libadd.so when I run the program and yet the very same test works perfectly on the the other systems (albeit with different compiler options) Can someone please correct the two makefile rules below or otherwise explain how to build these things under FreeBSD. Thanks in advance!
