Could someone please provide guidance with this topic. You can
help by filling in the blanks. I have searched the mailing lists
man pages and the net at large without getting a satisfactory
understanding.
Consider the following scenario.
I need to compile a program consisting of two source files.
main.c --> contains --> int main(int argc, char **argv)
misc.c --> contains --> int funcA(arg1, arg2, ... )
main() does not know in advance that it has to invoke funcA.
It uses dlopen()/dlsym() to obtain references and invoke funcA.
The two source files will be linked into a single executable.
I am using GCC running on FreeBSD 3.1-RELEASE.
Q1 : What flags are required to compile the individual source files?
Q2 : What flags are required to link the object files into the
single executable?
Q3 : Is there anything else I should be wary of?
Thanking you in advance.
