I've got it to work, by adding a 'main' function to my shared object code.
I don't understand why I need to do this though. I didn't think that
main' functions were required in shared objects, and when I compile
using the shell, it compiles ok without one. When I used the same
code on my old system, it worked without needing to add one, even in
the exec function executions.
Could this be a bug in GCC? The version I'm using currently is 4.3.3.
Alternatively, is there another option I should add when using exec
functions to call GCC to prevent the need for adding 'main' functions?
If gcc works as you expect when invoked from the shell, then I don't
think it can be a bug in gcc. I think it must be a bug in the way that
you are invoking it from your program. Or maybe you have a shell alias
or something, who knows.
There is nothing magic about exec. The shell uses exec also. gcc does
not behave differently when invoked via exec or via the shell--it can't.
