Hi friends,
I've got a extrange problem compiling (linking, actually) under cygwin,
maybe you can help me. The same procedure works prefectly on Linux, so I
think I am probably not making some thing that is somehow needed on cygwin.
I've got a set of .c files to be compiled and merger in a library. So
far, so good. But, when I compile the test, it complains about missing
functions. As you can see in the trace below, the function _testBP_1 is
_not_ in the lib, but I am not using it!. Why is gcc (ld, actually)
trying to find _testBP_1() when I was using testBP_1().
As said, exactly the same code, the same Makefile and the same
procedure works on Linux.
I've also tried to use "libao-g.a" in the command line, instead of "-L.
-lao-g", but it fails as well.
Any idea?
