cpputils is a C++ library I wrote. The result from that command is
aara...@aaragon-laptop:~/Lib/lib$ nm -g libcpputils.so | grep flip
00003c20 T _ZN8cpputils4flipEd
and if I filter that using c++filt:
aara...@aaragon-laptop:~/Lib/lib$ nm -g libcpputils.so | grep flip | c++filt
00003c20 T cpputils::flip(double)
Is there a way to make this macro work with C++ functions??? for the time
being, I thought that it might be a very good idea to create a function with
C linkage, so for example in my library I wrote:
extern "C" {
int cpputils_autotools() {
return 0;
}
}
so I can use that function in the test for autotools. This I guess is
something that should be done automatically by autotools when creating C++
libraries, so that people don't break their head agains the wall trying to
find out why the macros to test for libraries don't work.
