I'm writing a program that uses the libapt-pkg library. In my configure.in I wanted to check to see if libapt-pkg.so was installed and gve a warning if it isn't. The way to do this I'm told is to use the AC_CHECK_LIBS macro giving it the name of the library and a function in that library. autoconf writes a little program to see if it can link to that function. If it can it proves the library exists.
Sounds quite simple. Trouble is it wouldn't work. After 15 minutes of total befuddlement it dawned on me why: C++ mangles function names. I used objdump -T to get the mangled name, plugged that in and sure enough it worked. I hope this helps anyone who has faced the problem themselves. I have a question too, is there anyway to use the unmangled name? AFAIK, mangling isn't portable and unportability kind of defeats the whole purpose of using autoconf don't you think? -- Jaldhar H.
