I am having a strange problem with a DLL built with Cygwin (gcc 3.2 200290927 and ld 2.13.90 20021118).
I downloaded a package from the Net and built it as a DLL. Then, I wrote to programs, one which linked implicitly with the DLL, and one which linked explicitly (dlopen()ed the DLL, and then dlsym()ed the symbols). No problem with the implicit link. But, with the explicit link, weird things happen: dlopen() succeeds, but most dlsym() fail. The strangest thing is, some dlsym() actually succeed (they return the correct pointer) but most don't (they return NULL)! I tried to build the same DLL with the Micro$oft tools (cl.exe and link.exe), and both programs, unmodified, work! That is, all dlsym() succeed. It seems a bug in Cygwin's ld, the dynamic linker. If you request me, I can send the test programs by e-mail. __________________________________________________________________ Tiscali ADSL.
