Subject: | dlopen(0, RTLD_LAZY) doesn't work? |
Hi, I've read the mailing list archives and searched google trying to figure out how to get the following program to work. All you have to do is save it to a file (foo.c), compile (gcc foo.c), and run - I always get "dlsym() failed." Note, I have tried many variations of extern and _declspec as well as looking for "_foo" in addition to "foo" ("nm a.exe | grep foo" returned "0040104c T _foo"... Here is the code - help would be greatly appreciated - thanks! #include <stdio.h> #include <dlfcn.h> #include <windows.h> extern __declspec(dllexport) void foo(void) { printf("hello\n"); } int main(int argc, char *argv[]) { void* dl = NULL; void* func = NULL; dl = dlopen(0 , RTLD_LAZY); if (dl == NULL) { printf("dlopen() failed\n"); exit(0); } func = dlsym(dl, "foo"); if (func == NULL) { printf("dlsym() failed\n"); exit(0); } printf("do something meaningful\n"); dlclose(dl); return 0; } -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
