Howdy all, I'm trying to build a dll using OpenSSL (of course). In the installation notes for the w32 platform there was a special note: ... One final comment about compiling applications linked to the OpenSSL library. If you don't use the multithreaded DLL runtime library (/MD option) your program will almost certainly crash: see the original SSLeay description below for more details. ... Well, I've done this and it still doesn't work at all. When I call for the instruction PEM_write_PKCS7(fOut,p7); it does certainly crash. It worked when compiling in a prompt line command but not building a DLL. That is, when I run the function in DOS it goes fine but the same code built in a DLL doesn't. The problem seems to be in the BIO library... Does anyone know the answer? ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
