In the FWIW column.... Please don't mangle names by forcing C++ namespaces. Some us call OpenSSL from Python (and other dynamic languages) and depend on the C naming convention. Adding a "OSSL_" prefix is fine; mangling creates huge problems.

Yes, in this case I'd expect that error. You need to include stdlib.h outside of any namespace before you include openssl/foo.h. My advice would be to stick a bunch of include statements for all the standard headers used by any openssl/*.h into a single .h file, and then include that at the top of myproject.h and any other C++ header file that includes an OpenSSL header. So: - Create openssl_c_hdrs.h which has: #include <stdlib.h> #include <stdio.h> #include <string.h> ... - Change myproject.h to have: #include "openssl_c_hdrs.h" namespace myproject { #include <openssl/foo.h> } Again, I can't say for sure that will work, because I haven't tested it. But it ought to work around this particular issue. The standard headers included by openssl_c_hdrs.h will preempt their inclusion within the namespace by the OpenSSL headers. Of course, for C++ code you normally wouldn't include the C standard headers; you'd use their C++ versions (<cstdlib>, etc). But this sort of thing is a special case. -- Michael Wojcik Technology Specialist, Micro Focus This message has been scanned for malware by Websense. www.websense.com ???H???7??m???? )z{,???RǫJ?i??Lj)b????)z{,?? ??)z{,????h??^t???Ƨj??????&??^??%??
