first: the extern "C" around the hmac.h is not necessary. get rid of it. second: the errors are make no sense at all; these header files you are referencing are Unix/Linux files are they not ? meaning they are not files built in a Windows environment (i hope not) third: a rebuild of openssl is something that I might try next. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Phillips, Justin - ACD Sent: Wednesday, September 12, 2007 9:07 AM To: openssl-users@openssl.org Subject: RE: C++ compatability
The error is on the header file asn1.h. I have commented out the call to HMAC so the only related code is the include which at this point looks like. extern "C" { #include <openssl/hmac.h> } Here is the error...

When I include <openssl/hmac.h> I get compilation errors on the asn1.h file at lines 905, 915, 920, 933, 938, and 985 all saying "invalid conversion from 'void (*)() to 'void*'. This makes sense because the libraries are compiled with gcc but I am compiling my software with g++ and in C++ this type of casting is not allowed. So my question is how do you use openssl in C++ when the include files use C specific syntax such as this? Thank you in advance for the help.
