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 remove the include to openssl/hmac.h I can compile successfully.
I am wondering if there is a patch that I need to install to remove
these lines from the header file?

is the compile error on the header file (asn1.h) or at the call ?
copy and paste the error include any necessary code.

I have the following code but I still get the compile errors described
below. There are no other openssl includes or function calls other than
what is shown below.
extern "C" {
#include <openssl/hmac.h>
}

I am trying to call the HMAC function (openssl 0.9.8e) within my C++
code. 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.
Justin
