Hi Matthias,
Yes that's right. The error message is ..\..\OpenSSL\openssl-1.1.1c\crypto\../ssl/packet_locl.h(429) : error C2440: '=' : cannot convert from 'void *' to 'unsigned char *' Conversion from 'void*' to pointer to non-'void' requires an explicit cast Sorry, it was missed by mistake. So how can we avoid this? In our code, We included “ssl_locl.h” which in turn includes packet_locl.h. Any way to avoid this kind of error?

Line 429 is an assignment from 'void *' to 'unsigned char*', not to 'unsigned char'. Such an assignment is allowed in C (and the type is implicitly converted), but not in C++. Is it possible, that you are including this header in a module compiled with a C++ compiler? Note that this is an internal header file and not meant to be included by third party software.

While compiling the code, I am getting the errors which can be suppressed as warnings using -fpermissive flag in Linux (gcc/g++). In windows, I am getting the same compilation errors in visual studio (2005). Would like to know the alternative of -fpermissive flag that can be used in visual studio to suppress the errors. I tried adding the flags such as '/fpermissive' , '/Ze' in module properties->C/C++->command Line->Additional options. But it did not resolve the problem. Getting the errors like below. ssl/packet_locl.h(429) : error C2440: '=' : cannot convert from 'void *' to 'unsigned char 'Conversion from 'void' to pointer to non-'void' requires an explicit cast Since it is giving error in Openssl code, we cannot make any code changes there. Has anyone faced this kind of issue? Please let me know how to resolve this issue.
