RE: OpenSSL compilation errors in Windows

[Nagalakshmi V J <nagalakshmi.j@xxxxxxxxxx>]

Hi Michael,

 

OpenSSL code is compiling without any issues. When it is used from our product code and while compiling using C++ compiler, the issue is seen.

 

We also don’t use the ‘warning as errors’ and warning level 3 we are using currently.

 

Thanks and regards,

Nagalakshmi

We compile using Visual Studio. We don't use 'warnings as errors' and selected a warning level that minimized warnings. The 'make test' runs cleanly.

Hi,

I am using openssl 1.1.c from our product code. 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.

 

 

 

Thanks and regards,

Nagalakshmi
