Hey @aichamb,

Seems like your compiler failed to compile your sources to object files and what we see here is the linker failing to find those object files for linking them together into the csim.exe.

Check the logs for indications why the compiler failed, here are some potential reasons ...

• Missing access permissions
• Not enough disk space
• Weird network mounts with time differences
• Problem with the compiler or libraries

Hope that helps,

Herbert

i think the problem from the c++ compiler how can i fix it.

Hey @aichamb,

It seems like you are including a C++ header in a C file.

Double check that your source file is configured as C++.

Best,

Herbert

Hello @ hpoetzl,

i fix the majority of errors by installing VS 2017 ,now i have only 2 errors

Hey @aichamb,

Still looks like you are including C++ header files (directly or indirectly) from a non C++ source file.\

Best,

Herbert
