Dependencies

• Mono download address

Note that I have copied the Mono x64 runtime library to the \dependency\mono directory, so only the C++ code can be compiled without installing Mono. I have compiled the C# code in advance to generate MainTest.dll, so you still need to install Mono in order to recompile the C# code.

Compiler Guide

C++ compile to generate exe needs to be configured as follows.

• Compile include: \dependency\mono\include\mono-2.0`

• Linker lib path: \dependency\mono\lib

• Linker lib: mono-2.0-sgen.lib

C# compile to generate dll (On Windows)

• After installing Mono, add the \Mono\bin` folder to the PATH of the environment variable

• 64-bit installation will be completed in: C:\Program Files\Mono\bin. 32-bit in C:\Program Files (x86)\Mono\bin

• In cmd go to the directory where the Program.cs file is stored

• mcs Program.cs -t:library
