Error in compiling CppSharp on Linux

[nubby109]

I am using ubuntu 14.04 . I am new to open source community. I am trying to compile CppSharp but i am getting the error'/usr/include/wchar.h(39,11): fatal: 'stdarg.h' file not found CppSharp has encountered an error while parsing code.' again and again. Could someone please tell me its a error from my side or some bug.
This is what happens in the terminal

This is a bug in our pre-built CI packages, I will take a look at properly fixing later.

For now, you can look at the workaround we have put into place here:

CppSharp/src/Generator.Tests/GeneratorTest.cs

Line 53 in bbe7c1c

if (Environment.GetEnvironmentVariable("TRAVIS_OS_NAME") == "linux")

Comment the if so its not just restricted to Travis CI, and make sure you edit the include path to match the one in your system and it should work.

            //if (Environment.GetEnvironmentVariable("TRAVIS_OS_NAME") == "linux")
                options.addSystemIncludeDirs("/usr/lib/gcc/x86_64-linux-gnu/(your_gcc_version)/include");
