[cfe-dev] CompilerInstance as CPP compiler?

[Adam Smalin]

using this dummy source file

struct AA {
    int a, b, c;
    void ff(int z){ }
};
void funcAZ() {}
int main(){
    struct AA aa;
    int a=1;
}

I ran the code at the end of this email. there are no cmd line arguments and
the file is a.cpp.

When it runs my ASTConsumer i get the assert error

Unexpected diagnostic outside source file processing

however if i remove the ff function in AA, it runs fine. I assume the
problem is the compiler is running in c mode and i am using c++ source.
How do i tell it to compile in C++ mode?


    CompilerInstance compiler;

    compiler.createDiagnostics(argc, argv);
    CompilerInvocation::CreateFromArgs( compiler.getInvocation(),
    argv + 1, argv + argc, compiler.getDiagnostics() );

    compiler.setTarget( TargetInfo::CreateTargetInfo(
    compiler.getDiagnostics(), compiler.getTargetOpts() ) );

    compiler.createFileManager();
    compiler.createSourceManager(compiler.getFileManager());
    compiler.createPreprocessor();
    compiler.createASTContext();
    compiler.setASTConsumer( new PrintFunctionsConsumer);

    compiler.createSema(false, NULL);


    compiler.InitializeSourceManager( main_input_file );
    ParseAST( compiler.getPreprocessor(), &compiler.getASTConsumer(),
compiler.getASTContext() );
