[cfe-dev] getting at the compiler error messages array?

[Paul Griffiths]

ok, i have changed from:



TextDiagnosticPrinter *DiagClient =
		new TextDiagnosticPrinter(llvm::errs(), DiagnosticOptions());

	Diagnostic Diags(DiagClient);
	Driver TheDriver(Path.str(), llvm::sys::getHostTriple(),
		"a.out", /*IsProduction=*/false, /*CXXIsProduction=*/false,
		Diags);


to:

TextDiagnosticBuffer *DiagClient =
		new TextDiagnosticBuffer();

	Diagnostic Diags(DiagClient);

	

	Driver TheDriver(Path.str(), llvm::sys::getHostTriple(),
		"a.out", /*IsProduction=*/false, /*CXXIsProduction=*/false,
		Diags);

but when i add the following code, I get get no errors reported even
though I have added some errors to my c code.


if (!Clang.ExecuteAction(*Act))
	{
		TextDiagnosticBuffer::const_iterator 	itTextDiagnosticBuffer;

		{
                        vector<std::String> vWarnings;
			int iTotalWarnings = 0;
			for (itTextDiagnosticBuffer = DiagClient->warn_begin();
itTextDiagnosticBuffer != DiagClient->warn_end();
++itTextDiagnosticBuffer)
			{
				vWarnings.push_back(itTextDiagnosticBuffer->second.data());
				iTotalWarnings++;
			}

			char cErrorText[255];
			sprintf (cErrorText, "Total %d warnings!", iTotalWarnings);
		}

		{
                        vector<std::String> vErrors;
			int iTotalErrors = 0;
			for (itTextDiagnosticBuffer = DiagClient->err_begin();
itTextDiagnosticBuffer != DiagClient->err_end();
++itTextDiagnosticBuffer)
			{
				vErrors.push_back(itTextDiagnosticBuffer->second.data());
				iTotalErrors++;
			}

			char cErrorText[255];
			sprintf (cErrorText, "Total %d errors!", iTotalErrors);
		}

	}

what am i doing wrong?
