Re: How to run the cpp(preprocessor) g++ tests?

[Andres Tiraboschi <andres dot tiraboschi at tallertechnologies dot com>]

I'm running the test from top-level build directory.
Trying with those different commands I always have the same error:
Illegal Argument "g++.dg=cpp/*".

Is RUNTESTFLAGS=g++.dg='cpp/*' ok?

Thanks,
AndrÃs.
