error: "__GXX_EXPERIMENTAL_CXX0X__" is not defined [-Werror=undef]

[dev123]

I have build (./confgure && make) gtest 1.7 on:

Linux ubuntu 3.11.0-15-generic #23-Ubuntu SMP Mon Dec 9 18:17:04 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

and:

gcc (Ubuntu/Linaro 4.8.1-10ubuntu9) 4.8.1

but when I build my tests I get:

I have found this:

https://netbeans.org/bugzilla/show_bug.cgi?id=214186

which seems related but it does not really provide a solution. I have not found anything here:

https://code.google.com/p/googletest/wiki/V1_7_FAQ

either.

Thanks for the report.

It's specified behavior for the preprocessor that X expands to 0 if X is not defined, so gtest is actually not invalid here, but it's understandable to consider supporting all the strict flags people want to use, especially in test builds.

Your immediate needs can be met by removing -Wundef while we work on it.

 FYI the build also fails when throwing errors on the following warnings:

-Wctor-dtor-privacy

-Wabi
