Google Test 1.6 with Cygwin: 'fileno' was not declared in this scope

[Bill]

Error message when building a simple test on Factorial() function in Eclipse CDT:

Eclipse CDT 8.1 running gcc 4.7.3 on Cygwin 1.7.22
gTest 1.6 succesfully built including demo tests, with cmake 2.8.9 on Cygwin 1.7.22
I've linked the built lib with full path, E:\lib\gtest-1.6.0\Cygwin\libgtest.a

The following command option was added manually, got same error without it.
-DGTEST_OS_CYGWIN=1

Seems the errors have nothing to do with my code. Any advice please?

Thank you,

Even I'm getting the same error in cygwin..! If I don't specific the C++ standard as "-std=C++0x", I don't get any compilation error. Also, another observation is it compiles successfully in my RHEL6 OS, so I think it's got something to do with cygwin..! but not sure what it is..

Try Setting the c++ standard to -std=gnu++0x rather than -std=c++0x. It worked for me. Your compile statement would be something like :

g++ -std=gnu++0x -DGTEST_OS_CYGWIN=1 -I"E:\source\gtest-1.6.0\include" -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/challenge.d" -MT"src/challenge.d" -o "src/challenge.o"
