That's interesting. I have no problems with Version: 4.9.1-4ubuntu3+14.1

but on another (debian) system with Version: 4.2.1.dfsg-2 I see the same thing you're seeing.

Must have been added fairly recently.

See also: http://sourceforge.net/p/mingw/bugs/1912/

We could add a check for strnlen, I suppose, and if not present include one of the definitions given in that thread? But maybe not worth the hassle, since newer versions of mingw seem to work.

nwellnhof commented 9 years ago

Seems related to feature test macros. We probably have to compile with _POSIX_C_SOURCE in addition to _GNU_SOURCE. Can you check whether the following patch helps?

Same error with patch.

richard-lyman commented 9 years ago

I ran and have since re-run with 'make clean' and it still shows the same error.

Did you maybe compile from previous checkout without running make clean? If not, can you post the whole output of make VERBOSE=1?

nwellnhof commented 9 years ago

OK, then we should simply avoid strnlen. I'll probably have a fix ready by tomorrow.

Result of make VERBOSE=1 mingw after a make clean:

mkdir -p build-mingw; \
    cd build-mingw; \
    cmake .. -DCMAKE_TOOLCHAIN_FILE=../toolchain-mingw32.cmake -DCMAKE_INSTALL_PREFIX=windows ;\
    make && make install
