Build with QNX Momentix Toolchain

[Daniel Graupner]

Hello

we'd like to run our tests directly on a QNX target. They use a
modified gcc.

I tried to compile it without GTEST_OD_* define and -
DGTEST_USE_OWN_TR1_TUPLE=1.

Now there are some errors I do not know how to deal with:

Any suggestions?

Hi Daniel,

The POSIX standard -- to which Google Test is designed -- dictates that functions read, write, close, chdir, rmdir, and isatty be declared in the header <unistd.h>. If your toolchain declares them in another header, patch gtest-port.h to #include it.

HTH,

Vlad

Thanks
Daniel

[adding back the list]

Ok, first of all, gtest doesn`t support QNX as POSIX-system. Please,
add __QNX__ variable for POSIX lists in internal/gtest-port.h

gtest did away with the list of POSIX systems in revision 448.

 

Also, with QCC (QNX default toolchain) pthreads detection doesnt`work.
Manually adding #include <pthread.h> helps me get gtest works !

Update gtest to a later revision and you only need to add -DGTEST_HAS_PTHREAD=1 to your compiler options to have pthread.h included. If you use the configure script, that can be achieved by giving it the --with-pthreads=yes option.

 

Finally, QNX QCC doesn`t support tr1 tuple, which can be handled by -
DGTEST_HAS_OWN_TR1_TUPLE.
