Hi,
Just to inform CMake users on Mac OS X that problem is solved by
using CTEST_USE_LAUNCHERS option.
As a reminder, problem is that some warnings generated by
different clang processes during parallel compilation get mixed
together, become unreadable, and are therefore processed as errors
by ctest.
With 'CTEST_USE_LAUNCHERS' option, stdout and stderr outputs of
parallel clang processes are handled differently and do not get
mixed together anymore.
More details about this option are available in this page at item
2. :
http://www.kitware.fr/blog/home/post/11
To activate CTEST_USE_LAUNCHERS in you ctest script, following
lines are needed :
set(CTEST_USE_LAUNCHERS 1)
...
ctest_configure(BUILD "${CTEST_BINARY_DIRECTORY}"
OPTIONS "-DCTEST_USE_LAUNCHERS=${CTEST_USE_LAUNCHERS}"
... )
A last point : a side effect of this option I have observed
is that warnings and errors are counted differently. Number of
compilation units yielding errors and warnings are counted, and
not individual errors and warning messages.
If someone knowns a method to use CTEST_USE_LAUNCHERS option with
individual counting of error and warning messages, I am
interested.
Hope this helps,
Kind regards
Ananda

Hi,
We have the same problem here with ctest and clang on Mac OS X.
Versions used are :
- clang 4.2, from XCode 4.6DP4 on Mac OS X 10.7
- cmake 2.8.10.2
In our ctest script, compilation is launched with 4 jobs (make -j4).
In our dashboard (and same thing when directly looking at the text output of the ctest process), we notice that some compilations outputs get mixed.
In this case we can see the beginning of one compilation process output starting in the middle of a previous compilation output.
This leads to some mixed outputs of two different compilation processes, that cannot be properly interpreted by ctest as warning, and are therefore displayed as errors.
At the end of this mail, an example of the kind of mixes we have.
Is anybody facing the same problem and is there a workaround available ?
Kind regards
Ananda
