One of my test cases needs sudo to run (its listening on privileged ports).
If I add
ADD_TEST( SERVER /usr/bin/sudo
${CMAKE_RUNTIME_OUTPUT_DIRECTORY}/Server${SUFFIX} --daemon )
CMake complains that it can¹t find sudo.
[ d042 ] make test
Running tests...
Test project /Users/richard/BUILD
Start 1: SERVER
Could not find executable /usr/bin/sudo
Looked in the following places:
/usr/bin/sudo
/usr/bin/sudo
/usr/bin/Release/sudo
/usr/bin/Release/sudo
/usr/bin/Debug/sudo
/usr/bin/Debug/sudo
...
However (on OS X and Linux) sudo is not readable (although it is
executable).
In Source/CTest/cmCTestTestHandler.cxx (line 1494) you¹re using
cmSystemTools::FileExists(attempted[ai].c_str() ) to test for the presence
of the testcase.
Looking in Source/kwsys/SystemTools.cxx line 919 shows that on non-Windows
systems its using access(path, R_OK), which checks to see if the path has
read permissions.
Might I suggest replacing the call to FileExists()
Source/CTest/cmCTestTestHandler.cxx in with a new test -
FileIsExecutable() since the only requirement is to be able to execute the
program, not read it.
Thanks,
Richard.
