[cmake-developers] CPackRPM not dealing correctly with symlinks

[Attila Krasznahorkay]

Hi Brad,

I did. Then I get:

CMake Error at /afs/cern.ch/work/k/krasznaa/public/cmake/3.5.0/share/cmake-3.5/Modules/CPackRPM.cmake:981 (string):
string begin index: 164 is out of range 0 - 156 
Call Stack (most recent call first): 
/afs/cern.ch/work/k/krasznaa/public/cmake/3.5.0/share/cmake-3.5/Modules/CPackRPM.cmake:1625 (cpack_rpm_prepare_install_files) 
/afs/cern.ch/work/k/krasznaa/public/cmake/3.5.0/share/cmake-3.5/Modules/CPackRPM.cmake:1787 (cpack_rpm_generate_package)

You can find the full output here:

Note that when I tried to build the project in a build area with a shorter path, then the RPM building succeeded. Just because by chance in that case in the expression

string(SUBSTRING "${SYMLINK_POINT_}" ${WDR_LEN_} -1 SYMLINK_POINT_WD_)

the work directory length was shorter than the length of the path outside of the project.

Of course this is the code that we're talking about:

Cheers,
             Attila
