ccmake error

[sellberg]

I tried to install libspimage on a new computer but got an error I haven’t seen before (I have used cmake 3.2.3 before, now I installed cmake 3.9.0 from brew). It seems to be related to some new CMake policy related to RPATH:

https://cmake.org/cmake/help/v3.9/policy/CMP0068.html

Have you seen this before? I tried to set the INSTALL_NAME_DIR explicitly in the RPATH part (see starred ** rows below) of /libspimage/CMakeLists.txt, but no luck so far.

Any idea how to solve it?

Cheers, Jonas

# when building, don't use the install RPATH already

When pressing g in ccmake:

CMake Warning (dev):
   Policy CMP0068 is not set: RPATH settings on macOS do not affect
   install_name.  Run "cmake --help-policy CMP0068" for policy details.  Use
   the cmake_policy command to set the policy and suppress this warning.

   For compatibility with older versions of CMake, the install_name fields for
   the following targets are still affected by RPATH settings:

    _spimage_pybackend
    spimage

 This warning is for project developers.  Use -Wno-dev to suppress it.

When compiling library with make:

src/CMakeFiles/_spimage_pybackend.dir/flags.make:10: multiple target patterns. Stop. make[1]: [src/CMakeFiles/_spimage_pybackend.dir/all] Error 2 make: *** [all] Error 2

I think the warning is probably unrelated to the error. Did you try to remove the build directory and try again?

[FilipeMaia]

I tested with cmake 3.9.1 without problems.

[sellberg]

Thanks for testing it, yes I've removed the directory and tried several times.

I'll go through the configurations and the dependencies again to check I haven't missed anything. I noticed my installation of CUDA does not appear to pick up the graphic card correctly, but I don't think it is related to the make error.

[FilipeMaia]

Can you turn on CMAKE_VERBOSE_MAKEFILE and paste the error output?

@sellberg Did you manage to fix this? I recently got the same error, which was caused by a syntax error in an underlying python script (part of the libspimage build). The problem became clear when looking at the src/CMakeFiles/_spimage_pybackend.dir/flags.make file...
