The following issue has been SUBMITTED. ====================================================================== http://public.kitware.com/Bug/view.php?id=15003 ====================================================================== Reported By: Ryan Curtin Assigned To: ====================================================================== Project: CMake Issue ID: 15003 Category: CMake Reproducibility: always Severity: minor Priority: normal Status: new ====================================================================== Date Submitted: 2014-07-02 16:29 EDT Last Modified: 2014-07-02 16:29 EDT ====================================================================== Summary: depend.make ignores files with the same name Description: I've attached an interesting project that exposes a bug that is similar (but maybe not identical) to http://public.kitware.com/Bug/view.php?id=9354 . This occurred while working on mlpack ( http://www.mlpack.org/ ) which uses CMake, but I have reduced it to the simplest case I can think of.
We have a test file, 'test.cpp', which includes two files 'a.hpp' and 'b.hpp'. The file 'a.hpp' includes 'a/a.hpp' which in turn includes 'impl.hpp' located in the directory a/. The file 'b.hpp' includes 'b/b.hpp' which in turn includes 'impl.hpp' located in the directory b/. Then, the CMake configuration just makes a target 'test' that depends on test.cpp, and ideally CMake should figure out all the header dependencies correctly. However, when CMake is used to configure and build the target, the resulting depend.make file associated with the test target only contains a/impl.hpp and not b/impl.hpp. This means I can make changes to b/impl.hpp and recompile, but CMake does not detect the changes. Unfortunately I am not enough of a CMake expert to provide a patch, but I thought it would at least be useful to reproduce the issue. Steps to Reproduce: 1. unpack attached .tar.gz 2. use CMake to configure it 3. build the test target 4. run ./test, look, the output is complaints 5. modify b/impl.hpp and add vulgarities 6. make test 7. run ./test... no vulgarities! Additional Information: I tried with both CMake 2.8 and 3.0, so it is tested against the latest stable release of CMake in both the 2.x and 3.x branches. ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2014-07-02 16:29 Ryan Curtin New Issue 2014-07-02 16:29 Ryan Curtin File Added: cmake-test.tar.gz ====================================================================== -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
