| Platform | Linux | OS | Ubuntu | OS Version | 12.04 | ||||
| Product Version | CMake 2.8.10.2 | ||||||||
| Target Version | Fixed in Version | ||||||||
| Summary | 0013938: Incomplete header dependencies generated | ||||||||
| Description | I constructed a minimal example which reproduces the issue. The include tree is: main.cpp -> a/a.h -> x.h (a.h includes x.h without path and x.h is in a/) \-> c/c.h -> x.h (c.h includes x.h without path and x.h is in c/) Now cmake detects the dependency only for one of the two x.h! Note: I even added all files to the executable add_executable(main main.cpp a/a.h a/x.h c/c.h c/x.h) | ||||||||
| Steps To Reproduce | 1. Compile the project. * project build must be successful! 2. Change a/x.h and check if the change is picked up by the build system 3. Change c/x.h and check if the change is picked up by the build system Either step 2 or step 3 should fail! | ||||||||
| Additional Information | I ran the following command in the build directory: $ rgrep "x.h" * CMakeFiles/main.dir/depend.make:CMakeFiles/main.dir/main.cpp.o: /home/poenitz/Desktop/bugreport/src/a/x.h CMakeFiles/main.dir/CXX.includecache:x.h CMakeFiles/main.dir/CXX.includecache:/removed/bugreport/src/a/x.h CMakeFiles/main.dir/CXX.includecache:/removed/bugreport/src/a/x.h CMakeFiles/main.dir/CXX.includecache:x.h CMakeFiles/main.dir/CXX.includecache:/removed/bugreport/src/c/x.h CMakeFiles/main.dir/depend.internal: /removed/bugreport/src/a/x.h | ||||||||

Can you try to #include "./x.h" in both places and see if that helps? Sadly the C/C++ standards do not say that "" includes should look in the local directory first. This is insane, but sadly the truth. E.g. MSVC compilers handle <> and "" includes exactly the same AFAIK. |

No it does not help. Writing full project paths (a/x.h and c/x.h) resolves the issue. But isn't it irrelevant? I think that from a C++ point of view there is no collision here and building it works just fine. Isn't the only problem that cmake somehow overwrites one dependency because the file names are equal? |
