Summary0009908: *.Cxx files in the windows version
DescriptionI not sure it's an bug but here it comes:


When adding files to libraries or exec in CMakeLists.txt files I used the extension .cxx on the files. As the example project http://www.cmake.org/cmake/help/examples.html [^] explains, but that keeps yielding an error upon generation:

CMake Error in Demo/CMakeLists.txt:
  Cannot find source file "demo.cxx". Tried extensions .c .C .c++ .cc .cpp
  .cxx .m .M .mm .h .hh .h++ .hm .hpp .hxx .in .txx

But when I changed the file extension in the CMakeLists.txt to .cpp it works, but the error states that CMake have tryed with all the mentioned extension, which doesn't seem to be the case. I haven't tried 2.8 yet, the observation is made with CMake 2.6-patch4.
I'm happy my project is working, but this might help other newbies to CMake :)

 .cxx files should work just fine. That error means demo.cxx was not found by CMake. If you could give a complete example (tar or zip) that shows the problem we can figure out what is going wrong.

 Hi

I've uploaded my project, it contains a readme.txt with version and etc. details.

 Uhh....

ls
CMakeLists.txt hello.cpp hello.h

# Create a library called "Hello" which includes the source file "hello.cxx".
add_library (HelloLib hello.cxx)


You have to actually rename the file on disk to .cxx instead of .cpp for this to work....

 thanks, but how come the error response tell me that it tried all the listed extension?

Tried extensions .c .C .c++ .cc .cpp
  .cxx .m .M .mm .h .hh .h++ .hm .hpp .hxx .in .txx

It should have found the .cpp files, if it tried adding the extension or should the CMakeLists.txt just state:

# Create a library called "Hello" which includes the source file "hello.cxx".
add_library (HelloLib hello)

I don't know the insides of CMAKE, but is it trying hello.cxx.XXX instead of hello.XXX, where XXX denotes all the extensions in the error message or how does CMAKE handle this?

 What it tried was hello.cxx.cpp, if you did add_library(HelloLib hello) then it would work. However, we are considering deprecating this type of thing anyway.
