Hi Bill:
The Fortran 95 issue turned out to be that the default location for Fortran
95 modules has been moved from the top-level ${CMAKE_BINARY_DIR} to the
more
logical subdirectory (in our case ${CMAKE_BINARY_DIR}/bindings/f95) where
the associated fortran library was created in the build tree. For PLplot
this required an INCLUDE_DIRECTORIES change (to build Fortran 95 examples
using the generated module files) as well as a change in build-tree
location
for the generated Fortran modules that we install.
Since these changes are CMake version dependent, I used the following
command to distinguish the 2.4.x version from later versions:
if(CMAKE_CACHE_MAJOR_VERSION EQUAL 2 AND CMAKE_CACHE_MINOR_VERSION EQUAL 4)
This method appears to work (I get good results now for both the 2.4.8 and
cvs versions of CMake), but if there is a better way to distinguish CMake
versions from within cmake, please let me know.
CMAKE_MAJOR_VERSION and CMAKE_MINOR_VERSION should be set:
http://www.cmake.org/HTML/CMake-2.5.html#command_CMAKE_MAJOR_VERSION
http://www.cmake.org/HTML/CMake-2.5.html#command_CMAKE_MINOR_VERSION
Although this build-tree location change for the generated fortran modules
is a backwards incompatibility, I recommend you just accept that
incompatibility for your next release. Fortran support in 2.4.8 basically
sucks so I believe any CMake Fortran user would be happy to adopt a new
version with Fortran properly supported for the small expense of adjusting
for the backwards incompatibility created by adopting a much more logical
location for the generated module files.
Where did the modules go in 2.4.8?
