The example is very zippy for me, but I had to change to using a
different compiler because I do not have pgf90 installed. I tried
both GNU on Linux and XL on AIX. I wonder if cmake_copy_f90_mod
has trouble with the pgf90 module files. We do have tests running
nightly for that platform, but they would not reveal a delay if
the result is correct.
The log you sent is inconclusive. I do not think the lines are
appearing in the order they are produced. The make invocation
you mention above *is* executing cmake_copy_f90_mod.
After running the initial make to build the first time, edit the
file "CMakeFiles/mytest.dir/depend.make". There should be a block
like this:
CMakeFiles/mytest.dir/execute.mod.proxy:
CMakeFiles/mytest.dir/exec.f90.o.provides
CMakeFiles/mytest.dir/exec.f90.o.provides.build:
$(CMAKE_COMMAND) -E cmake_copy_f90_mod inc/mod/execute
CMakeFiles/mytest.dir/execute.mod.stamp GNU
$(CMAKE_COMMAND) -E touch
CMakeFiles/mytest.dir/exec.f90.o.provides.build
CMakeFiles/mytest.dir/build: CMakeFiles/mytest.dir/exec.f90.o.provides.build
Add an "echo" before and after the cmake_copy_f90_mod line to
confirm whether the delay is there or not.
Thanks,
-Brad
