Hi List,
Today I started to port my Ada project (Windows, MinGW, Ada cmake
files from plplot) from cmake 2.4.7 to cmake 2.6.
Now I have the problem that cmake doesn't want to use gnatmake anymore
and says that gnatmake is broken.
I summarized the CMake Ada language support status in
http://www.cmake.org/pipermail/cmake/2008-May/021911.html which includes a
simple Ada test project I have put together. That simple test project
works
fine for 2.4.x, but does not work for 2.6.0 (as you have also found for
your
own project). The problem is the language support infrastructure for 2.6.0
is different than 2.4.x. At that time I was hoping to figure out the 2.6.0
Ada issues fairly quickly, but I could not do that, and something else has
now intervened. So the planned PLplot transition to CMake 2.6.x (and also
the transition you were hoping for for your own project) will have to wait
until I have more time to fix the Ada 2.6.x issues unless someone else can
fix those issues first.
Add this to your language support file:
SET(CMAKE_Ada_OUTPUT_EXTENSION_REPLACE 1)
This will tell CMake that the object files should not keep the source
file extension.
You CMake developers are great! This fix solved all problems for the simple
test project I referred to in my answer to Bill if I use the default static
build for the test Ada library.
However, if I build a shared version of that library (possible as of
revision 8495), then the "hello" executable cannot find that library for
2.6.0 at run time although no such problems occur for 2.4.8. A
LD_LIBRARY_PATH workaround on Linux exists for 2.6.0, but that should not be
necessary.
The issue is that for 2.4.8, rpath is set appropriately for the Ada executable
to find the Ada shared library that was built, but for 2.6.0, rpath is not
set at all. Note, I do nothing special with rpath for this simple test
project so it just has the default rpath behaviour. But that default
behaviour seems to have changed between 2.4.8 and 2.6.0 (probably due to
some limitation in my Ada language support files).
I hope this one is as easy to solve as the OUTPUT_EXTENSION issue.
