[CMake] CMake 2.8.2 with WindRiver diab compiler dcc.exe/dplus.exe on WinXP: CMake Error: Could not COPY_FILE. while detecting compiler ABI

[Molsen, Hannes]

[SOLVED]

Hi all,

My problem is completely solved and the output is now as follows:
 
-- The C compiler identification is Diab
-- The CXX compiler identification is Diab
-- Check for working C compiler: D:/CCView/tools/tornado/host/diab/WIN32/bin/dcc.exe
-- Check for working C compiler: D:/CCView/tools/tornado/host/diab/WIN32/bin/dcc.exe -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Check for working CXX compiler: D:/CCView/tools/tornado/host/diab/WIN32/bin/dplus.exe
-- Check for working CXX compiler: D:/CCView/tools/tornado/host/diab/WIN32/bin/dplus.exe -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Configuring done
-- Generating done
-- Build files have been written to: D:/CCView/binaries/PPC603diab/rat/Framework

Isn't that beautiful? :-)

So, what was the problem?

As I said, we only build libraries, no executables. Therefore I disabled the linking to an executable via compiler flag (dplus.exe -c), so the compiler stopped after assembly. Now that I knew, that COPY_FILE was actually looking for an executable for the ABI detection, I just adapted my flags and now everything works :)

I still don't fully understand why this COPY_FILE error does not occur if I rerun the cmake command in --debug-trycompile mode, but now everything works fine, so I don't care :)

Thank you all for the help!

This comes from Sources/cmCoreTryCompile.cxx, there FindOutputFile() 
apparently was not successful in finding the linked executable.
The value of CMAKE_EXECUTABLE_SUFFIX is used there.
You need a valid setpu for creating executable, i.e. the suffix must be set 
and also the CMAKE_C/CXX_LINK_EXECUTABLE variables must be set properly.

Can you please post the CMakeOutput.log and CMakeError.log from when that 
happens ?

You may also dig into the code and check what's going wrong :-)
