That's a hint, I changed my toolchain file "toolchain_ppc.cmake" to
the following:<br>
INCLUDE(CMakeForceCompiler)<br>
set(CMAKE_SYSTEM_NAME "Discovery")<br>
<br>
if(CMAKE_CROSSCOMPILING)<br>
message("Cross Compiling")<br>
endif(CMAKE_CROSSCOMPILING)<br>
<br>
# which compilers to use for C and C++<br>
set(CMAKE_C_COMPILER "C:/WindRiver/diab/5.9.0.0/WIN32/bin/dcc.exe")<br>
set(CMAKE_FORCE_C_COMPILER
"C:/WindRiver/diab/5.9.0.0/WIN32/bin/dcc.exe")<br>
set(CMAKE_C_FLAGS "-tPPCVLEEN:simple")<br>
<br>
Then I created a folder with the name Platform containing a file
with CMAKE_SYSTEM_NAME which is Discovery -> at this point I had
already problems, because CMake doesn't use as described the
filename with .cmake extension. The filename in the Platform folder
has to have the name from CMAKE_SYSTEM_NAME without the extension
.cmake (even the documentation says something different). I checked
this by adding the output of a message("SYSTEM_NAME=Discovery").<br>
<br>
The Platform/Discovery file contains the lines:<br>
message("SYSTEM_NAME=Discovery")<br>
set(CMAKE_FORCE_C_COMPILER
"C:/WindRiver/diab/5.9.0.0/WIN32/bin/dcc.exe")<br>
set(CMAKE_C_COMPILER "C:/WindRiver/diab/5.9.0.0/WIN32/bin/dcc.exe")<br>
set(CMAKE_C_FLAGS "-tPPCVLEEN:simple")<br>
set(CMAKE_FORCE_C_FLAGS "-tPPCVLEEN:simple")<br>
set(CMAKE_FORCE_CXX_COMPILER
"C:/WindRiver/diab/5.9.0.0/WIN32/bin/dcc.exe")<br>
set(CMAKE_CXX_COMPILER
"C:/WindRiver/diab/5.9.0.0/WIN32/bin/dcc.exe")<br>
set(CMAKE_CXX_FLAGS "-tPPCVLEEN:simple")<br>
set(CMAKE_MAKE_PROGRAM
"D:/novero/Discovery/impl/win32/nmake/nmake.exe")<br>
<br>
Then I call from the command line the CMake tool with the
parameters:<br>
D:\novero\Discovery\impl\target\CarIF_Appl\output>cmake -G "NMake
Makefiles" -D CMAKE_TOOLCHAIN_FILE="..\toolchain_ppc.cmake" ..<br>
<br>

1.) with the output SYSTEM_NAME=Discovery I can see that the
platform file is used<br>
2.) the compilation doesn't complete, because the CMAKE_C_FLAGS are
still not used<br>
3.) why do I have to have a CXX (C++) compiler, even if I don't need
it in my embedded solution<br>
4.) is there any reason why CMake needs to know my system? I want
just to compile some files... (wondering)<br>

My problem (the error) already occurs in the toolchain file, this means before the CMakeLists.txt is read. So far it is total independent of the entries in the CMakeLists.txt!
I have added the line:
message ("Mein CMakeLists.txt File")
in top of my CMakeLists.txt and would assume that there is an output on the console with the string, but it isn't.
The output is stopped while parsing the toolchain file and determining the compiler.

That's what I was about to say.
Read <a class="moz-txt-link-freetext" href="http://www.vtk.org/Wiki/CMake_Cross_Compiling">http://www.vtk.org/Wiki/CMake_Cross_Compiling</a> carefully
you'll see that you may have to write a
Platform/${CMAKE_SYSTEM_NAME}-<compiler>.cmake file
in order to inform CMake about your particular compiler compilation FLAGS.
Doing it in CMakeLists.txt may already be too late.
Nevertheless it puzzles me that it works on Linux and not on Windows...
I'm no expert concerning Cross-compiling with CMake so I let others
take over this discussion.
