Hi again,
I've installed the 2008 Express version, and it's not possible to
install any Mobile SDK afterwards. Microsoft supports Smat Devices in
every version except for the Express one. Even if you hack the msi file
to install (not checking if the right VS version is installed), it is
still not possible to use it because it does not include the compilers
for smart devices. In my opinion this means that it is useless to try
cross-compiling on windows anyway if you just got the Express versions
and not professional, team or whatever.

Hi,
well, I have not tested it with the Express versions of 2005 or 2008
(I think Microsoft already stopped support of Express 2005, so there
is only Express 2008 left). I will try to get it to run with an
Express Version of 2008, although I have no idea of support for
Windows Mobile devices in this version. If there is no support, then
the generators will clearly only work for the commercial versions.
In principle the generators will produce all possible configuration
targets (times all default configs, like minrel, minsize, debug and
release) as long as you omit the SDK entry in the cache file (to be
copied prior to running configure). However, this is quite a bad
solution originating from the beginnings of writing the patch as a
fallback solution, and one should use the generator in a different
way; by now I did not think about building a project for multiple
different target machines in one configuration/build step, and I guess
also in your CMakeLists.txt you might have to include different
configuration sections for different machine types, e.g. one for ARM
and one for SH4 which complicates the entire process. If your settings
are so different that you nearly have to use two different toolchain
files, it might be quite a bad idea to build only one single project.
I cannot try anything else than the WinCE or Windows Mobile SDKs for
ARM here because I have no SH4 machines, but configuring a project for
other platforms should basically work the same way. Clearly, in case
you want to really run it with different cross-compile settings (like
to compile it for SH4 with SH4 settings and to compile it for ARM with
ARM settings) I think you should simply pre-configure the cache file
to build the project for this platform only, and then repeat the
process for any other platform. In principle, the cache file sets the
toolchain file and - at the same time - adds the missing capability to
choose the right SDKs. In one case you would preconfigure the cache
file to use a toolchain file containing all the SH4 settings, and
another toolchain file to set all ARM specific settings. If you use a
common toolchain file like yours WinCE one, you just choose the SDK to
use and set some flag like CONFIG_IS_SH4 or CONFIG_IS_ARM and you get
the correct configuration in Visual Studio and choose the correct
configuration section from your CMakeLists.txt file.
In my case for example, I build it for Win32 and Windows Mobile 5 in
separate directories which works great. If you install an SH4 SDK and
an ARM SDK, preconfigure the cache files and configure/build in
separate directories with different settings it should work almost the
same.

Configuring our project fails during the CMakeTestCCompiler.cmake
tests, because it tries to execute the generated project files with
VCExpress wich has no SDK configured - and I doubt that it supports
multiple SDKs at all. I am investigating that right now.
Changing the order in which CMakeVS8FindMake and VS9 respectively,
search for devenv and VCExpress fixed the issue.
Before I stopped for today I also discovered that there is a way to
magically set the UNDER_CE macro depending on the SDK used. For NMake
Makefiles I did that depending on the given CMAKE_SYSTEM_VERSION. I
will try to add that tomorrow.
As far as I understand, with the new generators for 2005 and 2008,
cmake will create project files for multiple cross compilation targets
at once? So if one has a SH4 and a ARMV4 CE SDK installed, we would
get a visual studio project that can be switched between these two
configurations (times the release/debug configurations), but there
would be only a single execution of the CMakeLists.txts with a
probably invalid set of CMAKE_SYSTEM_* variables. So if a project for
example modifies the set of source files for a target, or sets its own
set of platform describing cmake variables based on the given CMAKE_*
variables, we would break that project when the new generators are
used?
kind regards,
Andreas Pokorny
