Building OpenSSL for Windows CE requires the following external tools:
* Microsoft eMbedded Visual C++ 3.0
* wcecompat compatibility library (
* Optionally ceutils for running automated tests (
You also need Perl for Win32. You will need ActiveState Perl, available
Windows CE support in OpenSSL relies on wcecompat and therefore it's
appropriate to check for updates in
case of compilation problems. As for the moment of this writing version
1.1 is available and actually required for WCE 4.2 and newer platforms.
All Windows CE specific issues should be directed to
The C Runtime Library implementation for Windows CE that is included with
Microsoft eMbedded Visual C++ 3.0 is incomplete and in some places
incorrect. wcecompat plugs the holes and tries to bring the Windows CE
CRT to a level that is more compatible with ANSI C. wcecompat goes further
and provides low-level IO and stream IO support for stdin/stdout/stderr
(which Windows CE does not provide). This IO functionality is not needed
by the OpenSSL library itself but is used for the tests and openssl.exe.
More information is available at
Setup the eMbedded Visual C++ environment. There are batch files for doing
this installed with eVC++. For an ARM processor, for example, execute:
> "C:\Program Files\Microsoft eMbedded Tools\EVC\WCE300\BIN\WCEARM.BAT"
Next indicate where wcecompat is located:
> set WCECOMPAT=C:\wcecompat
Next you should run Configure:
> perl Configure VC-CE
Next you need to build the Makefiles:
> ms\do_ms
If you get errors about things not having numbers assigned then check the
troubleshooting section in INSTALL.W32: you probably won't be able to compile
it as it stands.
Then from the VC++ environment at a prompt do:
- to build static libraries:
> nmake -f ms\ce.mak
- or to build DLLs:
> nmake -f ms\cedll.mak
If all is well it should compile and you will have some static libraries and
executables in out32, or some DLLs and executables in out32dll. If you want
to try the tests then make sure the ceutils are in the path and do:
> cd out32
> ..\ms\testce
This will copy each of the test programs to the Windows CE device and execute
them, displaying the output of the tests on this computer. The output should
look similar to the output produced by running the tests for a regular Windows
