Out of the box Rhapsody does not support Visual Studio 2008 but it's pretty easys to make it working. So if you have VS2008 just follow the instructions:
(1) During Rhapsody installation select "Check for Real Time OS Settings"
(2) Select Visual Studio 2005
(3) Locate in your Visual Studio installation directory the file
vcvars32.bat - remember or copy the path to it (i.e. C:\Program Files\Microsoft Visual Studio 9.0\VC\bin\vcvars32.bat)
(4) After Rhapsody installation in the folder rhapsodyInstall\Share\etc open the file msmake.bat and point to your vcvars32.bat file.
So the content of the file should look like this
@echo off
if "%2"=="" set target=all
if "%2"=="build" set target=all
if "%2"=="rebuild" set target=clean all
if "%2"=="clean" set target=clean
call "C:\Program Files\Microsoft Visual Studio 9.0\VC\bin\vcvars32.bat" x86.
echo ``nmake.exe
nmake /nologo /S /F %1 %target% %3 %4 %5 %6
(5) Start Rhapsody and create a new Rhapsody project that uses the Microsoft configuration settings
(6)Select Code > Build Framework.
You're now able use VS2008 ...
