I've just installed MSVC Express 2010 and loaded the solution as specified here: http://www.freertos.org/FreeRTOS-Plus/FreeRTOSPlusTCP/examplesFreeRTOSsimulator.html

The source code compiles but the build fails with this message: 1> Generating Code... 1>LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

I'm sorry if this is basic, but I was expecting the demo to work out of the box... I'm on windows 7 (x64), btw.

Thanks

Hi,

This looks like a good solution:

but I haven't come across this problem yet.

Just to satisfy myself, on a Win7 64-bit host and Visual Studio Express 2010 with service packs I tried downloading a clean FreeRTOS+TCP zip file and this is the build output I got:

Thanks for the posts! Applying the service pack fixed it.
