I can't get the CircleOS 3.8 (nor 3.7) to build. The  build  fail  on the very first c file compile 
 
----------------Build Started: 'Circle' in configuration 'Standard'-------------------------- 
Building C:\Program Files\Raisonance\Ride\lib\ARM\circle\OS\circle_api.c 
Build failed 
Without much details on the message hard to find  what's wrongs. 
I basicly unziped the package to "[Ride7_INSTALL_DIR]\Lib\ARM", open the projects with ride and tried to build 
i've tried both Circle.rprj or Primer2_Circle.rprj  project  same 
 
May it be that i did install the latest ride7 (v 7.28.10.0075)  + arm rkit (1.24.10.0050) directly from the  web not using  the old cd that was coming with the pimer2 ?
Am certainly missing something obvious but what ? any help welcome
