After trying to build a WinCE OS image for ARM V4 I encountered the following error
NMAKE : fatal error U1073: don't know how to make 'C:\WINCE600\public\common\oak\lib\ARMV4I\retail\lmemhs.lib'
Then I decided to run an Advanced Command "Rebuild Current BSP and Subprojects" and I found next error.
BUILD: [01:0000002558:ERRORE] NMAKE : U1073: don't know how to make 'C:\WINCE600\OSDesigns\PENTA_ARM_PC\PENTA_ARM_PC\Wince600\SMDKC100_ARMV4I\cesysgen\oak\lib\ARMV4I\retail\gpe.lib' BUILD: [01:0000002560:ERRORE] NMAKE.EXE TargetLibFiles -i -c BUILDMSG=Stop. BUILDROOT=C:\WINCE600\PLATFORM\SMDKC100 CLEANBUILD=1 LINKONLY=1 NOPASS0=1 failed - rc = 2
What does this mean ? Why these files are missing? Are they part of the Win CE or the ARM BSP ? I am using Win CE 6.0 Trial.
Since GPE stands for Graphics Primitive Engine I would say that your BSP is encountering a problem and is not building properly.
You mentioned in comments that you did not install ARM support on your development environment, and you also said that your target system is an ARM device. It turns out that you cannot build an ARM platform if you do not install ARM support on your development environment.
It seems you will have to re-install (or install in another system) your development environment with ARM support, and apply a sysgen operation on your solution.
