Problem
After I installed the binary ACS installation, no kernel modules can be built / kernel module build fails due to missing include files
Solution
The reason is simple. The standard installation place for the RTOS patched kernel is /usr/src/kernels/2.6.15.2-rtos-3.3. If you installed your kernel with the buildRTOS-/installRTOS-scripts, it depends on your kernel configuration file how the directory is actually labeled. Just make the symlink /alma/ACS-X.Y/rtlinux point to your kernel directory.
