... Remove the sdk.h.gch manually and see if this fixes it.
yes i did that, but it didn't fix it,
btw.
i discovered, the following points
1.) sdk_precomp.h isn't set to precompiled state in the CodeBlocks-unix.cbp project file.
2.) the update script doesn't strip the files in the output folder (strip commands remarked)
are they intended or by mistake ?
thx tiwag
