Sorry for the late reply. My previous reply was waiting for moderator approval because it was too large. Here is a shortened one.

In a project where I have like 10 dylib to build, they all use the same precompiled header. For the 3 first dylib, all goes fine but for the 4th, I get an error that says about the precompile header : "No such file or directory".


I checked the precompiled header for all the projects from the build results and the path is exactly the same for all. It looks like the precompiled header disapears after a while.


What should I do to keep my precompiled headers for ever?


Is it actually a good thing to store the precompiled headers in the éLibraryéCachesé ?


Please post the build transcript lines that show the ProcessPCH step that builds the precompiled header and the CompileC step that fails because it can't find the precompiled header, including the actual and complete error messages from the build transcript.

Also indicate whether this is in Xcode 1.5, 2.0, 2.1, 2.2DP1, or 2.2DP2.
Xcode 2.2 (Seed) (622.0)
 
Here is the transcript lines. I included one build that succeeded and the one that failed. And because there is a link just before the one that fails, I included it too. But I removed all the source relatred errors and warnings except the ones pertaining to the missing precompiled header to shorten it. Thanks for looking into this :
