The following issue has been SUBMITTED. ====================================================================== http://public.kitware.com/Bug/view.php?id=13074 ====================================================================== Reported By: Cesar Assigned To: ====================================================================== Project: CMake Issue ID: 13074 Category: CMake Reproducibility: random Severity: major Priority: high Status: new ====================================================================== Date Submitted: 2012-03-29 12:54 EDT Last Modified: 2012-03-29 12:54 EDT ====================================================================== Summary: Parallel builds fail consistently when embedding manifest Description: This happens due to a race condition in Microsoft Visual Studio 2008 when building things in parallel. Here's one example:
115>mt.exe : general error c101008d: Failed to write the updated manifest to the resource of file ".\Release\myprogram.exe". Access is denied. Of course, this happens more often when we're really trying to get a build for a customer, or when it is the nightly build that triggers regression tests. I know we can disable manifest generation with /MANIFEST:NO, but that's not an option - our software does need the manifests or we get the dreaded "side-by-side error"s. There doesn't seem to be a "proper solution" either. Here's a suggestion: allow me to specify an arbitrary pause, in seconds, between the linking and the mt.exe calls (I don't know if that is possible). A more involved solution would be to execute mt.exe as a post-build step, but for that I need CMake to pass /MANIFEST to the linker while not calling mt.exe after that automatically. Any other suggestions welcome. This, by the way, did not happen when using our old Makefile-based system, which called mt.exe right after the linker with no pauses. Then again, that was being executed from Cygwin and it was much slower. Steps to Reproduce: Build a large project in parallel. For my project, it fails 1 out of 3 or 4 times. ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2012-03-29 12:54 Cesar New Issue ====================================================================== -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
