Thanks, David I constructed a custom build command that runs a batch file and outputs a text file solely via the VS10 IDE... and there was no %(Outputs) in the vcxproj file.

Thanks for the report, David This bug is quite possibly a report of the same thing, although, as noted in the bug, I could not reproduce the problem: http://public.kitware.com/Bug/view.php?id=12302 Drat! This doesn't actually seem to help. I'll see if I can create a smaller test program that illustrates the issue. Does anyone know of a way to figure out why VS wants to build something similar to a make -d? It would be really helpful to understand what is causing VS to rebuild stuff. James I've been buried in this for the past day and I think I might know what is going on. Unfortunately there doesn't appear to be an elegant solution to this other than perhaps filing a bug with Microsoft. From my experimentation, it appears that custom build rules require being registered in the custombuild.command.1.tlog file that is put into the %(Intermediate Directory) location of the project. Since this location is generally different for Debug and Release builds, each configuration needs to run *all* the custom build rules at least once to populate this file. This the output from MSBuild when more detailed logging is enabled. Forcing rebuild of all source files due to missing command tlog D:\win7x64\bugs\cmake-extra-build\VS-2010\cat-file\Release\custombuild.command.1.tlog. (TaskId:14) I'm not sure how to work around this aside from putting all non configuration dependent targets into a special project that has an intermediate directory that isn't %(Configuration) dependent. That doesn't seem like a lot of fun. Why MSBuild can't simply just populate the files without actually running the build commands if the dependencies are met seems like a little bit like a missing feature, however it could be the mechanism to determine dependencies relies on that file being populated. Unfortunately for me where I have *many* non-configuration dependent custom build rules I have to rebuild all the files for each configuration. :( James -- 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
