Summary0011584: Temporary files overlap in VS2010 generator
DescriptionI have a big project which works fine with CMake on VS2005, VS2008 and Unix generators. It consists more than 100 executables & dynamic link libraries.

It contains a lot of small examples,
such as ADD_EXECUTABLE(Example1 main.cpp).

In VS2010 I have the following error in the different small examples, such as:

  CMake does not need to re-run because D:\ProjectName\examples\ReportExample\CMakeFiles\generate.stamp is up-to-date.
C:\Program Files\MSBuild\Microsoft.Cpp\v4.0\Microsoft.CppCommon.targets(151,5): error MSB4018: The "CustomBuild" task failed unexpectedly. [d:\ProjectName\examples\ReportExample\ReportExample.vcxproj]

Please note that I am using /m:1 switch for msbuild.exe utility,
so, I am using 1 core for building this project.

I think that previous or some other project (as part of my big project) used the temporary cmd file (i.e. Temp\7bf85b669bd34561b56a1267d38c2645.cmd) for compiling and the current project is trying to use the exactly same name.

Is any work-around for this problem?
Steps To ReproduceI can not figure-out a small example to reproduce, sorry

A similar issue with multiple custom commands trying to write output to the same log file simultaneuosly was fixed with this commit:

http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=ed37fc3ea398b03bbba175ae337f14b6af58daee [^]

That change should be in the CMake 2.8.3 release.

Since you cannot provide a small reproducible example, can you give us access to your project instead? (Or is it private?)

Seems like any large project trying to build in parallel would hit this sort of issue.

Do you have targets with same name, but in different directories? Maybe VS10 uses the target name as the base name for its generated *.cmd files, and parallel stuff just won't work with multiple targets having the same name...?

Sorry, it is a private project. So, I can not share.

No, all targets are unique.

I am using msbuild /m:1 option. It specifies that 1 core should be used for compilation. Will be parallel compilation used?

Thank you for the advise

another strange thing - main project is being compiled twice.

I think that I have found a reason of such behavior.

I terminated my previous build (by control-c sequence).
And the temporary files are from previous build.

Closing bug. If the only problem here is that Visual Studio leaves junk around when the user hits Ctrl+C to cancel a build... then it is not a problem that CMake can actually solve.

Thanks for the udpate.
