This was not a problem in WiX 3.5, but apparently as part of 3.6 support was added to the MSBuild targets for "incremental builds" by testing the timestamps on all input files to the link task to see if they were newer than the output files. I haven't been able to find any documentation - Bob Arnson mentions it at the end of this thread in May 2011,
http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Developer-with-WiX-experience-needed-proper-incremental-build-support-td6380785.html#a6383958 and it's mentioned with a single line in the 3.6 release notes, ".wixproj MSBuild projects support incremental build." http://wix.codeplex.com/releases/view/93929 This is a nice facility, although it would have been even nicer with more information and maybe an option to turn it off. Anyway, my problem with it is that when I have the C++ runtime merge module in my project this forces a link to be done every time, even if no input is changed. As far as I can determine the processing of the merge module involves the creation of three temporary files: C:\Users\rp\AppData\Local\Temp\4q3ufw1n\MergeId.49012\F_CENTRAL_msvcp110_x86.D371D00B_69EC_3F8E_A622_74710A89ADC1 C:\Users\rp\AppData\Local\Temp\4q3ufw1n\MergeId.49012\F_CENTRAL_msvcr110_x86.D371D00B_69EC_3F8E_A622_74710A89ADC1 C:\Users\rp\AppData\Local\Temp\4q3ufw1n\MergeId.49012\F_CENTRAL_vccorlib110_x86.D371D00B_69EC_3F8E_A622_74710A89ADC1 I've extracted these filenames from the BindContentsFileList file, and I see them in the MSBuild log. I've never actually seen these files themselves with my own eyes - they are apparently created, consumed, and then deleted so quickly that human reflexes can't cope. But my guess is that they have a timestamp of "now", instead of being given a timestamp corresponding to the merge module, and this sabotages the incremental build testing. Which in turn sabotages all of the following incremental builds in the overall project. For now I've modified the WiX target so the link task no longer includes "_BindInputs" as part of its Inputs= list. Have I understood the situation correctly? -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Project-with-merge-modules-defeating-incremental-build-facility-tp7584279.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Everyone hates slow websites.
