I did a full rebuild as well as another attempt at a subbuild. I got the same environment variable problems I had before on the subbuild. Full rebuild: W:\dward_JELProject\JEL>C:\SparkBuild\ --wi…

I'm trying SparkBuild for the first time. All of our makefiles start with an include of common definitions in file $(__buildTop)/mk/top.mk. This works for the first makefile, but when SparkBuild en…

Thanks David, it looks like this is a bug in emake related to the subbuild feature. The issue is that environment variables are stored in the subbuild database with the name converted to uppercase, so when the environment is recreated in a subsequen…

The dependencies tracked in the sparkbuild db depends on how you structured your makefiles. If you made *.cpp files depend on outputs generated by other submakes, then yes, every time you add a .cpp file to your build you have to regenerate the data…

EM: I did one more thing. Instead of doing a clean first, I just built everything with gen=1. I didn't build much because not much was changed, but it did go through all of the makefiles. This built the database, but gives me the original problem I…

EM: Did a clean and a full build. Now I can't get it to even try to build targets in other makefiles. After the full build, I deleted a library that is built in a different makefile to see if it would be rebuilt, but all I get is an error. W:\dwar…

I see that the submake that is missing the environment variable is actually created as a subbuild job, which means that the environment it uses is coming from the subbuild db. That means that your subbuild db may be invalid -- is it possible that it…

Can you attach that XML to your post, rather than pasting it inline? The site seems to have swallowed most of the XML tags. Click the "Upload Files" link beneath the text editing field when you write your reply. Thanks.

EM: Line 31 of the makefile is: include $(__buildRoot)/mk/subdir.mk Note that this is not the makefile that is first executed. This is in a subbuild makefile in a different directory. And this all works for a build from the top-level down plus l…

David, Are you certain this only breaks with SparkBuild emake? I crafted a simple test case based on the information you provided here and it seems to be working correctly as expected, so I think there must be more going on in your environment than…

Can you show us the command-line you use to invoke SparkBuild emake?
