Nested cmake projects lead to too many command line flags for specific file. #26

Closed sbroberg closed 8 years ago

sbroberg commented 8 years ago

We have a project that looks something like this:

product/CMakeLists.txt
product/daemon/CMakeLists.txt
product/daemon/src/CMakeLists.txt
product/daemon/tests/CMakeLists.txt
product/monitor/CMakeLists.txt
product/ui/CMakeLists.txt

When we open a file that is in product/daemon/src, it appears to be using all the -I options, -include options, etc. for all projects that life under the product directory (all those listed above), instead of just those generated by the inclusion of the CMakeLists files that lead back to the root (the ones in product, product/daemon, and product/daemon/src).

You can see an example of this in my other issue, https://github.com/atilaneves/cmake-ide/issues/24.

I've tried creating a .dir-locals.el in the product/daemon/src directory that points to either the CMakeLists.txt file in product/daemon/src, or to the one in /product, but the result is the same:

((nil . (
     (cmake-ide-dir . "/Users/stebro/product/daemon/src")
         )))

Is there some other way I'm supposed to configure things to see only the relevant CMakeLists.txt files in a project?

atilaneves commented 8 years ago

cmake-ide-dir wouldn't help you, that's supposed to be the build directory. As for the flags, I use cmake-ide daily on a project with nested CMakeLists.txt. The way CMake works is that flags defined in a parent directory are inherited. If those flags show up in compile_commands.json, then that's how it's supposed to be. Could you check? It doesn't seem like a bug to me.

Here is the compile_commands.json clause for one of my files:

I wonder if this could be related to the other issue I filed, where the quoted string in the compile option is not being handled correctly. Perhaps it is causing subsequent files in the compile_commands.json file to be included? I can do a quick check.

atilaneves commented 8 years ago

Maybe. I can't tell with what you've posted.

sbroberg commented 8 years ago

Quoted strings are not the issue. I have a new project, much simpler than the old one, which exhibits the same issue - compile options specific for one subproject are being included other subprojects. I can send you zipfile if you want to test.

atilaneves commented 8 years ago

Don't know about a zipfile, but something to go on would help, yes.

atilaneves commented 8 years ago

I can't tell if the issue is fixed or not, so I'll close this. If it still exists, please reopen with enough information about your project to enable a fix.
