Description Vladimir Kvashin 2016-04-27 16:28:29 UTC
Now the most perfect technique for project discovery is interception is preloading a shared library that interposes exec* calls.

However sometimes this does not work. In particular it does not work on modern Macs.

I think a wrapping technique should be used in addition to that. I mean that there should be a scripts with names gcc, g++, cc, CC, etc that log parameters and delegate execution to "real" compilers.

Comment 3 Alexander Simon 2016-04-29 08:33:25 UTC
Investigation:
1. This technique works on Mac. The main problem is how to explain user that (s)he heeds a tool collection wrapper. To use wrapper IDE should:
- create a wrapper in file system
- configure project for using the wrapper
- build project with the wrapper
- and if user need a dynamic support of "build analyzer", use the wrapper in development cycle prebuild-clean-build
2. The same problem on Windows. Proposed tool collection wrappers does not work on Windows. Wrappers should be an executable (PE) files with 32 and 64 bitness.

- TAB symbol cannot be safely printed in output. Reader should be prepared to understand "\t" string instead of TAB symbol
Comment 9 Alexander Simon 2016-05-20 10:35:22 UTC
IDE creates tool collection wrapper in a project metadata in the folder nbproject/private/tools/<hostname>/<real tool collection name>
Folder contains scripts or binary files with names of real C and C++ compilers.
Created wrappers are used in pre-build, clean and build actions.
