Experimental Physics and Industrial Control System
Hi All,
I have noticed over the years that the EPICS build system isn't particularly helpful when using an IDE because it doesn't generate full source file paths on the compiler command line, and instead subdirectory dependent relative paths are used. This seems to cause gcc to produce also relative source file paths in its compiler messages which can interfere with clicking on the error message and vectoring the focus to the appropriate source file in the IDE. It seems that gcc could easily provide an option to force generation of full (not relative) source file paths in its output no matter what the format is of its input file paths might be, but AFAIKT, it doesn't.
However, maybe this post suggests a solution that could be applied generically within the internals of the EPICS build system to produce full path names in the compilers input while continuing to navigate the build system with relative paths.
http://gcc.gnu.org/ml/gcc-help/2008-03/msg00084.html
This would result in rather more verbose build message output, but would improve productivity when using an IDE from my perspective. I suppose that we might also provide a configure option which determines the type of compiler file path output that gets generated depending on a particular user's needs, if that was important.
Comments?
