Is there a way to install debugging information for gcc, as one can for glibc and other packages?
I'm trying to test a change to Knot 3.0.0 and have found that gcc takes forever to finish linking (and usually crashes from running out of memory) when building the package using "guix build knot". Meanwhile, if I build the source "manually", from within "guix environment --pure knot", everything works fine. I'd like to diagnose this but connecting to the running gcc instance using gdb doesn't reveal much without gcc's debugging information available. I've tried "guix install [email protected]:debug" but that installs debugging information for only glibc. I could edit gnu/packages/gcc.scm to set the "stripped?" variable to false and rebuild gcc so its debugging symbols are preserved, but then it's not clear how to install them. It seems I can build and install gcc itself with guix package --install-from-expression='(@ (gnu packages gcc) gcc-7)' but what I really want is guix package --install-from-expression='(@ (gnu packages gcc) (list gcc-7 "debug"))' This fails with a syntax error, however, and I see the documentation for "guix package" says Note that this option installs the first output of the specified package, which may be insufficient when needing a specific output of a multiple-output package. Is there a trick to making this work? -- Simon South [email protected]
