[Gluster-devel] Embedding debug symbols in glusterfsd

[Lluís Pàmies i Juárez]

Jeff,

Unfortunately, even with the "--enable-debug=yes", "make install" does not
include the debugging symbols for neither libraries (xlators) nor binaries.
I realized that the problem is with the "install" command that strips both
binaries and libraries even when the flag "-s" is not set. At least this is
the behavior in my Arch Linux setting.

I found a solution which is to define my own PKGBUILD file (to build arch
linux installation packages), with "options=(debug !stripe)". Somehow the
"!stripe" must be setting some environment variable to force the "install"
command to not stripe things. After installing the generated package with
"pacman -U" I have binaries and libraries with their own debugging symbols
;). In your case you might be able to do the same with the rpmbuild [1].

Thank you,
