[SOLVED] Add GCC debug flags

I need to debug a program called tenace [1] which I maintain in AUR [2]. My question is how do I change the FLAGS to add debug (gdb) capabilities. The program is written in C.
This is the current PKGBUILD [3]

gdb reads:

Reading symbols from tenace...(no debugging symbols found)...done.

Please be a little verbose in your answer I don't know what flag to add not don't I know where I would add flags. It seems to me I want to change this line:

./configure --prefix=/usr LDFLAGS=-lm

but please correct me if I'm wrong.

[2] https://aur.archlinux.org/packages/tenace/

Re: [SOLVED] Add GCC debug flags

It looks like the source defaults to including the flag for building anyways.  Just add the !strip option to the PKGBUILD to prevent makepkg from stripping the symbols.

Re: [SOLVED] Add GCC debug flags

Thanks,

Adding

options=('!strip')

does what I want it to do. Running gdb gives a backtrace with the function where the error occurs. Those function-names were previously not available.

Marking as SOLVED
