I'm having trouble walking through emacs source code in gdb. I think I'm missing debug symbols.
Following a suggestion from https://stackoverflow.com/a/4298982/2752242, I tried:
./configure CFLAGS="-ggdb3 -O0" CXXFLAGS="-ggdb3 -O0" LDFLAGS="-ggdb3" --with-gif=no --prefix=$HOME/local/apps/emacs-24.4/
But, that didn't work.
Are there instructions on compiling with debug symbols? Thanks!
I was able to get line numbers in gdb if I run the emacsclient binary that is produced by make that lives in emacs/lib-src. If I do make install and try to attach a debugger to the installed binary, no line numbers.
This is what worked for me:
$ CFLAGS="-ggdb3 -O0" CXXFLAGS="-ggdb3 -O0" LDFLAGS="-ggdb3" ./configure --enable-checking --with-gif=no --prefix=$HOME/local/apps/emacs-24.4/
$ make
$ gdb lib-src/emacsclient
This doesn't work:
$ CFLAGS="-ggdb3 -O0" CXXFLAGS="-ggdb3 -O0" LDFLAGS="-ggdb3" ./configure --enable-checking --with-gif=no --prefix=$HOME/local/apps/emacs-24.4/
$ make
$ make install
$ gdb $HOME/local/apps/emacs-24.4/bin/emacsclient
CFLAGS='-O0 -ggdb -g3' ./configure --enable-checking --enable-asserts. I'm not a pro, but I'm not sure you can give arguments toconfigurethe way you did it. Usually, those come before calling the program, and configure takes those from environment it's called with, but maybe it's something new...
