[Automake] How to get debug symbols in the executable?

[Marcelo Zimbres]

Hi,

I am having some trouble to debug programs built from autotools. I am
following the steps:

$ ./configure CXXFLAGS="-g -O0"
$ make
$ libtool --mode=execute gdb --arg ./swat_find arg_list

When I run the last line, I get the error message:

Reading symbols from
/home/marcelo/Public/swat/debug/.libs/lt-swat_find...(no debugging symbols
found)...done.

Why there are no symbols? The output of make shows the flags have been
passed to gcc, for example:

libtool: compile:  g++ -DHAVE_CONFIG_H -I. -I.. -I/usr/local/include/root
-I/usr/local/include/root -I -I -g -O0 -MT libswat_la-TDKernel.lo -MD -MP
-MF .deps/libswat_la-TDKernel.Tpo -c ../TDKernel.cxx -o
libswat_la-TDKernel.o >/dev/null 2>&1

I couldn't also find the -s option which would discard the symbols. Can
someone help me?

Thanks,
Marcelo

ps. I am using automake version 1.11.3
