Re: How to get debug mode version of libstdc++ when compiling GCC

["Pit Cuppens" <pcuppens at gmx dot net>]

Dear all,

Thanks so far for your help. However, I still do not
manage to get debug support with GCC 3.3.2 and libstdc++.
(GCC 3.4 is not an option because a library I use does
not compile under it.)

I downloaded GCC 3.3.2, created the objdir and configured
GCC using

../gcc-3.3.2/configure --enable-languages=c++ \
   --enable-debug --enable-libstdcxx-debug 

make bootstrap and make install work fine, but
strangely, the directory include/c++/3.3.2/
(i.e., the place where the std library is copied
to by 'make install') does not contain any source
file containing '_GLIBCXX_DEBUG'. In other words,
the debug code is not installed.

Does anybody know where the problem lies?

Note that the command

  more sparc-sun-solaris2.9/libstdc++-v3/config.status

(within the objdir directory) really shows that
the configuration options '--enable-debug 
--enable-libstdcxx-debug' were passed to libstdc++:

#! /bin/sh
# Generated automatically by configure.
# Run this file to recreate the current configuration.
# This directory was configured as follows,
# on host pipi:
#
# /home/pc/gcc-3.3.2/libstdc++-v3/configure  --cache-file=../config.cache 
--host=sparc-sun-solaris2.9 --build=sparc-sun-solaris2.9 --enable-multilib 
--with-gcc-ve
rsion-trigger=/home/pc/gcc-3.3.2/gcc/version.c --prefix=/home/pc/software/
gcc-3.3.2/ --enable-languages=c++ --enable-debug --enable-libstdcxx-debug 
--srcdir=.
./../../gcc-3.3.2/libstdc++-v3 --with-target-subdir=sparc-sun-solaris2.9
#
# Compiler output produced by configure, useful for debugging
...

After this, I felt somewhat nervous and did a

   make CXXFLAGS='-g3 -O0' all

in the objdir, not really knowing what I do.
But still, the debug mode doesn't work.

Thanks in advance for any help!
Pit
