libiberty problem in ddd

[Martin Opel]

Hi,

I'm trying to compile ddd 3.3.8 on a system without installed libiberty.a.
It is a GNU/Linux system (Crux Linux) with a 2.4.21 vanilla kernel, a
glibc-2.3.2 and gcc-3.2.3.

There are two bugs:

1. CFLAGS Bug
=============
If the CFLAGS or CXXFLAGS contains spaces like CFLAGS="-O2
-march=i686", then the configure of the libiberty subdirectory fails,
because the configure arguments are wrong:

>configure: configuring in libiberty
>configure: running /bin/sh './configure' --prefix=/usr  '--prefix=/usr'
>'CFLAGS=-O2 -march=i586 -pipe' 'CXXFLAGS=-O2 -march=i586 -pipe'
>--cache-file=/dev/null --srcdir=.
>configure: warning: CFLAGS=-O2 -march=i586 -pipe: invalid host type
>configure: warning: CXXFLAGS=-O2 -march=i586 -pipe: invalid host type
>configure: error: can only configure for one host and one target at a time
>configure: error: /bin/sh './configure' failed for libiberty
>=======> ERROR: Building '/usr/ports/contrib/ddd/ddd#3.3.8-1.pkg.tar.gz'

I inserted a sed call into the configure script to solve this problem:
ac_sub_configure_args=
  `echo $ac_sub_configure_args | sed -e "s,'[^']*',,g"`


2. missing libiberty header files
=================================
there are some missing header files in the include subdirectory, which are
required by the included libiberty: xregex.h, xregex2.h, safe-ctype.h,...
I solved this only by taking the libiberty/include dirs of a current
gcc-3.2.2 archive.


Bye
Martin
