gcc-3.0.1 fails to build

[nisse at lysator dot liu dot se (Niels Möller)]

I tried building gcc-3.0.1 with the following procedure:

  ./configure && make bootstrap

This was on a sparc-unknown-linux-gnu box (a sparcstation 4 running
debian).

Generation of some include file in libstdc++ failed like this:

  make[4]: Entering directory `/home/src/gcc-3.0.1/sparc-unknown-linux-gnu/libstdc++-v3/include'
  echo `date` > stamp-sparc-unknown-linux-gnu

      < /usr/local/src/gcc-3.0.1/sparc-unknown-linux-gnu/libstdc++-v3/../gcc/gthr.h > sparc-unknown-linux-gnu/bits/gthr.h
  /bin/sh: /usr/local/src/gcc-3.0.1/sparc-unknown-linux-gnu/libstdc++-v3/../gcc/gthr.h: No such file or directory
  make[4]: *** [sparc-unknown-linux-gnu/bits/gthr.h] Error 1
  make[4]: Leaving directory `/home/src/gcc-3.0.1/sparc-unknown-linux-gnu/libstdc++-v3/include'

libstdc++/include/Makefile.am contains three rules of the form

  ${thread_builddir}/gthr.h:
  	  sed -e '/^#/s/\(${uppercase}${uppercase}*\)/_GLIBCPP_\1/g' \
  	      -e 's,^#include "\(.*\)",#include <bits/\1>,g' \
  	      < ${glibcpp_srcdir}/../gcc/gthr.h > $@
  
  ${thread_builddir}/gthr-single.h:
  	  sed -e 's/\(UNUSED\)/_GLIBCPP_\1/g' \
  	      -e 's/\(GCC${uppercase}*_H\)/_GLIBCPP_\1/g' \
  	      < ${glibcpp_srcdir}/../gcc/gthr-single.h > $@
  
  ${thread_builddir}/gthr-default.h:
  	  sed -e 's/\(UNUSED\)/_GLIBCPP_\1/g' \
  	      -e 's/\(GCC${uppercase}*_H\)/_GLIBCPP_\1/g' \
  	      -e 's/\(${uppercase}*WEAK\)/_GLIBCPP_\1/g' \
  	      < ${glibcpp_srcdir}/../gcc/${glibcpp_thread_h} > $@

It seems it is the referrence ${glibcpp_srcdir}/../gcc/ that is
broken.

The Makefile sets these variables:

  glibcpp_srcdir = /usr/local/src/gcc-3.0.1/sparc-unknown-linux-gnu/libstdc++-v3
  glibcpp_builddir = /usr/local/src/gcc-3.0.1/sparc-unknown-linux-gnu/libstdc++-v3

To me, it seems that the forst line should be

  glibcpp_srcdir = /usr/local/src/gcc-3.0.1/libstdc++-v3

Next, I'll try building in a separate directory to see if that works
better.

Ah, and one more thing: I couldn't find any information about 3.0.1 in
the NEWS file.
