Environment FreeBSD 2.2.5, binutils 2.9 and gdb 4.17
When building libiberty as part of either binutils 2.9 or gdb 4.17 with
a FreeBSD 2.x host, gnu make (3.76.1) successfully builds libiberty.a,
but reports a circular dependency. Running gnu make in the libiberty
directory after the library is successfully built gives:
pc0640% gmake
gmake[1]: Entering directory `/usr/users/jeremyp/src/binutils/libiberty'
gmake[1]: Circular vasprintf.o <- config.h dependency dropped.
gmake[1]: Leaving directory `/usr/users/jeremyp/src/binutils/libiberty'
pc0640%
The standard FreeBSD 2.2.5 make is unable to handle the circular
dependency and exits without building the library.
This problem does not exist on a Sun Solaris 2.x host and appears
to be related to the `EXTRA_OFILES=vasprintf.o' line in the
Makefile - it appears that the dependency handling for EXTRA_OFILES
is incorrect.
Relevant configuration files from binutils are:
------- binutils/config.status: --------------------------------
#!/bin/sh
# This file was generated automatically by configure. Do not edit.
# This directory was configured as follows:
/mnt/src/binutils-2.9/configure --host=i386-unknown-freebsd2.2.5 --target=m68k-unknown-coff --with-mmap --with-gnu-as --with-gnu-ld --enable-targets=i386-unknown-freebsd2.2.5,m68k-unknown-coff --disable-shared --norecursion
#
------- binutils/config.cache: --------------------------------
# This file is a shell script that caches the results of configure
# tests run on this system so they can be shared between configure
# scripts and configure runs. It is not useful on other systems.
# If it contains results you don't want to keep, you may remove or edit it.
#
# By default, configure uses ./config.cache as the cache file,
# creating it if it does not exist already. You can give configure
# the --cache-file=FILE option to use a different cache file; that is
# what configure does when it calls configure scripts in
# subdirectories, so they share the cache.
# Giving --cache-file=/dev/null disables caching, for debugging configure.
# config.status only pays attention to the cache file if you give it the
# --recheck option to rerun configure.
