README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. Check the INSTALL directory for detailed configuration and installation instructions. Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
This is a libg++ addon for libstdc++ 2.8.1.1 and current egcs releases
(i.e. egcs-1.1). It is needed only if your applications depend on
libg++ and you cannot easily remove the dependency on libg++.
The standalone libg++ is no longer needed. Note that this package
is no longer being maintained.
To install, move all the files in this directory into the directory
where you unpacked libstdc++ version 2.8.1.1 (or unpacked version
2.8.0 and applied the diff to convert it to version 2.8.1.1) or egcs-1.x.
Then you can configure/build/check/install libstdc++ or egcs normally.
Now it will include libg++.
libg++-2.8.x is collaborative work of various people, most notably
H.J. Lu and Manfred Hollstein; because libg++ is no longer being actively
maintained you should not start new C++ projects using libg++.
Changes from libg++-2.8.1.1a:
- Updated g++ FAQ.
- Merge with current Cygnus development version.
- DejaGNU based testsuite added (thanks to Bob Manson).
- Fix relative path for multilib
- Fix relative path for cross-compile.
- Use relative path for symbolic links.
- Include <termcap.h> in etc/lf/screen.cc for Linux.
- Add the interface support for the library names.
- Handle --enable-version-specific-runtime-libs.
- Fix some parallel build bugs.
- A librx bug fix.
- gperf is removed from libg++. The stand-alone gperf is available at
<ftp://ftp.gnu.org/pub/gnu>
The current version, as of May 5, 1998, is gperf 2.7.
The libg++ and librx have been tested with
- egcs 1.0.3 and pre-1.1 on linux/x86/libc 5, linux/x86/glibc 2.1 and
linux/alpha/glibc 2.0.7, hppa1.1-hp-hpux10.20, m68k-motorola-sysv,
m88k-motorola-sysv3, sparc-sun-solaris2.5.1, sparc-sun-solaris2.6
and sparc-sun-sunos4.1.4.
- gcc 2.8.1 and libstdc++ 2.8.1.1 on linux/x86/libc 5 and
linux/x86/glibc 2.0.7, hppa1.1-hp-hpux10.20, m68k-motorola-sysv,
m88k-motorola-sysv3, sparc-sun-solaris2.5.1, sparc-sun-solaris2.6
and sparc-sun-sunos4.1.4.
It is available at
ftp://ftp.gnu.org/pub/gnu/libg++-2.8.1.2.tar.gz
A patch for libg++ 2.8.1.1a is also available at
ftp://ftp.gnu.org/pub/gnu/libg++-2.8.1.1a-2.8.1.2.diff.gz
Potential problems with libstdc++ 2.8.1.1:
1. Since gcc 2.8.1 is installed under /usr on Linux/GNU by default,
you need to explicitly pass `--prefix=/usr' to the configure
command for libstdc++; change "/usr" to what's appropriate on
your system. Otherwise incorrect header files and libraries
may be used.
You also need to check the toplevel configure.in and configure to see
if the complete patch enclosed here is already applied (only egcs-1.0.x
releases do not include it already). If not, please do
$ patch -p0 < README.libg++
Then you can configure/build/check/install egcs normally. Now it
will include libg++.
