cd objdir; make install
We strongly recommend to install into a target directory where there is no previous version of GCC present.
That step completes the installation of GCC; user level binaries can
be found in prefix/bin where prefix is the value you
specified with the --prefix to configure (or /usr/local
by default). (If you specified --bindir, that directory will
be used instead; otherwise, if you specified --exec-prefix,
exec-prefix/bin will be used.) Headers for the C++ and
Java libraries are installed in prefix/include; libraries
in libdir (normally prefix/lib); internal
parts of the compiler in libdir/gcc-lib; documentation in
info format in infodir (normally prefix/info).
When installing cross-compilers, GCC's executables
are not only installed into bindir, that
is, exec-prefix/bin, but additionally into
exec-prefix/target-alias/bin, if that directory
exists. Typically, such tooldirs hold target-specific
binutils, including assembler and linker.
Installation into a temporary staging area or into a chroot
jail can be achieved with the command
make DESTDIR=path-to-rootdir install
where path-to-rootdir is the absolute path of
a directory relative to which all installation paths will be
interpreted. Note that the directory specified by DESTDIR
need not exist yet; it will be created if necessary.
There is a subtle point with tooldirs and DESTDIR:
If you relocate a cross-compiler installation with
e.g. DESTDIR=rootdir, then the directory
rootdir/exec-prefix/target-alias/bin will
be filled with duplicated GCC executables only if it already exists,
it will not be created otherwise. This is regarded as a feature,
not as a bug, because it gives slightly more control to the packagers
using the DESTDIR feature.
If you built a released version of GCC using make bootstrap then please
quickly review the build status page for your release, available from
http://gcc.gnu.org/buildstat.html.
If your system is not listed for the version of GCC that you built,
send a note to
gcc@gcc.gnu.org indicating
that you successfully built and installed GCC.
Include the following information:
/config.guess. Do not send us
that file itself, just the one-line output from running it.
gcc -v for your newly installed gcc.
This tells us which version of GCC you built and the options you passed to
configure.
gcc -v, but if you downloaded the
"core" compiler plus additional front ends then it isn't apparent
which ones you built unless you tell us about it.
/etc/issue.
uname --version
or uname -a.
rpm -q glibc to get the glibc version,
and on systems like Debian and Progeny use dpkg -l libc6.
We'd also like to know if the host/target specific installation notes didn't include your host/target information or if that information is incomplete or out of date. Send a note to gcc@gcc.gnu.org telling us how the information should be changed.
If you find a bug, please report it following our bug reporting guidelines.
If you want to print the GCC manuals, do cd objdir; make
dvi. You will need to have texi2dvi (version at least 4.2)
and TeX installed. This creates a number of .dvi files in
subdirectories of objdir; these may be converted for
printing with programs such as dvips. You can also
buy printed manuals from the Free Software Foundation, though such manuals may not be for the most
recent version of GCC.
