particularly useful if you intend to use several versions of GCC in

@command{/usr/ccs/bin/as} into
-@command{/usr/local/lib/gcc-lib/sparc-sun-solaris2.7/3.1/as},

adjusting the latter name to fit your local conventions and software
version numbers.
For each subprogram to be run, the compiler driver first tries the
@option{-B} prefix, if any. If that name is not found, or if @option{-B}
was not specified, the driver tries two standard prefixes, which are
-@file{/usr/lib/gcc/} and @file{/usr/local/lib/gcc-lib/}. If neither of
+@file{/usr/lib/gcc/} and @file{/usr/local/lib/gcc/}. If neither of
those results in a file name that is found, the unmodified program
name is searched for using the directories specified in your
@env{PATH} environment variable.
tries looking in the usual places for the subprogram.
The default value of @env{GCC_EXEC_PREFIX} is
-@file{@var{prefix}/lib/gcc-lib/} where @var{prefix} is the value
+@file{@var{prefix}/lib/gcc/} where @var{prefix} is the value
of @code{prefix} when you ran the @file{configure} script.
Other prefixes specified with @option{-B} take precedence over this prefix.
In addition, the prefix is used in an unusual way in finding the
directories to search for header files. For each of the standard
-directories whose name normally begins with @samp{/usr/local/lib/gcc-lib}
+directories whose name normally begins with @samp{/usr/local/lib/gcc}
(more precisely, with the value of @env{GCC_INCLUDE_DIR}), GCC tries
replacing that beginning with the specified prefix to produce an
alternate directory name. Thus, with @option{-Bfoo/}, GCC will search
projects / thirdparty / gcc.git / commitdiff
