[Bug driver/19856] GCC_EXEC_PREFIX used wrong
--- Additional Comments From bryanh at giraffe-data dot com 2005-02-09 17:06 --- Created an attachment (id=8157) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=8157&action=view) strace of failure to find cc1 In this run, PREFIX is /home/bryanh/gcc . GCC_EXEC_PREFIX is /tmp2/gcc-3.4.3/lib/gcc// . /tmp2 is a symlink to /mp/hdb2 . Gcc, in the form created by 'make install', is installed in /tmp2/gcc-3.4.3 -- i.e. 'make install' created the tree at /home/bryanh/gcc and I moved it to /tmp2/gcc-3.4.3. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19856

--- Additional Comments From pinskia at gcc dot gnu dot org 2005-02-09 19:07 --- I think this related to PR 14435. But reading the docs (there is a section in there which is useful to read): 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 /usr/local/lib/gcc (more precisely, with the value of GCC_INCLUDE_DIR), GCC tries replacing that beginning with the specified prefix to produce an alternate directory name. Thus, with -Bfoo/, GCC will search foo/bar where it would normally search /usr/local/lib/bar. These alternate directories are searched first; the standard directories come next. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19856

--- Additional Comments From bryanh at giraffe-data dot com 2005-02-09 19:43 --- Subject: Re: GCC_EXEC_PREFIX used wrong I don't see the relevance of that paragraph to either of the problem reports, since there is no search for header files involved. I don't know anything about the Gcc bug fixing process, but I see that PR 14435 is 11 months old. Has anything been changed because of it? Will it be? If code or doc needs to be written, I'd be happy to do it, but if someone else has to figure out what GCC_EXEC_PREFIX should do, that would be premature. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19856

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=19856 --- Comment #5 from Bryan Henderson --- A quick check of the latest manual shows the same description, and a quick strace of GCC 6.3 shows the same behavior, so my guess is no one has touched this area.
