----------------

Here notice namely the "install:" line, where the tail seems to be somehow
strangely duplicated, creating a nonexisting directory. It should be
"/usr/local/opt/MDL/opt/gcc-4.4/lib64/gcc/x86_64-pc-linux-gnu/4.4.0/", instead
the last two subdirs are duplicated (even without a splitting slash) at the end
creating the nonsense that is there.

This results in a lot of trouble. The compiler is then for instance unable to
find any of its internal includes, such as when trying to compile the following
example:

----x.cc--------------
#include <streambuf>
int main () {return 0;}
---------------------

Then "g++ x.cc -o x -v" produces the following:

---------------------
$ gcc x.cc -o x -v

Moreover, I think that the "../../" that also appears in some of the search
paths that are found as nonexistent should actually be "../../../".

Is there a reason why you use --enable-version-specific-runtime-libs ?

------- Comment #3 from martin dot drab at fjfi dot cvut dot cz  2008-05-22 21:51 -------
Is using --enable-version-specific-runtime-libs the problem?
Should it not be used? I use it because from time to time I have more than one
version installed at the same time. Do you say that it should not be used? I'll
try if it gets any better that way, then.

------- Comment #4 from martin dot drab at fjfi dot cvut dot cz  2008-05-23 00:40 -------
OK, tried current snapshot without the --enable-version-specific-runtime-libs
and no change. :-( So, that was probably not the problem.

[Bug middle-end/36213] Wrong search path generation

[pinskia at gcc dot gnu dot org]

------- Comment #5 from pinskia at gcc dot gnu dot org  2008-05-23 00:44 -------
Is there a reason why you are supplying all these weird configure options?

--exec-prefix=/usr/local/opt/MDL/opt/gcc-4.4 --sysconfdir=/etc
--libdir=/usr/local/opt/MDL/opt/gcc-4.4/lib64
--libexecdir=/usr/local/opt/MDL/opt/gcc-4.4/libexec64
--includedir=/usr/local/opt/MDL/opt/gcc-4.4/include
--infodir=/usr/local/opt/MDL/opt/gcc-4.4/share/info
--mandir=/usr/local/opt/MDL/opt/gcc-4.4/share/man 

The default for them will be based on the prefix.

Thanks,
Andrew Pinski

------- Comment #6 from martin dot drab at fjfi dot cvut dot cz  2008-05-23 00:49 -------
One more thing I've forgotten to mention is that (no matter if the
--enable-version-specific-runtime-libs is there or not) files limits.h and
syslimits.h are not generated into the internal "include" directory of the gcc,
but into the "include-fixed" directory, where, however, gcc can't find them. So
I had to create a symlink there, otherwise lots of stuff can't be compiled.
Though, I don't know if it is due to the badly generated paths. Maybe if they
were correct, gcc would have found the files even in that directory. So, that
may actually be OK.

Just to make sure they are where I want them to be. Basically most of them need
not be there, because they are what they are based on the prefix. That's right.
I just want to make sure, that the 64-bit library and libexec dirs get the *64
at the end (because I use it all over the system that way - Gentoo ;) and I
really hate it when info and man is not generated into the share subdir. Though
I admit, that since I install the entire gcc into a separate directory, i can
probably leave this on automatic based on prefix. That's right.

But I have been using the prefixes like these for ages and it used to work with
4.3 and older versions just fine.

[Bug middle-end/36213] Wrong search path generation

[martin dot drab at fjfi dot cvut dot cz]

------- Comment #9 from martin dot drab at fjfi dot cvut dot cz  2008-05-23 11:09 -------
OK, so I tried to compile with autogenerated paths just from the prefix, and
with the --enable-version-specific-runtime-libs option. The path no longer
seems corrupted. It searches all its internal include directories properly now.

So, that rises a question. Why there is the posibility to explicitly set all
the various directories (like --libdir, --libexecdir, --includedir, ...etc.),
when if you set them gcc can't handle it?

And there is also one more problem with the paths. I tried the simple example
with the

----x.cc--------------
#include <streambuf>
int main () {return 0;}
---------------------

as in the initial report. See what it produces below. Though includes are found
fine, this time it is the libgcc_s, that is not found. For some reason, it is
generated to an entirely different directory than all other libraries of the
gcc. While most of the libraries are generated into the
<prefix>/lib/gcc/<arch>/<version>/ (for 64-bit libs) and
<prefix>/lib/gcc/<arch>/<version>/32 (for 32-bit libs), the libgcc_s is for
some unknown reason generated into the <prefix>/lib/gcc/<arch>/lib64/ and
<prefix>/lib/gcc/<arch>/lib32/ directories respectively, and gcc can't find
them since it does not pass these paths to the linker. Why is that?

Alright, and I think I know what causes the rest of the path problem. The
GCC_EXEC_PREFIX environment variable has to lead to the .../lib/gcc/ and not
the .../lib/gcc/x86_64-pc-linux-gnu/4.4.0 and IT HAS TO END WITH A SLASH (!!),
otherwise it is composed incorrectly by the gcc. Now everything seems to be
working just fine. :-) (Except for the problem in PR32415 of course.)
