[Bug middle-end/36213] Wrong search path generation
--- Comment #11 from martin dot drab at fjfi dot cvut dot cz 2008-05-23 16:05 --- 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.) -- martin dot drab at fjfi dot cvut dot cz changed: What|Removed |Added Status|UNCONFIRMED |RESOLVED Resolution||INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36213
[Bug middle-end/36213] Wrong search path generation
--- 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
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
/lib/gcc/// (for 64-bit libs) and
/lib/gcc///32 (for 32-bit libs), the libgcc_s is for
some unknown reason generated into the /lib/gcc//lib64/ and
/lib/gcc//lib32/ directories respectively, and gcc can't find
them since it does not pass these paths to the linker. Why is that?

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.

[Bug middle-end/36213] Wrong search path generation
--- 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. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36213

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
int main () {return 0;}
-
Then "g++ x.cc -o x -v" produces the following:
-
$ gcc x.cc -o x -v

[Bug tree-optimization/36066] [4.4 Regression] ICE with -O1 -finline-small-functions -ftree-vrp -funsafe-loop-optimizations
--- Comment #5 from martin dot drab at fjfi dot cvut dot cz 2008-04-27 22:54 --- And the test cases also fail with -O1 -finline-small-functions -ftree-vrp -m32 so if you compile it for 32-bit target, naither the -funsafe-loop-optimizations nor the -fprefetch-loop-arrays needs to be specified. Haven't tested it on a native 32-bit host, so, hard to say whether it would ICE there as well, just like this. However, natively on a 64-bit host with just "-O1 -finline-small-functions -ftree-vrp" it works without an ICE. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36066
