Full Text Bug Listing

sys-devel/gcc-4.3.2 was released on 2008-08-29.

It seems to be working with old 4.3.1-r1 ebuild.

I just had to copy patch files in distfiles from 4.3.1 version names into new
versions and then to modify gcc-4.3.2.patches-1.1.tar.bz2 : untar, delete last
patch ("74_all_sh-pr24836.patch") and tar bzip2 it again.

It seems to be working fine. At the end of ebuild ( gcc-config phase) I'v got
some message that it it seems that compiler doesn't use GCC_SPECS variable or
somesuch, but it seems that gcc-config was initially conffused as it reported
"invalid profile". After flipping it back and forth it worked fine...

is not the 74_all_sh-pr24836.patch that needed to be deleted.
it is 75_all_gcc43-pr36533.patch
http://gcc.gnu.org/bugzilla/buglist.cgi?bug_status=RESOLVED&resolution=FIXED&target_milestone=4.3.2

I have 2 problems.
They've appeared when I did this way:
1. I repacked patch and copied ebuild from gcc-4.3.1-r1
2. I emerged gcc-4.3.2
3. I unemerged old gcc-4.1.xxx

Problems:
1. When I imported python module lapack
#from numpy.linalg import lapack_lite
I have:
#ImportError: libgfortran.so.1: cannot open shared object file: No such file or
directory
Then:
#ld lapack_lite.so
ld: warning: libgfortran.so.1, needed by /usr/lib/liblapack.so.0, not found
(try
 using -rpath or -rpath-link)
ld: warning: cannot find entry symbol _start; not setting start address

/usr/lib/liblapack.so.0: undefined reference to `_gfortran_pow_r8_i4'
/usr/lib/liblapack.so.0: undefined reference to `_gfortran_pow_r4_i4'

2. When I build cross-compile toolchain arm-unknown-linux-gnueabi
#crossdev --target arm-unknown-linux-gnueabi
I have:
#In file included from <stdin>:1:

I am no guru, but it seems to me that your problem has nothing to do with
gcc-4.3.2.

You probably have to reemerge package that was compiled with gcc-4.1* and so it
was linked against gcc's libgfortran.so.

I have a couple of gcc's and those that have fortran frontend, have
coresponding libs:

find /usr/lib64 -name "libgfortran*"

So, have you reemerged lapack ?

I reemerged lapack-reference. Lapack_lite work fine. Thanks! Now I have 1
problem. :)

Is there any special reason this has not hit the tree yet, or is it just that
no dev has had the time to do the testing and bumping?

 My guess is the later.

I have emerged much of the system with very aggressive CFLAGS and it has worked
for the most part, except a few apps where gcc segfaulted.
( CFLAGS=-march=barcelona -O3 -pipe -combine -fweb -ftracer -fsee
-ftree-loop-linear -ftree-loop-im -ftree-loop-ivcanon -fivopts -ftree-vectorize
-fprefetch-loop-arrays -mfpmath=sse,387 -funswitch-loops -fgcse-lm -fgcse-sm
-fgcse-after-reload -fipa-pta -fipa-cp -ftree-loop-linear -ftree-loop-im
-fvect-cost-model -ftree-vectorize )


With sane CFLAGS it seems to be working totally O.K.

I wtite this on machine with world emerged on with gcc-4.3.2 with
CFLAGS="-march=barcelona -O2 -pipe.


It works without apparent issue.

My guess is that SpankY is busy with other stuff. Just be patient, he won't
forget us ;)

Created an attachment (id=166043) [details]
gcc-4.3.1-r1-to-4.3.2.ebuild.diff

I got impatient and bumped the ebuild in my local overlay. Thanks to the huge
toolchain.eclass, the changes to the ebuild are quite minimal. But I still
hope, this gcc version gets some love by the toolchain maintainers soon ;)

This patch worked for me.  Every package on my system built without an issue. 

gcc -v
Using built-in specs.

Finally I had the time to run "emerge -e system && emerge -e world" with
gcc-4.3.2 on my machine.
System built without any problems and world only had three failing packages but
none of those errors were gcc-related.

Finally got around to committing the bumped ebuild with the new patchset. 
Please test and open any bugs if there are problems with it.

It works for me. Just emerged it, and recompiled glibc with it. 
Everything seems fine.
