Bugzilla Bug 62124

When I emerge mpqc-2.2.2 on my ppc64 system (Dual G5 Mac) and run the binary:

ClassDesc::load_class looking for "./classes"
ClassDesc::load_class("CLKS"): load failed
Either "CLKS" is an invalid class name or the code
for "CLKS" was not linked into the executable.
Segmentation fault
....

When I add --enable-shared to configure in mpqc-2.2.2.ebuild and emerge
again - the binary work as expected.


Reproducible: Always
Steps to Reproduce:
1.emerge mpqc
2.mpqc test.in
3.

Actual Results:  
mpqc test.in
[cut cut]
ClassDesc::load_class looking for "./classes"
ClassDesc::load_class("CLKS"): load failed
Either "CLKS" is an invalid class name or the code
for "CLKS" was not linked into the executable.

Expected Results:  
mpqc test.in

gcc-3.4.1; binutils-2.15.90.0.3-r3; CFLAGS="-O2";

moving this over to ppc64, where it looks like it belongs.

can you please provide that test.in file.

Also mpqc-2.2.3 has been released some while ago, but is not yet in portage. Could you try this version?

as I don't have a test case and the user doesn't submit the test.in, I cannot
test this. Please reopen if a test case is provided.

boris provided me a test4.in. thanks!

test4.in

The test4.in for testing. We'll have to wait for 2.2.3 to get into portage
untill we can test that. maybe it is fixed.. I just don't want to spend time on
a bug, which might be already fixed in a newer version. ;-)

how about adding IUSE="static" and build the package shared without that set.
Something like: if ! ( use static && use ppc64 ) then ...

mpqc-ebuild.patch

this is a diff which applies against mpqc-2.2.2-r1.ebuild and makes use of
--enable-shared. now test4.in works for me.

basicly the solution was given in the bug report itself.. thx! ;-)

I finaly could run `mpqc test4.in` with success! 
 
I've added a patch to the ebuild so that --enable-shared is used on ppc64.  
  
sorry, that this took so so so long.. 
 
also added ~ppc64 of cause.
