Bug 62124 – mpqc on ppc64: ClassDesc::load_class looking for "./classes"

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description boris 2004-08-29 10:43:58 UTC]

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.

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

[Comment 2 Markus Rothe (RETIRED) 2005-05-10 11:48:17 UTC]

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?

[Comment 3 Markus Rothe (RETIRED) 2005-05-12 23:07:21 UTC]

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. ;-)

[Comment 6 Markus Rothe (RETIRED) 2005-05-18 11:58:05 UTC]

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! ;-)

[Comment 8 Markus Rothe (RETIRED) 2005-06-11 09:24:45 UTC]

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.
