emerge libjsw fails (as does make from tarball)

Hi.

I'm trying to emerge libjsw and it keeps failing on string.cpp

it dies with this error message:

Building library "libjsw.so.1.5.5"...
Compiling module axisio.o

   char*)' throws different exceptions
string.cpp:31: error: than previous declaration `char* strcasestr(const char*,
   const char*) throw ()'
make: *** [string.o] Error 1

I also tried unpacking the tarball and using make to compile; no effect.

I've searched quite a bit and haven't been able to find anything similar

Thanks in advance for any help

-Nate

That doesn't happen to me with either libjsw 1.5.5 or 1.5.4. I'm using gcc 3.4.3-r1. The code should not generate that error under any circumstances anyway (I've looked at it), so it looks like a bug in g++.
You could try applying the following patch:

Thanks. It appears to be a bug in g++ 3.3.4. I simply used gcc-config to switch to 3.4.2 and it emerged fine.

Is this something that would be worth making a bug report about? (I suppose I'll see if I can reproduce it on any of my other boxes)

Sure it is, and it's very commendable of you to contribute feedback!
If you open a new bug in Bugzilla (provided that there isn't one already, might be worth searching), please make sure to assign the bug to vapier@gentoo.org (he's the maintainer).

Just for the record, I have the same problems with jibjsw 1.5.5 and gcc 3.3.4.

yay, me too! think we could get a link to that bug?

And the solution is ??

I tried to apply the patch, but I have always an error :

string.cpp:31: error: declaration of `char* strcasestr(const char*, const
char*)' throws different exceptions
../include/string.h:46: error: than previous declaration `char*

guess i didn't find a solution, i just haven't merged it yet. maybe the new one could be user masked till its fixed?

canek · Post by **canek** » Sun Mar 20, 2005 12:40 am

1.5.5 is the last version; there is no new version. I put

Code: Select all

>=media-libs/libjsw-1.5.4

in /etc/portacke/package.mask, so emerge -uDv world doesn't bother me trying to update libjsw; but the problem is there, even in the 1.5.4 version.

considering the fact that the only application my joypad seems to work in 100% is jscalibrator, the failure of libjsw to compile is a devastating blow to me.

more seriously, ive noticed that joy2key is also not compiling. i wonder if the two are related?

i've got the same problem

On this bug report there is an ebuild that works from thorsten.

Lars · Post by **Lars** » Sat Apr 09, 2005 6:43 pm

My resolution

Code: Select all

ebuild /usr/portage/media-libs/libjsw/libjsw-1.5.5.ebuild unpack

goto it's unpacked directory /var/tmp/portage/libjsw... find all what has something todo with 'strcasestr' and remark it, don't forget, in *.h files use /* ... */ and in *.cpp files '// ...' is ok.

Code: Select all

ebuild /usr/portage/media-libs/libjsw/libjsw-1.5.5.ebuild compile

Code: Select all

ebuild /usr/portage/media-libs/libjsw/libjsw-1.5.5.ebuild install

Code: Select all

ebuild /usr/portage/media-libs/libjsw/libjsw-1.5.5.ebuild postinst

Code: Select all

ebuild /usr/portage/media-libs/libjsw/libjsw-1.5.5.ebuild qmerge

Code: Select all

ebuild /usr/portage/media-libs/libjsw/libjsw-1.5.5.ebuild merge

Maybe there are some ebuilds obsolete but shit happens, it works for me.

The easiest resolution to this problem from what I can tell, is to use gcc-config to switch to the 3.4.3 profile.
2005.0 makes use of it anyway.

Code: Select all

# gcc-config i686-pc-linux-gnu-3.4.3-20050110 && source /etc/profile
