Bugzilla Bug 128557

dev-libs/expat-2.0.0 provides /usr/lib/libexpat.so.1 but gettext doesn't find
it.

unaffiliated portage # strings $(which xgettext) | grep expat
libexpat.so.0
Language "glade" is not supported. %s relies on expat.
This version was built without expat.

Testcase ebuild of BMPx SVN HEAD, with USE="nls"

Problem goes away, when libexpat.so.1.5.0 is symlinked to libexpat.so.0

in gettext-0.14.5/gettext-tools/src/x-glade.c

Make gettext look just .so instead of .so.0 as both versions of expat provides
it.

should maybe be:
void *handle = dlopen ("libexpat.so.0", RTLD_LAZY);
if (handle == NULL)
    void *handle = dlopen ("libexpat.so.1", RTLD_LAZY);

i'll bug upstream

Created an attachment (id=83943) [edit]
gettext-expat-2.patch

please give this patch a test from upstream

Created an attachment (id=83977) [edit]
5454-gettext-0.14.5-r1.log, building with new patch. OK.

Moment, building the program that uses gettext I encountered this problem in
first place..

Seems to be working.

Damn, it didn't work afterall! Sorry about the previous post, builded wrong
version by an accident.

drac@unaffiliated ~ $ grep MAJOR /usr/include/expat.h
#define XML_MAJOR_VERSION 2

It's there.. but still it doesn't pick it up. This is also strange:

drac@unaffiliated ~ $ strings `which xgettext` | grep -i expat
libexpat.so.0
Language "glade" is not supported. %s relies on expat.
This version was built without expat.

no strings of libexpat.so.1..

BMPx now compiles, but still.. problem is still there. gettext doesn't use
expat 2.x at all, because of hardcoding. See comment 3.

spanky, can you version bump gettext to 0.15, it was relesed yesterday and has
code for expat 2.0.

and close this bug.

0.15 now in cvs
