The same here.

The thing is worse than it seems at first look. The portage hasn't older
versions of the package. As a result, all dependencies are blocked.

Please, rise the issue priority.

I guess this wouldn't solve the problem. I guess the problem is xerces 2.8.x.
xalan supports officially only xerces 2.7.x, but on ~x86/~amd64 xerces 2.8.x is
installed.

I guess this wouldn't solve the problem. I guess the problem is xerces 2.8.x.
xalan supports officially xerces 2.7.x only, but on ~x86/~amd64 xerces 2.8.x is
installed.

I tried with dev-java/xerces-2.3.0-r3, but still the same error :-s

Moreover, no 2.7.x version is the portage tree.

You emerged the wrong package. It should be dev-libs/xerces-c, not
dev-java/xerces

My xalan-c was also broken (~amd64), and it works with
=dev-libs/xerces-c-2.7.0-r1 so I masked =dev-libs/xerces-c-2.8.0 for now.

Oops, sorry for my mistake. 

Solution confirmed, xalan-c has to be compiled with dev-libs/xerces-c-2.7.0-r1.

Thanks a lot for your help

Strange. Seems that it's just a problem on amd64 machines.

On my old Athlon XP xalan-c 1.10.0 compiles fine with xerces-c 2.8.0. Also on
my P4.

Only on my Athlon X2 I cannot compile xalan-c with xerces-c 2.8. Thus
"Hardware" should be changed to "amd64" instead of "all"

"fun with 64 bit" as usual :-(


@snoapx  
sorry for confusing you by writing unclear package names

confirm this bug on my amd64 laptop

As a temporary workaround you can try to merge dev-libs/xerces-c-2.8.0 without
the iconv USE-flag or with the icu USE-flag set.

ok, upstream only guarantees compatibility of xalan-c with xerces-c-2.7.0, not
with 2.8.0.
I therefore changed the dependency in xalan-c to only match xerces-c-2.8.0.
Those who upgraded have to downgrade again, I'm sorry.

Those who need both xerces-c-2.8.0 and xalan-c have two options:
a) create a custom overlay with a xalan-c ebuild in it where the dependency
matches xerces-c-2.8.0 as well and build xerces-c either with "-iconv" or with
"icu" (xalan-c builds then as well but I don't know whether it also works)
or
b) report to upstream that they should release an updated xalan-c.

Sorry for the inconvenience,
Cheers.

Weird. I was able to compile xalan against xerces-2.8 with USE=iconv

[ebuild   R   ] dev-libs/xerces-c-2.8.0  USE="iconv threads -debug -doc -icu
-libwww" 0 kB
[ebuild   R   ] dev-java/xalan-2.7.0-r5  USE="-doc -source" 0 kB

Isn't fixed until it's fixed.

Some references that might be of interest for investigating this issue here.

http://article.gmane.org/gmane.text.xml.xalan.c%2B%2B.user/3320
Xalan dev stating that current trunk should build against xerces-c-2.8.0

http://article.gmane.org/gmane.text.xml.xerces-c.devel/8414
Release information of xerces-c-2.8.0 calling it interface-compatible with 2.7

https://issues.apache.org/jira/browse/XALANC-652
Closed upstream bug with a patch to xalan trunk that seems not to be included
in the xalan-c-1.10.0 sources. Not sure that's self contained, though.

It feels like we might need to wait for the next xalan-c release, or grab a
snapshot, or backport some patches. Or use one of the workarounds above.

That dep just makes things worse.

It seems xalan-c-1.10.0 actually builds against xerces-c-2.8.0 and works
correctly.
Right now Virtualbox is pulling newer version of the latter, which creates a
dependency conflict.
It's fixable by masking newer xerces-c, but that's unneeded. Just fix the
xalan-c dep.

my updates for 'world' or 'virtualbox' have been blocked for weeks because of
this issue it seems.... still no workaround/fix ??

I dropped the iconv USE-flag (and support) in xerces-c-2.8.0-r1 due to other
problems with the iconv support in xerces-c-2.8.0.
This means that xalan-c can actually use xerces-c-2.8.0 again.
