[jira] Commented: (XERCESC-1022) XMLPlatformUtils::isAnySlash()
causing dynamic loading errors
[ https://issues.apache.org/jira/browse/XERCESC-1022?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12605970#action_12605970 ]
Boris Kolpackov commented on XERCESC-1022:
------------------------------------------
If this is such a serious problem I am surprised nobody else is complaining about it. Or is it only a problem for older g++ versions (2.96)?

> Key: XERCESC-1022
> URL: https://issues.apache.org/jira/browse/XERCESC-1022
> Project: Xerces-C++
> Issue Type: Bug
> Components: Build
> Affects Versions: 2.3.0
> Environment: Operating System: Linux
> Platform: All
> Reporter: Jason E. Stewart

> Hey,
> I've had a large number bug reports in Xerces-P for the 2.3.0 release related to
> linking errors with isAnySlash(). For OS X the problems was eliminated by
> removing the 'inline' directive from the .cpp file and recompiling. For Redhat
> Linux this did not help, and Xerces-P was forced to remove the method from the
> API to enable linking.
> I'm at a loss to figure out why this one method should create problems on two
> such different platforms. The linux user was using an old version of gcc (2.96),
> so perhaps this is an issue?

> # nm -C

> # | grep -i isanyslash
> 0005de34 T _wrap_XMLPlatformUtils_isAnySlash
> U xercesc_2_3::XMLPlatformUtils::isAnySlash(unsigned short)
> So, I guess the error message is correct in reporting that the symbol is
> undefined. I'm in a little over my head with all this compiler/linking
> stuff though. How can I fix this?
