Re: Re: Re: Re: A question about how to throw out and catchaselfdefinedexceptions
Hi Alberto Massari,
Sorry for misunderstanding your meanings,My command line for runConfigure
is just as following:
runConfigure -plinux -cgcc -xg++ -minmem -nsocket -tnative -rpthread
I run it when my first build of xerces,should it be run another time?
Thanks Alberto.
Best wishes!
Roger

No, you don't need to run it again; I just needed
to have a look at it, so that I now know that you
are using the "InMem" message loader, so what you should do now is:
- edit the
src/xercesc/NLS/EN_US/XMLErrList_EN_US.Xml to add
the message (being an error related to parsing,
the proper location would be under the
<FatalError> element of the <MsgDomain
Domain="http://apache.org/xml/messages/XML4CErrors">)
- compile the utility found at tools/NLS/Xlat
- run it using
Xlat /SrcRoot=C:\Xerces-C\ /OutPath=c:\temp\ /OutFmt=CppSrc /Locale=EN_US
- get the XercesMessages_en_US.hpp file from the
output directory and place it in the
src/xercesc/util/MsgLoaders/InMemory folder
- get the XMLExceptMsgs.hpp file from the output
directory and place it in the src/xercesc/util folder
- recompile
Hope this helps,
Alberto
