Hi Alex, hi all.

I was thinking that that can be the case.

Well, my expat is installed from debian, so it's stripped.

But, I run the nm in the generated lib in /usr/local/lib/lua/5.0

Just look a excertp fron the exit:
00003640 r validkeys.2751
         U XML_ErrorString
         U XML_ExternalEntityParserCreate
         U XML_GetBase
         U XML_GetCurrentByteIndex
         U XML_GetCurrentColumnNumber
         U XML_GetCurrentLineNumber
         U XML_GetErrorCode
         U XML_GetSpecifiedAttributeCount
         U XML_Parse
         U XML_ParserCreate
         U XML_ParserCreateNS
         U XML_ParserFree
         U XML_SetBase
         U XML_SetCdataSectionHandler
         U XML_SetCharacterDataHandler
         U XML_SetCommentHandler
         U XML_SetDefaultHandler
         U XML_SetDefaultHandlerExpand
         U XML_SetElementHandler
         U XML_SetEncoding
         U XML_SetExternalEntityRefHandler
         U XML_SetNamespaceDeclHandler
         U XML_SetNotationDeclHandler
         U XML_SetNotStandaloneHandler
         U XML_SetProcessingInstructionHandler
         U XML_SetUnparsedEntityDeclHandler
         U XML_SetUserData

I have expat.h in /usr/include (from Debian).

That is the makefile that I'm using:

I don't know where is my error :(

(Well, I don't usually compile my libs too :( )

Thanks on advance!
