Hi, Can anyone tell me in which library of X windows following functions are defined? XwTextCopyBuffer XuInsertCursor XuRemoveCursor XuInsertNewLine XwTextSetInsertPos XwtexteditWidgetClass XwTextReplace XwTextClearBuffer Or to put it in other way, which library I should include in my Makefile in order to avoid "Undefined symbol" error related to above mentioned functions? Thanks Smitha
