Dear Team,
Thanks for your reply and it helps me to recompile the octave from source code.
QScintilla library was already installed.
Work Arround as follows:
a) Installed fltk & fltk-devel
b) Recompiled the octave source code
Error resolved by changing the cc files after commented undefined symbol/function as setMarginType not supported for class octave_qscintilla
libgui/src/m-editor/file-editor-tab.cc:156
libgui/src/m-editor/file-editor-tab.cc:183
Now Text Editor is working for me within the Octave UI.
octave-4.2.1/libgui/src/m-editor # diff file-editor-tab.cc file-editor-tab.org-cc
