Ahhh, some more is needed:

--- a/Makefile
+++ b/Makefile
@@ -21,7 +21,7 @@
 CONFIG ?= fltk-config
 PDF_PS_FLAGS ?= -DNO_PDF

-EXTRALIBS = `$(CONFIG) --use-images --ldflags`
+EXTRALIBS = `$(CONFIG) --use-images --ldflags` -lz -lpthread -ldl

 CC = gcc
 CXX = g++


I wonder how this could work at your side ...

Will be uploaded soon
