Hmm. I reinstalled the external plugin, by changing its ./configure script.  Added -fPIC to its CFLAGS, CXXFLAGS and FFFLAGS.  It looks something like that:
CFLAGS = -g -O2 -fPIC

Then it appears in the makefile.  I deleted the old libopt.a, and ran 'make install' to create it again.  But YADE still gives me the same error.  Do you know what I should do?  I am really lost.


Yours,

Boon
