Re: NCARG Linker Problems

I looked in config/Projects, and the following ymake directives show this:

#ifdef BuildShared
NCARGCLIB = -lNGc
NCARGLIB = -lNGllu
CNCARGLIB = -lNGlluC
NCARGGKSLIB = -lNGgks
NGMATHLIB = -lNGmath
CGMLIB = -lNGcgm
NCARGRASLIB = -lNGras
HLULIB = -lNGhlu
NGOLIB = -lNGgo
XCBLIB = -lXcb
NFPLIB = -lnfp
NCLLIB =
NCLAPILIB = -lNGncl

I will disable BuildShared and see what happens (I defined that in
config/Site.local). Are there any known bugs with building the shared
libraries? Not to nit-pick, but why does the distribution default to a
different naming scheme for them (I know that I never modified these
values intentionally) since the linker should negotiate that
automatically with the -static or -shared flags?
