I looked at the diff. From what I can tell, you remove -lm from the LIBS if
not present. Which I believe is incorrect way to do it but I would like
another dev to say if I am wrong or right.
What I was trying to get at was:
IF Haiku ( or BeOS or Zeta ) & program links to libm
change -lm to -lroot // because there is no libm in Haiku/BeOS - part of
libroot
else ( for Linux )
leave it as -lm
Actually, the easiest & quickest way is to symlink libm->libroot so no code
changes would be needed at all but some devs do not like hacks :- )
I believe devs link to libm in their programs for a reason ( else, why put in
-lm if not needed?? ) and removing the linking to libm is not the right way to
do it. Could cause issues. That we should link to libroot instead when a
program wants libm.
Can someone clear this up because maybe I am confused? If a POSIX program is
looking for libm should we:
a) just remove -lm ( not link to libm ) or
b) change -lm to -lroot ( to link to libroot instead of libm )
From what I can tell, Scott is doing a) and I believe it should be b). If a),
then can someone also explain why a program would use -lm if it is not needed.
