Sounds good! Here my proposed changes:
1. I'll add to buildtools/conf/MonetDB.m4
MATH_LIBS=""
AC_CHECK_LIB(m, main, [ MATH_LIBS="-lm" ] )
AC_SUBST(MATH_LIBS)
2. I'll look after -lm in
MonetDB4/src/modules/calibrator/Makefile.ag: LDFLAGS = -lm
MonetDB4/src/modules/calibrator/Makefile.ag: LIBS = -lm
MonetDB4/src/modules/contrib/Makefile.ag: LDFLAGS = -lm
MonetDB4/src/modules/contrib/Makefile.ag: LDFLAGS = -lm
MonetDB4/src/modules/mnetcdf/Makefile.ag: LDFLAGS = -lm $(NETCDF_LIBS)
MonetDB4/src/modules/plain/Makefile.ag: LDFLAGS = -lm
MonetDB5/src/modules/atoms/Makefile.ag: LIBS = $(MONETDB_LIBS) -lbat
-lstream -lm \
MonetDB5/src/modules/kernel/Makefile.ag: LDFLAGS = -lm
MonetDB5/src/modules/mal/Makefile.ag: LIBS = ../../mal/libmal
$(MONETDB_LIBS) -lbat -lstream -lm \
MonetDB5/src/optimizer/Makefile.ag: LDFLAGS = -lm
and substitute it with LIBS = ... $(MATH_LIBS)
3. I'll add to MonetDB/conf/rules.msc:
MATH_LIBS =
OK?
Steffen
