3.3.4. Separate builds¶
Especially when developing, it saves time to have separate build_*/
directories; one for each combination of SOLVER
and OPTS
.
This may be enabled by setting the make macro SEPARATE_BUILDS
,
e.g. in a $(TOP)/options.mkf
file (which might also be used to
set the COMPILER
and other macros). The file could thus contain,
for example:
COMPILER=ifort
SEPARATE_BUILDS=on
