Or on systems that have the "env" program, you can do it like this:
|
||||
env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
|
||||
|
||||
The flags CFLAGS, CPPFLAGS, LDFLAGS and LIBS can also be set as flags to
|
||||
configure, where the name appears in lower case:
|
||||
configure --enable-cflags=-O2 --enable-libs=-lposix
|
||||
|
||||
The advantage of this form is that `config.status --recheck' will remember
|
||||
the flags you originally specified. You can still override the flags when
|
||||
running `make' (although these will not be passed down via `config.status
|
||||
--recheck').
