I recieved this error while "make" the library
the makefile is:-
-----------------------------
if WITH_OPTIONAL_DIRS
optional_dirs = test doc testsuite
else
optional_dirs =
endif

SUBDIRS = ora utils matvec solver mllib export examples flens \
$(optional_dirs)
DIST_SUBDIRS = ora utils matvec solver mllib export examples flens test doc

EXTRA_DIST = ac_prog_perl_modules.m4 acx_blas.m4 acx_lapack.m4 boost.m4 \
libtool.m4 lang.m4
--------------------------

the error is:-
Makefile:1: *** missing separator. Stop.
Thanks on advance

Maybe this is not what you mean. The "if" statement is interpreted as a conditional statement for the shell and as such it requires a leading TAB, as for any other command to be executed by the shell. Hence the "missing separator" error. To check if a variable is defined use ifdef instead.

A suggestion for some good reading about Make programming: http://oreilly.com/catalog/make3/book/index.csp
