It's hard to guess what error you get since you have not
included the output or a more complete example. But my
guess is that you've not quoted the variable you're passing
to --define. Here's an example spec and some example
output:
$ cat test.spec
Name: test
Version: 1.0
Release: 1%{?dist}
Summary: Test spec
License: MIT
%description
%{summary}.
%prep
%if 0%{?_me}
echo "_me == %{_me}"
%else
echo "_me != 1"
%endif
#
# Running without --define shows the %else clause is reached
#
$ rpmbuild -bp test.spec
Executing(%prep): /bin/sh -e /home/tmz/src/packages/tmp/rpm-tmp.po8R74
+ umask 022
+ cd /home/tmz/src/packages/test
+ echo '_me != 1'
_me != 1
+ exit 0
#
# Running with --define unquoted shows a failure
#
$ (_def1="_me 1"; rpmbuild -bp --define=$_def1 test.spec)
error: Macro %_me has empty body
#
# Running with --define quoted shows the %if clause is reached
#
$ (_def1="_me 1"; rpmbuild -bp --define="$_def1" test.spec)
Executing(%prep): /bin/sh -e /home/tmz/src/packages/tmp/rpm-tmp.jcPyKb
+ umask 022
+ cd /home/tmz/src/packages/test
+ echo '_me == 1'
_me == 1
+ exit 0
If you're experiencing some other sort of failure, it would
be useful if you included a shortened spec file and the
rpmbuild commands and output.

Honesty may be the best policy, but it's important to remember that
apparently, by elimination, dishonesty is the second-best policy.
