Hi,

I am trying to understand the following lines in a spec file.

The spec file is from the fedora postfix rpm and I would like to rebuild the rpm with mysql enabled. I think that I can simply change the first line to say %define MYSQL 1 but I am wondering if there is a parameter I can pass from the rpmbuild command line so that I do not have to modify the spec file.

Can someone please tell me how to get the srpm to build with mysql enabled without modifying the spec?

%{?!MYSQL: %define MYSQL 1} %{?!PGSQL: %define PGSQL 0} %define LDAP 2 %define PCRE 1 %define SASL 2

rpmbuild --define "MYSQL 1" ...

Common options for all rpm modes and executables: -D, --define='MACRO EXPR' define MACRO with value EXPR
