RPM spec files

Macros

• %{?the_variable} : if the_variable is not defined, this is replaced with an empty string
• 0%{?the_variable} : if the_variable is not defined, this is replaced with 0

Multiple conditions in %if

You can use round parenthesis:

%if 0%{?other_version} >= 11 || ( 0%{?is_foo} && 0%{?foo_version} >= 10 )

Evaluate some spec file content

• Create a dummy spec file, and then call:
• rpmbuild -ba dummy.spec

• rpmbuild -bp dummy.spec : only go thru %prep

• From command line: rpm --eval 'Foo: %{?foo_variable}'
