How do you get environment variables into an rpmbuild command?
I have a need to do that, and I have tried using environment
variables in the
~/.rpmmacros file with limited success.
I have an environment variable that knows the version of the
software I am
building. It is named SW_VERSION. In the ~/.rpmmacros, I added
this line:
%version $SW_VERSION
In my specfile I have the following:
Version: %{version}
When I do the rpmbuild command, the Version appears to be handled
correctly
until rpmbuild writes the package file. In the package file, the
name of the
package includes the name of the environment variable (SW_VERSION)
instead of
the value in the environment variable (in this case, 3.2.0).
Since I call rpmbuild from a makefile, I have the makefile generate
a new
~/.rpmmacros file every time where I hard-code the version instead
of using the
environment variable. Is that the best I can do, or is there a way
for
~/.rpmmacros to use an environment variable?
Hope I made that clear.
There is no shell environment on the pathway that generates an output
file name within rpmbuild.
I.e. theshell environment is never looked at.
If you absolutely categorically adamantly insist on using environment
variables for rpmbuild, try
%myversion %(echo $SW_VERSION)
...
Version: %{myversion}
to supply a shell context for examining the environment.
Note the change from %version to %myversion to avoid another surprise.
