-SPEC file updated

Finally I got it almost done done, except only one error–”rpm build errors installed but unpackaged”. It took me almost another hour to tuning the less.spec. Then I run the “rpmbuild” without any error.

But that was only part of the job. When I run “rpmlint” command to test the spec file, binary file and SRPM, I still got some errors and warning. Fortunately, the system gave me very clear message, list the errors and warning, even point out the incorrect line related to the program. So the troubleshooting is not so difficult. It even point out my typo.

Now I will try with second command “wget”. Hope I will be back soon.

After downloaded and unzip the tarballs, they both need “configure” first, before we make the package.

time make for “less”

real    0m6.446s
user    0m5.641s
sys    0m0.755s

time make “wget”

real    0m3.135s
user    0m0.425s
sys    0m0.955s

These two commands are easy to build. However, I tested “less” command with the executable file, and I did not find the executable file for “wget” after build.
