I want to remake rpm package without srpm

401 views Asked by At
  1. Goal

    I have a rpm package, but I want to substitute several files in the rpm, and make a new rpm.

  2. Backgroud

    I couldn't find srpm of a certain software. What I could download is the rpm package.

  3. Operations

    a. I got the spec file from the rpm by rpmrebuild --package --notest-install -sxxx.spec xxx.rpm

    b. I got all the files in the rpm by rpm2cpio pkgname | cpio -ivd

    c. I copied the files from above into ~/rpmbuild/SOURCE, and copied the xxx.spec to ~/rpmbuild/SPECS

    d. I did rpmbuild -bb xxx.spec but I found File not found: for every file.

  4. Question

    I don't know how to solve this problem. Should I make a tarball of the files from rpm2cpio pkgname | cpio -ivd and then go to modify the spec file?

    Or I must install the rpm first and then try to run rpmrebuild to create a new rpm?

    I want to know the traditional way to solve this problem, thanks very much.

You relly need to open up that spec and adapt it to the files it expects. The spec file itself holds the answer to most of your questions:

  • The Source tag(s) will tell you the source files that are needed and their names.

  • The %files section will tell you what files are expected to be in the in the rpm after building it.

I advise you to open another question and post the spec file and a list of the files you extracted wit rpm2cpio
