[makepkg] depends version check problems

roadt · 2008-07-23 07:27:18

hello everyone,
i want to make a simple PKGBUILD of tijmp, it need the jdk6 as the dependence.

In my PKGBUILD, i wrote

depends=('jdk>=6')

but when makepkg -f , makepkg reports errors.

==> Making package: tijmp 0.7-1  (Wed Jul 23 15:26:11 CST 2008)
==> Checking Runtime Dependencies...
==> Missing Dependencies:
  -> jdk>=6
==> Checking Buildtime Dependencies...
==> ERROR: Could not resolve all dependencies

my jdk version is 6u7

$P -Qi jdk
Name           : jdk
Version        : 6u7-1
URL            : http://java.sun.com
....

but if i changed the PKGBUILD, like

depends=('jdk>=6u')

makepkg works well.

why?

This happens because according to the version comparison 6 > 6u7 but 6u < 6u7 - you can test this with the vercmp tool. This is because any text after a number is assumed to mean something like alpha, beta, rc, etc. It is difficult (read impossible) to come up with a version comparison function that works for every piece of software.

Thanks Allan.

it's difficult to create a rule for apply for all people. agreed.

but if the vercmp works as this rule, i suppose jdk 6u7 is wrongly named.
since u7 is neither alpha nor beta. (though i still doesn't understand what u7 or u mean).
maybe 6.7 or something similar is better. why using u7? that's strange for me..

Jdk is named 6u7 because that is what upstream calls it so not much we can do about that.

yes, google some, seems named as 6 Update 7 .

okay. i'll keep the depends=('jdk>=6u') in PKGBUILD.
it's not too ugly to live with, and seems i have no choice. :-)

Thanks for your help.
