Description Adrian von Bidder 2009-11-19 12:17:28 UTC

Version:            (using Devel)
Compiler:          GNU tool chain 
OS:                Linux
Installed from:    Compiled sources

Heyho!

As discussed a long time ago:

-Wl,--as-needed -Wl,-z,defs should be used to compile and link (almost) all applications.

This makes the dependency lists of distribution packages much smaller, allowing for easier upgrades of libraries (I know this for a fact for the Debian unstable -> testing cycle, but probably other distributions face similar problems.)

I'm currently using these flags for the Debian package, but I think they could as well be used by default instead of in a Debian specific addition.

(... is there a bugzilla category for the KDE default build system as a whole?  I *think* that the flags might as well be used by default on any ELF based platform where the GNU toolchain is used.)

This is something the buildsystem team needs to decide about.
