The LDFLAGS -Wl,--as-need cause linking errors sometimes. This flag bring not so much benefits, but problems.
My request is to remove that flag from default LDFLAGS in makepkg.conf.

For example see vimprobable2 in aur repo.

This flag has a lot of benefits; it reduces dependencies to a minimum and safes us a lot of time because less packages need to be recompiled during so bump rebuilds. Most (nearly all) packages compile with --as-needed. If one doesn't just remove it withn that special PKGBUILD.

is hard to do "unset LDFGLAS" ?

@Pierre: is that so? Binaries should be linked only against needed libs. --as-need help only then yuo try link you programm against lib, that not really needed. I don't think, this is the case very often.

@wonder: I don't wont to eliminate all LDFLAGS.

then use:
export LDFLAGS="${LDFLAGS//-Wl,--as-needed}"

@wonder: nice (don't work in dash). I have solved the problem for the package, but i don't really like --as-need as default linker flag.

makepkg uses bash not dash so that is not an issue.

There is no way that --as-needed is every being removed from the default LDFLAGS. It breaks a few packages where upstream do not know what they are doing but it saves us A LOT of trouble.
