Created attachment 254233 [details, diff] tachyon.patch alexxy, sci-herd: I would like to apply this change to the tachyon ebuild, preferably to rev -r2. My make_arch func makes most of the flag sedding unnecessary, and allows more control over how the targets are built. Make-arch does nothing more than setting some defines, cflags (for optimisation) and libs.
Same problem for me. Your patch works for me. I had to add the USEFLAG threads to tachyon to have a successfull build. Thanks !
If you add ~x86-linux, please also add ~amd64-linux. Thanks!
Looks good to me. @alexxy: You or me?
The recent version, tachyon-0.98.9-r2, contains prefix love from the sci overlay.
