Bug 399557 – sci-mathematics/octave-3.6.0 violates EAPI by using tc-has-openmp() in pkg_pretend

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Tiziano Müller (RETIRED) 2012-01-20 21:28:29 UTC]

The tc-has-openmp() function in the toolchain-funcs eclass assumes $T to be defined and writes to the filesystem which is not allowed in the pkg_pretend phase according to EAPI 4 and octave thus breaks EAPI-compliant package managers:

fixed by switching to pkg_setup. thanks.
