Greetings from Guix! [0] We're having trouble building ilmbase-2.2.0 for the i686 architecture on Linux, with gcc-4.9.3.
The build process fails during testing. Specifically, it fails testBoxAlgo, like this: ImathTest: testBoxAlgo.cpp:892: void {anonymous}::boxMatrixTransform(): Assertion `b21 == b2' failed. /gnu/store/isxqjfaglyfsbcv75y8qbqbph8v28ykr-bash-4.3.39/bin/bash: line 5: 4565 Aborted ${dir}$tst On our mailing list, this was suggested as the nature of the problem [1]: On Mon, Nov 30, 2015 at 10:14:49PM +0200, Ludovic Courtès wrote: > Right.

Here is the build system's web page for this particular build... http://hydra.gnu.org/build/729299 ... and the full build log... http://hydra.gnu.org/build/729299/nixlog/1 ... and an exhaustive list of build dependencies (be patient, it may take a few seconds to load)... http://hydra.gnu.org/build/729299#tabs-build-deps We have no problem building on x86_64, armv7, or mips64el.
