Re: [Numpy-discussion] building NumPy with gcc if Python was built with icc?!?

2016-02-16 Thread Nathaniel Smith
In principle this should work (offer may be void on windows which has its own special weirdnesses, but I assume you're not on windows). icc and gcc should both support the same calling conventions and so forth. It sounds like you're just running into an annoying build system configuration issue

Please correct me if I misunderstood, but the code in that commit is doing a full sort, somewhat similar to what `scipy.stats.scoreatpercentile`. If that is correct, I will run some benchmarks first, but I think there is value to going forward with a numpy version that extends the current

I'm not sure about anyone else, but having been playing around with both gcc and icc, I'm afraid you might be out of luck. Is there any reason why you can't use a Python distribution built with gcc? On Tue, Feb 16, 2016 at 7:39 PM, BERGER Christian wrote: > Hi All, >

2016-02-16 Thread BERGER Christian
Hi All, Here's a potentially dumb question: is it possible to build NumPy with gcc, if python was built with icc? Right now, the build is failing in the toolchain check phase, because gcc doesn't know how to handle icc-specific c flags (like -fp-model, prec-sqrt, ...) In our environment we're
