[sage-devel] error compiling ntl in sage 7.3.beta8

Surely this means exactly what it says, since the IP address of trac really has changed. John On 19 July 2016 at 14:47, mmarco wrote: > Trying to `git trac push` I get the following error message.

While you cannot pass options directly to NTL's 'configure' (without editing build/pkgs/ntl-*/spkg-install), you could for example do $ env SAGE_FAT_BINARY=yes ./sage -i ntl $ make # continue the build without "fat" binary enabled (I *thought* there was also an "experimental" binutils Sage package, but that doesn't seem to be the case, at least there isn't any on the official Sage mirrors.) > P.S.: That's a known bug (NTL not checking whether the assembler can > cope with GCC's output in case of '-march=native'), but this so far has > hit us only on MacOS X.

Well, in this case Sage built and used its own GCC (currently 4.9.3) because at least /the default one/ on your system is outdated as well. You may ask the sysadmin whether already a newer version is available on your system (you could use for Sage by changing your PATH or setting CC, CPP, CXX and FC accordingly), and if not, ask him to install one (along with newer versions of its prerequisites such as GMP, MPFR, MPC, and other updated toolchain parts such as binutils) to be optionally used for performance reasons (and also e.g. C++11 support). The CPU is a "Haswell-EP" which supports (among other extensions) AVX2 and BMI2 (where "shlx" belongs to), so it's worth to use a more recent compiler on it, as Volker mentioned. -leif > Your idea with SAGE_FAT_BINARY seems to get around the problem, by now. > > If it still helps for #20779: > > sageadm@pmlapsag01:~/sage$ as --version > GNU assembler version 2.20.51.0.2-5.44.el6 20100205 > Copyright 2009 Free Software Foundation, Inc. > This program is free software; you may redistribute it under the terms of > the GNU General Public License version 3 or later. > This program has absolutely no warranty. > This assembler was configured for a target of `x86_64-redhat-linux'. > > > -- > sageadm@pmlapsag01:~/sage$ head -25 /proc/cpuinfo > processor : 0 > vendor_id : GenuineIntel > cpu family : 6 > model : 63 > model name : Intel(R) Xeon(R) CPU E5-2660 v3 @ 2.60GHz > stepping: 2 > microcode : 46 > cpu MHz : 2593.993 > cache size : 25600 KB > physical id : 0 > siblings: 2 > core id : 0 > cpu cores : 2 > apicid : 0 > initial apicid : 0 > fpu : yes > fpu_exception : yes > cpuid level : 15 > wp : yes > flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge > mca cmov pat pse36 clflush dts mmx fxsr sse sse2 ss ht syscall nx > pdpe1gb rdtscp lm constant_tsc arch_perfmon pebs bts xtopology > tsc_reliable nonstop_tsc aperfmperf unfair_spinlock pni pclmulqdq ssse3 > fma cx16 pcid sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes > xsave avx f16c rdrand hypervisor lahf_lm abm ida arat epb xsaveopt pln > pts dtherm fsgsbase bmi1 avx2 smep bmi2 invpcid > bogomips: 5187.98 > clflush size: 64 > cache_alignment : 64 > address sizes : 42 bits physical, 48 bits virtual > power management: > -- You received this message because you are subscribed to the Google Groups "sage-devel" group.

[sage-devel] Re: Current best practice for LaTeX of function names
Ralf, I'm finally getting ready to add/standardize LaTeX names for special functions. I wanted to start with elliptic integrals but see that latex_name or _print_latex_ are already defined for all of them. The LaTeX formatting shows at the command line but does not get rendered in notebooks or SageMathCell. Since elliptic integrals are all BuiltinFunction, what would be blocking the rendering of LaTeX?

Just FYI - Tom Roby and I ran into this problem today trying to get 7.3.beta8 to build on OS X 10.9. So a fix before 7.3 is released would be good and appreciated.

Re: [sage-devel] Re: Git repository should have Sage versions as branches not tags
I was running a small script on trac.sagemath.org:12000 that was listening for github pull requests and comments (via github webhooks) and publishing them to trac (via the trac scripts shipped with Sage). Nothing too fancy, but I can't find the code for it at the moment (but it's probably still sitting in that image unless it's been redone since then). I don't remember if I ever pushed anything back to github (which would require write access) but pull requests should get closed when their associated changes get merged into master.
