[sage-release] were ubuntu 14.04 binaries of 7.0 meant to work on any x86_64 CPU?

2016-05-11 Thread Dima Pasechnik
It appears that this report 
https://groups.google.com/d/msg/sage-support/fseE3_tQoQE/BCbFrskFCgAJ
is an indication that these binaries are slightly broken; namely, an 
optional package csdp compiled on it
gets faulty executables (they use blas/lapack/atlas in a nontrivial way).

Could it be that SAGE_FAT_BINARY was not set for the build, or something 
like this?

Just wondering,
Dima

[sage-release] Re: Reverting blacklisting of GCC 4.8 (#20231)

2016-05-11 Thread Eric Gourgoulhon
+1 for still supporting GCC 4.8 for a while (unless it's very troublesome): 
this is the GCC version of Ubuntu 14.04 LTS, which is officially supported 
until April 2019. 

Eric.

If you make a ticket then I'm happy to merge it...

[sage-release] Reverting blacklisting of GCC 4.8 (#20231)

2016-05-11 Thread Jeroen Demeyer

Hello Volker,

would it be okay for you to revert Trac #20231 in Sage 7.2? The reason 
for blacklisting GCC 4.8 was to support #20226, but that's not going to 
be merged in Sage 7.2. So maybe it's best to still support GCC 4.8 in 
Sage 7.2 (maybe with a deprecation warning in configure.ac).


When #20226 gets merged in some later beta, we can then either re-merge 
#20231 or find a work-around to make it work with GCC 4.8.
