While gold is part of the problem it is not completely its fault in my opinion. gold I think default to "as-needed" sage/rings/model. complex_double.pyx doesn't directly call cblas so gold doesn't see it as needed and drop it. The problem here is that libgsl itself is not linked properly for it to work - regardless of gold. If you check the readelf -d output for libgsl there is no mention of libcblas/libgslcblas in the nedded section. So the libgsl doesn't even know where to find its undefined symbols. I guess gold may be made to work here if we can convince it to include libcblas in the needed section of complex_double.so. But I think we should fix the somewhat fishy stuff in libgsl, sure it is legal and all in that you can link with the libclas of your choice and gold may even do the right thing for an executable where all symbols have to be resolved but a .so? Well undefined symbols is legal for a library.....
So I would like to know what libgsl looks like before Jean-Pierre's fix for cygwin.

Which apparently can't link Sage. To fix this, uninstall binutils-gold. Gold is geared towards C++ so I'm not too surprised that it fails. Its also relatively new, especially for OP's linux version.

However I have $ ld -v GNU ld (GNU Binutils for Ubuntu) 2.22 and the linking is good. I had some other hiccups, mainly with cvxopt, when building 6.1.1 but eventually the build completed. I'm not sure why there is a difference in Binutils? On Friday, February 7, 2014 10:13:34 AM UTC-6, sho...@ualberta.ca wrote: Well I did build it successfully once. It was on 12.04 Ubuntu that had been used a lot - many softwares built on it. I then upgraded to 13.10, had many problems, and then decided to reinstall (fresh) 12.04LTS over the top (even reformatted) of 13.10. So in essence, my Ubuntu is pretty new and may not have a lot of "stuff", even though it does have all the prerequisites. I've actually tried to build 5.13, 6.0, and 6.1.1 and none have worked. It always complains about "conway_polynomail".... I have the log files still too if that can help. I'll try the GIT build today and see what happens. I've also wondered about the PPA build of sagemath, though I don't like the idea of not having a self-contained directory/tree - maybe though it would install something in my /usr/bin or /usr/lib, etc. that I'm missing..... Thanks for the suggestion. Brett On Friday, February 7, 2014 7:40:08 AM UTC-7, Niles Johnson wrote: On Thursday, February 6, 2014 8:39:14 PM UTC-7, François wrote: I am stumped. I will have to think it over for a bit. Output of "ld -v" please. While François is thinking, I'll make some other (more rudimentary) suggestions. * Have you successfully built older versions of sage? What is the latest one that builds? * Are there any other packages failing to build? (My guess is no.) * Could you try checking out and building from the git repository (this shouldn't make a difference, but who knows!?) [if you checkout the git repository, you can easily roll back to older versions with, e.g., git checkout 6.0] * In particular, maybe try building the develop branch, just to see whether you get the same or different problems -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
