Re: [sage-support] Re: [mpir-devel] Re: [sage-devel] MPIR 1.3.0 released (at last)
OK, the problem is as follows. For very straightforward C programs, no problems occur on t2 because the compiler emits inline code for everything. However, once the program becomes too complicated for it to do this, it uses libgcc: http://gcc.gnu.org/onlinedocs/gccint/Libgcc.html The problem is, when the compiler compiles such a program, the linker does not know where to find libgcc on the machine. It needs to know that it is in: /usr/local/gcc-4.4.1-sun-linker/lib/sparcv9 However, this is not in /etc/ld.so.conf, which does not exist on Solaris machines, nor is it in LD_LIBRARY_PATH. Why it won't work with this in LD_LIBRARY_PATH_64 I do not know. But either way, this problem is not something we can work around in MPIR, that I know of. It's just that MPIR uses some very complex arithmetic expressions for which gcc is unable to emit inline assembly. Even writing a basic test case that exhibits this failure would be difficult. I've no idea what the solution to the problem is. Back to the sparc expert for this one!

Re: [sage-support] Re: [mpir-devel] Re: [sage-devel] MPIR 1.3.0 released (at last)
Ah, got it. LD_LIBRARY_PATH_64 needs to also contain /home/wbhart/mpir-1.3.0/.libs. Basically if LD_LIBRARY_PATH_64 is not specified at all, i.e. left blank, the linker uses whatever is in LD_LIBRARY_PATH. Otherwise it uses LD_LIBRARY_PATH_64 exclusively, which means that *all* 64 bit library paths must be in LD_LIBRARY_PATH_64. So, in order to make MPIR work on t2, we'd need LD_LIBRARY_PATH_64 to be set globally for users *and* we'd need libtool to recognise that it needs to set LD_LIBRARY_PATH_64. Unfortunately libtool doesn't do this automatically. So this is seems to be a bug in the version of libtool we use. Another solution is to set LD_LIBRARY_PATH_64 to include $LD_LIBRARY_PATH. This actually works because the substitution is done live by the shell. In other words, if LD_LIBRARY_PATH_64 is set to /usr/local/gcc-4.4.1-sun-linker/lib/sparcv9:$LD_LIBRARY_PATH for all users of t2 globally, I believe MPIR will work just fine on that machine.

Hi, I've search on http://rpy.sourceforge.net/ and use R with commands inside a Sage script as following: from sage.all import * def iunif(a,b): return Integer(fround(r.runif(1,RDF(a),RDF(b)),0)) def runif(a,b,prec): return RDF(fround(r.runif(1,RDF(a),RDF(b)),prec)) def rbernoulli(): return r.rbinom(1, 1, 0.5)._sage_() From Sage I've used RDF because R needs reals and not symbolic expressions and used _sage_() to convert from R objects to Sage objects.

The reason I asked is that I was that we just presented how to use FEMhub (femhub.org), which is based on Sage (it doesn't contain R though) at our colloquium, and then I was in the computer lab and one professor was teaching statistics in R, explaining how to download/install it, and then they were using it as a desktop application, so I had first hand experience how people use R. And I am glad I use Python. The devil is in the details. So I will mention Sage to him together with some examples how to use R in it.

[sage-support] COIN Linear Programming
Hi!
I'm trying to use COIN to solve a MixedIntegerLinearProgram in sage.
When I get to the command
sage: p.solve(solver=Coin)
I get an error saying Coin/CBC is not installed and cannot be used
to solve this MixedIntegerLinearProgram. To install it, you can type
in Sage: install_package('cbc')
However, I have installed Coin/CBC. And in fact, if I try the command
sage: install_package('cbc')
I get an error saying Package is already installed. So one part of
sage thinks it is installed, while another does not!
Any help on resolving this issue would be greatly appreciated. The
sage install is a source install on an ubuntu server.

I think the mismatch is due to the compiled Sage library, which lives
under SAGE_ROOT/devel/sage/. After you have installed CBC or GLPK, you
also need to run the command
./sage -b
This would get Sage in sync with the installed CBC or GLPK library.
The way MixedIntegerLinearProgram, or an interface to CBC/GLPK, is
written is that when you compile Sage from source, the relevant part
concerning CBC/GLPK is not compiled together with the Sage library.
After you have compiled Sage and you have installed CBC or GLPK, you
also need to invoke the above command so that the relevant interface
to CBC/GLPK is updated to account for the newly installed library.
Someone recently emailed me about this as well. Here's my response, so
it's recorded somewhere for people to read:

Is there a way in spkg-install to ask sage to rebuild itself
after adding the packages ?
You could put the following line at the end of the installation script
spkg-install
$SAGE_LOCAL/bin/sage-build
The command sage -b invokes that script. I patched glpk-4.38.p4 with
this line. But no matter how much I tested out the patched GLPK spkg,
I would still need to do ./sage -b to get Sage to build the GLPK
specific code. Putting the following line at the end of spkg-install
works
$SAGE_LOCAL/bin/sage-build -b
But this will actually rebuild the whole Sage library, which takes
much longer than if you do ./sage -b. Perhaps you could mention in
the documentation for the function/class that uses GLPK/CBC, asking
user to run ./sage -b after installing any of these two spkg's.
People on the sage-devel mailing list might know of a better way to
patch spkg-install for GLPK or CBC.

[sage-support] Re: COIN Linear Programming
Hello Tyler !!! Minh, as is his custom, gave you the perfect answer. I also received several emails about it, and I am still trying to design an acceptable answer. For the moment, I only added a line about it at the end of a tutorial on LP using Sage, which may interest you too : http://bit.ly/5lUslr Thank you for reporting such bugs :-) Nathann -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
Re: [sage-support] Cannot run Sage
Hi,
If you got the binary version of sage-4.3.1 for 32-bit Arch Linux from
the downloads web page, it's the one I built on my system. And sure
enough, I had the same problem as you yesterday.
Let me guess: did you update your system? In particular, did you
upgrade your gcc from 4.4.2 to 4.4.3 recently? Somehow that messes
things up (I'm not sure why). In any case, I had to rebuild Sage from
scratch on my machine.
I will make a new binary distribution and upload it somewhere, and I'll
send you the link when that's done.
Best,
Alex

Hi guyz...
im using the binary version of sage for Arch Linux. However, when i run
sage, i got a long error message. I post the error message on the
attachment.
I was able to use sage before, without any error. But the error occured this
morning. so im actually confused why i got the error.
Thanks in advance
