Hmm, I am not 100% sure the binary will run on a G3. IIRC some people have reported working binaries on G3 CPUs, but that might have been a while. Can you check if the md5sum of the dmg matches? mabsh...@sage:/scratch/mabshoff/sage-3.4$ md5sum ~/sage-3.4-OSX-10.4- PowerMacintosh-Darwin.dmg 3285260d94023d27a86faeb05bd0dcef /home/mabshoff/sage-3.4-OSX-10.4- PowerMacintosh-Darwin.dmg I do not think that this is the problem though - see below. > -- > | Sage Version 3.4, Release Date: 2009-03-11 | > | Type notebook() for the GUI, and license() for information. | > -- > The SAGE install tree may have moved. > Regenerating Python.pyo and .pyc files that hardcode the install PATH > (please wait at > most a few minutes)... > Do not interrupt this. > ImportError: dlopen(/Applications/sage/local/lib/python2.5/site- > packages/sage/misc/randstate.so, 2): Library not loaded: /tmp/fooo/ > sage-3.4/local/lib/libgmp.3.dylib >Referenced from: /Applications/sage/local/lib//libcsage.dylib >Reason: no suitable image found.

That might be caused by newer XCode releases, but I am not 100% sure. I do not think that we changed anything inside MPIR that would cause this.

[sage-support] using sage libraries in python script: QQ and rational_field.py
Hi, I have installed sage 3.4 from source. I want to use sage in my python scripts, particularly the linear algebra part. I therefore want to write little python scripts with something like m=matrix([[1,2],[3,4]]) e=m.eigenvalues() My only problem is: what should I import in order to make this kind of thing work? I figured out that you seemingly can import import sage.all This seems to reproduce the sage command-line functionality, i.e. I can do import sage.all m=sage.all.matrix([[1,2],[3,4]]) e=m.eigenvalues() However, I am not sure about that, and I did not find out where in what manual this is explained. And, I am importing a huge piece of software with this command. Therefore, I want to try something else. Looking up "eigenvalues" in the reference manual, I find that it resides in sage.matrix.matrix2.Matrix So, what I would like to do, is import sage.matrix.matrix2 and then use Matrix. However, this does not work: when trying to do this import, python reports an error. Here is the way to reproduce this error: cd $SAGE_ROOT/loca/bin source sage-env ./python >>>import sage.matrix.matrix2 Traceback (most recent call last): File "", line 1, in File "matrix2.pyx", line 1, in sage.matrix.matrix2 (sage/matrix/ matrix2.c:32616) File "matrix1.pyx", line 1, in sage.matrix.matrix1 (sage/matrix/ matrix1.c:9974) File "matrix0.pyx", line 32, in sage.matrix.matrix0 (sage/matrix/ matrix0.c:19609) File "/home/bn/sage-3.4/local/lib/python2.5/site-packages/sage/ modules/free_module.py", line 163, in import free_module_element File "free_module_element.pyx", line 111, in sage.modules.free_module_element (sage/modules/free_module_element.c: 19756) File "/home/bn/sage-3.4/local/lib/python2.5/site-packages/sage/rings/ arith.py", line 18, in import sage.rings.rational_field File "/home/bn/sage-3.4/local/lib/python2.5/site-packages/sage/rings/ rational_field.py", line 52, in import rational File "rational.pyx", line 63, in sage.rings.rational (sage/rings/ rational.c:17816) File "real_mpfr.pyx", line 143, in sage.rings.real_mpfr (sage/rings/ real_mpfr.c:25879) AttributeError: 'module' object has no attribute 'QQ' What is going wrong? And how should I, in general, use sage in a python script? Remember that there was no way to find out from the eigenvalues entry in the reference manual that you could actually import sage.all and use sage.all.matrix... So I do actually not know how to figure out that kind of problems in the future. If the import sage.matrix.matrix2 would work, I could use sage quite straightforwardly in my scripts, as I would then be able to use the info in the reference manual.

In Python, "^" represents the XOR operator where as "**" is exponentiation.
In [3]: 2**3
Out[3]: 8
In [4]: 2^3
Out[4]: 1
At the Sage command-line, the "^" are changed into "**" so that you'd
get the behavior you'd expect:
sage: preparse('2^3')
'Integer(2)**Integer(3)'
sage: 2^3
8

[sage-support] Operator precedence.
something strange happened to me today, if I try In [1]: 6*21/18-2^3 Out[1]: 6 However, if I try the following In [2]: 6*21/18-2**3 Out[2]: -1 then the normal operator precedence (parenthesis, exponential, multilplication-division-remainder, addition-subtraction) occurs. Does anybody have a comment on that?

[sage-support] Re: Special linear group on finite field
Judging from the error message "unable to coerce from a finite field other than the prime subfield", it seems that in Martin's examples a coercion is attempted from GF(p^a) to GF(p^b) where a>1. In David's example, the larger field is GF(3^2) so any coercion would be coming from GF(3), hence not covered by the error message. So I don't think it has to do with trac #5491. It is either a problem with Sage finite fields, or with translating between Gap finite fields and Sage finite fields. I'll have a closer look later today and open a ticket.
