Description:
Hi,sorry to interrupt you,but when I invoke glpk() to solve my Linear Programing Problem,it complains:

error: glpk: not supported on this system
error: called from:
error: /usr/share/octave/3.2.3/m/optimization/glpk.m at line 549, column 32

BTW,I have glpk installed via AUR,and my LP problem is from the official manual without any modification:

c = [10, 6, 4]';
a = [ 1, 1, 1;
10, 4, 5;
2, 2, 6];
b = [100, 600, 300]';
lb = [0, 0, 0]';
ub = [];
ctype = "UUU";
vartype = "CCC";
s = -1;

param.msglev = 1;
param.itlim = 100;

[xmin, fmin, status, extra] = ...
glpk (c, a, b, lb, ub, ctype, vartype, s, param);

So,what's wrong with this?

Additional info:
* package version(s)
octave 3.2.3-3
glpk 4.43-1

In addition,I have pkgs miscellaneous-1.0.9 , optim-1.0.12 ,optiminterp-0.3.2 installed for octave.

Hopefully you could fix it,please.
This task depends upon

glpk is not supported in the octave version in the repos. To get this functionality working you probably need to recompile octave with glpk support (so just rebuild it on your machine with glpk installed).

If you think this is a widely used/needed functionality, please provide some more info on the function as it requires bringing in a new dependency.
I didn't look in the glpk function but is it much different from the fminbnd function (I think this just from looking at the example you provide, it may in fact be completely different, just a guess)?

Thank You For Your Reply.After compiling octave for almost 5 hours,I've to drop it ('cause I have to sleep,hoho).
