Description (last modified by )
I would like to teach first-year students how to use QEPCAD to solve systems of rational inequalities (example).
sage-6.2.ova displays the qepcad help with qepcad?, but it cannot be used:
qepcad('(E x)[a x + b > 0]', vars='(a,b,x)')
Traceback (click to the left of this block for traceback)
...
RuntimeError: Unable to start QEPCAD

Same error at https://cloud.sagemath.com/, see this sage-cloud thread.

The inclusion procedure says that qepcad needs to become an "optional package" first, and I assume that the current qepcad-1.50.spkg has similar problems as the 1.54 spkg from #10224.
So please close this ticket as invalid for now. (I don't have the rights to do this.)

@aapitzsch: This fails to build on Linux Mint 17 (≡ Ubuntu 14.04 LTS).

There are indeed too many systems on which this fails to install. Just got this error on my recent Gentoo Linux x86_64 system:
cd source; make opt "CCo=g++" "FLAGSo=-O4" "CCd=g++" "FLAGSd=-g" "MAKE=make " make[1]: Entering directory `/usr/local/src/sage-git/local/var/tmp/sage/build/qepcad-1.50/src/qesource/source' make[1]: *** No rule to make target `qepcad.a()', needed by `opt'. Stop. make[1]: Leaving directory `/usr/local/src/sage-git/local/var/tmp/sage/build/qepcad-1.50/src/qesource/source' make: *** [opt] Error 2 Error making QEPCADB

Btw., I get the same error at http://www.sagenb.org/. This should also be fixed. At http://sagecell.sagemath.org/ qepcad integration works!
