Hi there,

I have been trying for days to install zeromq under fresh installations of Sage 5.8 on two different machines, one with Ubuntu 12.04.2 (32-bit), and the other with Ubuntu 12.10 (64-bit). I tried to install zeromq by means of:

./sage -i zeromq

as well as installing "sagemath-optional" from the repository. In all cases, the installation fails apparently because of this:

.....

checking alloca.h usability... no

checking alloca.h presence... yes

configure: WARNING: alloca.h: present but cannot be compiled

configure: WARNING: alloca.h: check for missing prerequisite headers?

configure: WARNING: alloca.h: see the Autoconf documentation

configure: WARNING: alloca.h: section "Present But Cannot Be Compiled"

configure: WARNING: alloca.h: proceeding with the compiler's result

......

(The full log is here.)

What's wrong? Can anybody help me?

Thanks, Andrea

PS. On one of the two machines, I also compiled gcc 4.7.2 (sage -f gcc) but it did not help at all.
