appears to work on Linux. I'll check on OSX too, then we'll see (building/running surf might need testing in particular).

comment:7

by the way, I see the following error messages on console:

[IPKernelApp] ERROR | No such comm target registered: jupyter.widget.version
// ** Could not find dynamic library: p_Procs_FieldZp.so (path /home/dima/Sage/sage-dev/local/bin/../libexec/singular/MOD:/home/dima/Sage/sage-dev/local/libexec/singular/MOD)
// ** Error message from system: /home/dima/Sage/sage-dev/local/bin/../libexec/singular/MOD/p_Procs_FieldZp.so: undefined symbol: omFreeToPageFault
// ** Singular will work properly, but much slower.

A dodgy macro [RS_CHECK_LIB(m, main) in configure.in leads to inability to build surf on OSX:

checking for main in -lm... no
configure: error: Sorry: can't link with library libm.\(a\|so\).

should be easy to fix...

That's a known issue upstream.

The problem can be solved with --disable-cups. But it still leads to trouble further down, because of a missing -ljpeg, which is not part of Sage.

shouldn't then surf be downgraded to experimental?

Replying to @dimpase:

Well, the package works, it's just that it has dependencies which are not in Sage. So I don't know what the policy is for that...

shouldn't an optional package be available on all sage-supported platforms?

For the record, rst2ipynb is also optional is not "available on all sage-supported platforms".

Because it depends on pandoc which is not part of Sage.
