Indicate that iolib requires compiling libfixposix

[futuro]

This doesn't come up when you (ql:quickload :iolib), but it will fail quickloading other libraries, such as dbus, complaining about a missing lfp.h file.

Can this be stated explicitly in the iolib quickload process? Or perhaps the Readme?

[sionescu]

I'll add something in the README file.

[lokedhs]

This does not seem to have been fixed yet. I checked the current Quicklisp version (iolib-20151218-git) and neither the README nor the files in doc/ mentions libfixposix at all.

To make things worse, when trying to ql:quickload the library, there is nothing in the error message that suggests that libfixposix may be the problem. Here's the full output from an SBCL session where I try to load iolib:

("iolib")

Unless you know about libfixposix it's going to be a lot of work figuring out what's wrong.

[sionescu]

I added a mention in the IOlib and Libfixposix README files. More than this I'm not sure what to do.

[lokedhs]

Would it make sense to include the libfixposix source code in the iolib distribution itself, and have it compiled if it's not already available on the host?

[fourier]

I would vote for @lokedhs proposal. The problem is then some other package loadable from quicklisp depends on iolib and therefore fail to compile.
