Documentation on memory and storage requirements missing

[ynikitenko]

When I run kiwix-build libzim (I actually wanted to build kiwix-desktop, but stumbled upon this one), test libzim test failed.

It was shown that cluster test failed. It turned out that /tmp was full because of 4Gb folder /tmp/test_cluster_JBOdRV . I deleted this directory (maybe there was data from several failed installations, when I had low bandwidth). When I rerun kiwix-build, it creates a new test_cluster tmp directory and fills it 4 Gb pretty quick. No surprise the test fails after that. I think 4Gb for a test is pretty much, with all due respect to libzim (or it must be written explicitly in requirements).

It's also a pity that the reason of failure is not printed (I discovered that by chance, when tmp was reported full when I ran another command).

I'm using a laptop with Fedora Core 29, if that matters.

P.S. I finally found that this problem exists and is reported (openzim/libzim#147 (comment)). I'm very sure that if large memory is a requirement for kiwix, it must be written explicitly on its page (and how to skip that, because users don't necessarily want their programs tested).
I'd make this a documentation bug, but can't categorize it here, and please don't close that until the docs (README) are fixed.

export SKIP_BIG_MEMORY_TEST=1

solves the problem, but it should be documented as well.

Yes, kind of duplicate of #398

I have updated the documentation of libzim:
openzim/libzim@2e98509

@kelson42 - yes, this was a duplicate, but the original one was closed unfixed. Great that you finally fixed that, thanks!
