Hi Guys,

I tried use LightXML on Ubuntu 16.04, but I got an error:

ERROR: error compiling call: could not load library "libxml2"

Can You help me?

Thanks.

I tried sudo apt-get install libxml2, but I got answer from ubuntu:

libxml2 is already the newest version (2.9.3+dfsg 1-1ubuntu0.1).
libxml2 is tagged as manually installed.

But from julia I got same answer:

ERROR: error compiling call: could not load library "libxml2"

You might need the -dev version to get a plain "libxml2.so" in addition to the version with an soname in it. I thought Julia should be able to find the soname versions too, but maybe not?

Thanks,

after installing

sudo apt-get install libxml2-dev

is LightXML fully working.

I have another question: Why this dependency didn't resolved automatically by Pkg.add("LightXML") ?

Could you file an issue against LightXML.jl? It should be able to
install the package automatically, or could even work without it.
