libxml check fails b/c libiconv is not getting included in list of linked libs #1199

Closed mcmire closed 9 years ago

Quick facts:

I am getting this error when attempting to install Nokogiri:

libxml2 is missing.  Please locate mkmf.log to investigate how it is failing.

Here is the mkmf.log output:

--------------------

So the error in this case appears to be misleading.

As you can see, when it checks whether libiconv is installed, the first check (without the -liconv flag) fails, but then the second one succeeds.

When have_func is then called to determine whether libxml is fully available, that check fails, as libiconv is being referenced inside of libxml. However doing so does not work, as the -liconv flag is not being passed to clang in this case.

Ideally, I believe have_iconv? should add libiconv to the list of libraries somehow so that subsequent commands properly include it.

Okay, I figured it out. Ruby 2.1.4 was already installed, but where apple-gcc42 had been brew linked. I unlinked it prior to installing Nokogiri. After keeping it unlinked, then completely removing Ruby 2.1.4 and re-installing it using Clang instead, I didn't have any problems re-installing Nokogiri.

Is there anything we can learn from this, that we should add to the installation tutorial?
