Ran into a problem today with revCreateXMLTreeFromFile() not working. It's ok on the LC6 commercial build, so I'm guessing that my 64-bit engine build isn't linking up properly with some of the thirdparty libraries.

Hmmmm - a couple of questions that might help track down the problem...

Is the external being built? (Check the _build/linux/x86_64 folder)...

Is the external being loaded on startup of the IDE? (Check 'the externals of stack "home"')...

If it is not being built, then that will be the issue...

If it is not being loaded by the IDE it could be a glitch in the 'Clone and Run' stuff I added, not properly recognising 64-bit Linux (although I thought I wrote it generically enough to work there).

Seem to be having problems with some of the prebuilts:

Here's what's in prebuilt (not prebuilt/linux-x86_64):

Here's what I've got in _build/linux/x86_64/debug up to this point:

So it appears that my environment isn't getting set up properly.

are you running git submodule update after checking out the branch with those files?

Yes - this sounds like the prebuilt submodule is still pointing at the commit for master, rather than the commit for develop.

@Monte- yes, thanks. Brain freeze - I did a "pull --recurse-submodules" instead of a pull and a "submodule update". That and merging my fix-glib-errors branch in the thirdparty directory did the trick.

@mwieder: This reminded me there was a pending pull request on thirdparty module from you... Now pulled in

! libxml is getting built if you "make all" but not if you "make development". A make development just happily ignores libxml and then, of course, the xml functions don't work.
The change would be in the main Makefile, but I'm hesitant to issue a pull request, not knowing what other changes might be in the queue.
