[baconpaul]

Cool. I did adjust the windows.wt thing today

[tank-trax]

It didn't build the LV2 assets though
only the Surge.so plugin, no *.ttl files were created

[baconpaul]

OSError: target/lv2/Release/Surge.lv2/Surge.so: undefined symbol: cairo_xcb_surface_create

that's the problem

apt-get install cairo

maybe?

[baconpaul]

Or somehow get the cairo dll in your path consistently when the python runs.

[tank-trax]

I am pretty sure I have cairo installed. It never failed before.

As well it's completely freezing up Qtractor. So bad that I have to literally shut down the computer. Mind you it's a new build of Qtractor so not sure where the breakdown is. It does the same thing with Beatzille and Bazille. Have to reboot. Am commenting from another computer.

[tank-trax]

it freezes at DataPath is ~/Documents/Surge

[baconpaul]

Can you show me the full output? Also are you at head? I thought I commented that print out last night.

[tank-trax]

I tried a clean git clone and same issue

git log
commit 0b1caaf5efdeb32cb0489489e31806bd78f10cab

[baconpaul]

hmm well I was able to build it on ubuntu. Wonder what the difference is! Let me tag in @jpcima and @falkTX to see if they have an idea?

[tank-trax]

it must be some local issue. I have some weirdness happen like where I had to reinstall stuff because basic commands were not working... will check later

[tank-trax]

I just installed

libcairo-ocaml
libcairo-ocaml-dev
libenchant-dev
libglade2-dev
libgtkspell-dev
liblablgtk2-ocaml
liblablgtk2-ocaml-dev
liblablgtk2-ocaml-doc

still fails

[tank-trax]

how can I build previous commit?

[tank-trax]

why is it lurking in my conda folder???

    return self._dlltype(name)
  File "/home/studio/miniconda2/lib/python2.7/ctypes/__init__.py", line 366, in __init__

[tank-trax]

I think I found it

[tank-trax]

I set up my environment to use conda activate and it was set up to be enabled at log in

ran conda deactivate to exit the python shell and it built

sorry :-)

[baconpaul]

Oh yeah I should have thought of that! Your python environment needs to be able to find Cairo.
Glad you got it sorted!
