<div dir="ltr">Greetings. I'm not quite sure where to post this question. I have been porting Kenichi Asai's OSX-based Universe library to ubuntu and have run into an opam error. Trolling around the internet has not led to a solution. Kenichi's installation instructions were expressed in terms of macports + opam:<ul style="color:rgb(0,0,0);font-family:Times;font-size:medium"><li><pre>sudo port install cairo +x11
sudo port install gtk2 +x11
sudo port install libgnomecanvas
sudo port install pkgconfig
opam install ocamlfind
opam install conf-gnomecanvas
opam install lablgtk
</pre></li><li>Install OCamlMakefile.<pre>opam install ocaml-makefile
</pre></li></ul><div>I have followed these on ubuntu using apt-get, I believe successfully, until I get to the following. Any hints greatly appreciated. - Bob Muller</div><div>-------------------------------- <br><div><div>vagrant@vagrant-ubuntu-trusty-32:/usr/bin$ sudo opam install conf-gnomecanvas --verbose</div><div>The following actions will be performed:</div><div> - install conf-gnomecanvas.2</div><div>=== 1 to install ===</div><div><br></div><div>=-=- Synchronizing package archives -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=</div><div><br></div><div>=-=- Installing packages =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=</div><div>Building conf-gnomecanvas.2:</div><div> pkg-config libgnomecanvas-2.0</div><div>[ERROR] The compilation of conf-gnomecanvas.2 failed.</div><div>Removing conf-gnomecanvas.2.</div><div> Nothing to do.</div><div><br></div><div><br></div><div>#=== ERROR while installing conf-gnomecanvas.2 ================================#</div><div># opam-version 1.2.0</div><div># os linux</div><div># command pkg-config libgnomecanvas-2.0</div><div># path /home/vagrant/.opam/4.01.0/build/conf-gnomecanvas.2</div><div># compiler 4.01.0</div><div># exit-code 1</div><div># env-file /home/vagrant/.opam/4.01.0/build/conf-gnomecanvas.2/conf-gnomecanvas-23548-58c514.env</div><div># stdout-file /home/vagrant/.opam/4.01.0/build/conf-gnomecanvas.2/conf-gnomecanvas-23548-58c514.out</div><div># stderr-file /home/vagrant/.opam/4.01.0/build/conf-gnomecanvas.2/conf-gnomecanvas-23548-58c514.err</div><div><br></div><div>'opam install conf-gnomecanvas --verbose' failed.</div><div>vagrant@vagrant-ubuntu-trusty-32:/usr/bin$ </div></div><div><br></div></div></div>
