Thanks! So based on that I am going to try to create my own R buildpack using Vulcan, with --with-cairo --with-libpng build switches. This seems like something way out of my league but I'll give it shot.

You can also use vagrant to simulate the heroku environment and package
things up that way. I am actually almost done with just that step myself.

I'm trying to follow the instructions here to get a baseline R buildpack but I'm missing something big.

https://github.com/virtualstaticvoid/heroku-buildpack-r/blob/master/support/README.md

I downloaded the vulcan-build and build-r scripts into their own folder, and ran the vulcan create command to create Heroku build server.

bash vulcan-build.sh
tar: features.h: Cannot stat: No such file or directory
tar: Error exit delayed from previous errors.
Uploading source package... done
Building with: ./build-r 2.15.1

Downloading build artifacts to: /tmp/build.tgz

shill:R shill$

Where should I find the features.h file?

from heroku-buildpack-r.

Sorry for my ineptitude - all the files needed are in the /support folder.

from heroku-buildpack-r.

Would anyone be able to confirm that I need to add --with-cairo --with-libpng to line 58 to enable PNG support?

./configure --prefix=$prefix --without-x --with-cairo --with-libpng --enable-R-shlib && make && make install

from heroku-buildpack-r.

That is accurate, to the best of my knowledge.

Ok ok so I am back here: noahhl/rookonheroku#1 (comment)

I have the same question as the next commentator -
noahhl/rookonheroku#1 (comment)

how do I actually execute the commands referenced in that comment? As written they don't seem to be actual commands.

curl fontconfig

just returns an error. Could the enlightened educate the dumb please?

from heroku-buildpack-r.

I am not deeply familiar with vulcan building, but in a vagrant box you can
just apt-get the supporting tools (like curl) to do this kind of thing.
Curl is a linux library for pulling resources from elsewhere, and you need
it to exist on your system before it will run. I am working on literally
this exact problem right now (I am the owner of the stackoverflow thread
you mentioned) and I will keep you appraised.

Awesome thanks.

from heroku-buildpack-r.

Sorry for the late response... I've tried building with cairo support without much success (was requested in issue #8).

I found this thread How to get R to compile with PNG support on R devel that initially suggests it isn't possible on a headless server.

you need an X11 server because that is where the font metrics come from or else no png for you.

But further down they got it right by installing libpango.

I finally got it working. After mucking around in the R configure file a bit and trying out some of the different tests, as well as comparing a working system with our broken system, I realized that pkg-config --exists pangocairo was working on the good system and not working on the broken system. So I installed libpango1.0-dev, and now R picks up the cairo package.

I expect libpango will need to be installed from source though.

I'm a bit pressed for time at the moment, but will be happy give it a go next week.

from heroku-buildpack-r.

Great, thanks. I'm happy to try it out in the meantime, inexpert though I be. Where would we get libpango source from? Should I follow the Fortran example for compiling and including a dependency by source?

It suggests fontconfig and pixman are pre-requisites for cairo.

from heroku-buildpack-r.

If it is helpful, this is the build script I am working with right now. It
runs on a vagrant box that looks like heroku (which you can find online).
It currently fails to recognize cairo on the R build step, though.

I'm not certain this is helpful, but here is a node.js buidpack with cairo. There's some notes that might be useful about issues with getting cairo to build.

https://github.com/mojodna/heroku-buildpack-nodejs#cairo

(my stack is multipack node and R, but I think R needs to compile with cairo so I am doubtful it is helpful - compiling now).

In the notes, specifically

heroku/vulcan#20

"vulcan issue 20 contains information about how to build the binaries (more or less). Cairo was built by hand by using heroku run bash, as I couldn't get vulcan to correctly use the pixman and freetype dependencies when building. pixman and freetype were manually placed in /app/vendor and added to CPATH, CPPATH, and LIBRARY_PATH."

from heroku-buildpack-r.

So, of course that didn't solve my R build, because I need cairo installed before R builds. I did confirm that buildpack https://github.com/mojodna/heroku-buildpack-nodejs#cairo installs cairo

~ $ dpkg -S cairo

I don't know what to do next because I don't know how to solve the problem that R is built on Vulcan and apparently Vulcan won't build cairo.

from heroku-buildpack-r.

I had a thought - anyone know if it is possible to create a multipack of Vulcan and the node+Cairo package. That might do it to create the right environment for R. But I don't know how to create a Vulcan buildpack to use for this purpose.

from heroku-buildpack-r.

Here's a build pack with just Cairo, for the non-nodester.

https://github.com/rumblelabs/heroku-buildpack-cairo

from heroku-buildpack-r.

Are we sure Heroku does not come with cairo? I set up a clean vulcan build server and ran:

~ $

Is it possible that we just need to tell R where to find it? Anyone know how to do that?

from heroku-buildpack-r.

Heroku does come with Cairo (dpkg -l | grep cairo for the version), but it doesn't include the development package (so you can't compile against it, since there are no headers). It's also an old version of Cairo (which matters for node-canvas, but may not for your cases).

The Cairo lib you want to actually be linking against / loading is in /app/vendor/cairo/lib (/usr/lib*/ contains the Heroku/Debian-provided, older lib). This is where CPATH, CPPPATH, LD_LIBRARY_PATH, etc. come in.

+1 on building via Vagrant; some things need more memory than are available on a dyno. In this case, you could even take the Heroku-esque image, apt-get install libcairo2-dev (and possibly libpixman-1-0-dev), build against system Cairo, and then drop the resulting R binary on a Heroku dyno w/o needing add'l Cairo/pixman libraries (i.e. those provided by the buildpack).

from heroku-buildpack-r.

Ok, I'm making some progress. I've been testing locally using vagrant and the heroku basebox.

I've managed to build pixman-0.29.4 and cairo-1.9.14 from source successfully, but when running configure on R-1.15.1 sources, it's saying that it's found cairo but that it doesn't work:

$ ./configure --prefix=$vendordir/R --with-libpng --with-cairo --enable-R-shlib
...
checking whether pkg-config knows about cairo and pango... no
checking whether pkg-config knows about cairo... yes
checking whether cairo is >= 1.2 and works... no

Trying to figure out why this is happening.

Is it too early to Fedex you a bottle of scotch for your efforts?

from heroku-buildpack-r.

Check your PKG_CONFIG_PATH. It's probably not finding the right Cairo lib.

Ok, I'm making some progress. I've been testing locally using vagrant
and the heroku basebox.
I've managed to build pixman-0.29.4 and cairo-1.9.14 from source
successfully, but when running configure on R-1.15.1 sources, it's saying
that it's found cairo but that it doesn't work:

$ ./configure --prefix=$vendordir/R --with-libpng --with-cairo
--enable-R-shlib
...
checking whether pkg-config knows about cairo and pango... no
checking whether pkg-config knows about cairo... yes
checking whether cairo is >= 1.2 and works... no

Trying to figure out why this is happening.

Good luck! I'm getting defeated just installing rails to get the vagrant bundle to work. I don't know much Ruby.

If you are on Linux, I think it is just sudo apt-get install vagrant. If
you are not on Linux, I strongly recommend it for this sort of work.

I think I did it. I will test a bit more tomorrow to be sure, but I just
made a simple png in the vagrant box off my built code.

I got it working by cheating and installing libcairo2-dev (sudo apt-get install libcairo2-dev). Now to figure out the difference between the source build and the packaged one.

from heroku-buildpack-r.

Fantastic! If anyone wants to share an R buildpack with PNG support for me to test in my multipack environment, I'll jump right on it.

from heroku-buildpack-r.

Unfortunately I still need to have built from source version to create the build pack, since cairo and dependencies need to be in the /app/vendor directory for it to work.

from heroku-buildpack-r.

I am uploading a tarball called r-test-build.tar.gz to the rcairo bucket on
AWS. SImon: if you could fork the r buildpack, change the binary and
bucket names in bin compile, and test with that, that would be super.

Note: this does not have pango for ideal font support, but we can test that
later. FYI in case you see unexpected font behaviors. Also, for those
that need a dumb fix while we are testing this: try calling bitmap()
instead of png(). It is uglier, but works in the base buildpack.

I'm going out for a few hours - if anyone wants me to fork the buildpack and change the S3 paths in the compile file I can do that. Incidentally, I didn't find that bitmap() worked. I'm using ggplot2 and wordcloud - not sure if they require PNG. I need to find a better way to debug my R scripts - they fail silently behind a node API wrapper of Rserve.

Weird. I use lattice and bitmap is fine; must be ggplot. I am using rpy
and have the same debugging issues; I have to test everything in studio
first.

W: Not using locking for read only lock file /var/lib/dpkg/lock
E: Unable to write to /var/cache/apt/

Should I assume that is on your vagrant box? I have been procrastinating setting up vulcan because I didn't really understand what I was doing yet.

@metalaureate https://github.com/metalaureate Yes using vagrant. I
find it much easier to use this initially, primarily because bandwidth is
an issue here in South Africa, but also it makes debugging easier.

I found what appears to be the differences between the source and package
builds, so I'll carry on today in trying to get a source build done. After
that I'll move over to using vulcan for the final build and packaging of
the buildpack.

I've created the png_support branch with the updated build script. Also, the updated binaries are on S3, so you can provision your heroku instance as follows to get this version:

heroku create --stack cedar --buildpack http://github.com/virtualstaticvoid/heroku-buildpack-r.git#png_support

from heroku-buildpack-r.

Testing it now

from heroku-buildpack-r.

In my tests, running capabilities() reports that PNG and CAIRO are supported now, however failed to run png() with an error message to do with X11.

I think it may still need pango to work properly so I'll carry on to get this included too. Also, pango needs updated versions of pixman-0.3.0 and cairo-1.12.14 so I'll update the build accordingly.

from heroku-buildpack-r.

Mine worked without pan go, I believe. Are you calling PNG(type='cairo')
or cairopng or something else?

I did not patch GCC headers, I think; I do not recall why I skipped that.
If you are using my tar ball, that is probably the reason. Same question:
are you calling PNG() or PNG(type='cairo')?

Apologies - that was to @virtualstaticvoid

What's weird is that install.packages("RJSONIO"); works in a R console on heroku, but errors out when init.r runs (error posted above)

from heroku-buildpack-r.

@virtualstaticvoid @bwarren2

The following generates a file, but I am having some kind of newbie failure to get it to serve from my web server so that I can see what it looks like.

png(filename='public/img/test_r_graphics.png',type="cairo-png");plot(r);dev.off();

You should be able to pull down a file with a curl from the address hosting
your heroku instance. As for library failures, this is all using the new
branch? What are the wordcloud dependencies?

Looking into @metalaureate compile problem with RJSONIO

Thank you - sorry this is such a toilsome project. I'm so grateful to the both of you for working on this.

Ok, it seems that the "clean up" to make the build-pack smaller deleted more than it should have.
I've uploaded the corrected binary to S3, so you can give it a try again.

Awesome possum, @virtualstaticvoid. I am obviously just hacking my way
around with bad style; mind if I pick your brain to get better?

How did you identify the set of dependencies to install? I tried to
install Cairo, failed, identified something that was required, failed, and
did this until giving up and apt-getting libpng and others. By contrast,
you managed to figure out the finite list of things to build, and did not
require apt get. What is your secret?

What are shopt and pushd doing in your cleanup? I am unfamiliar with
them.

How is R detecting your installed things without flags? I do not
understand well how OSes manage these sorts of things.

Many thanks for your diligent efforts; they are much appreciated.

Running configure and looking at the config.log file usually helps. Also, running pkg-config --list-all to get the list of known libraries and for each library, running pkg-config --libs <lib_name> shows the paths to the library binaries, pkg-config --cflags <lib_name> the compiler flags and pkg-config --exists <lib_name> --print-errors checks that the library exists (this is what configure does).

Also, by building with the dependencies via apt-get and then without and comparing the outputs provides clues to what is missing. Vagrant helps because you can start again with a clean VM each time. E.g. This was how I figured out that DirectFB was one of the missing dependencies when building cairo.

Also, piping command outputs to file, so you can compare them, makes it easy to see the differences.

As for shopt and pushd\popd checkout any decent guide to bash, such as Bash Guide for Beginners.

Many thanks Chris; I feel bad pestering people over these sorts of tasks,
so I want to learn the methods as much as possible. You have been a life
saver.
