Create image for building packages

[nuest]

I would like to install the sf library to Renjin, and one of the problems is the dependency on units:

• I would like to give it a go to create a Renjin package for units, but I am unsure how to start, as the only documentation I found is for packages with only R code: https://stackoverflow.com/questions/39333462/automated-porting-of-r-library-for-renjin/39342577#39342577
• But units includes C/C++ so it depends on Rcpp, which seems to be available, and units depends on a system library, which seems also the reason why it is not available pre-compiled, see error log in http://packages.renjin.org/package/org.renjin.cran/units/0.6-3/build/5

Steps:

• create a pom.xml as described here: https://github.com/perNyfelt/renjinSamplesAndTests/
• add C compiler dependency
• Install the package to local Maven repo from file
• load the package in R

See mjkallens answer to a similar question here. Basically what you do is

download the source code for the latest version of ctsmr
Unpack to a dir of choice
Add a pom.xml file that calls the renjin maven plugin
Add a Vagrant file similar to the one use to build the Renjin project itself to get the right versions of gcc etc. so that the renjin maven plugin can process the c and fortran sources.
start vagrant and run mvn clean install

That should also be possible in a container...

_Do I really net to get gcc-4.7 to work?

Looking at renjin's source code, it seems like it, 4.7 is hardcoded into the "gcc-bridge": https://github.com/bedatadriven/renjin/search?q=gcc-4.7&unscoped_q=gcc-4.7

Maybe installing from source is the only option...

• https://stackoverflow.com/questions/41412535/gcc-4-7-with-debian-8-jessie did not work, the base image for openjdk:11-jdk is Stretch
• Jessie images are only available for Java 7uNNN, see https://hub.docker.com/_/openjdk?tab=tags&page=2&name=jessie
• https://gcc.gnu.org/wiki/InstallingGCC
  • ftp://ftp.gwdg.de/pub/misc/gcc/releases/gcc-4.7.4/

With a Dockerfile based on ubuntu:xenial, I get further:

I did run library('org.renjin.cran:Rcpp') without error before running mvn clean install.

Maybe I need to configure the compilation process, cf. https://github.com/bedatadriven/libxml2/blob/master/pom.xml#L40

@akbertram any idea what might be going wrong here?

Still no idea how to progress here... asked on SO: https://stackoverflow.com/questions/58996151/rccp-h-not-found-in-renjin-when-compiling-package
