[R-sig-Debian] So nearly there, but can't install rJava

As ever, I learn from this: I didn't know apt-file. Got it, installed it,
used it:

root at DebianAdvent:/home/chris/Downloads/gmp-6.1.2# apt-file search jni.h 
android-libnativehelper-dev: /usr/include/android/nativehelper/jni.h 
android-platform-frameworks-native-headers:
/usr/include/android/android/asset_manager_jni.h
android-platform-frameworks-native-headers:
/usr/include/android/android/native_window_jni.h
gcj-6-jdk: /usr/lib/gcc/x86_64-linux-gnu/6/include/jni.h 
gcj-6-jdk: /usr/lib/jvm/java-1.5.0-gcj-6-amd64/include/jni.h 
libavcodec-dev: /usr/include/x86_64-linux-gnu/libavcodec/jni.h 
libgluegen2-build-java: /usr/share/gluegen2/make/stub_includes/jni/jni.h 
openjdk-8-jdk-headless: /usr/lib/jvm/java-8-openjdk-amd64/include/jni.h 

I was 99% sure I already had that last installed. Sure enough: 

root at DebianAdvent:/home/chris/Downloads/gmp-6.1.2# apt-get install
openjdk-8-jdk-headless
Reading package lists... Done 
Building dependency tree 
Reading state information... Done 
openjdk-8-jdk-headless is already the newest version (8u181-b13-2~deb9u1). 
openjdk-8-jdk-headless set to manually installed. 
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. 

Anyone else got any ideas?

Java can be tricky and that is one of the reasons we have r-cran-rjava
prebuilt for you. It should resolve issues and work because other binary
packages depend on it.

Otherwise, as Johannes hinted, you need a JDK if you build with rJava from
CRAN source, and 'sudo R CMD javareconf' should work.  

I don't do much work on Debian stable so no concrete tips from me.

Install the full-blown jdk no just headless.

In the sources for rJava I have as a build-depends

   openjdk-10-jdk

which may of course be a virtual. At some point we had more than JDK
implementation.  See what you can find there.

I have not followed the discussion closely, so my
apologies if I am off-topic. But on Ubuntu 18.04 at
least you can run

  sudo apt install openjdk-11-jdk
  R CMD javareconf -e

and then in R

  install.packages("rJava")

should work.

kind regards
        Enrico

[R-sig-Debian] So nearly there, but can't install rJava

Thanks Dirk and Enrico,

First clarification: I'm in this mess because I'm trying to run R 3.5.2
within Debian stable (9/"sretch") using the stretch-cran35 repository.
That uses and provides r-api-35 but many of the packages depend upon r-api-3. 
As Johannes said a day or so back, the way around this is to use
install.packages() in R to get the packages you want. That leads you into quite
a lot of manual identification of dependencies and I worked through all the ones
I hit until I was left with the only packages I use that I can't install
sharing just one dependency: they all depend on rJava and I can't install
from the r-cran-rjava package in the stretch-cran35 repository because
that's one of the packages that depends on r-api-3.

I thought that installing the default java and jdk Debian packages and using R
CMD javareconf (as root) would set the right variables for
install.packages("rJava") to work but no go.  It fails with this
information:

checking Java support in R... present:
interpreter : '/usr/lib/jvm/default-java/jre/bin/java'
archiver    : '/usr/lib/jvm/default-java/bin/jar'
compiler    : '/usr/lib/jvm/default-java/bin/javac'
header prep.: '/usr/lib/jvm/default-java/bin/javah'
cpp flags   : ''
java libs   : ''
configure: error: One or more Java configuration variables are not set.
Make sure R is configured with full Java support (including JDK). Run
R CMD javareconf
as root to add Java support to R.

If you don't have root privileges, run
R CMD javareconf -e
to set all Java-related variables and then install rJava.

ERROR: configuration failed for package ?rJava?
* removing ?/usr/local/lib/R/site-library/rJava?

I think the problem may be options setting where R/rJava will look for Java so I
tried:
> options(java.home="/usr/lib/jvm/java-8-openjdk-amd64/")
> options("java.home")$java.home
[1] "/usr/lib/jvm/java-8-openjdk-amd64/"

but that doesn't change things. 

As far as I can see Debian is happy with the setup of java and javac:

root at DebianAdvent:/home/chris/Downloads/gmp-6.1.2# java -version
openjdk version "1.8.0_181"
OpenJDK Runtime Environment (build 1.8.0_181-8u181-b13-2~deb9u1-b13)
OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode)
root at DebianAdvent:/home/chris/Downloads/gmp-6.1.2# javac -version
javac 1.8.0_181
root at DebianAdvent:/home/chris/Downloads/gmp-6.1.2# update-alternatives
--config javac
There is only one alternative in link group javac (providing /usr/bin/javac):
/usr/lib/jvm/java-8-openjdk-amd64/bin/javac
Nothing to configure.
root at DebianAdvent:/home/chris/Downloads/gmp-6.1.2# update-alternatives
--config java
There is only one alternative in link group java (providing /usr/bin/java):
/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java
Nothing to configure.
root at DebianAdvent:/home/chris/Downloads/gmp-6.1.2# 

And I have the full jdk not just the headless version I can see the header
files:

root at DebianAdvent:/home/chris/Downloads/gmp-6.1.2# ls -lsart
/usr/lib/jvm/java-8-openjdk-amd64/include/
total 220
80 -rw-r--r-- 1 root root 78425 Oct 22 19:05 jvmti.h
 8 -rw-r--r-- 1 root root  4771 Oct 22 19:05 jvmticmlr.h
76 -rw-r--r-- 1 root root 74698 Oct 22 19:05 jni.h
 8 -rw-r--r-- 1 root root  7404 Oct 22 19:05 jdwpTransport.h
12 -rw-r--r-- 1 root root  9687 Oct 22 19:05 jawt.h
24 -rw-r--r-- 1 root root 21125 Oct 22 19:05 classfile_constants.h
 4 drwxr-xr-x 2 root root  4096 Jan 22 08:09 linux
 4 drwxr-xr-x 3 root root  4096 Jan 22 08:09 .
 4 drwxr-xr-x 8 root root  4096 Jan 22 12:55 ..
root at DebianAdvent:/home/chris/Downloads/gmp-6.1.2# 

But I can't reconfigure R for Java:

root at DebianAdvent:/home/chris/Downloads/gmp-6.1.2# R CMD javareconf
*** JAVA_HOME is not a valid path, ignoring
Java interpreter : /usr/lib/jvm/default-java/jre/bin/java
/usr/lib/R/bin/javareconf: 1: /usr/lib/R/bin/javareconf:
/usr/lib/jvm/default-java/jre/bin/java: not found

*** Java interpreter doesn't work properly.

root at DebianAdvent:/home/chris/Downloads/gmp-6.1.2# 

I hope this helps someone see something I can fix!

Tangential question: surely I'm not rare in running R 3.5.2 on Stretch am I?
Other tangential question: is there anything that can be done to fix the
r-api-3/r-api-3.5 issue.  You can see I'm no programmer or sysadmin but if
there is anything I can do to help ...?

TIA all,

Chris
