Prepare R and libraries for Ubuntu 20.04

Known problems :

• some libs (used by R or its packages) are no more available in the Debian packages :
  • libpng12
  • libgfortran
    • gcc-6-base

Diagnose

Run TXM’s R via terminal:

cd /usr/lib/TXM-0.8.1/plugins/org.txm.statsengine.r.core.linux_1.0.0.*/res/linux64/bin
./R

Solution 1

Ubuntu 20.04: ship the missing libraries in TXM R lib directory : /usr/lib/TXM-0.8.1/plugins/org.txm.statsengine.r.core.linux_1.0.0.*/res/linux64/lib

Ubuntu 16.04:

• this new libs will broke the dependancies ->remove the libpng12 and libgfortran files of the lib directory
• if installed with the deb installer remove /usr/lib/TXM-0.8.1/plugins/org.txm.statsengine.r.core.linux_1.0.0.*/res/linux64/lib/libgfortran.so.3
• if installed with an update remove ~/.TXM-0.8.1/plugins/org.txm.statsengine.r.core.linux_1.0.0.*/res/linux64/lib/libgfortran.so.3

  • relates #3086
  • parent #2845 (closed)

added priority::high r type::task + 1 deleted label

changed milestone to %TXM 0.8.2

I tried the solution 1 (ubuntu 16.04) :

No libfortran found in /usr/lib/TXM-0.8.1/plugins/org.txm.statsengine.r.core.linux_1.0.0.202006290905/res/linux64/lib

libpng12.so.0 removed.

The specificity and CA still don’t work, with the same errors :

impossible de trouver la fonction "phyper" for Specificities
** Erreur R : "Error : le chargement du package ou de l'espace de noms a échoué pour ‘FactoMineR’" for CA
