It is link time dependency, so it would be normal do include 'devel'
package and JDK is 'devel'. But I agree, it is a bit of overkill here.

IMHO this is the way to go.

The split between *-jre and *-jre-base is just for this – -jre is the
'default' JRE (only one installed) and -jre-base is the actual JRE, but
without anything conflicting with another JRE implementation

/usr/lib64/jvm/java symlink

[Tomasz Pala]

I'm trying to compile qgis using gdal:

/usr/bin/ld: warning: libjvm.so, needed by 
/usr/lib64/gcc/x86_64-pld-linux/5.3.0/../../../../lib64/libgdal.so, not found 
(try using -rpath or -rpath-link)

gdal.rpm requires libjvm.so, so I've installed the same java version it was
compiled with, i.e. openjdk8-jre-base; however libgdal.so uses
/usr/lib64/jvm/java path, which exists in openjdk8-jdk:
/usr/lib64/jvm/java -> openjdk8-8u72.b15
JRE contains only
openjdk8-jre -> openjdk8-8u72.b15/jre
symlink.

Something needs to be fixed: either
- gdal should require JDK package - overkill, or
- symlink should be moved to JRE, or
- symlink should be moved to some java-default package and this one
  should be required by gdal,
- or anything you can propose, I'm not familiar with java.


The one suggestion I might make, is changing java symlink to:

/usr/lib64/jvm/java -> openjdk8-jre (without version/build/whatever this is)

to make sure, that JRE (e.g. openjdk8-jre) points to the same place in case
multiple versions are installed.
