I am attempting to install the latest PostGIS 3.0.x on CentOS 8, with no luck.
I don't think anyone is running PostGIS on RHEL 8 or CentOS 8, I can't understand why not. It does not seem possible to install.
I have successfully installed Postgres 12.0 by disabling the RHEL AppStream
Steps I took installing postgres 12 on CentOS 8:
1)
#dnf install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
2)
#dnf --disablerepo AppStream install postgresql12
#dnf --disablerepo AppStream install postgresql12-server
I am attempting now to install PostGIS.
#dnf list --available | grep postgis30
I see that postgis30_96 is the latest offered (as listed below):
postgis30_96.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-client.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-client-debuginfo.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-debuginfo.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-devel.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-docs.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-gui.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-gui-debuginfo.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-utils.x86_64 3.0.0alpha4-6.rhel8 pgdg96
When I try to install with the following command:
#dnf install postgis30_96
I get these errors:
Last metadata expiration check: 1:22:58 ago on Tue 15 Oct 2019 08:25:10 PM UTC.
Error:
Problem: cannot install the best candidate for the job
- nothing provides hdf5 needed by postgis30_96-3.0.0alpha4-6.rhel8.x86_64
- nothing provides xerces-c needed by postgis30_96-3.0.0alpha4-6.rhel8.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
I look for xerces-c, and nothing is returned:
#dnf list --available | grep xerces-c
Where do I get xerces-c to install?
I look to see if hdf5 is available to install (dependency)
#dnf list --available | grep hdf5
and nothing is returned. How do I satisfy these dependencies, so that PostGIS will install?
I goto the hdf5 website, download the source and it's a BIG FAT MESS. The build/install instructions do not work - the code is out of sync with the install instructions.
I check the hdf5 website and find another set of build/install instructions, and they too are out of sync with the latest code base. I don't know which way is up with this project, if it's a zombie project out there on the web, seemingly alive, but nobody's home.
How do I get hdf5 easily onto my system and xerces-c so that nothing existing gets mucked up? I would prefer to install these through any somewhat sanctioned CentOS 8 package repo using dnf.
I can't log this issue on the PostGIS ticket tracking system. Logging a ticket there requires an OSGEO ID, and when I request a 'mantra' to get started, nothing is returned, no response,
OSGEO is yet another zombie project, nobody's home. https://www.osgeo.org/community/getting-started-osgeo/osgeo_userid/
Please respond only if you have actually done this yourself on a CentOS 8 machine or VM, while I appreciate suggestions, pointers or imaginations from others, it pollutes r/postgis reddit with misinformation, non-working solutions, and not only wastes my time with dead ends, but also the time of others.
Someone else inevitably comes along with the same problems and is misguided with these those that are well-intentioned, but provide incorrect or incomplete information.
The
postgis30_96
packages are for Postgres 9.6. You needpostgis30_12
for Postgres 12.These packages are definitely in the repo, so if your
dnf list
isn't seeing them, it may be an instance of a known issue in which "yum/dnf refuse to find/install many packages from PGDG repository on RHEL8".As a workaround, the Postgres Yum Howto recommends this installation procedure:
