Issue Installing PRESTO Python Packages in Python3.9 on RHEL 8 about presto

[scottransom]

Looks like the PGPLOT that is installed is statically compiled. I highly recommend using a pre-compiled PGPLOT package if at all possible. It definitely needs to be dynamically compliled. If you are doing the compiling yourself, I can probably help with the missing steps.

So I did do a compile via Redhat, but that resulted in compile issues for PRESTO as it couldn't find where those directories were (because unlike Ubuntu, it scatters things rather than keeping them together).

Have you had any luck getting it compiled with the pgplot5 that RedHat8 has?

No, I use pre-compiled packages on the various Linux machines that I use (Ubuntu for personal ones and RHEL at work, although it is RHEL6 and 7 there, and 8 is coming for us soon). But the RHEL packages that are available seem to work out of the box (and they have all the shared libraries in them). In fact, I just noticed that I've had my PGPLOT_DIR environment variable set incorrectly on my RHEL7 workstation and PRESTO is still working and finding everything! On my other, older, RHEL machine I have PGPLOT_DIR set to /usr/lib64/pgplot.

So after talking with Nate, the conclusion is that if the following change is made to the Makefile, we can compile it with the pre-compiled packages for pgplot:

PGPLOTINC = -I/usr/include
PGPLOTLINK = -L/usr/lib64 -lcpgplot -lpgplot $(X11LINK) $(PNGLINK)

That gets everything linked correctly in RHEL8. ^_^

That's good to know! So that's only a minor tweak from what is in the current Makefile.
