Test-suite on Ubuntu 18.04 of 7.0.7 returns two fails, questions about use

[briligg]

After a new install of IM 7.0.7-37 Q16HDRI , I ran "make check". The results had 2 fails:

FAIL: tests/wandtest.tap 1
FAIL: Magick++/demo/demos.tap 6

I have opened an issue on the GitHub repo, as the read-out requested - it's here, and includes the test-suite.log - https://github.com/ImageMagick/ImageMagick/issues/1161

What I'm wondering here is, can I go ahead and use IM?

It seems to be missing a shared library, actually. I just tried "identify -version" and got an error:

Code: Select all

magick: error while loading shared libraries: libMagickCore-7.Q16HDRI.so.6: cannot open shared object file: No such file or directory

Should I add that to the bug report? How can I get that library?

EDIT - Scratch the last part, about that shared library error. I just needed to run

Code: Select all

sudo ldconfig /usr/local/lib

, which the instructions on installing from source said might be necessary. My bad.

The main command for IM v7 is "magick", not "convert" or "identify". (However, your build might have installed these as symbolic links.)

I suggest you try "magick identify -version". If that complains it can't load a library, then there was a build problem. What does config.log say about it?

[briligg]

Yeah, I just caught that the instructions for installing from source said it might be necessary to run that extra command i just added to the original post.

I am now running make check again.

Before this install Ubuntu expected me to not use 'magick'. It would say the command wasn't recognized if I did that. I got used to that.

Okay, the test-suite still fails twice, on the same tests.

Config.log is pretty long. Shall i post it somewhere so you can look at it? Is there something in particular in it i can post here?

Delegates (built-in):

You have no delegates in your install. How did you install? If from source, you must install all your needed delegates first. If from binary, then the delegates most used should come with it. Typically, you need delegates for JPG, TIFF, PNG as well as fontconfig and free type and lcms2 at a minimum as well as ghostscript and rsvp or inkscape for vector files.

See http://www.imagemagick.org/download/delegates/

Here are my delegates, though you do not need all of them.

libtiff.so.5 -> libtiff.so.5.3.0

Oh, just saw your latest reply. Let me work through that.

[briligg]

Do I need to uninstall it then, or can I now install the delegates after the fact?

Alright, you said i must install them first, so i'm taking it i should uninstall IM, get the delegates i need, and then reinstall it.

[fmw42]

No, I do not think you need to uninstall ImageMagick. You can just re-install after loading your delegates. Or you can recompile pointing to where you put your delegates. I am not an expert on this, but see the configure section of https://www.imagemagick.org/script/adva ... lation.php

Some help with installing delegates on Ubuntu was in this answer - https://askubuntu.com/a/746195/364597 - but it is outdated now. There still is no TIFF delegate, and many other gaps. This is proving difficult, i've been at it all day.

I am going to work on it for another half-day or so, and if there isn't a break on this, i'll roll back to the version that comes with Ubuntu 18.04, and start working with .mpc files. I'll probably start working with .mpc files anyhow, but this seemed to hold promise for speeding up processing, since Snibgo said v. 7 could probably process a grayscale image using 2 byte processing instead of 8.

This issue has now been completely resolved with an answer to my question about it on AskUbuntu.SE, here - https://askubuntu.com/a/1042482/364597.
