I've just built Sigil 2.4.2 on my Linux box. This time I used the bundled version of hunspell and didn't see any errors during the make and make install.
However, when I ran the testplugin (v0.2.0) as I usually do, on an epub2 file it produced 4 failures: "Failure - 4 Tests of Plugin Operations Failed". I've not seen such results after other builds.
The epub2 file had 'no problems found' under EPUBCheck 5.2.1.
Code:
Verifying selected basic plugin interface elements
bk.text_iter() works False
Listing manifested files...
Text/Section0001.xhtml
Text/chapter10.xhtml
bk.manifest_iter() works False
bk.spine_iter() works False
bk.other_iter() works False
reading a non-manifest book file works True
reading a specific OPF manifest id works True
writing to a specific OPF manifest id works True
Launcher Version 20250131
ePub Version 2.0
adding your own file to the manifest works True
basename to id mapping works True
deleting our added file works True
Next I tried an epub3 file (also 'nff' under EPUBCheck 5.2.1) and got the same results.
What is testplugin trying to tell me?
