Dear Maintainer,

I tried coolreader, but it didn't start on my machine (Debian testing with few
unstalble packages). After install, I got this:

$ cr3 book.epub
2026/09/17 13:49:37.0504 WARN Changing log level from 3 to 1
Fatal Error: Cannot open font file(s) .ttf
Cannot work without font
Cannot init CREngine - exiting

strace showed this:

openat(AT_FDCWD, "/home/MYHOME/.cr3/fonts",
O_RDONLY|O_NONBLOCK|O_CLOEXEC|O_DIRECTORY) = -1 ENOENT (No such file or
directory)
openat(AT_FDCWD, "/usr/share/cr3/fonts",
O_RDONLY|O_NONBLOCK|O_CLOEXEC|O_DIRECTORY) = -1 ENOENT (No such file or
directory)

The /usr/share/cr3/fonts is not a part of the package

I hope it helps.

Petr

Please install at least one truetype font such as fonts-liberation,
fonts-dejavu-core or fonts-freefont-ttf.
After that try launch coolreader again, if ok I'll add dependency
to font the next upload. If not, please report back and we can dig
further.

I am also seeing the same error. fonts-dejavu-core, fonts-freefont-ttf, and
fonts-liberation were already installed, prior to installing coolreader.

We believe that the bug you reported is fixed in the latest version of
coolreader, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1148133@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.

Source: coolreader
Architecture: source
Version: 3.2.59+git20260725+ds-3
Distribution: unstable
Urgency: medium

Closes: 1148133
Changes:
 coolreader (3.2.59+git20260725+ds-3) unstable; urgency=medium
 .
   * Build with fontconfig support (Closes: #1148133): add libfontconfig1-dev to
     Build-Depends so CMake's find_package(FontConfig) succeeds and crengine is
     compiled with USE_FONTCONFIG=1. Without it the reader only scans ~/.cr3/fonts
     and /usr/share/cr3/fonts and aborts with "Cannot open font file(s) .ttf" even
     when Truetype fonts are installed.
   * Depend on fonts-liberation so a usable Truetype font is always present.
