            Bug ID: 14976
           Summary: Ghostscript package can not process pdf files anymore
           Product: buildroot
           Version: 2022.02
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
          Assignee: unassigned@buildroot.uclibc.org

  Target Milestone: ---

Dear Buildroot Dev Team,

thanks for the great work in the first place!

I am facing an issue with the Ghostscript package that is available in
buildroot. Starting with Version 2022.02 I am not able to process PDF files
anymore. I was already in contact with the Ghostscript developers, and we found
out that this has to do with the added compile option "--without-pdf" as the
version was updated to 9.55.0
(https://github.com/buildroot/buildroot/commit/7a4944569ce83b0b7b0cabd6e8aa184b8cb72a22).
They changed how PDF files are processed and did a greater rework, but adding
this above mentioned option totally disables the PDF feature (which is crucial
for example when driverless printing via Ghostscript is used). I think this is
not a generally wanted option. They also offered help when further need is
required to work out the proper compile options for the make settings within
buildroot.

--- Comment #1 from Lars <lars.george@biotronik.com> ---
I digged into the problem a little bit and got a fix for myself. First of all I
patched the mk file of the Ghostscript package:

 define GHOSTSCRIPT_REMOVE_LIBS
        rm -rf $(@D)/freetype $(@D)/ijs $(@D)/jbig2dec $(@D)/jpeg \
-               $(@D)/lcms2mt $(@D)/libpng $(@D)/openjpeg $(@D)/tiff \
+               $(@D)/lcms2mt $(@D)/libpng $(@D)/tiff \
                $(@D)/zlib
 endef
 GHOSTSCRIPT_POST_PATCH_HOOKS += GHOSTSCRIPT_REMOVE_LIBS
@@ -43,7 +43,7 @@
        --enable-freetype \
        --disable-gtk \
        --without-libpaper \
-       --without-pdf \
+       --with-pdf \
        --with-system-libtiff

 ifeq ($(BR2_PACKAGE_JBIG2DEC),y)


Furthermore I do need to have the following BR packages:
- BR2_PACKAGE_JBIG2DEC
- BR2_PACKAGE_OPENJPEG
