Description Lars 2022-08-29 04:53:18 UTC

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.

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

 	--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
