[ptxdist] Make libcups and libcupsimage get installed by my ptxdist cups.make

[ptxdist] Make libcups and libcupsimage get installed by my ptxdist cups.make

[David Thomas]

Hello,

I am trying to compile cups and ghostscript for the phycore-am335x target using ptxdist.

Most of the work is done, and both packages compile and build successfully. The problem I have is that I cannot get ghostscript to create gstoraster which is needed for cups to work with non-Postscript printers.

I already know that ghostscript requires libcups and libcupsimage from the cups package. I am trying to install them with:

	# Install the libraries.
	@$(call install_lib, cups, 0, 0, 0644, libcups)
	@$(call install_lib, cups, 0, 0, 0644, libcupsimage)

To try and help install_lib find the right packages, I have added these commands into the makefile before the calls to install_lib:

	# Copy the built libraries into a place where they will be found.
	cp --recursive $(CUPS_DIR)/cups/usr $(CUPS_DIR)
	cp --recursive $(CUPS_DIR)/filter/usr $(CUPS_DIR)

CUPS puts libcups.so.2 in $(CUPS_DIR)/cups/usr/lib/ after it has built it and it makes a symbolic link from libcups.so to it there. It puts libcupsimage.so.2 in $(CUPS_DIR)/filter/usr/lib/ after it has built it and it makes a symbolic link from libcupsimage.so to it there. The above copy commands make copies of these files in $(CUPS_DIR)/usr/lib.

The call to install libcups fails with the following:

Error: ptxd_lib_install: cannot find library 'libcups'!
make: *** [/home/z/z/phyCORE-AM335x-PD13.1.0/platform-phyCORE-AM335x/state/cups.targetinstall] Error 1
failed

I think I need to copy the libraries to somewhere else to get this to work, but I can't figure it out.

I saw something about the package's install stage having to be DESTDIR-aware. I'm not sure what that means, but I believe it might be related to this problem.

Thanks,

David Thomas

Hello, 

I have recently build a basic version of cups and cups-filters for that
same architecture, but I did not use ghostscript for this. If the target
printers are no postscript printers and you are not required to handle
genuine postscript files, you might be easier off without ghostscript.
If cups can not find the gstoraster program, it can try other routes to
produce the output. I have installed poppler for this.

My cups install target uses :

CUPS_INSTALL_OPT := \
	install DSTROOT=$(CUPS_PKGDIR)

Hello Bart,

Thanks for the information about poppler, a package that I was not aware of. I am not sure if it helps me because the system has to allow printing from Java to work and I believe Java's output is postscript.
