[ptxdist] Cross-compiling gstoraster

[ptxdist] Cross-compiling gstoraster

[David Thomas]

Hello,

I have got further now. I saw that the path was wrong for installation of libraries. I have fixed that so please disregard my previous question.

My libcups.so library is now installed to the following directories:

platform-phyCORE-AM335x/root/usr/lib
platform-phyCORE-AM335x/root-debug/usr/lib
platform-phyCORE-AM335x/sysroot-target/usr/lib

My raster.h header file is installed to these:

platform-phyCORE-AM335x/root/usr/include/cups
platform-phyCORE-AM335x/root-debug/usr/include/cups
platform-phyCORE-AM335x/sysroot-target/usr/include/cups

Ghostscript's configure still fails to pick it up:

checking cups/raster.h usability... no
checking cups/raster.h presence... no
checking for cups/raster.h... no

It must therefore be looking somewhere else for the files.

Questions are:

1. Where is it looking? (I suppose this is the --sysroot used by gcc and the binutils.)
2. What would a typical macro look like to install a library there?

Thanks.

Normally you should not have any non runtime files like header files on
you target root. This is only needed at compile time.

Difficult to say if we don't know what you doing in the rule files,
please send it as RFC to this list and I can check it. Please use
"git send-email" for that and we need all rule files including
dependencies, maybe we can get these rules mainline then.

I see in ghostscript configure some options like:

--enable-cups
--with-pdftoraster

do you acitvated that in the rule file of ghostscript?

Hi Alex,

Thanks for the info about sysroot-target.

I have added --enable-cups and --with-install-cups to the configure options. I will check whether more are needed but configure needs to find raster.h to allow ghostscript to build gstoraster.

I am running a Linux virtualbox on Windows and I don't know how to set up the mailing parameters for git send-email so I have instead used git format-patch and I will copy the patches into the two next emails.

Thanks,

David

Hi David,

I looked last night a little bit deeper into cups and ghostscript
buildsystems and it seems that cross-compiling these tools is a mess.

I will see what I can do for it. Don't believe that I can do miracles.
Of course there must a way to cross compiling it. :-)

Hi Alex,

Thank you so much for looking into this, whether or not you get anywhere with it.

I'm looking at stepping outside the Ghostscript make system and producing a custom command to run in the ptxdist build rules to make my version, perhaps after the standard make system has built everything else (which now works, at least as far as compiling goes). I don't consider it the correct approach but I can't see how else to proceed at this time.

Thanks,
David

Hello,

I would like to express my thanks to all of you, and especially Juergen. With minor modifications, his patches for Ghostscript worked fine on my end, and I now have CUPS and Ghostscript working fine on my target!

I have provided Juergen with a copy of my rules and patches. It would be really nice to see CUPS and GS make it into the main PTXdist and I hope what I have done helps.

Many thanks,
David
