Hi,
I am continuing my BLFS build by attempting to add printing support.
I have just managed to build CUPS-1.5.0, jasper-1.900.1,
Ghostscript-9.04, Gutenprint-5.2.7 (with kernel linux-3.0.4) with only
minor problems.
CUPS-1.5.0 and jasper-1.900.1 built OK.
To get Ghostscript-9.04 to build, I had to split the sed after configure
into two separate commands to get it to work.
Gutenprint-5.2.7 needed a sed to add stdio.h to
src/CUPS/commandtoepson.c and commandtocanon.c.
When I logged on to localhost:631, it did not exist! However, the other
parts of localhost:631 (/printers etc.) all worked OK.
So I was able to get CUPS to recognise and setup my EPSON SX415 printer.
I was able to print successfully a jpeg file, which proved the interface
to the printer.
Unfortunately, I could not print any other type of file!
I get the "Unsupported document-format" error each time.
I think I am missing a pstoraster (or gstoraster) file which should be
part of Ghostscript.
My install logs (on an older system) show /etc/cups.gstoraster.convs
and /usr/lib/cupsfilter/gstoraster - the latter is the program
created as bin/gstoraster during the install or soinstall (not sure
which).
I'm unsure what you mean by 'it did not exist!' - clearly some of
cups is present, or else you would not have been able to get cups to
find your printer.
Trying to debug errors in the printing stack is hard, if altering
the cups logging to 'verbose' doesn't help. I suspect you might
have already done that.
My own build of ghostscript-9.04 is quite different from what's
in the book: apart from some fixes from, I think, ubuntu and fedora,
I build with
rm -rf libpng jpeg lcms expat freetype zlib tiff jasper jbig2dec
./configure --prefix=/usr --with-system-libtiff --enable-dynamic \
--with-drivers=ALL,x11 --disable-compile-inits \
--without-jasper \
--without-jbig2dec \
--enable-cups --with-install-cups
I decided I didn't need jasper or jbig2dec in my own builds.
It still needs a sed for system expat -
sed -i -e 's|=imdi|&\n\n# Use system expat library\n\nSHARE_EXPAT=1|'
Makefile
but seems to correctly determine the others, including my installed
lcms1.
then I build with
make&& make so
make install soinstall
and I still do the old 'extra headers and symlinks' although I
doubt anything on my system needs them:
install -v -m644 base/*.h /usr/include/ghostscript
ln -v -s -f ghostscript /usr/include/ps
ĸen
Thanks for the quick reply, Ken.
I have just built Ghostscript-9.04 using your suggested settings and I
now have a /usr/lib/cups/filter/gstoraster.
Unfortunately, when I try to print a Postscript file, gstoraster returns
a Status 11
and "dmesg" shows that gs has crashed.
dmesg output:
gs[2000]: segfault at c47bd5c ip 083c6488 sp bff38da0 error 4 in
gs[8048000+4a9000]
I have further investigating to do.
A better explanation of 'localhost:631 did not exist' is:
When I enter localhost:631 into Firefox, I get a "Not Found" error.
If I enter localhost:631/Printers, I get the expected CUPS page.
I can access all the other CUPS pages OK, but not the Home page.
This is a minor problem in itself.
I only mentioned it in case it is a symptom of a more serious fault.
Thanks again,
pete
