I have found a couple of scenarios that can cause that error.  The first
is the lack of libstdc++ compiled into ghostscript and the second is
omni changed function naming (removing C++ name mangling).

I am currently working on some backwards compatibility for that scenario.
Omni's CVS has that checked in.

Actually, espgs and omni are two separate projects.  In the latest version
of espgs, it only checks for glib support for that message.  Earlier
versions checked for a link to omni source as well.

So, one would first build espgs and then build omni.

No.  I would recommend that you check out the latest CVS of both projects.

Only the current epsgs CVS will work for both 7.3 and 8.0 RedHat systems.

Hope that helps.

Thanks Mark.

The above helps some, but I am not exactly sure how to proceed yet.

1)Does the build of the Omni Project build the libomni.so library(a 
shared library I presume)? The library is not currently resident on my 
system, so I got to build it somehow. The library missing could be my 
problem. I created dummy libomni.so's in /lib and /usr/lib to see if I 
would get a different error, but I get the same error, indicating(maybe) 
that I need the fixes which are in CVS and the tarball on the omni 
download site?
2)The Omni function compiled into espgs is just an interface to the 
libomni.so library?
3)Our system, in general does not use the CVS's for standard 
installation, but rather source(not binary or rpm's)tarballs. I don't 
know how to use a CVS in any case(guess I could learn tho).
4)You say the latest CVS for both projects has the latest fix you 
alluded to, so I presume the fixes will show up in espgs 7.05.6 or later?

Can you help any here Jason(Jason is our printer guru in SourceMage)?

Thanks,

Hi, John.

I have been ill the last week, and work has piled up.  I will look into 
getting around this problem, but it may be a couple of days before I can get 
to it.

Hi Jason,
Yes I remember you saying something about not feeling well in a previous 
post.  No worries.  I have been fooling with this thing off and on for 
about a week with no success.  The espgs downloads the Omni tarball as 
you well know, but does not install it.  I tried to install Omni 
manually but got some obscure configure?  errors.  I will keep hacking 
on it and let you know how it is going.

If those fixes Mark Hamzy alluded to are only in the CVS, and if they 
affect espgs 7.0.5 are we screwed until another release?

Meanwhile, GET WELL.
JohnC

Mark, Jason,
As I indicated before I got configure errors trying to compile 
Omni-0.7.1.  I noticed today that there was a new version Omni-0.7.2 
available.  I downloaded this manually and did a
compile/make install/make installLocal, no problems.  The libomni.so 
file was installed into /opt/Omni/lib.

When trying to print I still get the error.  I may not have my 
cupsomatic and PATH's set up right.  I added /opt/Omni/bin to my PATH. 
 In the /usr/lib/cups/filter/cupsomatic file, I did:
my $execpath = "/usr/bin:/bin:/opt/Omni/bin";

Mark, how does the Omni interface know where to look for libomni.so. 
 All the libomni's are installed in /opt/Omni/lib so I tried copying 
them to /lib but still get the error.

Jason, I guess from what Mark told us, the espgs we are installing may 
have the error in it.

Mark, you believe this is a correct assessment based on the above?  Or 
am I missing something.

Jason, Mark,
A follow up and final on this.  I finally got my printer to work 
properly.  I did the following to get there.
1) Downloaded omni-0.7.2.  Configured, compiled, installed AOK. 
 libomni.so showed up in /opt/omni/lib.  Mark, I had a small proplem 
here.  I deleted all the printers in devices.mak except Panasonic, and 
the compile failed with some error related to Hewlett Packard.  I add HP 
back to devices.mak and compile went OK.
2) Downloaded espgs-7.05.5 from the CVS, did a makesrcdist, replaced my 
version in /var/spool/sorcery.  An install(cast -r -c) of espgs then 
configured, compiled, and installed OK.
3) Reviewed all my cupsomatic and PPD stuff
4) Printed a simple text file OK
5) Tried the test print in CUPS, and it failed looking for a particular 
font.
6) Investigation showed the standard ghostscript fonts had disappeard. 
 Probably because espgs install had done away with them.
7) Installed(cast -r -c) ghostscript-fonts-std, and the CUPS test , 
print a test page, worked.

Jason, it appears the espgs spell needs to be upgraded for the omniprint 
driver.  You copy?
