- can't load font '-*-helvetica-medium-r-normal-*-12-*-*-*-*-*-iso8859-1'

Dear fellow fedora users,

I have compiled and installed x48(an hp48 g/gx calculator emulator) on Fedora.  When I try to run it I get error:

[olivares@localhost ~]$ x48
x48: using XShm extension.
x48: /home/olivares/.hp48/hp48 is a version 0.4.0 file, converting
x48: FATAL ERROR, exit.
  - can't load font '-*-helvetica-medium-r-normal-*-12-*-*-*-*-*-iso8859-1'
  - Please change resource 'connectionFont'
[olivares@localhost ~]$

How can I overcome this error and run x48 on fedora?

Thanks & Best Regards,

Antonio

Do you have the package xorg-x11-fonts-ISO8859-1-100dpi installed on
your system?

Then you'll have to change connectionFont to some font that you do
have.  What you have now is something like this (using a wildcard,
because I don't know what should go there):

*connectionFont: -*-helvetica-medium-r-normal-*-12-*-*-*-*-*-iso8859-1

You'll need to determine which font you want to use.  The
xorg-x11-apps package contains xfontsel, which can help you determine
a font string to use.  You might want to start by replacing the
"iso8859-1" part with wildcards, i.e.,

*connectionFont: -*-helvetica-medium-r-normal-*-12-*-*-*-*-*-*-*

Once you've got the font string you want, add it to your ~/.Xresources
or ~/.Xdefaults file.  Wow, I haven't had to do any of this for years.
My memory is a little hazy, but I think that's approximately what
needs to be done. :-)

I agree, this dredged up some bad memories of X fonts and font
servers.

on my f32 system with the X font packages installed, I don't see a
size 12 font:

$ xlsfonts |grep helvetica-medium-r-normal
-adobe-helvetica-medium-r-normal--11-80-100-100-p-56-iso8859-1
-adobe-helvetica-medium-r-normal--14-100-100-100-p-76-iso8859-1
-adobe-helvetica-medium-r-normal--17-120-100-100-p-88-iso8859-1
-adobe-helvetica-medium-r-normal--20-140-100-100-p-100-iso8859-1
-adobe-helvetica-medium-r-normal--25-180-100-100-p-130-iso8859-1
-adobe-helvetica-medium-r-normal--34-240-100-100-p-176-iso8859-1

So, I suspect the config for the HP48 emulator (another old memory,
RPN rocks!) has a size 12 font set someplace.

Thank you very much Sir!  Your message has helped me resolve this issue.  I changed the 12 to 11 and voila it worked!

[olivares@localhost Documents]$ xlsfonts |grep helvetica-medium-r-normal

My sister bought me an HP48G with RPN in 1993 and I have it at home, but I like to have it run virtually and now thanks to your suggestion, I got it working :)

Best Regards,

Antonio
