texexec slow

texexec slow

[R. Bastian]

Hi,

I am new on this list. I use pftex and would use ConTeXt installed with texlive/2007.

'ruby' and 'pdftex' work fine, but 'texexec' (texexec.rb "$@") is very slow.

Where con I get the doc or what shall I do ?

Thanks,

I tested 'texexec' on another computer (Kubuntu 7.10, TL2007, ruby 1.8.6) and it works,
but I need it on [Debian 5.0, Gnome, ruby 1.8.7] where it fails.

I dont know; 'first-setup.sh' erased the path to the format files ;-)
but 'pdflatex' was very clever. (I must reinstall 'texlive'.)

I do not know if this is related or not...but

Occasionally I also find that texexec is extremely slow. (Takes about a 
minute to initiate and then runs fine). This happens, when my internet 
connection is in a bad state (which means that ping to a server also time 
out). In that situation texmfstart takes ages to get a response from drb. 
Whenever I kill the process by ^C, the interupt is in  the call to drb. I 
do not remember the exact interupt message, but I will try to get more 
information when this happens the next time. If I avoid texmfstart, ie, 
run ruby $TEXMFCONTEXT/scripts/context/ruby/texexec.rb directly, it runs 
fine.

"ruby $TEXMFCONTEXT/scripts/context/ruby/texexec.rb <texfile>"

Haha ! with this tip I get an error message from 'pdftex' :
libstdc++.so.5 ... No such file ...

The libstdc++6 is installed. What can I do ?

i dont know if it is of interest for you:
- I switched back to TL2007 (now pdftex finds 'cont-en')
- texexec source.tex compiles 3 min 14 sec for 1 page of pdf
- pdftex -fmt cont-en compiles  1 sec and produces a dvi file

Thanks for your help.

Taco, what's the state with this particular library dependency?

There are two problems:
- texexec might not always check if pdftex fails and it eats some
messages inbetween
- library dependency should be fixed

What about
    texexec --make --all
?

When I started using ConTeXt (2004) the average running time for
"hello world" documents was definitely somewhere between 30 seconds
and a minute. But it has improved dramaticaly over time (3 seconds in
the second run as I mentioned) whereas LaTeX runtime has increased.

But TeXLive 2007 is not so old after all, so it's still a bit strange.

Weird. Maybe texexec does some crazy stuff, but it's a bit hard to
tell what exactly.

Not 100% sure but I think it should be better now (or at least
soon), as Thanh wrote he has updated the build script for pdftex.

One thing to remember is that to make pdftex use a static
libstdc++, the machine you are compiling pdftex on has to have
the static version of libstdc++ installed.

Best wishes,
Taco

I have checked. There are both libstdc++5 and libstdc++5-3.3-dev
pacakges installed on Debian and locate showed both ".so" and ".a"
file, but I figured out that it also has libstdc++6 (which was not
installed).

How does pdftex building process decide which one to use in case that
both are installed?

hm, there is some code in there for a distributed kpse server but as it 
is not enabled by default i wonder ... anyhow, i'll remove that code

also, one can use mtxrun as dropin (but the specific aspect has a 
buglet) so in upcoming distributions we will use that
