Hello ! Sorry, I'm a bit new to context ... but I try it for presentation slides... And up to now, I like it very much ... I tried to compile different examples included in the base distribution ... but some, I fail to compile ... And I do not know where I'm wrong ... For example, I tried s-pre-61.tex to compile and it fails ... here is the output of the compile process ... # cp /usr/share/texmf/tex/context/base/s-pre-61.tex . oli@olinux:~/E/Context # texexec --pdf --mode=demo s-pre-61.tex TeXExec 3.1 - ConTeXt / PRAGMA ADE 1997-2002 executable : pdfetex format : cont-en inputfile : s-pre-61 output : pdftex interface : en current mode : demo TeX run : 1 This is pdfeTeX, Version 3.14159-1.10b-2.1 (Web2C 7.4.5) entering extended mode (./s-pre-61.tex{/usr/share/texmf/pdftex/config/pdftex.cfg} ConTeXt ver: 2003.1.31 fmt: 2005.1.21 int: english mes: english language : language en is active system : cont-new loaded (/usr/share/texmf/tex/context/base/cont-new.tex systems : beware: some patches loaded from cont-new.tex! system (E-TEX) : [line 726] \ifcsname ) system : cont-old loaded (/usr/share/texmf/tex/context/base/cont-old.tex loading : Context Old Macros ) system : cont-fil loaded (/usr/share/texmf/tex/context/base/cont-fil.tex loading : Context File Synonyms ) bodyfont : 12pt rm is loaded language : patterns 2:2-en-2 3:2-uk-2 4:2-de-2 5:2-fr-2 6:2-es-2 7:2-it-2 8:2-nl-2 loaded specials : tex,postscript,rokicki loaded system : s-pre-61.top loaded (./s-pre-61.top specials : loading definition file tpd (/usr/share/texmf/tex/context/base/spec-tpd.tex specials : loading definition file fdf (/usr/share/texmf/tex/context/base/spec-fdf.tex system (E-TEX) : [line 1815] \ifcsname ) specials : fdf loaded ) specials : fdf,tpd loaded ) pdftex : needs map file: original-context-symbol.map pdftex : needs map file: pl0-ams-cmr.map pdftex : needs map file: original-vogel-symbol.map system : macros of module pre-60 loaded (/usr/share/texmf/tex/context/base/s-pre-60.tex javascript : loading script set stp (/usr/share/texmf/tex/context/base/java-stp.tex) !
