Thanks Scott. It works with Maxima, not with Maple. When I run lyx from the
command line, the console shows the following:
use equation inset
use cell: [char 4 mathalpha][char * mathalpha][sup [char x mathalpha] [char
2 mathalpha]][char + mathalpha][char 8 mathalpha][char * mathalpha][char x
mathalpha][char * mathalpha][char y mathalpha][char + mathalpha][char 4
mathalpha][char * mathalpha][sup [char y mathalpha] [char 2 mathalpha]]
ar: '[char 4 mathalpha][char * mathalpha][sup [char x mathalpha] [char 2
mathalpha]][char + mathalpha][char 8 mathalpha][char * mathalpha][char x
mathalpha][char * mathalpha][char y mathalpha][char + mathalpha][char 4
mathalpha][char * mathalpha][sup [char y mathalpha] [char 2 mathalpha]]'
ms: '4*x^(2) + 8*x*y+4*y^(2)'
checking expr: '4*x^(2) + 8*x*y+4*y^(2)'
calling: mint -i 1 -S -s -q -q
input: '4*x^(2) + 8*x*y+4*y^(2);'
sh: 1: mint: not found
calling: maple -q
input: 'readlib(latex):
`latex/csname_font` := ``:
`latex/latex/matrix` := subs(`[`=`(`, `]`=`)`,eval(`latex/latex/matrix`)):
`latex/latex/*` := subs(`\,`=`\cdot `,eval(`latex/latex/*`)):
`latex/latex/matrix`:= subs(`\\\\\\noalign{\\medskip}` =
`\\\\`,eval(`latex/latex/matrix`)):
latex(factor(4*x^(2) + 8*x*y+4*y^(2)));quit;'
sh: 1: maple: not found
So, two things: something called "mint" is not found, nor is maple.
Nevertheless, if I run Maple from the command line it runs perfectly. Are
there two PATH variables, one for the terminal and one for the Ubuntu
graphic environment? May be this is the problem.
Thanks for your help. Regards.
