I am trying to use the simplefonts approach to get Euler for math, along with TeX Gyre fonts for text.

Here is setup magic from Hans and Aditya from August 2013:

\usetypescriptfile[euler] \starttypescript[myfamily] \definetypeface[myfamily][rm][serif][pagella][default] \definetypeface[myfamily][ss][sans] [dejavu][default] \definetypeface[myfamily][tt][mono] [inconsolata][default] \definetypeface[myfamily][mm][math] [pagellaovereuler][default] \stoptypescript

\usetypescript[myfamily] \setupbodyfont[myfamily] \appendtoks \rm \to \everymathematics \setupmathematics [lcgreek=normal, ucgreek=normal]

One can change the families, e.g. schola for pagella, etc., but I think the last [pagellaovereuler] and the rest has to stay.

Sadly, I get this:

INPUT FILE ========== \starttypescript[myfamily] \definetypeface[myfamily][rm][serif][pagella][default] \definetypeface[myfamily][ss][sans] [dejavu][default] \definetypeface[myfamily][tt][mono] [inconsolata][default] \definetypeface[myfamily][mm][math] [pagellaovereuler][default] \stoptypescript

\usetypescript[myfamily] \setupbodyfont[myfamily] \appendtoks \rm \to \everymathematics \setupmathematics [lcgreek=normal, ucgreek=normal]

\starttext \startformula x = y + z \stopformula \stoptext

What am I missing here?

You don’t have the opentype version [1] of the euler math font on your system which is needed when you either the \definefontfamily command or the pagellaovereuler typescript. When you install the font on your system you can use it as shown in the following example. \definefontfamily [myfamily] [serif] [Linux Libertine O] \definefontfamily [myfamily] [math] [Neo Euler] \setupbodyfont [myfamily] \starttext \m{c^2 = a^2 + b^2} \stoptext [1] https://github.com/khaledhosny/euler-otf https://github.com/khaledhosny/euler-otf Wolfgang

Indeed, getting the OTF fixed all the issues. Thanks Wolfgang and John! Kumar -- Kumar Appaiah
