Hello,
I use the context minimal with updating to lastest beta. when using $\doteq$ in my equation, texexec catch an error:
! Illegal unit of measure (pt inserted).
<to be read again>
=
\buildrel ...mathrel {\mathop {\kern \zerocount #2
}\limits ^{#1}}
l.3 Test $\doteq
$
?
I check the definition in math-pln.mkii, the \doteq is defined as:
\def\buildrel#1\over#2%
{\mathrel{\mathop{\kern\zerocount#2}\limits^{#1}}}
\def\doteq
{\buildrel\textstyle.\over=}
The problem seems caused by \zerocount. After comparing with the definition in math-pln.mkiv, I changed it to \zeropoint and texexec run successfully.
Regards,
Andy
