I'm trying to set up my preferred mix of fonts from mathptmx and newtxmath. This would require using the largsymbols font from newtxmath, since I like its integrals better than those from mathptmx. However, this one font just won't load. Here is a simple snippet illustrating the problem:
\documentclass[a4paper]{report}
\DeclareSymbolFont{largesymbols}{OMX}{ntxex}{m}{n}
\begin{document}
$\forall\exists<>\leq\geq\int\subseteq\supseteq$
\[\int abcdefghijklmnopqrstuvwxyz+-=\alpha\]
\end{document}
Result with pdfTeX:

Same goes for XeLaTeX. Now, in a more complicated situation with a package of mine, I got an error. In this case, I get a warning, and the wrong shape for the integral: I get the Computer Modern one, the default one, if I read that cmex correctly. Indeed, adding
\SetSymbolFont{largesymbols}{bold}{OMX}{ntxex}{b}{n}
\DeclareFontSubstitution{OMX}{ntxex}{m}{n}
produces, with XeLaTeX:

Yet the code is copied literally from the package, so what is going on here? Why is that .fd not found? I know where it is, but TeX seems not to, and if I put it where TeX can find it, it starts doing strange things and calling metafont and ending up with no .tfm:

Why is this coming about? How do I get the desired shape for the integral symbol without loading newtxmath directly?
Best Answer
Provided you don't need scaling, at a minimum you need something like this:
However, if you only want to use a couple of symbols from the font, this is not a good way to do it (because everything which uses
largesymbolswill now use thenewtxmathfonts) and it won't work properly anyway (becauseLMXis not equivalent toOMX).So it is better to create a new symbol font and use that just to redefine the symbols you want (as egreg's answer does).
You might, however, also want to use the integral symbols for maths extension A from
newtxmath. In that case, you need to set up an additional font, but this configuration can be taken straight fromnewtxmath.stysince it already defines an additional symbol font.Putting this together:
