#182 Urgent: recent latex updates (already in TeXLive) break TeXMaths

[Sergio Callegari]

With the most recent latex from TeXLive, using the xetex or luatex engines with TeXMaths is impossible.

The presence of the dvips option in the \documentclass[10pt,dvips]{article} causes LaTeX to error out with Backend request inconsistent with engine: using 'xetex' (LaTeX)backend. (or the same with luatex).

Removing dvips fixes the problem. It is unclear to me at this point if this is a bug in LaTeX.

[Sergio Callegari]

My mistake, with luatex, it is fine. Breakage is with xetex only. TexMathsEquations.xba needs to be changed so that dvips that is not passed with luatex is not passed with xetex either

[Sergio Callegari]

... Sorry to get again on this. More tests... the dvips option is not the cause of the breakage.

It is something that should be fixed, not urgent. Something has changed in the way in which the various pieces of the system seek fonts and is breaking because of capitalization. Not TeXMaths fault, I think.

Having a "debug" option leaving all the temp files in place would help.

Sorry for the noise.

No problem. I'll test too. What is the problematic TexLive version (and system)?
