The main problem is how to config the AucTeX. There is no any other posts talking about the new AucTeX.
After 3 hours+ struggle, I decided to read the manual. Then every thing is clear. In the new version, it’s TeX-view-program-selection not TeX-output-view-style determine the viewer. But it’s still preserve these options. So if you want to use the “old” one, set “%vv” instead of “%V” for the View command in TeX-command-list.
For the new version,
1. Insert a new item of Tex-View-Program-List, with name sumatraPDF or any think you like. choose command and the command is : sumatrapdf %o.
2. save and restart EMACS,
3. change the viewer for predicate output-pdf to sumatraPDF in TeX-view-program-selection.
4. save and restart EMACS.
Now every ting works.
Problem, inverse search for new vesion of sumatraPDF. In fact I can not find the “File/Set” menu mentioned in this post.
Except this problem, I just follow him.
