I just got the "glossaries" package working by using the supplied information in the "LaTeX Community Know How Section", specifically: Using makeindex explicitly. To build my PDF file from Texworks i now run five steps:
Can I somehow combine all these steps so only one click on the green "Typeset" button is necessary to produce the final PDF?
I used to use TeXworks default run option "PDFLaTeX+MakeIndex+BibTeX" which uses texify.exe before. Can I combine the steps above with this option? I assume that I'm missing the BibTeX command now, don't I? Are the new options for MiKTeX and PDFLaTeX identical to the former ones?
You could try using latexmk. There's a section in latexmk's documentation on how to add the dependences required for makeglossaries. Then you just need to add latexmk as a new tool in TeXworks (See, for example, this page which includes how to add latexmk as a new tool in TeXworks).
