This is long, so here's my summary: BLODA did indeed cause the permission denied errors while running autogen.sh. However, broken inverse search appears unrelated. As for broken inverse search, all evidence points to a regression between 1.6.1 and branch.
Now for the details. As promised, here are the answers to your questions: > 2) Are you running more instances of the same lyx version? Task Manager shows a single instance of lyx.exe. > 3) Are you sure that source specials are activated? Yes. Otherwise, my DVI/PDF viewer would not be giving me valid line numbers. > 4) Version 1.6.1 (where inverse DVI search works) has been compiled by > you or are you using a package? Version 1.6.1 works both when I use the package, and when I compile it myself. > 1) Are you using the lyxpipe or the lyxsocket for communicating with lyx? Neither. For the purposes of debugging, I don't want to worry about interprocess communication issues. My script simply echos %f %l, which I enter into the command buffer: server-goto-file-row /tmp/lyx_tmpdir.JL4960/lyx_tmpbuf1/LaTeXConfig.tex 191 [LyX usually jumps to the first line, unless I'm using 1.6.1] I did verify that both lyxsocket and lyxpipe give the same result. $ lyxclient -g /tmp/lyx_tmpdir.JL4960/lyx_tmpbuf1/LaTeXConfig.tex 191 lyxclient: Connected to /tmp/lyx_tmpdir.JL4960/lyxsocket INFO:server-goto-file-row /tmp/lyx_tmpdir.JL4960/lyx_tmpbuf1/LaTeXConfig.tex 191: $ echo "LYXCMD:revdvi:server-goto-file-row:/tmp/lyx_tmpdir.JL4644/lyx_tmpbuf0/LaTeXConfig.tex 191" > .lyx161src/mypipe.in $ cat .lyx161src/mypipe.out INFO:revdvi:server-goto-file-row: To reiterate, any of these methods work in 1.6.1, while none work in branch. After glancing over the code, I hypothesize that the issue might result from "RowList rowlist" having size zero for some unknown reason. *Permissions errors when running autogen.sh* As far as I can tell, those errors did result from BLODA, specifically McAfee. When On-Access Scanner is enabled, I can sometimes reproduce the error. After numerous tests of repeatedly switching it off and on, I was unable to reproduce the error with O.A.S. disabled. Server-goto-file-row still fails with O.A.S. disabled. -Ben
