I think I've got to bottom of esint problem on Centos/RedHat. There simply is no esint.sty available.

Error: Nothing to do The RedHat/Centos packagers did not include esint, on the grounds that the particular integrals provided there are probably available elsewhere. On Fedora, however, the full TexLive collection includes about 3 times as much stuff, and one of the packages is the one we need, # rpm -qa | grep esint texlive-esint-type1-svn15878.0-1.1EL7.noarch texlive-esint-svn15878.1.1-1.1EL7.noarch I got the source packaging from Fedora and built the whole TexLive snapshot on EL7. I couldn't believe my eyes. They've split TexLive into 5500 packages. You can see, I put them in the repo I maintain. http://pj.freefaculty.org/EL I did install the esint and apa6 packages, but in this test system, I left the TeXLive that was delivered with Centos in place. LyX 2.1.2 works well in this Centos system. I believe this may not be entirely necessary, however. The esint package is not truly required to compile an elementary document. However, inside LyX, there is a switch under document / settings that says use esint automatically. I think that doesn't work properly, it tries to use esint even on an ordinary integral. If we change esint to "do not load" then the basic document compiles. I see a few other wrinkles in Centos with documents that have bibliographies (references filled with (?) but LyX does not throw an error). If I figure those things out, I'll let you know.
