Problem description

Preamble pch files (e.g. /tmp/preamble-beb28d.pch) soon exhaust a small /tmp file system directory.

Expected behavior

I would expect a configuration option to set the path name to pch files destination.

Environment

• Your operating system: Red Hat 6.7

• LLVM/Clang version: 3.9.1/3.9.1

Feature request

Add option to specify path to pch files. I do not really use clang, therefore, I do not know its options and features much. It could very well be that my request is something to be set on that side instead. But given that it is rdm which triggers those files then I'm trying here.

[Andersbakken]

These are produced by clang but I figured out that you can control where clang puts them by setting TMPDIR

E.g.

TMPDIR=/biggertmp rdm ...

that works; many thanks for your help, Anders.

I actually went back and fixed this properly now :-)

@Andersbakken How to disable preamble file

[Andersbakken]

I think it might not happen if you run like this:

--rp-daemon=0

Note that this likely will make indexing slower.
