I experience the same problem. Do you solved your issue? I am trying hard to solve but with no success thus far.
No, to be honest rtags completion has always been very hit or miss for me.
I'm seeing this same behavior. In fact, while finding symbols appears to work fine, diagnostics and completion just seem to hang at the prompt. For example:
14:42 Vulcan:ledger $ rc --list-symbols fn_amount_
fn_amount_expr
fn_amount_expr(ledger::call_scope_t &)
fn_amount_expr(ledger::call_scope_t &)::scope
This responds almost instantly. However:
rc --synchronous-completions --code-complete-at ~/Projects/ledger/src/report.cc:1365:38
This hangs indefinitely. As does rc -m --elisp
.
As a result, M-.
works just fine, but neither flycheck nor company work at all.
I can get completion to work when I install using (rtags-install)
but not when I use the AUR package. The rc
process hangs indefinitely in that case as previously mentioned.
latest 2.18
rtags - completion fails almost always. During that time emacs hangs up for a while.
In rc -v -g log I can see plenty of same messages about completion request without any responses.
Related to #1103, #989, and maybe #818 too
(adding here, as my other issue got closed as duplicate)
Just compiled a new rtags from Git and it still often fails to complete.
It seems to work pretty reliable when completing after a "." or "->" (although it seems to list private members now...). But other cases still only work sometimes. I just tried to complete a local variable after the first few chars, didn't work. Completing a vector "foo.pushb" (2nd _ is the cursor), "No completions found" ... Sometimes completion works if I indent 7, 10, 20 .. characters.
It does not hang for me though...
Hey guys, Swassie has created a PR yesterday, with fix for completion in RTags. Can you guys try https://github.com/Andersbakken/rtags/commit/b6f578173e53df2d4c4560ae82087e377a4aa080, and check if it works now. Thanks!
First impression: That did the trick! Cool. Should this be the first time having truly working smart completion and navigation in Emacs, after all those years fighting with Cedet and what not?! :)
Glad to hear that. Yeah, Cedet is a bit of a pain in the ass :-), though quit useful if you are new to Emacs, and are used to an IDE.
There are some other Clang/LLVM based parsers around, like irony, ycmd, cquery...

Problem description
Completion does not work
Expected behavior
I expected a list of completions.
Actual behavior
A request for completion almost always results in the following from elisp:
Company: An error occurred in auto-begin Company: backend company-rtags async timeout with args (candidates )
I have increased the timeout to 10 secs, which is much longer than what it takes for the translation unit to compile from scratch.
Environment
Ubuntu 17.04
LLVM/Clang version: clang version 4.0.0-1ubuntu1 (tags/RELEASE_400/rc1)
Feature request
Describe the feature we should add to RTags.
