So I don't need Tsuqouqoqy?

@bstaletic

I have no idea what that thing is. A jump to the type definition is provided by GoToType.

@Layamon

How can I fix this problem? It seems like ycm can not find stdc++ headers?

L-YM

@Layamon

already add these dir into ycm extra file... but not fix it

@RafaelRiosAsh

I tried installing ycm on my mac running 10.14.6, it obviously failed and I realized maybe too late that it's because of my gcc compiler, I read in one of the open issues that I could run an older version, I just have no idea how to do that, and haven't been able to find the answer anywhere, I was wondering if I could get some pointers

Boris Staletic

@bstaletic

@RafaelRiosAsh Checking out an older version is just git reset --hard 4e480a317d4858db91631c14883c5927243d4893 && git submodule update --init --recursive

Brian Orwe

@Borwe

Does anybody know how to make cmd completion pop up dialog on vim like it does on neovim ?

Boris Staletic

@bstaletic

:h wildmenu and <C-d> is closest thing vim offers.

Brian Orwe

@Borwe

Cool, thanks.

Brian Orwe

@Borwe

I am having problem with ycm and ultisnips, the hints for snippet completion popup, but pressing <CR> nor <Tab> makes it fill in the buffer.

Ben Jackson

@puremourning

what have you set as the ultisnips expand key?

Brian Orwe

@Borwe

no, is that a new thing? I think I used to be able to just use it out of box.

Ben Jackson

@puremourning

this is what i use

https://github.com/puremourning/.vim-mac/blob/master/vundle_plugins#L190-L193

it's been that way since forever

afaik, nothing has changed, but if you can git bisect and find a change in YCM which changed the behaviour for you let us know

Brian Orwe

@Borwe

My memory must be faultly then lol, let me check it out.

Works now, thanks.

@klement

Interesting thing happened for me just now. I installed YCM and did the install.py --clangd-completer stuff and server was shutting down. Complaining about missing ycm_core. Issue solved by doing apt install libtinfo5. I think this should be mentioned somewhere - or maybe even automagically checked. Ubuntu 20.04

Boris Staletic

@bstaletic

@klement What's the output of ldd ycm_core.so? That error shouldn't be a problem since a few years ago.

Ben Jackson

@puremourning

that looks to be tring to load libclang, which means --clang-completer

klement

@klement

Yes I was scared by the message so I provided both options - clang & clangd

without clang it complained I won't have any semantic completion for c/c++/etc

klement

@klement

but it seems that message is just plain wrong as it's working just fine with clangd-completer only ...

Ben Jackson

@puremourning

‘Complained’ ?

klement

@klement

ah yes a better word would be warned

ksekera@c984e4769eef ~/.v/b/YouCompleteMe (master)> ./install.py ---clangd-completer
...
-- Found PythonLibs: /usr/lib/python3.8/config-3.8-aarch64-linux-gnu/libpython3.8.so (found suitable version "3.8.5", minimum required is "3.6")
-- NOT using libclang, no semantic completion for C/C++/ObjC will be available
-- NOT using clang-tidy for static analysis.
...

so this warning is obviously not true in this case ...

Ben Jackson

@puremourning

It’s kinda true. But sure you can ignore it if using clangd

Boris Staletic

@bstaletic

@klement I don't know which liclang are you loading, but the one that we bundle does not depend on libtinfo.so.5.

The libclang from releases.llvm.org does depend on libtinfo.

klement

@klement

Well it did some downloads, but I also have clang-11 installed system-wide. Maybe it's preferred? Eitherway ... my issue is no longer an issue, just wanted to mention it in case anybody finds the info useful

Boris Staletic

@bstaletic

YCM will copy the chosen libclang to ycmd/third_party/clang/lib/libclang.so.$VERSION, so run ldd on that.

Alvin Sun

@alvinsunyixiao

I am cross compiling with ARM toolchains. My project generates a compile_commands.json, but YCM seems to append more system flags.

The compile commands does not include -resource-dir=xxx and everything after it. Is there a way to remove those flags?

I tried printing the flags in my .ycm_extra_conf.py, it seems like the flags returned by Settings function does not include those system flags.

Boris Staletic

@bstaletic

@alvinsunyixiao Switch to clangd and skip the extra conf.

Johannes Wikner

@sktt

hey, how can tell YCM the path of my header files?

Boris Staletic

@bstaletic

Do you have a compile_commands.json

RoachZhao

@roachsinai

Hi, there. Does YcmCompleter GoToDefinition support open the file in current window?
