kandi X-RAY | ccls Summary

ccls is a C++ library typically used in Editor applications. ccls has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

ccls, which originates from cquery, is a C/C++/Objective-C language server. It has a global view of the code base and support a lot of cross reference features, see wiki/FAQ. It starts indexing the whole project (including subprojects if exist) parallelly when you open the first file, while the main thread can serve requests before the indexing is complete. Saving files will incrementally update the index.

How to build CCLS on Linux (performed on Fedora)?

Asked 2022-Apr-09 at 18:35

I have tried using CMake to build ccls many times and I have just about given so if anyone has a way to do it that would be mega helpful.

I am on Fedora Linux and I am using the repo to get ccls as the prebuilt binaries don't work.

Any help would be appreciated. Thanks.

To get it to work on Fedora (I don't see any reason why it shouldn't work on other Linux distros) this is how I did it step by step:

Quick note: You may want to use sudo yum install clang-devel and sudo yum install llvm-devel since they potentially hold needed dependencies. Also make sure you have downloaded the other things you will need as instructed on the ccls wiki.

Firstly I used git clone --depth=1 --recursive https://github.com/MaskRay/ccls to clone the repo into a folder.
Secondly I went into the ccls folder and used cmake .. Which built the required things.
Thirdly I the used the make command to fully build the repo and generate the ccls executable.
Then I created a bin directory in the home directory and moved the ccls executable into it.
Then I went into the .bashrc to add ccls to the system path and added the line export PATH="/home/$USER/bin:$PATH" to the final line of the bashrc. Then exited the file and used source ~/.bashrc to force a reset
Finally I added the ccls language server settings to the coc config:

CMake project builds but shows include error in LSP

Asked 2022-Feb-26 at 13:31

I'm working on a C++ project using ccls (the LSP language server) and lsp-mode in Emacs. I also have a CMake project definition for my project. My project builds correctly with make using the Makefile generated by CMake, but ccls says that my #include is not found.

Here's the project structure:

ccls tries to find SomeClass.hpp in the root of your project. It should be fine when you change the first line of your main.cpp to this (At least for me it resolved the error):

In short, you want to remove the section beginning and end lines as well as the comment characters at the beginning of a line, and print the lines in the section. Since you use GNU bash, here's a suggestion with GNU sed:

How do I add a compiled application to the gitignore file?

ANSWER

Answered 2021-Sep-12 at 21:58

The pattern /Godot.app should match your file just fine. However, if the file is already added to the repository, then .gitignore has no effect on it. The .gitignore file affects only files which are untracked.

In your case, your file is in the history, and it needs to be removed from the entire history if you want to upload it to GitHub. You can do a git rebase -i to go back in history to the point at which it was added and remove it from history, or, if it was added in the most recent commit, you can remove it with git rm -r Godot.app and then run git commit --amend.

You could also use git filter-branch or git filter-repo to filter it out from the history.

The dstuff alias ends with ;, so when dsc is expanded you get echo;; dkm at the end. Shell syntax doesn't allow two ; in a row.

Get rid of the ; at the end of the dstuff alias.

QUESTION

Installing ccls through Homebrew outputs caveats messages related to libffi and llvm

Asked 2021-Jan-06 at 14:52

I'm trying to set my neovim C++ development environment, and want to use ccls as my coc language server.

When I installed ccls using Homebrew, it installs libffi and llvm as dependencies. It seems like ccls is installed successfully, but it seems like I need to configure PATH variable,LDFLAGS and CPPFLAGS.

But I don't know what libffi and llvm are for, and they suggest different LDFLAGS and CPPFLAGS, which is confusing.

Is it okay not to export any variables to use ccls? Or, which version should I export in my ~/.zshrc?

Below is my console output for brew install ccls.

...

ANSWER

Answered 2021-Jan-06 at 14:52

libffi is only a library. And llvm is a compiler infrastructure. And libc++ is the C++ standard library of the LLVM Project. You can use the LLVM library or the GNU (libstdc++) one. It depends on your software project (or your personal preferences) what library you use.

Since macOS does already deliver a llvm installation you can optionally switch to the one installed as dependency by brew – which is not required.

The LDFLAGS environment variable does hold additional flags which is passed by your compiler (gcc/g++ or clang/clang++) to the linker, i.e. adding the path where the linker can find the library object files which are then, if required/used, linked against your binary.

And CPPFLAGS does the same, but this time the flags are targeting the compiler directly, i.e. adding an additional search path for the header files of the library.

And in your case you don't have to export any (additional) variables from your .zshrc, ccls will work fine for you without defining those variables.
