Hi, I have some problems setting up a C++ development environment on Guix System.
I'm using Emacs with lsp-mode and emacs-ccls. This setup works very well for C projects, but ccls doesn't seem to like anything related to C++. Take this simple program for example: --8<---------------cut here---------------start------------->8--- #include <iostream> int main () { std::cout << "Hello, World!\n"; return 0; } --8<---------------cut here---------------end--------------->8--- Both lsp-mode and eglot tell me that ccls reports: "no member named 'cout' in namespace 'std'". I have gcc-toolchain installed and I can compile the project just fine. I tried using bear to generate a compile_commands.json, from this simple Makefile: --8<---------------cut here---------------start------------->8--- all: g++ main.cpp -o main --8<---------------cut here---------------end--------------->8--- but ccls still fails to recognize the members of the std namespace. Irony seems to fail too (same problem), but I haven't tried playing with it too much, I just tested the default Doom Emacs config. One more thing: ccls also complains about this, and I don't know what to make of it: main.cpp error:20 unknown type name '_GLIBCXX17_DEPRECATED' Do any of you have experience with setting up a C++ development environment on Guix System in Emacs? Did you run into similar problems, and if yes, how did you solve them? Cheers, Alexandru-Sergiu Marton
