The Telegram client library subcomponent requires relatively large amount of RAM to build by default (3.5GB using g++, and 1.5 GB for clang++). It is possible to adjust the Telegram client library source code so that it requires less RAM (but takes longer time). Doing so reduces the memory requirement to around 1GB under g++ and 0.5GB for clang++.
Steps to build nchat on a low memory system:
Extra Dependencies (Linux)
sudo apt install php-cli clang
Source
git clone https://github.com/d99kris/nchat && cd nchat
Setup
mkdir -p build && cd build
CC=/usr/bin/clang CXX=/usr/bin/clang++ cmake ..
Split source (optional)
cmake --build . --target prepare_cross_compiling
cd ../lib/tgchat/ext/td ; php SplitSource.php ; cd -
Build
make -s
Install
sudo make install
Revert Source Code Split (Optional)
cd ../lib/tgchat/ext/td ; php SplitSource.php --undo ; cd -
Source
git clone https://aur.archlinux.org/nchat-git.git && cd nchat-git
Prepare
Open PKGBUILD in your favourite editor.
Add `php` and `clang` on depends array.
Change the `_install_mode` to `slow`.
