How to build without CMake ? about td

[levlam]

The best way to answer all questions is to read CMakeLists.txt files.

1. CMakeLists.txt files contains exhaustive description of all source code dependencies. If I try to write them here, I just write CMakeLists.txt from scratch.
2. Section "https://github.com/tdlib/td#using-in-cmake-c-projects" of README.md contains list of targets supposed to be externally used. Choose one and follow its dependencies.
3. It looks like you need Td::TdStatic target.
4. Follow install target described in CMakeLists.txt.
5. Yes. Some source code files are auto-generated. Follow prepare_cross_compiling CMake target to see, how they are generated.
6. You don't need to exclude anything manually. All unneeded OSes specific code (which is localized in tdutils/td/utils/port) will be excluded automatically.

Anyway, I recommend to use CMake, even your project uses another build system, because it will be hard to maintain your own build files. Just specify CMAKE_INSTALL_PREFIX to CMake, compile and install TDLib to local directory, and use prebuilt library in your project.

I understand but I really don't want to build full lib with Cmake, it takes ages (more than 30 min on my very decent machine), and produces a lot of things which I don't need/use. Also using prebuild lib will complicate the build steps and deploy, and source management. On one of my target systems, I'm not even sure to have Cmake available to prebuild lib once.

I'll try to create my Qbs file by extracting information from Cmake for the TdStatic target.

Just a fair warning: do not expect compilation time to be decreased after migration to Qbs.
To build TdStatic means to build almost everything.

Also the build should be much faster than 30min when you are using clang and parallel build with make or ninja.
