Cocos2d-x: zapcc ready! Using zapcc with CMake build

Editors and Tools
#1

I recently found zapcc: superfast clang-based C/C++ compiler and checked it with cocos2d-x and it works perfectly! Zapcc is

  • 2-4x faster than clang on first build
  • 20-50x faster than clang on cached build

It is quite impressive, isn’t it? There is guide how to use it with cmake build:

  1. Install it from binary package or source code: download from https://www.zapcc.com/ or get using git:

git clone https://github.com/yrnkrn/zapcc.git

  1. Run cmake with addicional arguments:

-DCMAKE_CXX_COMPILER=zapcc++ -DCMAKE_C_COMPILER=zapcc

P.S.: zapcc++ is symlink to zapcc but act a bit different way (addictional linkage flags).
Enjoy fast builds!

UPD: you may notice huge memory usage. In this case:

  1. Find file named zapccs.config in directory, where all other zapcc binaries are installed.
  2. Change value in [MaxMemory] directive to something smaller (to co-cexist with other programs on 8GB ond four CPU cores I personally use 512). This value is in MBs.

zapcc requires more RAM than clang:

@v2003 How much RAM do you have?

#3

8GB (have some plans abuot upgrading to 16GB, but not critical). In file zapccs.config (in binary directory, near all other zapcc executables) there is a value named [MaxMemory]. By deafult, it is set to 1000. For comfort builds on my linux (with chrome, KDevelop and few other greedy programs) in four threads (for 4 CPU cores) I reduce it to 512 (MB).

#4

Have you tried to use this on any other platforms besides Linux?

#5

Unfortunately, I didn’t. But I’ll be glad if someone will do it! Process should be really simillar.

#6

I’d be happy to try on macOS

#7

From Github README:

Which operating systems is supported?
zapcc builds on Linux x64, Visual C++, mingw-w64 and MacOS. It was thoroughly tested on Linux x64 only, the rest are experimental.
