solve the errors building llama.cpp

[Mezca1]

when cmd shows that

python setup_env.py -md models/BitNet-b1.58-2B-4T -q i2_s
INFO:root:Compiling the code using CMake.
ERROR:root:Error occurred while running command: Command '['cmake', '--build', 'build', '--config', 'Release']' returned non-zero exit status 1., check details in logs\compile.log

you can add #include in \BitNet\3rdparty\llama.cpp\common\common.cpp

Can you show logs\compile.log file here ?

Had the same problem, used Mingw instead of visual studio, check this out and let me know if it helps. https://github.com/saifxyzyz/Bitnet-Mingw.git

Nope it doesn't helps. It just straight fork but without changes.

The only fatal error in the log is:
common.cpp(445,32): error : no type named 'system_clock' in namespace 'std::chrono'
common.cpp(447,11): error : 'clock' is not a class, namespace, or enumeration

Root Cause
common.cpp uses std::chrono::system_clock (C++11) but the translation unit does not contain #include , so clang-cl on Windows cannot find the definition.

Impact
Only llama-common.lib fails to build; all subsequent executables (including run_inference) cannot link, so the entire BitNet pipeline is blocked.

One-Click Fix (pick either)
Method 1: Add the missing header locally (fastest, no upstream wait)
Open
~\BitNet\3rdparty\llama.cpp\common\common.cpp
add:
#include

If that so it should be failed build by all platform then.
Problem should be that windows is handling clang natively different than other platforms. But using wsl this issue is not happening.

So, the easiest solution is to use wsl for building and running it.

By the way I run it on wsl in windows 10.
Because setting clang in windows is quite headache for me.

I added #include , but it does not work. Same error:

ERROR:root:Error occurred while running command: Command '['cmake', '--build', 'build', '--config', 'Release']' returned non-zero exit status 1., check details in logs\compile.log.

I get several warnings and the following error:
...\BitNet\3rdparty\llama.cpp\common\log.cpp(28,79): error : no member named 'system_clock' in namespace 'std::chrono' [...\BitNet\build\3rdparty\llama.cpp\common\common.vcxproj]

[GMP2475]

Just completed to compile. I solved adding in CMakeLists.txt:
set(CMAKE_CXX_STANDARD 17) # this one
set(CMAKE_CXX_STANDARD_REQUIRED true)

and various #include. in servela files as indicated by the logs\compile.log

To fix build error do this

🧩 Fix: setup_env.py Compilation Error

If you face errors related to missing <chrono>, you need to modify the following files in the llama.cpp dependency.

Reference Commit:
tinglou/llama.cpp@4e3db1e

Add this line to each affected file:

#include <chrono>

Fixes the problem.

I had the same issue on Windows 11 and came to the same conclusion as farman-mk, that fixes it.
