"fatal error: 'future' file not found" when make

[Dexter-Wx]

Got error when build llama.cpp on Macbook m1pro (MacOS15.0 beta2):

code in terminal:

git clone https://github.com/ggerganov/llama.cpp
cd llama.cpp
make

the output after make:

dexter@192 /users/dexter/miniforge3/envs/llama.cpp % make
I ccache not found. Consider installing it for faster compilation.

make: *** [ggml/src/ggml-blas.o] Error 1

the 2 solutions I have tried but failed

I search my computer and find the file "future" in "/Library/Developer/CommandLineTools/SDKs/MacOSX15.0.sdk/usr/include/c++/v1"

1. change #include to #include "future" in ggml/src/ggml-blas.cpp
2. make -I /Library/Developer/CommandLineTools/SDKs/MacOSX15.0.sdk/usr/include/c++/v1

I'm not familiar with c++ enough, is there anybody can help me fix the error?

[micsthepick]

perhaps try the following?

mkdir build
cd build
cmake ..
make

[Dexter-Wx]

thanks but still error.

[Dexter-Wx]

Error fixed!
We should save the path of c++ library in environment variable:
export CXXFLAGS=-I/Library/Developer/CommandLineTools/SDKs/MacOSX15.0.sdk/usr/include/c++/v1
Or use another way:
Change a variable in the file "Makefile" of llama.cpp:
add -I/Library/Developer/CommandLineTools/SDKs/MacOSX15.0.sdk/usr/include/c++/v1 behind
MK_CPPFLAGS = -Iggml/include -Iggml/src -Iinclude -Isrc -Icommon

future is part of the C++ standard library, there is something wrong with your build environment if your compiler cannot find it.

[Dexter-Wx]

yes, that's right.

Same error, I fixed it by re-installing CommandLineTools:

sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

It might be because I upgraded CommandLineTools from version 15.0 to 16.0, which caused the error.

It helped me too, thank you :)
