hptt on apple silicon

[pcchen]

I try to git clone and compile hptt on apple silicon.

If I use cmake

export CC=/opt/homebrew/bin/gcc-14
export CXX=/opt/homebrew/bin/g++-14
cmake -S . -B build
cmake --build build

then I got this error

[ 20%] Building CXX object CMakeFiles/hptt.dir/src/hptt.cpp.o

If I just use the Makefile provided by hptt, it works

hptt % make

If I try to turn on arm with Makefile, it fails.

hptt % make arm
/Applications/Xcode.app/Contents/Developer/usr/bin/make clean
rm -rf ./src/hptt.o ./src/plan.o ./src/transpose.o ./src/utils.o ./src/hptt.so ./src/plan.so ./src/transpose.so ./src/utils.so lib/libhptt.so lib/libhptt.a

This is an upstream issue. But if we want to include hptt as submodulus, we need a way to handle this problem.

Currently we are using a fork of hptt from @kaihsin. Updating Cmake scripts might fix this.

[kaihsin]

Yes. I think there are some treak need to be done so I forked it. Lmk if you need to have access

[yingjerkao]

There is a PR for this at the original repo
springer13/hptt#35

[IvanaGyro]

I forked HPTT to Cytnx organization, and created a PR for merging that PR at the original repo. Cytnx-dev/hptt#1 But I don't know why I don't have permission to solve the conflicts of that PR in the repo I forked.

I believe the conflict is in the original repo fork. Since your main was forked from @kaihsin's repo, the conflict needs to be resolved at the original springer repo.

Fixed in Cytnx-dev/hptt#1 and Cytnx-dev/hptt#2

[IvanaGyro]

#636 switches HPTT to Cytnx-dev fork.
