CMake Error 'functional' file not found

[lotshawpc]

I'm trying to install QCOR on Mac using git pull, mkdir build, cd build, cmake .. -DXACC_BUILD_TESTS=TRUE -DXACC_BUILD_EXAMPLES=TRUE, make -j 48 install

This returns an error at the end of the install

In file included from /Users/5ci/.xacc/include/qcor/qcor_lang_ext.hpp:12: /Users/5ci/.xacc/include/qcor/objective_function.hpp:13:10: fatal error: 'functional' file not found

include

I've tried updating to the latest version of xacc before installing, but this didn't help. Any ideas what is going on?

Usually the 'include functional' not found error is related to not being able to find the xcode command line tools. Make sure you install that, and you might also set the SDKROOT environment variable. check out https://github.com/eclipse/xacc/issues/430

For building from source check out https://aide-qc.github.io/deploy/getting_started/build_from_source/#a-idxqbrewa-xacc-and-qcor-on-mac-os-x-and-linux-x86_64-with-homebrew-not-ubuntu. For example, you wouldn't want to set XACC_BUILD* when running cmake for qcor.

Thanks, Alex! I’ve been able to install qcor after install xcode.

Now I’m trying to run the example program bell.py. The code is below, it is copied from https://aide-qc.github.io/deploy/getting_started/

This returns the following error, any idea what is happening?

python3 bell.py

Failure value returned from cantFail wrapped call

Symbols not found: [ _ ]

UNREACHABLE executed at /usr/local/Cellar/llvm-csp/1.0.0/include/llvm/Support/Error.h:749!

Abort trap: 6

Here’s the program bell.py –

import sys

import os

from pathlib import Path

sys.path.insert(1, str(Path.home()) + '/.xacc')

sys.path.insert(1, str(Path.home()) + '/.qcor')

from qcor import qjit, qalloc, qreg

Define a Bell kernel

@qjit

def bell(q : qreg):

H(q[0])

CX(q[0], q[1])

for i in range(q.size()):

    Measure(q[i])

Allocate 2 qubits

q = qalloc(2)

Run the bell experiment

bell(q)

Print the results

print('Results')

print(q.counts())

Thanks, Phil

Hi, @amccaskey I found same error when I install QCOR on ubuntu 22.04 LST using following command

$ git clone https://github.com/qir-alliance/qcor.git
$ cd qcor && mkdir build && cd build    
$ cmake .. -G Ninja -DLLVM_ROOT=/usr/local/aideqc/llvm
$ cmake --build . --target install

And I get error message when running $ cmake --build . --target install

Any ideas or suggestions? Thanks!!!
