Can I compile on OSX Tahoe?

Is there an existing issue for this?

I have searched the existing issues

Current behaviour

I recently upgraded my OS to Mac OSX Tahoe 26.0.1 (25A362)

Step 1: Success

0git clone ssh://github.com/bitcoin/bitcoin.git

Step 2: Success

0cmake -B build -DENABLE_IPC=OFF -DBUILD_GUI=OFF -DWITH_QRENCODE=OFF

Step 3: Fails

0cmake --build build

The default clang was from homebrew which also failed but then I switched to XCode clang and still fails :joy:

Expected behaviour

Get a compiled bitcoind ❤️

Steps to reproduce

Step 1: Success

0git clone ssh://github.com/bitcoin/bitcoin.git

Step 2: Success

0cmake -B build -DENABLE_IPC=OFF -DBUILD_GUI=OFF -DWITH_QRENCODE=OFF

Step 3: Fails

0cmake --build build

What is the configure summary, before you start to compile? (The output of cmake -B build -DENABLE_IPC=OFF -DBUILD_GUI=OFF -DWITH_QRENCODE=OFF)

What is your XCode version?

You are certainly not using the brew installed boost lib.

What other boost libs are on your system?

@maflcko ran configure again and here’s the output https://gist.github.com/umrashrf/6a63476cce762e00a4f45603837c5bda

I just opened XCode and it asked me to install it. Still fails to build after installation.

@umrashrf

Could you please post the output of the following command:

0rm -rf build && cmake -B build -DENABLE_IPC=OFF -DBUILD_GUI=OFF -DWITH_QRENCODE=OFF -LA 2>&1 | grep -i boost

?

umrashrf commented at 5:42 pm on October 29, 2025: none

@hebasto I first put the output to a file so I can resue it later.

@umrashrf

I have a guess, and to confirm it, I’d ask you to try configuring and building with the additional -DENABLE_WALLET=OFF option.

umrashrf commented at 6:04 pm on October 29, 2025: none

@hebasto tried that but fails.

this is too old, you need at least version 17. Do a general brew upgrade on the system and retry, I have the same OSx, it should work.

umrashrf commented at 10:41 pm on October 29, 2025: none

@l0rinc still fails

brew upgrade
brew reinstall boost
use clang from homebrew (update $PATH)

l0rinc commented at 10:49 pm on October 29, 2025: contributor

Seems the llvm upgrade was successful, but you still have two boost installations, try removing the old one.

umrashrf commented at 5:07 am on October 30, 2025: none

I feel a bit stupid as I just did git pull and it brought some new changes.

Anyway I am still struggling to build successfully. @l0rinc you gave me a good tip. It’s using /usr/local/include/boost/ instead of /opt/homebrew/Cellar/boost/1.89.0/include/boost/

Any idea how can switch boost? I have already tried Boost_ROOT and other variables.

umrashrf commented at 5:54 am on October 30, 2025: none

Oh looks like I made some progress by using:

0rm -rf build
1cmake -B build \
2    -DCMAKE_C_COMPILER=/opt/homebrew/opt/llvm/bin/clang \
3    -DCMAKE_CXX_COMPILER=/opt/homebrew/opt/llvm/bin/clang++ \
4    -DENABLE_IPC=OFF \
5    -DBUILD_GUI=OFF \
6    -DWITH_QRENCODE=OFF \
7    -DENABLE_WALLET=OFF

configure logs: https://gist.github.com/umrashrf/dabd3c476da9fa727add2db1522bf3c7

It failed but with a different error.

umrashrf commented at 6:05 am on October 30, 2025: none

Doing the following fixed the issue!

0export LDFLAGS="-L$(brew --prefix llvm)/lib/c++"
1export CXXFLAGS="-I$(brew --prefix llvm)/include"

Build success 100%
