./configure hang up #25864

I am using Mac OS 13.0.1

i get to this point everytime everyway I try to configure the code from source....

checking dependency style of g++... gcc3
checking whether g++ supports C++17 features with -std=c++17... yes
checking whether std::filesystem can be used without link library... no
checking whether std::filesystem needs -lstdc++fs... no
checking whether std::filesystem needs -lc++fs... configure: error: in `/bitcoin/bitcoin-cli':
configure: error: cannot figure out how to use std::filesystem
See `config.log' for more details

what can i do to remedy the situation?

You're using an unreleased version of macOS?

What compiler are you using? What is the error in config.log?

There is a macOS 13 beta out. I'm not sure why Apple would call it 13.0.1 while it's still in beta though?

https://developer.apple.com/documentation/macos-release-notes/macos-13-release-notes

I've recently encountered this on MacOs 12.5 I think I needed to install g++8 to get it to work, I see that you have g++3 there. I'm trying to redo my google searches. Did you follow the instructions through the macOS guide and have all the dependencies installed?

you know i actually meant 10.13.6

and yes i have all of the dependecies i thought. with the guide:

using this guide:

i actually meant 10.13.6

using this guide:

There's no need to use (outdated), 2 year old build guides from Medium. Just use our actual build documentation: https://github.com/bitcoin/bitcoin/blob/master/doc/build-osx.md.

In any case, you didn't answer either of the questions we need answers to, to solve your problem: What compiler are you using? What is the error in config.log?. The problem is that your compiler doesn't support using std::filesystem. You can install and use a newer compiler that does. i.e GCC 8.1+ or Clang 8.0+.

how do i go about updating gcc in mac os? with home brew ? i couldnt seem to get it working with brew install gcc@8 but it still recognizes gcc3 and not the new one. how exactly do i install the new compiler?

What is g++ --version (I think on macOS this will just print some clang version, as g++ may be an alias for clang)

Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 10.0.0 (clang-1000.10.44.4)
Target: x86_64-apple-darwin17.7.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

i couldnt seem to get it working with brew install gcc@8

There's no particular reason to use GCC 8. I'd instead suggest llvm, which is currently version 14.0.6. Once installed, pass CC and CXX to configure. i.e:

brew install llvm
./autogen.sh
# where /path/to is something like /opt/homebrew/opt/llvm/bin/clang.
# brew info llvm will show you this.
./configure CC=/path/to/clang CXX=/path/to/clang++
make check

clang ? is that what llvm is?

still getting hung up, why cannot my c++ compiler make executables????

I WAS ABLE TO COMPILE THANK YOU VERY MUCH GUYS!!!

thanks for following up with me till the end.!!!
