Trouble with installation dealii v9.6.1 on Mac: C++17 support is disabled.

[akash ahmed]

Dear all,

My MacBook Pro has a chip Apple M2 max and macOS Sonoma,

Apple clang version 16.0.0 (clang-1600.0.26.6)

cmake version 3.31.2. However, I got the following error:

./candi.sh -j 8 --packages="dealii"

-- This is CMake 3.31.3

It would be a great help if you please share your thoughts on resolving this issue. 

Thank you in advance.

We saw this lately.

The problem was that, for whatever reason, the Xcode compiler toolchain
forgot to install the C++ standard library (clang/llvm's libc++).


Can you try reinstalling the toolchain as described here?

Would you mind to post the file

<build directory>/CMakeFiles/CMakeConfigureLog.yaml ?

Happy New Year,
Matthias

Dear Dr. Maier:

Sure, please find it attached to this email.

Thank you

It picks up the correct compiler:

/Library/Developer/CommandLineTools/usr/bin/c++

But then all of the copmiler invocations fail with something like:

ld: library not found for -lc++

This looks like that the C++ standard library (which is called libc++
for clang/llvm) is not installed properly.



Are you able to compile a simple hello world by hand? hello_world.cpp:

#include <iostream>
int main() { std::cout << "Hello World!" << std::endl; }

(If yes, did you use the compiler at
/Library/Developer/CommandLineTools/usr/bin/c++ ?)



Can you uninstall the "CommandLineTools" package, make sure that the
directory is completely removed, and reinstall? (This fixed a similar
issue lately for us.)



Best,
Matthias

Dear Dr. Maier:

Good evening. Yes, I could compile the hello_world.cpp program with g++ and it works. Then

I uninstalled the "CommandLineTools" package and removed with sudo rm -rf /Library/Developer/CommandLineTools

Again, I installed homebrew which installed the Xcode.

Then installed with

./candi.sh -j 8 --packages="hdf5 p4est trilinos dealii"

and unfortunately, encountered the same issue. 

Thank you

Dear all,

The problem is resolved. Here is what I have done:

Upgraded the xcode, cmake and macOS then restarted the computer.

./candi.sh -j 8 --packages="hdf5 p4est trilinos dealii"

However, ended with exit 2, which was different from the previous (exit 1).

Remove hdf5 and run as below:

./candi.sh -j 8 --packages="p4est trilinos dealii"

Thank you for your support.
