src/MLMLOSEM.cxx:91:2: error: use of undeclared identifier 'random_shuffle'

[DAMPELB]

I try to install Megalib, but at the process of compiling, I face this problem:

src/MLMLOSEM.cxx:91:2: error: use of undeclared identifier 'random_shuffle' random_shuffle(m_Storage.begin(), m_Storage.end());

From the internet, they told me "random_shuffle" was not supported by C11 and C17 What should I do.

Thanks.

Hello,

Can you let me know which OS and which MEGAlib branch you are using? This is usually working.

Best, Andreas

Thanks for your reply, The system is macOS Monterey(12.0.1), and the version of MEGAlib is MEGAlib_v4-alpha. Now, I change the code of MLMLOSEM.cxx, you can see below, I change the function of random_shuffle() to shuffle() which is supported by Xcode13.1 and CLT 13. And then it can be compiled and successfully installed. But actually, I don't know the influence after changing the function. Thanks.

void MLMLOSEM::Shuffle() { //random_shuffle(m_Storage.begin(), m_Storage.end());

random_device rd;
mt19937 g(rd());
shuffle(m_Storage.begin(), m_Storage.end(), g);

}

Thanks. I fixed it in MEGAlib_v4-alpha. Can you check?

[DAMPELB]

Yes, I have checked, It can be install successfully on my laptop. Thanks.

But I also face another Problem. When I install MEGAlib(same version with above) on other computer(MacMini with M1 chip and same system version with above), It shows the problem below:

ld: file not found: @rpath/libgcc_s.1.1.dylib for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

But I have install gcc11 on MacMini by "brew install gcc", and I have checked the lib of "libgcc_s.1.1.dylib" is there. I don't know why they can not find the lib.... Looking forward your answer.

Thanks very much.
