/usr/lib/libstdc++.6.dylib: mach-o, but wrong architecture

问题:

I've just update my MAC OS Mountain Lion's compiler to gcc 4.8.1, the configure & install process is:

./configure --prefix=/usr make sudo make install 

the GCC 4.8.1 was installed completely, but then I found I cannot open my Chrome, as well as several other programs. I've check the error report, the most important information is:

Dyld Error Message:     Library not loaded: /usr/lib/libstdc++.6.dylib     Referenced from: /Applications/Google Chrome.app/Contents/MacOS/Google Chrome     Reason: no suitable image found.  Did find:     /usr/lib/libstdc++.6.dylib: mach-o, but wrong architecture     /usr/lib/libstdc++.6.dylib: mach-o, but wrong architecture 

So what should I do to solve this? Recompile GCC with proper architecture? But how to do this?

回答1:

You have overwritten several system libraries with incompatible versions. You will need to reinstall Mac OS X.

Don't install software with --prefix=/usr. That prefix is reserved for software distributed with the operating system. Use /usr/local for software you install yourself. You may want to try Homebrew instead once you've reinstalled.

Since libstdc is deprecated and removed in iOS12, you need to update your dependencies to use libc++ or manually add libstdc. For manually adding refer this - answer
