Hi Davo!
Appreciate the reply.
It's installed. Based on calling the gcc version in terminal:
gcc -v
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 10.0.1 (clang-1001.0.46.4)
Target: x86_64-apple-darwin18.7.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
I'm considering this problem has to do with which clang I'm using and how it's setup???
I initially installed clang6. Couldn't install rugarch. So then I went through the posts I pasted previously, which recommended trying clang 4, so I also installed that.
The error indicates the output directory can't be found:
/usr/local/clang4/bin/clang++
I went and checked in Finder, and indeed there is no 'bin' folder in /usr/local/clang4
However, I did find it in /user/local/clang6. Full path to /bin/clang++.
