| To use the bundled libc++ please add the following LDFLAGS: | |
| LDFLAGS="-L/usr/local/opt/llvm/lib -Wl,-rpath,/usr/local/opt/llvm/lib" | |
| llvm is keg-only, which means it was not symlinked into /usr/local, | |
| because macOS already provides this software and installing another version in | |
| parallel can cause all kinds of trouble. | |
| If you need to have llvm first in your PATH run: | |
| echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> ~/.bash_profile |
