Have you ever face 

"clang: error: unsupported option '-fopenmp'"

issue when installing R packages (me is installing ChIPseeker)?

I'm using macOS Sierra and trying to install ChIPseeker via biocLite.

The error message is as below:

clang: error: unsupported option '-fopenmp'
make: *** [coxph.o] Error 1
ERROR: compilation failed for package ‘mgcv’

Thanks! Kylie

  • Do you have OpenMP installed, e.g. `brew install clang-omp` – user1981275 Sep 18 '17 at 07:51
  • Hi Rajesh, thanks. I could not install OpenMP through brew. The error message is as below: Error: No available formula with the name "clang-omp" ==> Searching for a previously deleted formula... Warning: homebrew/core is shallow clone. To get complete history run: git -C "$(brew --repo homebrew/core)" fetch --unshallow Error: No previously deleted formula found. ==> Searching for similarly named formulae... ==> Searching local taps... Error: No similarly named formulae found. ==> Searching taps... ==> Searching taps on GitHub... Error: No formulae found in taps. – Kylie M. Sep 18 '17 at 11:31
