Hi everyone,

Have you ever face "clang: error: unsupported option '-fopenmp'" issue when installing ChIPseeker (or other R packages)?

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

Maybe you can try using the following command to install the mgcv package.

## in Terminal
wget -c https://cran.r-project.org/bin/macosx/el-capitan/contrib/3.4/mgcv_1.8-22.tgz
R CMD INSTALL mgcv_1.8-22.tgz
