title: Installing STAR aligner on macOS Big Sur
body: <p>I have been trying to run the make command and keep getting error codes. I have installed gcc with homebrew. When I run the code from github</p>
  <p>if I use</p>
  <pre><code>make STARforMacStatic CXX=/usr/bin/gcc
  </code></pre>
  <p>I get the following error</p>
  <pre><code>date: illegal option -- -
  usage: date [-jnRu] [-d dst] [-r seconds] [-t west] [-v[+|-]val[ymwdHMS]] ... 
              [-f fmt date | [[[mm]dd]HH]MM[[cc]yy][.ss]] [+format]
  /usr/bin/gcc -c   -O3 -std=c++11 -fopenmp -D'COMPILATION_TIME_PLACE=&quot; :/Users/elizabethbonner/STAR-2.7.9a/source&quot;' -D'COMPILE_FOR_MAC' -pipe -Wall -Wextra SoloFeature_collapseUMI_Graph.cpp
  clang: error: unsupported option '-fopenmp'
  make: *** [SoloFeature_collapseUMI_Graph.o] Error 1
  </code></pre>
  <p>I am sure I am missing something simple</p>
