Support #690
Updated by Daniel Curtis over 8 years ago
Every once in a while I need to compile a program with GCC, instead of the default FreeBSD compiler Clang. To accomplish this I install the latest GCC and set it over Clang with environment variables.
* Install GCC:
<pre>
pkg install gcc49
</pre>
#* (Optional) Install GCC from the ports tree:
<pre>
cd /usr/port/lang/gcc49
make install clean
</pre>
* Set the CC, CXX, and CPP environment variables to use GCC:
<pre>
setenv CC gcc49
setenv CXX g++49
setenv CPP cpp49
</pre>
#* (Optional) Environment variables can be set at build time:
<pre>
env CC="gcc49" CXX="g++49" CPP="cpp49" CFLAGS="-std=c++11" make
</pre>
