<h1 class="section">Compilers and Options</h1> <p>Some systems require unusual options for compilation or linking that the <code>configure</code> script does not know about. You can give <code>configure</code> initial values for variables by setting them in the environment. Using a Bourne-compatible shell, you can do that on the command line like this: </p> <div class="example"> <pre class="example">CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
</pre>
</div> <p>On systems that have the <code>env</code> program, you can do it like this: </p> <div class="example"> <pre class="example">env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
</pre>
</div> <p>The configuration process uses GCC to build Bash if it is available. </p><div class="_attribution">
