Berkeley DB

Changing Compile or Load Options

You can specify compiler and/or compile and load time flags by using environment variables during Berkeley DB configuration. For example, if you want to use a specific compiler, specify the CC environment variable before running configure:

prompt: env CC=gcc ../dist/configure 

Using anything other than the native compiler will almost certainly mean that you’ll want to check the flags specified to the compiler and loader, too.

To specify debugging and optimization options for the C compiler, use the CFLAGS environment variable:

prompt: env CFLAGS=-O2 ../dist/configure 

To specify header file search directories and other miscellaneous options for the C preprocessor and compiler, use the CPPFLAGS environment variable: ...
