Autotools

Anything about libtoolize, autogen, configure

Basic usage

The default sequence is:

autoreconf -ivf
./configure             # Possibly add things like: --prefix=/usr
make
sudo make install

Configure

Add extra link flags or libraries

To add extra link flags (like location of libraries), use LDFLAGS:

./configure LDFLAGS="-L/path/to/libs"

To add extra libraries, use LDLIBS:

./configure LDLIBS="-lintl -liconv"

• Note: Don't use LDFLAGS to add extra libraries, because it appears before list of source objects, and hence will be ignored by gcc.
• Note: If LDLIBS does not work, try LIBS instead.

Build 32-bit libraries on x86_64

Do the following export before the build recipe (also with cmake):

export LDFLAGS="-32" CXXFLAGS="-32" CFLAGS="-32"
