Article #369: How Do I Compile FLTK?
Created at 10:59 Jan 29, 2005 by mike
In most cases you can just type "make". This will
run configure with the default of no options and then compile
FLTK uses GNU autoconf to configure itself for your UNIX platform.
The main things that the configure script will look for are the X11 and
OpenGL (or Mesa) header and library files. If these cannot be found in
the standard include/library locations you'll need to define the
CFLAGS, CXXFLAGS, and LDFLAGS environment
variables. For the Bourne and Korn shells you'd use:
CFLAGS=-Iincludedir; export CFLAGS
CXXFLAGS=-Iincludedir; export CXXFLAGS
LDFLAGS=-Llibdir; export LDFLAGS
For C shell and tcsh, use:
setenv CFLAGS "-Iincludedir"
setenv CXXFLAGS "-Iincludedir"
setenv LDFLAGS "-Llibdir"
By default configure will look for a C++ compiler named
CC, c++, g++, or gcc in that
order. To use another compiler you need to set the CXX
CXX=xlC; export CXX
setenv CXX "xlC"
The CC environment variable can also be used to
override the default C compiler (cc or gcc),
which is used for a few FLTK source files.
You can run configure yourself to get the exact setup you
need. Type "./configure <options>", where
<DD>Enable debugging code & symbols</DD>
<DD>Enable generation of shared libraries</DD>
<DD>Set the location for executables [default = /usr/local/bin]</DD>
<DD>Set the location for include files. [default = /usr/local/include]</DD>
<DD>Set the location for libraries [default = /usr/local/lib]</DD>
<DD>Set the location for man pages [default = /usr/local/man]</DD>
<DD>Set the directory prefix for files [default = /usr/local]</DD>
When the configure script is done you can just run the
"make" command. This will build the library, FLUID
tool, and all of the test programs.
To install the library, become root and type "make
install". This will copy the "fluid" executable
to "bindir", the header files to
"includedir", the library files to "libdir",
the man pages to "mandir", and the documentation files to the
documentation directory - usually /usr/local/share/doc/fltk.
