51 This script configures ${PROJECT} to build on your system.
53 It verifies that dependencies are available, determines flags needed
54 to compile and link against various required libraries, and identifies
55 whether various system functions can be used or if locally-provided
56 replacements will be built instead.
58 Finally, it allows you to control various aspects of the build and
61 First, some common variables can specified via environment variables:
63 CC The C compiler to use
64 CFLAGS Flags to pass to the C compiler
65 LDFLAGS Flags to pass when linking
67 Each of these values can further be controlled by specifying them
68 later on the "make" command line.
70 Additionally, various options can be specified on the configure
73 --prefix=PREFIX Install files in PREFIX [$PREFIX]
75 By default, "make install" will install the resulting program to
76 $PREFIX/bin, documentation to $PREFIX/man, etc. You can
77 specify an installation prefix other than $PREFIX using
78 --prefix, for instance:
80 ./configure --prefix=\$HOME
82 Fine tuning of some installation directories is available:
84 --bindir=DIR Install executables to DIR [PREFIX/bin]
85 --libdir=DIR Install libraries to DIR [PREFIX/lib]
86 --mandir=DIR Install man pages to DIR [PREFIX/share/man]
87 --sysconfdir=DIR Read-only single-machine data [PREFIX/etc]

175 Welcome to ${PROJECT}, ${PROJECT_BLURB}
177 We hope that the process of building and installing ${PROJECT} is quick
180 If anything goes wrong in the configure process, you can override any
181 decisions it makes by manually editing the Makefile.config file that
182 it creates. Also please do as much as you can to figure out what could
183 be different on your machine compared to those of the ${PROJECT}
184 developers. Then, please email those details to the ${PROJECT} developers so
185 that they can hopefully make future versions of ${PROJECT} easier for you to

414 With any luck, you're using a modern, package-based operating system
415 that has all of these packages available in the distribution. In that
416 case a simple command will install everything you need. For example:
418 On Debian and similar systems:
420 sudo apt-get install libtalloc-dev libelf-dev \\
421 libgl1-mesa-dev libgles2-mesa-dev
423 Or on Fedora and similar systems:
425 sudo yum install libtalloc-devel libelf-devel \\
426 mesa-libGL-devel mesa-libGLES-devel
428 On other systems, similar commands can be used, but the details of the
429 package names may be different.
431 When you have installed the necessary dependencies, you can run
432 configure again to ensure the packages can be found, or simply run
