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
188 We'll now investigate your system to verify that all required
189 dependencies are available:

318 With any luck, you're using a modern, package-based operating system
319 that has all of these packages available in the distribution. In that
320 case a simple command will install everything you need. For example:
322 On Debian and similar systems:
324 sudo apt-get install libtalloc-dev libelf-dev \\
325 libgl1-mesa-dev libgles2-mesa-dev
327 Or on Fedora and similar systems:
329 sudo yum install libtalloc-devel libelf-devel \\
330 mesa-libGL-devel mesa-libGLES-devel
332 On other systems, similar commands can be used, but the details of the
333 package names may be different.
336 if [ $have_pkg_config -eq 0 ]; then
338 Note: the pkg-config program is not available. This configure script
339 uses pkg-config to find the compilation flags required to link against
340 the various libraries needed by ${PROJECT}. It's possible you simply need
341 to install pkg-config with a command such as:
343 sudo apt-get install pkg-config
345 sudo yum install pkgconfig
347 But if pkg-config is not available for your system, then you will need
348 to modify the configure script to manually set the cflags and ldflags
349 variables to the correct values to link against each library in each
350 case that pkg-config could not be used to determine those values.
355 When you have installed the necessary dependencies, you can run
356 configure again to ensure the packages can be found, or simply run
363 printf "int main(void){return 0;}\n" > minimal.c
366 printf "Checking for available C compiler warning flags... "
367 for flag in -Wall -Wextra -Wmissing-declarations; do
368 if ${CC} $flag -o minimal minimal.c > /dev/null 2>&1
370 WARN_CFLAGS="${WARN_CFLAGS}${WARN_CFLAGS:+ }${flag}"
373 printf "\n\t${WARN_CFLAGS}\n"
375 rm -f minimal minimal.c
379 All required packages were found.
