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]
89 Additional options are accepted for compatibility with other
90 configure-script calling conventions, but don't do anything yet:

93 --host=<cpu>-<vendor>-<os> Currently ignored

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 ${PROJECT} easier for you to
188 We'll now investigate your system to verify that all required
189 dependencies are available:
195 if pkg-config --version > /dev/null 2>&1; then
201 printf "Checking for talloc development files... "
202 if pkg-config --exists talloc; then
205 talloc_cflags=$(pkg-config --cflags talloc)
206 talloc_ldflags=$(pkg-config --libs talloc)
211 errors=$((errors + 1))
214 printf "Checking for libelf... "
215 printf "#include <gelf.h>\nint main(void){return elf_version (EV_CURRENT);}\n" > elf-minimal.c
216 if ${CC} -o elf-minimal elf-minimal.c -lelf > /dev/null 2>&1
227 errors=$((errors + 1))
229 rm -f elf-minimal elf-minimal.c
231 if [ $errors -gt 0 ]; then
234 *** Error: The dependencies of ${PROJECT} could not be satisfied. You will
235 need to install the following packages before being able to compile
239 if [ $have_talloc -eq 0 ]; then
240 echo " The talloc library (including development files such as headers)"
241 echo " http://talloc.samba.org/"
244 if [ $have_libelf -eq 0 ]; then
245 echo " The libelf library (including development files such as headers)"
246 echo " http://http://sourceforge.net/projects/elftoolchain/"
250 With any luck, you're using a modern, package-based operating system
251 that has all of these packages available in the distribution. In that
252 case a simple command will install everything you need. For example:
254 On Debian and similar systems:
256 sudo apt-get install libtalloc-dev libelf-dev
258 Or on Fedora and similar systems:
260 sudo yum install libtalloc-devel libelf-devel
262 On other systems, similar commands can be used, but the details of the
263 package names may be different.
266 if [ $have_pkg_config -eq 0 ]; then
268 Note: the pkg-config program is not available. This configure script
269 uses pkg-config to find the compilation flags required to link against
270 the various libraries needed by ${PROJECT}. It's possible you simply need
271 to install pkg-config with a command such as:
273 sudo apt-get install pkg-config
275 sudo yum install pkgconfig
277 But if pkg-config is not available for your system, then you will need
278 to modify the configure script to manually set the cflags and ldflags
279 variables to the correct values to link against each library in each
280 case that pkg-config could not be used to determine those values.
285 When you have installed the necessary dependencies, you can run
286 configure again to ensure the packages can be found, or simply run
293 printf "int main(void){return 0;}\n" > minimal.c
296 printf "Checking for available C compiler warning flags... "
297 for flag in -Wall -Wextra -Wmissing-declarations; do
298 if ${CC} $flag -o minimal minimal.c > /dev/null 2>&1
300 WARN_CFLAGS="${WARN_CFLAGS}${WARN_CFLAGS:+ }${flag}"
303 printf "\n\t${WARN_CFLAGS}\n"
305 rm -f minimal minimal.c
309 All required packages were found. You may now run the following
310 commands to compile and install ${PROJECT}:
317 # construct the Makefile.config
318 cat > Makefile.config <<EOF
319 # This Makefile.config was automatically generated by the ./configure
320 # script of ${PROJECT}. If the configure script identified anything
321 # incorrectly, then you can edit this file to try to correct things,
322 # but be warned that if configure is run again it will destroy your
323 # changes, (and this could happen by simply calling "make" if the
324 # configure script is updated).
