Add some autoconf helper macros for checking for libraries Most checks for libraries take the same format * --with-libFOO=yes|no|check|/some/path argument * check for a function NNN in libFOO.so * check for a header file DDD/HHH.h * Define a WITH_FOO config.h symbol * Define a WITH_FOO make conditional * Substitute FOO_CFLAGS and FOO_LIBS make variables * Print CFLAGS & LIBS summary at the end Doing all this correctly is rather difficult, typically done by copy+paste of a previous usage. Further small improvements people make are not applied to all previous usages. Improve this by creating some helper macros to apply good practice. First, to perform the actual checks: LIBVIRT_CHECK_LIB([SELINUX], [selinux], [getfilecon], [selinux/selinux.h]) This checks for 'getfilecon' in -lselinux, and the existence of 'selinux/selinux.h' header file. If successful it sets SELINUX_CFLAGS and SELINUX_LIBS. The WITH_SELINUX config.h macro and WITH_SELINUX make conditional are also defined. In some cases we need to check two variants of the same library LIBVIRT_CHECK_LIB_ALT([SASL], [sasl2], [sasl_client_init], [sasl/sasl.h], [SASL1], [sasl], [sasl_client_init], [sasl/sasl.h]) This checks for sasl_client_init in libsasl2, and if that is not found, checks sasl_client_init in libsasl. If the first check succeeds WITH_SASL is set, while if the second check succeeds *both* WITH_SASL and WITH_SASL1 are set. If the library supports pkg-config, then another variant is available LIBVIRT_CHECK_PKG([AVAHI], [avahi-client], [0.6.0]) This checks for avahi-client >= 0.6.0 via pkg-config and sets WITH_AVAHI if found.

dnl virt-lib.m4: Helper macros for checking for libraries
dnl
build: use --with-systemd-daemon as configure option Commit 68954fb added a configure option --with-systemd_daemon, which violates the conventions of configure files preferring dash in all option names. This fixes it, before we hit a release where the tarball is baked with an awkward name. * m4/virt-lib.m4 (LIBVIRT_CHECK_LIB, LIBVIRT_CHECK_LIB_ALT) (LIBVIRT_CHECK_PKG): Favor - over _ in configure option names.

m4/virt-lib: add new parameter to override default fail action This allows to use two or more LIBVIRT_CHECK_(LIB|LIB_ALT|PKG) macros for one library. For example, when we check for existence of pgk-config file of some library and we know that not all versions of that library that libvirt requires provides this file, we can fallback to use library check.

Add some autoconf helper macros for checking for libraries Most checks for libraries take the same format * --with-libFOO=yes|no|check|/some/path argument * check for a function NNN in libFOO.so * check for a header file DDD/HHH.h * Define a WITH_FOO config.h symbol * Define a WITH_FOO make conditional * Substitute FOO_CFLAGS and FOO_LIBS make variables * Print CFLAGS & LIBS summary at the end Doing all this correctly is rather difficult, typically done by copy+paste of a previous usage. Further small improvements people make are not applied to all previous usages. Improve this by creating some helper macros to apply good practice. First, to perform the actual checks: LIBVIRT_CHECK_LIB([SELINUX], [selinux], [getfilecon], [selinux/selinux.h]) This checks for 'getfilecon' in -lselinux, and the existence of 'selinux/selinux.h' header file. If successful it sets SELINUX_CFLAGS and SELINUX_LIBS. The WITH_SELINUX config.h macro and WITH_SELINUX make conditional are also defined. In some cases we need to check two variants of the same library LIBVIRT_CHECK_LIB_ALT([SASL], [sasl2], [sasl_client_init], [sasl/sasl.h], [SASL1], [sasl], [sasl_client_init], [sasl/sasl.h]) This checks for sasl_client_init in libsasl2, and if that is not found, checks sasl_client_init in libsasl. If the first check succeeds WITH_SASL is set, while if the second check succeeds *both* WITH_SASL and WITH_SASL1 are set.
