AC_PKG_MICO([X.X.X optional required])
1.1.1.1 (2001/07/26) Installed_Packages @ ac-archive-0.5.39
Tal Shalif <tal@shalif.com>
This macro searches for a MICO installation on your system. MICO (Mico Is COrba) installs the file 'mico-setup.sh' under MICO_INSTALL_BASE/lib, where MICO_INSTALL_BASE is probably /usr/local or /usr. If nothing was specified when calling configure or just --with-mico, it searches in $prefix/lib:/usr/local/lib:/usr/lib The argument of s--with-mico specifies the full pathname of the mico-setup.sh file. For instance --with-mico=/usr/local/mico-2.2.6/lib/mico-setup.sh.
If the version argument is given (e.g. 2.2.6), AC_PKG_MICO checks that the mico package is this version number or higher.
The other optional argument to AC_PKG_MICO are 'optional' and 'required'. by default, placing AC_PKG_MICO in your configure.in does not enforce using mico, if it is not found on the system. If MICO existence is critical for the building of your package, then you probably want to specify something like "AC_PKG_MICO(2.2.6 required)". Then, even if the --with-mico was not spcefied on the command line of the configure script, an error will be raised if mico was not found.
If the mico package is not found, abort configuration with error message.
It defines the symbol MICOSETUP, MICOVERSION, MICOSHAREDDIR MICO_INCLUDE, MICO_LIB and MICO_CXX if mico is found. In addition, the mico script mico-c++ (set in (MICO_CXX) is scaned for a string match "-I.*ministl" and if foundMICO_USE_MINISTL is set to 1, otherwise to 0.
Example of use of these variables in your Makefile.in:
INCLUDES += @MICO_INCLUDE@
LDFLAGS += @MICO_LIB@
