Hi,
for my problem with the m4 macros for boost I think I can go the
following way:
I provide ac_boost_base.m4 which does the version check and defines
BOOST_CPPFLAGS, BOOST_LDFLAGS.
Boost users who only want use the template libs from boost have only to
include this macro.
Boost users who want use the compiled libraries like date_time,
program_options, thread... have to call AX_BOOST_BASE first and
afterward the special macros like AX_BOOST_DATE_TIME,
AX_BOOST_PROGRAM_OPTIONS...
At that time the include/linker flags are already known and we can try
to compile and link a small program with the special library.
configure.ac could look like:
AX_BOOST_BASE([1.33.1])
AX_BOOST_PROGRAM_OPTIONS
AX_BOOST_DATE_TIME
configure --help
gives now
...
--with-boost[=DIR]
use boost (default is No) , specify the root
directory for boost library (optional)
--with-boost-program-options
use the program options library from boost,
requires
a preceding call to AX_BOOST_BASE
--with-boost-date-time use the Date_Time library from boost,
requires a
preceding call to AX_BOOST_BASE
The user can call configure for example:
./configure --with-boost=/opt/boost --with-boost-program-options
I uploaded http://randspringer.de/boost/shared_ptr-0.2.tar.gz as tiny
example.
Any thoughts ?
