#1563 Failed to configure Codeblocks (and to build) against boost-1.89.0

[band-a-prend]

The Codeblocks-25.03 and r13749 failed to configure with system boost-1.89.0 due to it have no boost_system library and can't be linked it anymore [1].

When trying to configure to build codeblocks with contrib-plugins=all (i.e. with NassiShneiderman plugin enabled) then the checking of boost_system library is done within m4/ax_boost_system.m4 and as boost_system is absent in boost-1.89.0 the configuration error appears:

...
checking for boostlib >=  (102000)... yes
checking whether the Boost::System library is available... yes
configure: error: Could not find a version of the library!

(see e.g. Gentoo issue [2] attached file "dev-util:codeblocks-25.03-r1:20251014-135640.log")

The configuration string that was used (e.g. for Gentoo dev-util/codeblocks-9999.ebuild, i.e. for codeblocks r13749 at the moment of issue report):

./configure --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --datarootdir=/usr/share --disable-dependency-tracking --disable-silent-rules --disable-static --docdir=/usr/share/doc/codeblocks-9999 --htmldir=/usr/share/doc/codeblocks-9999/html --with-sysroot=/ --libdir=/usr/lib64 --disable-pch --disable-static --disable-debug --with-boost-libdir=/usr/lib64 --with-contrib-plugins=all

Apart from everything else is NassiShneiderman plugin required to be linked against boost and especially against boost_system library? Does it require headers only?

The boost_system was added in https://sourceforge.net/p/codeblocks/code/11186/ and https://sourceforge.net/p/codeblocks/code/11227/ to fix Gentoo build against boost-1.65 and some later.

Looks like boost_syetem is now integrated in C++11, it should not be difficult getting rid of it in the plugin.

I see in NassiShneiderman plugin sources the boost mention only in CParcer.cpp

#include <boost/spirit/include/classic.hpp>
#include <boost/spirit/include/classic_core.hpp>
#include <boost/spirit/include/classic_symbols.hpp>
#include <boost/spirit/include/classic_confix.hpp>
using namespace boost::spirit::classic;

and in parserules.h

#include <boost/spirit/core.hpp>
#include <boost/spirit/symbols/symbols.hpp>
#include <boost/spirit/utility/chset.hpp>
#include <boost/spirit/utility/escape_char.hpp>
#include <boost/spirit/utility/confix.hpp>
using namespace boost::spirit;

And it seems that boost::spirit is header only library.

[Miguel Gimenez]

Boost_system library removed from the Linux projects in [r13751].

Autotools part will come later (help with autotools is welcome).

[Miguel Gimenez]

Autotools should be fixed in [r13752], can you check it?

Thank you.

[band-a-prend]

Thanks! At r13752 Codeblocks with NassiShneiderman plugin is successsfully compiled with boost-1.89. 0.

Maybe an additional NassiShneiderman autotools cleanup will be useful (see attached patch). Please note that m4/ax_boost_system.m4 is removed here too!

I will delete the other stuff if nobody complaints in a reasonable time frame.
