undefined reference to `boost::locale::ios_info::get(std::ios_base&)'

[nlogozzo]

I'm having an issue getting my code to compile using boost::locale. I have the library built using flatpak:

{
	    "name": "boost",
	    "buildsystem": "simple",
	    "build-commands": [
		"./bootstrap.sh --prefix=/app --with-libraries='system multiprecision locale'",
		"./b2 -j $FLATPAK_BUILDER_N_JOBS install"
	    ],
	    "sources": [
		{
		    "type": "archive",
		    "url": "https://boostorg.jfrog.io/artifactory/main/release/1.80.0/source/boost_1_80_0.tar.bz2",
		    "sha256": "1e19565d82e43bc59209a168f5ac899d3ba471d55c7610c677d4ccf2c9c500c0"
		}
	    ]
},

and am using the library as such:

#include "moneyhelpers.hpp"
#include <sstream>
#include <boost/locale.hpp>

std::string MoneyHelpers::boostMoneyToLocaleString(boost::multiprecision::cpp_dec_float_50 amount, const std::locale& locale)
{
    std::stringstream builder;
    builder.imbue(locale);
    builder << boost::locale::as::currency << amount;
    return builder.str();
}

However, when I try to build and run the application, I'm getting this undefined reference error:

moneyhelpers.cpp:(.text+0x23d): undefined reference to `boost::locale::ios_info::get(std::ios_base&)'
/usr/lib/gcc/x86_64-unknown-linux-gnu/12.1.0/../../../../x86_64-unknown-linux-gnu/bin/ld: moneyhelpers.cpp:(.text+0x24a): undefined reference to `boost::locale::ios_info::display_flags(unsigned long)'

Any help would be greatly appreciated as I cannot find any information on boost::locale::ios_info

It looks like your are not linking to Boost.Locale. Check the link command to verify.
Also "./bootstrap.sh --prefix=/app --with-libraries='system multiprecision locale'", has a mistake which may explain this:

--with-libraries should be a comma-separated list, i.e. --with-libraries=system,multiprecision,locale and as multiprecision is header-only this will error so you have to remove it yielding "./bootstrap.sh --prefix=/app --with-libraries=system,locale",

Let me know if that solves your issue.
