Installing 32 bit boost libraries in ubuntu?

Question

linux

In general, the task was to connect restsdk to a project in linux to compile a 32-bit library. I compile and this is what comes out

It turns out that he does not find the library, okay. I connect the library using -lboost_system and the output is

[email protected]:~/workbench/ukau-gmod-module$ ./compile.sh 
/usr/bin/ld: skipping incompatible /usr/lib/x86_64-linux-gnu/libboost_system.so when searching for -lboost_system
/usr/bin/ld: skipping incompatible /usr/lib/x86_64-linux-gnu/libboost_system.a when searching for -lboost_system
/usr/bin/ld: cannot find -lboost_system
collect2: error: ld returned 1 exit status

I understand that the libraries are 64 bit. Tell me how to fix the situation?

Answer 1

Add i386 architecture.
Install the libboost-all-dev:i386 package or only the necessary devs with the architecture.
Most likely you will also need the gcc-multilib package.
Add the -m32

Answer 2

You didn't specify a distribution.
but they said for a long time
