64-bit Ubuntu compiled 32-bit program

If you encounter the need to emulate a 32-bit system when using the C4 gadget, we find that the compile prompt error after using the-m32 parameter is as follows:

/usr/bin/ld1 exit status

The first thing to do is to turn on 32-bit support for 64-bit systems

Step one: Confirm that 64 is the kernel of the architecture

Dpkg--print-architecture

Output:
Adm64

Description already has a 64-bit architecture kernel.

Step two: Confirm that the multi-schema support feature is turned on

Dpkg--print-foreign-architectures

Output:
I386

The description is turned on if you do not need to open it manually

Open Multi-schema support

sudo dpkg--add-architecture i386sudo apt-get updatesudo apt-get Dist-upgrade

And so you have 64-bit system support for 32-bit

followed by the installation of GCC Multilab

Install gcc-multilib g++-multilib
