I’m using a chroot environment to compile my program for 32 bit environments. Using chroot environment through schroot is easy but is there a way to make compiling without using chroot?

Yes, you can use `-m32` option of gcc

In order to be able to compile with `-m32` option, you need multilib gcc and `libc6` development package for i386 platform.

You can install with in Debian based systems like that:

```
sudo apt-get install libc6-i386 gcc-multilib

```

If you want make same on c++, you have to install similar packages for c++ environment like that:

```
sudo apt-get install g++-multilib lib32stdc++-4.9-dev

```

After that you can compile programs with:

```
gcc -m32 -o myprog myprog.c
```
