Compilation Issue #178

Closed jumpy4 closed 1 year ago

jumpy4 commented 1 year ago

Hi.

I'm trying to compile the program on Debian Sid (chroot environment), and I'm running into an error. Any help would be appreciated. This is the terminal output:

That happens because you're compiling for 32-bit host (I assume either you use 32-bit Debian version or have CFLAGS=-m32 ). Even though there's nothing wrong with that, I guess we rarely target 32-bit platforms ourselves. But we'll get it fixed with use of right types where appropriate. Unfortunately adding --disable-werror to QEMU's ./configure string doesn't help in that case (see below) so the only immediate work-around for now is to target 64-bit host, is that doable for you? If not, how gating is that QEMU building for 32-bit host for you?

Thanks. I tried doing it not in any special environment, and everything worked perfectly.
