Package: libc6-dev-x32
Version: 2.24-11+deb9u1
Severity: important
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
I was trying to compile a program for the x32 ABI.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Create a program test-errno.c:
#include <stdio.h>
#include <errno.h>
int main(void)
{
printf("Hello World: %d\n", errno);
return 0;
}
Compile it with "gcc-6 -mx32 test-errno.c"
* What was the outcome of this action?
I get this error:
In file included from /usr/include/bits/errno.h:24:0,
from /usr/include/errno.h:35,
from test-errno.c:2:
/usr/include/linux/errno.h:1:23: fatal error: asm/errno.h: Adresář nebo soubor
neexistuje
#include <asm/errno.h>
^
compilation terminated.
* What outcome did you expect instead?
The package libc6-dev-x32 should contain all the include files needed to build
programs for the x32 ABI.
The package seems to be missing the directory /usr/include/x86_64-linux-gnux32.
When I create this directory and copy include files to it, the compilation
succeeds.

The problem is that you also need to install support for the x32 ABI on
the gcc side. You should install gcc-multilib for that, it would provide
the /usr/include/linux/asm symlink.
