Compile program for 32bit on 64bit Linux OS causes fatal error


gcc -m32 myprog.c

should compile in 32 bit version the file

unfortunately I get this error

In file included from /usr/include/stdio.h:27:0,
from myprog.c:1:
/usr/include/features.h:374:25: fatal error: sys/cdefs.h: No such file or directory
# include <sys/cdefs.h>

How could I fix this?

If I don't use
works but uses 64 bit istructions


To compile 32 bit binaries on 64 bit Linux version, you have to Install libx32gcc development package and 32 bit GNU C Library

try this

sudo apt-get install libx32gcc-4.8-dev


sudo apt-get install libc6-dev-i386
