How can I do to compile 32bit binary on 64bit OS systems?

Please help me......

Thanks and Regards,

Your toolchain has to be built for multilib support. Execute the following and see what you get

Code:

/lib/libc.so.6

/lib64/libc.so.6

If either one fails (I suspect the first might), then you don't have multilib support on your system.

Thanks Weibullguy!
I checked and excuted codes what you said "/lib/libc.so.6 and /lib64/libc.so.6".
I think it's no problem.

I am sorry, this time is my first time on Linux system.
I have to work to compile 32bit c and cc files on 64bit Linux OS.
Please...Help me!!
Thanks and rigards....

Do you have the glibc development files installed? The package would be named something like libc-dev or libc6-dev. There may be two, one with -i386 or something to differentiate it as the 32-bit version.

It is installed on my OS.
How do you think that this problem is OS's problem or gcc's problem?
What can I do for compile 32bit c files on 64bit OS?

Thanks and Regard....
