Hi All,
I am trying to include a mcrypt.h header but I am getting the below error:
test01> gcc test1.c
test1.c:5:20: fatal error: mcrypt.h: No such file or directory
#include <mcrypt.h>
^
compilation terminated.
As I cannot put my encryption program here, so have put a sample code which I ran :
/* Hello World program */
#include<stdio.h>
#include <mcrypt.h>
main()
{
printf("Hello World");
}
libmcrypt is installed as below in UNIX
lrwxrwxrwx 1 root system 43 14 Jul 16:29 libmcrypt.so.4.4.8 -> ../../opt/freeware/lib64/libmcrypt.so.4.4.8
lrwxrwxrwx 1 root system 39 14 Jul 16:29 libmcrypt.so.4 -> ../../opt/freeware/lib64/libmcrypt.so.4
lrwxrwxrwx 1 root system 37 14 Jul 16:29 libmcrypt.so -> ../../opt/freeware/lib64/libmcrypt.so
lrwxrwxrwx 1 root system 34 14 Jul 16:29 libmcrypt -> ../../opt/freeware/lib64/libmcrypt
Thanks in ADVANCE.

You will have to install the package libmcrypt-dev as it provides mcrypt.h .

Hi Zaxxon,
Thank you for your reply.
But as I have mentioned, libmcrypt is already installed :
lrwxrwxrwx 1 root system 43 14 Jul 16:29 libmcrypt.so.4.4.8 -> ../../opt/freeware/lib64/libmcrypt.so.4.4.8
lrwxrwxrwx 1 root system 39 14 Jul 16:29 libmcrypt.so.4 -> ../../opt/freeware/lib64/libmcrypt.so.4
lrwxrwxrwx 1 root system 37 14 Jul 16:29 libmcrypt.so -> ../../opt/freeware/lib64/libmcrypt.so
lrwxrwxrwx 1 root system 34 14 Jul 16:29 libmcrypt -> ../../opt/freeware/lib64/libmcrypt
Let me know if I am wrong, as I am new bee in C programming.
Thanks.
*shrug* All right, you're wrong.
Most binary distributions split packages into two parts, those needed to compile with them, and those needed to just use them. I consider this a bad habit inherited from the 90's when hard drive space was at a premium, not really necessary now in most situations.

You need to install libmcrypt-dev, too.
