Not able to compile my first C program on ubuntu after installing miracl

[mrityunjaysingh1983]

Please help in resolving my issues. I get the following error when I compile my C program.

gcc -I/home/mypc/Desktop/miracl/ ms.c
ms.c: In function ‘main’:

You need to link to the miracl library gcc -O2 first.c miracl.a -o first Mike

To install miracl in my Ubuntu system I used the following steps.

1. Downloaded .zip file by clicking Code button which is present at the website https://github.com/miracl/MIRACL.
2. Then created a directory named miracl on my desktop. Then executed the command unzip -j -aa -L miracl-master.zip on my miracl directory. Then typed Y and enter many times.
3. Then executed the command bash linux64.

My program is present at /home/mypc/Desktop and name is ms.c

My miracl.h header file is present in /home/mypc/Desktop/miracl.

When I execute gcc -O2 /home/mypc/Desktop/miracl ms.c

miracl.h no such file or directory

May I know the right command to execute on my terminal if I am executing the wrong command?

If I am doing other mistakes then please let me know.

I am facing problem in installing miracl.
I have followed the following procedure to install miracl.

1. I have downloaded the zip folder from Code button present at github. Then unzip the folder on my Desktop. It gives MIRACL-master folder.
2. Open terminal in directory MIRACL-master
3. Run gcc config.c and then ./a.out. It generates miracl.tst.
4. Renamed miracl.tst to miracl.h
5. Now, I am not able to compile miracl.lst. As I run the command gcc –I. –c –O2 mr*.c it gives the following error.
6. gcc: error: –I.: No such file or directory
   gcc: error: –c: No such file or directory
   gcc: error: –O2: No such file or directory
   gcc: error: mr*.c: No such file or directory
   gcc: fatal error: no input files
   compilation terminated.
   Please help in resolving this error.

1. Compile and run config.c on the target processor.
   Action: gcc confing.c (it gives some warning)

2. Rename the generated file mirdef.tst to mirdef.h
   Action: mv mirdef.tst mirdef.h and then copied this file in MIRACL-master/include

3. copied the standard C version mrmuldv.ccc to mrmuldv.c and use this to compile

4. Make sure that all the MIRACL header files are accessible to the compiler. Typically the flag –I. or /I. allows these headers to be accessed from the current directory.

Action: To ensure this I used the following command to compile gcc –I /home/mypc/Desktop/MIRACL-master/include –c –O2 mr*.c

5. Compile the MIRACL modules listed in the generated file miracl.lst and create a library file, typically miracl.a or miracl.lib. This might be achieved by editing miracl.lst into a suitable batch or make file. On UNIX it might be as simple as:

Action: cd /home/mypc/Desktop/MIRACL-master/source; gcc –I /home/mypc/Desktop/MIRACL-master/include –c –O2 mr*.c

It gives many error. Some are as follows. Please help me in resolving these errors.
