hi. I need to get a opengl graphics file to excute in linux have used the make method and think this worked but not sure of how to execute. Not a fan of linux but need to do my method looks something like this ./COMP307/src./eg1
??????????

Here's the thing: With computers these days (at least with Linux), "something like this" doesn't feed the bulldog.

Tell us:

1. What is the name of the executable (the program that was created when you "used the make method")?

2. Where are you (what directory are you in) when you want to execute the program? Exactly.

3. Where (exactly) is the executable program?

4. Were there any installation instructions? Was there a README file or an INSTALL file in whatever directory you were in when you "used the make method"? Or: were there any installation instructions that you got from wherever you got the files that you used to create the executable? Did you do anything other than enter "make"? That is, was there any configuration script or other program that you executed?

No one can guarantee to be able to help you by remote control, but I'd like to try. The chances are probably directly proportional to the amount of information (and the amount of specific information) that you give us.

One final suggestion: you might mention what Linux distribution you are using. It probably doesn't matter (much), but sometimes it makes a difference to people trying to help.

Hi

I used the method make ./COMP307/src/eg1.c

Am using my university home drive the work is in a folder called Comp 307

I copied a directory ~comp307 etc into my file space successfully so the correct files are I my folder

And I’m trying to compile on unix (exceed) think the make method worked it just says nothing to be done

thanks

The program that is executed when you enter "make xxxx" looks into a file (either "makefile" or "Makefile") for targets. In particular it looks to see whether there some reference to something named "xxxx". Normally the target would be an executable (maybe eg1, but I have no way of knowing). The target will have a list of files that it depends on. Probably eg1.c would be one of those files.

If you enter "make eg1.c", since eg1.c is not a target, then there is nothing for "make" to do (since , presumably eg1.c is already there and it doesn't have any dependencies.). On the other hand if eg1 is a target and you enter "make eg1" the program will apply rules from the Makefile to create eg1.

Typically this would be: If any of its dependencies, such as eg1.c, has a later timestamp than the target, or if the target file doesn't exist, then the compiler and linker are called in such a way as to create a new target.

The "make" program is extremely powerful, and it's not the easiest thing in the world to figure out all of its uses, but if you are given a Makefile and you have all of the dependencies present, then using it is easy.

So you have to get instructions from wherever you got the files. If there are no instructions (no README or readme.txt or anything else in the directory or in your homework assignment), then you have to Ask Someone at your site (instructor, lab assistant, other student who has already done it, ...)

What are you supposed to "make"?


A final note:I almost forget to mention that if everything is set up correctly and the desired target is the first (or only) target, then you can just enter "make" without any argument and it will do its thing. (It may not work, but it might be worth a shot.)

Regards,

Dave
