Compile C programs in Puppy Linux 2.13

[Lobster]

You will need the latest 60 MB compile file eg devx_213.sfs
Download from here:

http://www.puppyos.net/test/

and place in mnt/home (this is where pup_save.2fs is)
Reboot computer

Save the following as test.c
If using Geany, set it it to C and test compile first

Code: Select all

/*  Example C program */

int main()
char input_character;

  { int i;
	   for (i = 0; i < 50000; i++)
	     {
	       printf ("%d",i);
	       printf (" Puppy is Great\n");     
	     }
	   return 0;
   }

in the same directory
open a terminal (Right click in the open folder/directory with Rox 2.5 /Window/terminal here)
and type

Code: Select all

gcc test.c -o test

this will create a runnable file called "test"
the command

Code: Select all

./test

will run it . . .

find a good tutorial eg.

to show any possible errors, (as sometimes a program can compile even though it may have problems), compile with:

Code: Select all

gcc test.c -o -Wall test

Hi all,
My problem,
downloaded devx_213.sfs ok.
not sure where mnt/home is so I put it in /mnt where I found some pupsave 2fs files. Rebooted and copyed the test program into new file saved as test.c
tested in geany - Compilation failed.
moved test.c file into /root/mnt just in case it can't find complier

tried setting Geany, to C - not sure if I did that is correctly
Geany error message -
C -Wall -c "test.c" (in directory: /root/mnt)
Compilation failed.
/bin/sh: C: command not found

also tried from command line in case of geany problems
same error message - command not found

devx_213.sfs should be located in /mnt/home, if you're using the cdrom, or a co-exist,
(or frugal), hard disk install.

if you type gcc -v , & bash says command not found , then possibly devx_213.sfs is in the wrong place, it's an incompleted/corrupt download, or maybe you've got a full(normal) hard disk install.

also, i've never used C to compile c programs. i just tested it on a simple program & it complained that -Wall was an unknown option, and a few other errors. (What actually is C a frontend for?)

anyway, compiling the same program with gcc -Wall test.c -o test worked fine.

My puppy is loaded as a full harddrive install.
So, where does one put the file "devx_213.sfs"
do you need to set path statements anywhere?
do you need to tell the system to load "devx_213.sfs" ?

with a full puppy install of versions 1.xx, the developer .sfs module is just copied to / and puppy will find it. however with the pup2.xx series, you need to manually mount the devx_2xx.sfs then recursively copy the files to / .

if you check this link, see 2/3's down the page, where barry mentions c/c++ compiling:

BK mentions two links there, I found that this is the link you need: http://www.murga.org/~puppy/viewtopic.php?t=8871
follow exactly the instructions in the second post (by "tony") and it should all burst into life

www.beej.us he has an excellent beginner's guide to programming C, it says alpha because theres missing images and he doesnt know order of operations.

Order of Operations:
Parentheses
Exponents
Multiplication and Division
Addition and Subtraction

Yay me!
