Newbie Pure C

[FreekBos]

Hi guys.

I am trying to write my first c application on the Atari 520ST+
I decided to use Pure C and ofter several hours of copying and trying to get the harddisk to function again I am finaly ready to start programming.

When I compile a suuuuper simple c application I keep getting Bus Error - Program Aborted.

My Test.prj file looks like this:

Code: Select all

test.prg
=
test.c


My Test.C file looks like this:

Code: Select all

int main()
{
   return 0;
}


What am I doing wrong? Am I missing some setting in Pure C or something?

Happened to me after some PureC off-time, too.
You forgot the startup code

Code: Select all

test.prg
=
pcstart.o
test.c


It has to be the first item after the equation sign "="!

Thanks for the swift reply!
Now I get stuck with the Linker when compiling the code.
It says
C:\Tools\Code\Pure_C\Lib\PCStart:
Undefined symbol: '_fpuinit'
Undefined symbol: 'main'
Undefined symbol: '_freeAll'

Do I have a Linker or Compiler setting wrong?

And... when I swithc on the Linker option -J (Create new object file)
It tries to run... but it gives me the error 'Load format error'.

Is the path to the libs set correctly?
Anyway: you need to add the appropriate libs to the project file, too.
Why don't you check "default.prj"?

You don't need linker option, you need add the standard C-library.

Project file for (Pure-C compatible) AHCC Hello Word looks like this:

Code: Select all

hello.tos
=
ahcstart.o
hello.c
ahccstd.lib


(For PC, the start object and library names are different from AHCC, headers are compatible.)

[FreekBos]

Thanks Eero, that did the job.
For Pure C I had to change the PRJ file to:

test.tos
=
pcstart.o
test.c
pcstdlib.lib

Good to see you're up and running! Once you get more comfortable with C you should check out dml's AGT: https://bitbucket.org/d_m_l/agtools
