DICE v3.16 compiler works with FS-UAE but not with vamos
I followed the instructions given in this post: https://eab.abime.net/showpost.php?p=874957&postcount=2 to install DICE v3.16 and the AmigaOS headers. With only a little effort, I got it to work for at least some simple test programs. Here are the first programs I tried:


Only ISO standard C:

Code:
#include <stdio.h>
int main(void)
{
  printf("Hello world!\n");
}
Simple AmigaOS-specific C:
Code:
#include <proto/dos.h>
int main(void)
{
  Printf("Hello World!\n");
  return RETURN_OK;
}
Both work all OK when run under FS-UAE, as long as I remember to give the -3.1 option for dcc so it knows which OS version to compile the code for.


But when I tried it under vamos, I got these errors for the first program:

It seems vamos is unable to find the header files stdio.h and proto/dos.h even though I have set the same dlib: and dinclude: assigns for vamos as for the emulated Amiga. I have verified this with "vamos dir dinclude:".


Even though vamos is unable to compile the programs, the binaries DICE produced when I compiled them under FS-UAE run all OK under vamos and print out "Hello world!" and "Hello World!" respectively on the Linux terminal.


What is going on here? Why is dcc unable to find the headers under vamos when it finds them all OK under FS-UAE?

As a fun experiment, I compiled this exact same source code:
Code:
#include <stdio.h>
int main(void)
{
  printf("Hello world!\n");
}
with both dcc on the Amiga and gcc on Linux. The result: as expected, it does the exact same thing on both systems.
The Amiga binary is 6064 bytes in size. The Linux binary is 19432 bytes, over 3.2 times as much. Yet I figure gcc has had much more development. All the program has to do is load the string "Hello world!\n" and call a system call to print it to stdout. Why, then, is the Linux binary so much bigger?

Only you can tell. What happens if you attempt to "LIST" these directories under vamos?

Say, which version of vamos do you use, and which branch? This one looks suspicious as it does not implement some of the basic exec primitives. My branch here https://github.com/thorfdbg/amitools requires an older version of python (2.7), but it is certainly good enough to drive SAS/C. I have never tried Dice C, though.

I am using vamos from Christian Vogelsang's amitools: https://github.com/cnvogelg/amitools
I tried your version of amitools earlier, but couldn't even get it to work, because it uses an older version of python. At least Christian Vogelsang's version runs on my system and is capable of running at least some of the Amiga binaries, such as most of the text-only system commands and pretty much all of the text-only Amiga programs I originally wrote on a real Amiga. It can't run GUI programs but then it's not even supposed to.


I noticed that whereas the real Amiga shell (which I ran under FS-UAE) listed each header file as executable, vamos didn't. Apparently vamos followed the underlying Linux permissions while FS-UAE just assumed every file everywhere is executable unless explicitly told otherwise. I ran "chmod u+x *.h" and "chmod u+x */*.h" on the include directory on Linux, but that didn't help, the exact same errors remained.

Based on this post: https://eab.abime.net/showpost.php?p=874957&postcount=2 I found out that I need to set up more DCC options. But running DCC from vamos is still not working. I tried this:
Code:
vamos dcc "hello.c -o hello2 -// -proto -3.1 -D__USE_SYSBASE"
Now DCC appears to be able to open stdio.h but something is still crashing vamos. Here is the current output:

Apparently the last error is coming from Python, not from vamos itself.

The Amiga binary is 6064 bytes in size. The Linux binary is 19432 bytes, over 3.2 times as much. Yet I figure gcc has had much more development. All the program has to do is load the string "Hello world!\n" and call a system call to print it to stdout. Why, then, is the Linux binary so much bigger?
Umm, actually the linux binary is ~700k (you have to compile with -static)

That version has, aparently, not implemented a couple of system calls DICE C needs. You need my version, and a pyhton 2.7.

Vamos maps the protection bits probably different than UAE does. Vamos maps the linux "u+x" bit to the "e" bit, and if these are listed as "non-executable" under linux (which they better should), their "e" bit is cleared under vamos.

The problem is, see the output, that Christian's trunk version of vamos does not implement Enqueue() and probably some other functions. Mine does.



So, you can either install a python 2.7, or port mine to python 3.0, or integrate my changes into Christian's branch, or ask Christian to do it. I am happy with either solution, but I have currently no time for it.
