Problems with using vamos as a shell #148
Comments

thanks for the bug report. can you share the compiled dice program so I can have a look? |
|
hello.zip |
|
Found this issue as well: console device '*' was not handled correctly... please test current master |
|
I have earlier been downloading ZIP packages from the amitools repository. For convenience I cloned the repository directly with git so I can get updates faster. I tried to run "assign", which should list all the assigns in the system, but once again, vamos crashed. Here is the output: The last line looks like it's trying to print out the assigns (typing "assign" without any parameters to a real AmigaOS shell lists all the assigns, starting with the volumes) but it fails to actually print them out. |
|
Assign output should now be fixed on master |
|
Assign works fine. |
|
vamos is unable to run shell scripts. |
I bought AmigaOS 3.1.4 from Hyperion Entertainment and installed the latest version of amitools. Typing "vamos -x Shell-Seg" where Shell-Seg is the file I got from AmigaOS 3.1.4 dropped me to an emulated AmigaOS shell. Only, not everything is working correctly.
Running "dir", "list", or "type textfile.txt" where textfile.txt is a file in the current directory is working perfectly. However, "echo foo" crashes vamos with the following error:

Also, I compiled this simple program:
#include <stdio.h>
int main(void)
{
printf("Hello world!\n");
}
with dcc on the DICE compiler. Typing "hello" on the vamos shell printed out "Hello world!" as expected, but the shell just stuck there, not accepting any further input. I had to press ctrl-C to tell Linux to break the entire vamos process.
The same happens when I type "endcli" in the shell. The shell says "Process 0 exiting" but after that, vamos just sticks there.
The text was updated successfully, but these errors were encountered:
