Commenting out ansipipe leads to an error.

[mobluse]

Hi,
I tested this in Ubuntu in WSL (AKA BashOnWindows) on Windows 10 and it worked well! Now I wanted to test it on my web hotel https://www.one.com/ via ssh, but then git clone --recursive didn't work completely, see error below. The problems are with ansipipe. Since this web hotel doesn't have gcc I doubt that ansipipe could work even if I could download it because it seems to be a C program in source form. I saw you mentioned in #1 that ansipipe was not necessary and could be commented out. I did this in the file ./pcbasic/main.py , but that led to an error. I could type system to quit BASIC.

  Ok?

It's probably best to try and get the full clone to work - from the log it looks like there was a github connection problem and quite probably more than just ansipipe could be missing.
You won't need the C source or a GCC compiler on Linux, but it does import a python module that's in the ansipipe directory.

I'm not sure where the error you see comes from, but it doesn't look ansipipe-related. On my own Ubuntu machine, I don't see this error when I comment out ansipipe.

If the clone doesn't work, you can install on Ubuntu from one of the .tgz releases, either the stable version 15.08.1
https://github.com/robhagemans/pcbasic/releases/download/15.08.11/pcbasic-15.08.11.tgz

or the development version 16.12.0rc0
https://github.com/robhagemans/pcbasic/releases/download/16.12.0rc0/pcbasic-16.12.0rc0.tgz

If it still crashes with the full install, could you attach the crash log?

I tried https://github.com/robhagemans/pcbasic/releases/download/16.12.0rc0/pcbasic-16.12.0rc0.tgz , but I get the same error.
pcbasic-crash-20171014-Fk10TX.log
When I install to pcbasic it says:

Checking dependencies ...
checking Python module xdg ... installed
checking Python module pygame ... NOT INSTALLED
checking Python module numpy ... NOT INSTALLED
checking Python module serial ... NOT INSTALLED
checking Python module parallel ... NOT INSTALLED
checking Python module pexpect ... installed

WARNING: The following Python modules were not found:  pygame numpy serial parallel
Please install them separately to ensure all PC-BASIC functionality works correctly.

INSTALLATION COMPLETED. 

I have successfully installed xdg, serial, and parallel, but it still says serial and parallel are uninstalled. I installed e.g. using
python -m pip -v install parallel --user
I had to use --user otherwise it would not install. I don't have sudo on this account.

I could not install numpy because the process was killed for some unknown reason.

The reason why clone of git://github.com/robhagemans/ansipipe.git doesn't work might be that some port is blocked. If it used https instead of git it would probably work.

I just realised this is the same error as #45, which is linked to #24. In short: for the dev version, you need Python 2.7.12 or higher, and older Ubuntu doesn't have this. The stable version should work, though.

Since this issue is covered by #24 I'm going to close it, but feel free to re-open if you see further issues.

NB - You can run without serial and parallel but numpy is required for the dev version. The stable version can run without it, though some functionality will be disabled. Without pygame you only have a text interface (on the command line).

I think pip installs to a separate location from the regular Ubuntu packages which is why they may not be seen by PC-BASIC. So you'd have to get your administrator to install numpy at least, I think, or work from a correctly cloned git.

If your firewall causes problems, the submodule address is set in .git/config so you can change it there and update the submodule - see the git documentation for more on that.
