Alchitry 1.2.5 Cannot Build Default Project (Lucid or Verilog)

[BrianCechmanek]

May be related to #21 .

Using the base files for both Lucid and Verilog projects, Build Project fails:

Similar error on Debian Linux for the Alchitry Cu rst2led tutorial.

After installing the deprecated arachne-pnr tool, the example builds, uploads to the Cu, and runs correctly.

[alchitry]

The original problem was caused by the new iCEcube2 version not including the tcl script interpreter. This is fixed in 1.2.6.

The second problem is the build tools haven't been updated for the open source toolchain in a while and is unrelated to this bug as Brian is using iCEcube2. I'll open a new bug for updating the open source tools.

I am using Alchitry Labs 1.2.7, iCEcube2 2020.12.27943, on a Ubuntu 20.04 machine, trying to upload the "first FPGA project" to the Cu and I am getting

Edit (found an easy solution)

Found a fix to this, see here and/or here. Basically the problem is that all the scripts in the iCEcube2 directory start with #!/bin/sh instead of #!/bin/bash. The solution is just to replace it in each file it appears within the iCEcube2.2020.12 installation directory. You can do it by hand, however they are a lot of files, or with a recursive script that searches for the string and replaces it. I have made a Python script for this:

from pathlib import Path
import fileinput

def is_binary_file(file_path):
    # https://stackoverflow.com/a/7392391/8849755
    textchars = bytearray({7,8,9,10,12,13,27} | set(range(0x20, 0x100)) - {0x7f})
    is_binary_string = lambda bytes: bool(bytes.translate(None, textchars))
    return is_binary_string(open(file_path, 'rb').read(1024))

def replace_in_file(file_path, search_text, new_text):
    # https://stackoverflow.com/a/58217364/8849755
    with fileinput.input(file_path, inplace=True) as file:
        for line in file:
            new_line = line.replace(search_text, new_text)
            print(new_line, end='')

def recursive_walk_fixing(path):
    for p in path.iterdir():
        if p.is_dir():
            recursive_walk_fixing(p)
        else: # It is a file, we do what we want.
            if is_binary_file(p):
                continue
            try:
                replace_in_file(p, '#!/bin/sh', '#!/bin/bash')
            except UnicodeDecodeError as e:
                pass

if __name__=='__main__':
    iCEcube_path = Path(input('Path to "iCEcube2" directory? (e.g. "/home/my_name/lscc/iCEcube2.2020.12") '))
    if input(f'This script will replace "#!/bin/sh" with "#!/bin/bash" in all the scripts within the directory you provided. Write "yes" and press enter to continue, or just press enter to quit. ').lower() != 'yes':
        exit()
    recursive_walk_fixing(Path(iCEcube_path))

Thanks for the information. In Debian I recursively replaced #!/bin/sh with #!/bin/shell with this one liner:

find -type f -print0 | xargs -0 sed -i -e 's/^#!\/bin\/sh/#!\/bin\/bash/g'
