Bootstraping Factor Triggers a bug.

[Gamer2014]

On Ubuntu 18.04.4 LTS (Bionic Beaver), While following the steps for building from a clean branch of Factor at "https://concatenative.org/wiki/view/Factor/Building%20Factor"

I received the error message after executing this step: ./factor -i=boot.unix-x86.64.image

You have triggered a bug in Factor. Please report.
critical_error: The die word was called by the library.: 0
Starting low level debugger...
Basic commands:
q ^D -- quit Factor
c -- continue executing Factor - NOT SAFE
t -- throw exception in Factor - NOT SAFE
.s .r .c -- print data, retain, call stacks
help -- full help, including advanced commands

What steps can I take to get around this error/bug?

[mrjbq7]

Do you have a boot image?

[mrjbq7]

I recommend trying the basic steps to build from source:

https://github.com/factor/factor#building-factor-from-source

[Gamer2014]

Yes, I downloaded boot.unix-x86.64.image from https://downloads.factorcode.org/images/master/

I will try the basic build as you suggested & let you know the results. Thank you.

[mrjbq7]

It's odd that it wouldn't work. Did the build produce any output before the error message?

[Gamer2014]

Here is the output from my console:

Weird that it can’t detect WORD size and reports “126”?

What does ``uname -s`` return? Are you using msys2? mingw? Please link me to an installer and I can try it. It looks like the C test program is returning 126 when you run it, which means you don't have permissions. I can add a check that it returns only 32/64 so we error earlier. If you compile this program you can also try to debug it: # foo.c: int main() { return (long)(8 * sizeof(void*));} # gcc or whatever for cc here cc -o foo foo.c ./foo echo $?

Based on what Doug Coleman wrote I changed the permissions on the build.sh file to:

[mrjbq7]

There seem to be a couple of problems. This is causing the build update to fail: Finding WORD... ./build.sh: line 325: ./factor-word-size: cannot execute binary file: Exec format error But maybe the underlying cause of that is causing the subsequent die when bootstrapping an image. Question; Does a binary download work on your computer?

Looks like a binary will work. here's a screenshot.

[erg]

The permissions are failing on the script that determines the word size, 32 or 64, not on build.sh. Don't change the permissions on build.sh build.sh generates a C file that compiles (CC returns 0) but then fails to execute because of permissions. I tried to give some instructions to make this C program in my previous email so you can debug the permissions on that generated file. What is the output of umask? $ umask 0022 What is the output of ``uname -s``? $ uname -s MINGW32_NT-10.0-18363 Compile and run this and fix the permissions if necessary: // foo.c int main() { return (long)(8 * sizeof(void*));} gcc -o foo foo.c ./foo # expect permissions error # chmod a+x foo # expect it to work, then ``echo $?`` for 32 or 64
