guix build: error: gcry_md_hash_buffer: Function not implemented

[jgart]

Look what I saw today:

guix build: error: gcry_md_hash_buffer: Function not implemented

WDYT

I was trying to do the following:

make -j5 && ./pre-inst-env guix build nnn

TMI?

help2man: can't get `--help' info from guix home
Try `--no-discard-stderr' if option outputs to stderr
make[2]: [Makefile:7023: doc/guix-home.1] Error 1 (ignored)

I also run into this error, when I checkout the latest master 
branch of the Guix repository (commit 
fccb48d2cec6bcf47647c82914f31e2dff617f9c) and then run:

  guix shell -D guix
  ./bootstrap
  ./configure
  make

Sorry. I meant "./configure --localstatedir=/var 
--sysconfdir=/etc".

Hi, thanks.

Is the --sysconfdir necessary? 

I've never used that. What does it mean or where should I get the TLDR/RTFM(L) on it?

It's strongly encouraged. It means you'll use /etc/guix instead of
/usr/local/etc/guix when it comes to checking for substitute keys and
whatnot.

The only thing I know is that this command is instructed in info 
node "(guix) Building from Git", i.e. in Guix' manual's chapter 
"22.1 Building from Git". Unfortunately, in the manual as a whole, 
there is no documentation that explains what this argument does.

I just pushed a small doc commit,

"26a788ae06 doc: Add some information/recommendation regarding
--sysconfdir."

that I hope rectifies this!

Let me know if something can be improved still.

I think the “make install” part means here “./pre-inst-env guix pull”.
Well, that’s the only case where I had troubles because this value is
recorded and can be propagated.  Consider,

    ./bootstrap && ./configure --localstatedir=/var && make
    ./pre-inst-env guix pull
    guix pull --commit=1234abc

and compared to the sequence without ./pre-inst-env:

    guix pull
    guix pull -- commit=1234abc

then it does not lead to the exact same Guix.  For examples:

        https://yhetil.org/guix/8635nkshpy.fsf@gmail.com
        https://yhetil.org/guix/86eehycjre.fsf@gmail.com

Cheers,

'sudo -E ./pre-inst-env guix system reconfigure ...' would be another
such incantation that requires --sysconfdir to be set to /etc.  Since we
now recommend it to always be used, it is covered should these
"advanced" commands be used, I think.

Hi Maxim,

I just read 26a788ae06.

That reads great! 

Thank you for improving the documentation on that. It is much appreciated.

all best,

Hi,

Can this be closed now given the recent mention of --sysconfdir?

Mekeor,

That's why I was asking because I never saw it explained in the Guix manual.

Maybe it is some GNU tribal knowledge that we are expected to eventually learn? dunno.

But, Efraim just gave a nice TLDR.

I'll try to find sometime to rework what he said into the docs unless someone else gets to it first ;()

all best,

jgart
