I can confirm that i get the same error for gprbuild-bootstrap 2020-2

Sorry, can't reproduce in a clean chroot with gcc-ada-10.1.0-2 and gprbuild-bootstrap-2020-2. It's always possible that AdaCore -git packages are incompatible with the latest release versions of other packages, but if the same happens with gprbuild-bootstrap, I have no idea.

@xiretza gcc-ada 10.1.0-2 gprbuild-bootstrap-git r3595.e7f7c8d5-1

I tried both available options for gprbuild-bootstrap and currently have the git version installed

@NJ4BIEXXQk: pacman -Q gcc-ada gprbuild-bootstrap

Hi, I get

gprconfig -h returns

-db-    : Do not load the standard knowledge base from:
   /usr/share/gprconfig

Is this related to the previous problems? I would really appreciate any help

I've made a start on the 2019 packages. They should be ready by the end of the weekend.

gcc-ada 9.1.0 is out. Could you please update the dependencies?

@Pjboughner,

As you suggest, "Do not load the standard knowledge base from: /share/gprconfig" appears to be the problem. 'gprbuild' is looking in the wrong place for its config.

Atm, I'm not sure why it is looking in '/share', rather than '/usr/share' (as on my box), for 'gprconfig'.

As a temporary workaround, you might try

$ sudo ln -s /usr/share /share

Btw, the next release of the libre GPL packages should be within a few weeks, so the workaround should only be temporary.

thanks again!

there is a usr/share/gprconfig folder (with files) gprbuild-bootstrap installs xmlada won't build

I think I got -git's to build once, but gnat-gps replaced them all

Reading through grpconfig -h it does appear that the knowledge db it's looking for is in the wrong place (or it's looking in the wrong place for Arch maybe)

@Pjboughner,

It appears to be a similar problem to flintatarta's. Can you show the output of

$ gprconfig -h

Also, is there a /usr/share/gprconfig folder on your sytem ?

GPS (or libadalang, rather) requires a specific version of 'quex', hence the need for quex-for-libadalang.

There is a circular dependency. 'gprbuild' depends on 'libgpr', which depends on 'xmlada', which depends on 'gprbuild'. The circularity is broken by introducing 'gprbuild-bootstrap'.

The normal build order should be: gprbuild-bootstrap xmlada libgpr gprbuild (which should replace gprbuild-bootstrap)

Hope this helps.
