Arch Linux User Repository

@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!

gprconfig -h returns

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.

I'm probably missing something important, but... I can install gprbuild-bootstrap. If I just install gnat-gps it uninstalls gprbuild-bootstrap and fails to build xmlada with the same error. Is the same problem @flintatarta reported?

The choice for gnat-gps build is quex-for-libadalang or just quex. They both fail for libgpr>=2018 and libgpr failsfor xmlada. Seems like some kind of circular dependency.

@charlie5, OK, I will go did there for a while. Thanks

@Pjboughner,

I can't repeat the problem. It looks like gprbuild has not been installed properly.

Can't get past this

gprbuild -j0 -m -R -p -XLIBRARY_TYPE=static -XBUILD=Production -XPROCESSORS=0 xmlada.gpr -cargs -march=x86-64 -mtune=generic -O2 -pipe -fno-plt -largs -Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now No valid configuration found Generation of configuration files failed GNAT-TEMP-000001.TMP:1:01: "project" expected gprbuild: processing of configuration project "/tmp/GNAT-TEMP-000001.TMP" failed make: *** [Makefile:68: static] Error 4

What's going on with this "2018 update"? This conflicts AND provides with itself (???), and as far as pacman is concerned "18" < "2017".

I too had problems in building the package, but solved them. I am writing my experience for future help.

makepkg was stopping with "No valid configuration found." It turned out that the default knowledge base of gprconfig was not correctly installed. More precisely, gprconfig (built, I guess, with gprbuild-bootstrap) was searching the knowledge base in /share/gprbuild, but no /share directory was on my system.

In order to solve the problem I created the /share directory with

sudo mkdir /share

successively I copied the directory gprbuild in

src/gprbuild-gpl-2017-src/share/

(relative to the directory with the PKGBUILD file) in /share with

sudo cp -r src/gprbuild-gpl-2017-src/share/gprbuild /share

The commands above, of course, need to be given as root (therefore, the "sudo").

This is not building properly, and it ends up with the following error:

raised ADA.IO_EXCEPTIONS.END_ERROR : a-tigeli.adb:96
make: *** [Makefile:120: install-static-pic] Error 1
