gnat via msys2 pacman + xml/ada

gnat via msys2 pacman + xml/ada

[Björn Lundin]

Hi!
Is anyone using (recently) the win-64 bit compiler found in msys2 for
windows ?


I found a post here some time ago with instructions, but:

pacman -S mingw-w64-x86_64-gcc-ada
runs fine - installs the compiler

pacman -S mingw-w64-x86_64-gprbuild-gpl
pacman -S mingw-w64-x86_64-aws
pacman -S mingw-w64-x86_64-asis

does not. They do not exist anymore.

I did find another gprbuild
mingw-w64-x86_64-gprbuild-bootstrap-git
which works ok to install.
Looking for xml/ada - I came up short.

so downloading from web I get 4.6.1
Compiling it goes well, but linking - not so much

$ mingw32-make all install
gprbuild -j0 -m -p -XLIBRARY_TYPE=static -XBUILD=Production
-XPROCESSORS=0 xmlada.gpr
gprbuild -j0 -m -p -XLIBRARY_TYPE=relocatable -XBUILD=Production

I even tried to add
  for Switches ("Ada") use ("-L" & "mingw64/bin", "-lgnat");
in share.gpr - but same result - lots of unresolved symbols.


It looks like it cannot find the gnat runtime libs.
Anyone seen this before? And have an idea of how to proceed?

Hi Björn

The most recent version of xmlada can be found at 
https://github.com/AdaCore/xmlada (same for gprbuild)


I've found these to build/work on msys2, and as you
have already mentioned/noticed, you need to bootstrap
gprbuild first, and have the xmlada sources available


The build instructions are self explanatory, and from
memory you need to specify the xmlada source directory
when building/installing gprbuild (bootstrap)

After which you need to go back and build xmlada with gprbuild

I very recently (like a month a go) tried it for the first time. It 
compiled a hello world without issue.

I also got a bunch of unresolved symbols at first but it was my fault 
because I had profiling ("-p") enabled by mistake.

I didn't try anything serious though.

Yes, I got the whole tree.
I get the same result for 4.6.1 as for 18.2 - lots of unresolved symbols.

Hmm, yes - do you have anything more detailed ?
I don't quite follow this boostrap thing.
Does gprbuild depend on xmlada?

looking in the branches/gprbuild-1.6 directory it is still xmlada
$ ./configure --help
`configure' configures XML/Ada 4.2w to adapt to many kinds of systems.

are you talking about the gprbuild in https://github.com/AdaCore/xmlada ?

> After which you need to go back and build xmlada with gprbuild

It seems that I'm on the wrong rack. No matter what I do I get
unresolved symbols.

The gprbuild from pacman is 18.0w.
The one from github is within the 18.2 tree
but the gprbuild --version shows 18.1

Neither works now to build xmlada 18.2

Did you try compiling xmlada or AWS?

etc - I've no idea how to go about fixing this Windows/mingw problem,
other than to try to sidestep it by not trying to build the shared
(relocatable) library (try configuring with --disable-shared).

You shouldn't need to rebuild gprbuild, not sure why anyone's suggesting
it.

In my past experience, there were no versions of gprbuild 
already built for 64bit msys2.  So I too tried to build it myself
with no luck.  I ended up installing a 32bit version which 
did not work at all until I called gprconfig using the --target=xxxxx
option and had it create an auto.cgpr file for me.  I then renamed it
to default.cgpr and put it in the default share location for 
gprbuild (got it from the adacore manual) and then gprbuild would work.

Nowadays I suppose you could install gnat community to get the 64bit
version of gprbuild, install the FSF gnat as well, then make sure
both are in your path but the FSF path is earlier.  This picks up
your FSF gnat (since its path is before gnat community's) but 
also gprbuild.

Does C:\tmp exist on your system ? I think on Windows you need to setup some environment variable to point to a proper tmp directory.
I haven't used Windows in years so I can't be more helpful, sorry...

Ok - I got a little bit further - I disabled shared as you suggested.
However that got me the same result.
But - I did the ./configure from a bash/mingw prompt.
It failed when make was executed in bash/mingw.
But when I started an ordinary cmd.exe prompt I get

This is with gprbuild from pacman - the 18.0 one
setting path to the 18.2 one makes it worse.


So - it looks better - but still no libraries insatlled.
I'll keep digging for a while.

I get that too: it "just" means that the documentation isn't installed,
probably because I don't have the necessary tool chain for building html
from $documentation_source_files.

You should have the static libraries and the project GPR installed
properly.

Yes, I should.
But they are to be found nowhere.
I would expect them in /ada/xml/18.2 as the prefix says - but no.
Nothing. So I created the missing _build/html and _build/latex and put
XMLAda.pdf there. But no go. I got rid of the warnings - but nothing
created. And I see that it compiles and creates the static libs. But it
does not install them.
So - I gave up (temporarily) I took all the sources and put them into a
directory and pointed _my_ .gpr file to that directory. It works - but
is a crude cludge.

I am now on to install AWS too. I think that will be easier -
if I can convince AWS that I do have XMLAda 'installed'...

I would expect the static libraries to be in
$prefix/lib/xmlada/xmlada_*.static/ and the GPRs in $prefix/lib/gnat/
(my GPRs are in $prefix/share/gpr/, don't know why the two possibilities
exist or why some GPRs end up in one or the other!)

Or I should say they get build in the source.

Yes. Strange thins are happenign here.
I now found them in

gprinstall -f -p -XLIBRARY_TYPE=static -XBUILD=Production -XPROCESSORS=0 \
        --prefix=/ada/xml/18.2 --project-subdir=lib/gnat \
        --build-var=XMLADA_BUILD --build-name=static \
        --install-name=xmlada xmlada.gpr



xmlada/18.2/static
But under a totally different root.
and it is the *.ali and lib*.a but no *.ads and no *.gpr

hmm I need to revisit this later.

I'd expect the source files to be somewhere under $prefix/include

Yes - but there are no include directories...
This - and the other strange things - made me try it on a win10 box.
I did all the above on a win2016 box.

clean install of msys2.
grabbed xmlada (gpl-2018) and it compiled ok (with --disable-shared)
grabbed aws (gpl-2018) and it did NOT compile ok

got lots of warnings and some errors
which seems bad. See below.
But I _think_ they are in the templates-parser, which we do not use.
commented out quite a bit and then
win32\build.cmd path/to/installation
worked.


copied the libs from win10 -> win2016.
Generated the system from scratch went good
started went well.
Now I'm in for some heavy testing.

Re: gnat via msys2 pacman + xml/ada

[Maxim Reznik]

I've used msys2 to build Matreshka project on Windows 64 before GNAT Community 2018 was released. At that time msys2 GNAT was most capable compiler to build it.

The only solution I found is to move gnat*.dll, gnarl*.dll into adalib/ removing corresponding gna*.dll.a libraries.

I used commands like that:

  adalib=$(dirname `gcc -print-libgcc-file-name`)/adalib
  bin_dir=$(dirname `which gcc`)
  rm -f ${adalib}/libgna{t,rl}-6.dll.a
  cp ${bin_dir}/libgna{t,rl}-6.dll ${adalib}/

After that I was able to link shared libraries.

Best regards,

Ok, thanks.
I got it to works with static linking, and that is all I need for the
moment.
But if I want dynamic linking, I'll keep this in mind
