Building adalang tools

[MrAda]

I am trying to find a way to build gnatpp and after trying to use the make command, which didn't work, I tried to use alire. I have so many files that not compiling it isn't funny. Why is it that someone just doesn't build the adalang-tools so we can just pacman them?

I had the same issue, so I did this:

I'll try this and thanks. You need to mention before the instructions that one has to be in a crate. So I did this:
alr init --bin test
cd test
then you alr build --release
This got me started.

So doing the sh command within Alire is not working. Not recognizing sh command. This is on windows....

[MrAda]

I decided to do the install in msys and this is what I got:
$ sh install.sh "C:\GNATSTUDIO\bin"
find: ‘./alire/cache/dependencies/libadalang_tools*/bin/’: No such file or directory
Done!
There is nothing in the cache folders.

[MrAda]

I even tried:
$ ./install.sh "C:\GNATSTUDIO\bin"
and it didn't produce anything.

[dinkelk]

I'll update the instructions, thank you for the feedback. You should clone the repository and then run alr build --release from within the repository root. I admit that I have not tested this on windows.

If there is nothing in the cache folders, I would expect that the alr build command failed. Did it seem to build correctly? It takes ~30 minutes on my machine.

[MrAda]

Ok. Retried again and this :
PS C:\Users\Chris\test\libadalang_tool_builder-main> alr build --release

So libgmp* and libiconv* are in my MSYS package list:

$ pacman -Q | grep gmp
gmp 6.3.0-1
gmp-devel 6.3.0-1
mingw-w64-clang-x86_64-gmp 6.3.0-2
mingw-w64-ucrt-x86_64-gmp 6.3.0-2

$ pacman -Q | grep iconv
libiconv 1.17-1
mingw-w64-ucrt-x86_64-libiconv 1.17-3
mingw-w64-x86_64-libiconv 1.17-3

So I am not getting why it cannot find a complete solution!
This Alire stuff is a real P.I.T.A.

Yes, the issue must be with one of those system libraries that differ by operating system. For what it is worth, this is what it looks like when I run on Linux:

user@e6613a10f946:~/libadalang_tool_builder$ alr build --release

ⓘ Deploying libgmp=6.2.1...

This action might require admin privileges and impact your system installation.
Do you want Alire to install this system package?
[Y] Yes  [N] No  [A] Always  (default is Yes) Yes

And then libgmp-dev seems get installed as expected, and then the Ada source starts getting compiled. Maybe Alire is just not seeing those the gmp or iconv libraries for some reason, even though they are installed.

Hopefully an expert can chime in. I am sorry that didn't work for you out of the box.

[MrAda]

Thanks. I will try to do this on linux in a VM. We'll see if that is momentous or not! :-)

[MrAda]

I tried to build alire from scratch and that worked nicely. When I went to try and build libadalang_tools I got this:
PS C:\Users\Chris> alr get libadalang_tools

Seems there is some issue with finding libiconv and libgmp from Windows. I am still waiting for my VM to build to try it on linux

[MrAda]

Thanks. I will try to do this on linux in a VM. We'll see if that is momentous or not! :-)

So I did try linux, specifically CentOS 7.9. Alr seemed more natural in this environment, but I still had issue with libgmp which did exist on my system. I wish ACT still did the community releases or at least document so I can reproduce an Executable like they did. This piece-mealing of all of the parts is time consuming and frustrating when things dont work out of the box.

[MrAda]

Arg! Had to install gmp-devel and it found the missing gmp.h file! I am building now. I see a lot of warnings which is not very "Ada-like".

[MrAda]

Ok. Under CentOS, I was able to build or so it seemed your crate. I don't see any executable except libadalang_too_build which does nothing AFAIK. So I ran the "sh install.sh ..." and got an error find: '.alire/cache/dependencies/labadalang_tool*/bin/' : No such file or directory

Did it create gnatpp or not?

[MrAda]

I found the executables! In some obtuse folder:
/home//.local/share/alire/builds/libadalang_tools_23.0.0_............./bin
wtf is that about? I am wondering if this nonsense is also on the windows side. I have a righteous headache now from all of this.

[MrAda]

ok. I got the install.sh to work. The line:
dir="./alire/cache/dependencies/$1*/bin/" doesn't work because the folder doesn't exist.
I changed it to
dir="/.local/share/alire/builds/$1*/bin/"

That worked and installed the executables!

[dinkelk]

Awesome! Glad you got it going. It would be nice if Alire had a way to just download, build, and install tools outside of a crate. I agree, this whole thing is a bit awkward - and I miss being able to just download GNAT Community and get all the goodies. Hopefully these are just transition period growing pains...
