#56 Compilation failed with alire and gnat_native 12.2.1.

Hi Ada community,

I am learning Ada and try to build a webapp with gnoga.
I use alire and gnat_native 12.2.1 to create a new alire crate.

alr init codefirst_dockerproxy_clientweb --bin
cd codefirst_dockerproxy_clientweb
alr with gnoga
# everything works fine

and then I edit the default created src/codefirst_dockerproxy_clientweb.adb

with gnoga;

procedure Codefirst_Dockerproxy_Clientweb is
begin
   null;
end Codefirst_Dockerproxy_Clientweb;

and alr build

Here is my toolchain:

gnat_native 12.2.1        Default                                       

How can I solve this ?

Thanks

Hi Thomas,
This is a side effect of gprbuild with Alire which overloads compilation options of UXStrings with those of the main program. I haven't yet found a fix.
A possible work around consists by adding -gnatW8 in compilation options of your main program.

Hi Pascal,
Thanks, the workaround works like a charm.
