If alr build is run with one of the build mode flags, it will fail with the message "unknown project file: "config/*_config"" if the config gpr file does not exist:

$ alr build --release
ⓘ Building orka_numerics/orka_numerics.gpr...
orka_numerics.gpr:1:06: unknown project file: "config/orka_numerics_config"
orka_numerics.gpr:6:60: unknown package or project "Orka_Numerics_Config"
orka_numerics.gpr:31:38: unknown package or project "Orka_Numerics_Config"
orka_numerics.gpr:40:40: unknown package or project "Orka_Numerics_Config"

If I then run alr build without any flag it starts building.

I have also noticed that sometimes it doesn't update the Build_Profile variable or it does but then it doesn't update the Ada_Compiler_Switches.

$ alr build --validation
ⓘ Building orka_numerics/orka_numerics.gpr...    
Build finished successfully in 0.42 seconds.

$ alr build --release
ⓘ Building orka_numerics/orka_numerics.gpr...    
Build finished successfully in 0.42 seconds.

Right now Build_Profile is "release", but Ada_Compiler_Switches contain "-Og" instead of "-O3".

I'm using following build switches:

[build-switches]
validation.compile_checks = "warnings"
"*".style_checks = ["-gnatygAO-Is"]

(Without it I still get "-Og").

It looks like the logic to detect when to generate the config files is flaky. Thanks for the report.

Should be fixed after #1438. Please reopen if you find otherwise.
