Problem running Alire under Windows: raised ADA.ASSERTIONS.ASSERTION_ERROR : Path is not absolute: C:

[rveenker]

On My PC I tried to build Alire from the github repository and am experiencing issues when running the executable.

Here is a log of what I did. Note that the currently installed Alire is alr-2.0.1-bin-x86_64-windows.zip, which works fine.

To reproduce, I built Alire from scratch (Commit: d296745691926f3c32217b59f93236281593132b):

================================================================================ D:\repos>git clone --recurse-submodules https://github.com/alire-project/alire.git Cloning into 'alire'...

D:\repos>cd alire

D:\repos\alire>alr toolchain --select Welcome to the toolchain selection assistant

In this assistant you can set up the default toolchain to be used with any crate that does not specify its own top-level dependency on a version of gnat or gprbuild.

If you choose "None", Alire will use whatever version is found in the environment.

Note: Currently configured: gnat_native=14.2.1

Please select the gnat version for use with this configuration

1. gnat_native=14.2.1
2. None
3. gnat_external=2021.0.0 [Detected at d:\GNAT\2021\bin\gnat.exe]
4. gnat_arm_elf=14.2.1
5. gnat_avr_elf=14.2.1
6. gnat_riscv64_elf=14.2.1
7. gnat_xtensa_esp32_elf=14.2.1
8. gnat_arm_elf=14.1.3
9. gnat_avr_elf=14.1.3
10. gnat_native=14.1.3 a. (See more choices...) Enter your choice index (first is default):

1 Note: Selected tool version gnat_native=14.2.1

Note: Choices for the following tool are narrowed down to releases compatible with just selected gnat_native=14.2.1

Note: Currently configured: gprbuild=22.0.1

Please select the gprbuild version for use with this configuration

1. gprbuild=22.0.1
2. None
3. gprbuild=21.0.2
4. gprbuild=21.0.1 Enter your choice index (first is default):

1 Note: Selected tool version gprbuild=22.0.1

D:\repos\alire>set ALIRE_OS=windows

D:\repos\alire>gprbuild -j0 -p -P alr_env

When I go to a crate that worked fine before, I now get an exception:

Running the 'old' Alire 2.0.1 I get:
