"Has_Compatible_Representation" is undefined #15

Closed matthewbdwyer closed 4 years ago

matthewbdwyer commented 4 years ago

Trying to build gnat-llvm on Ubuntu 20.04 using gcc (GCC) 9.3.1 20200430 (for GNAT Community 2020 20200429).
Using clang/llvm resulting from "apt install llvm-dev" which resulted in:

mbd$ llvm-config --version 10.0.0 mbd$ clang --version clang version 10.0.0-4ubuntu1 Target: x86_64-pc-linux-gnu Thread model: posix InstalledDir: /usr/bin

Followed the instructions and the build ended with the following:

gnatllvm-aliasing.adb:303:18: "Has_Compatible_Representation" is undefined (more references follow)

compilation of gnatllvm-aliasing.adb failed

gprbuild: *** compilation phase failed

FWIW: I built gnat-llvm successfully on Ubuntu 18.04 back in early May.

Indeed, the corresponding change in GNAT will be there shortly. In the meantime, you can get back to commit 20ba5ac3e29ec4b5cd3fb4e70f0c67f7f63336bb to get a working build.
