AMD AOMP compilers (new flang)

rwmsu · January 25, 2026, 2:59am

Has anyone tried the AMDs AOMP compilers based on new LLVM flang (not classic flang like their AOCC compilers). Just wondering if its worth spending the time trying to get them installed on my Linux boxes. I’ve tried to install the precompiled LLVM flang versions on the LLVM site but can’t get them to work. Best I can figure out its looking for a particular version of (g)libc. The error message just says it can’t find libc. Maybe its a path problem though.

For those who are interested in trying, below is a script for installing the new flang provided by AMD AOMP (aka amdflang) on GitHub Actions, of course, before setup-fortran supports it (@wpbonelli).

github.com/equipez/github_actions_scripts

install_aomp

main

#!/usr/bin/env bash
# Script to download the latest AOMP release for Ubuntu (amd64/x86_64)
# Usage: bash install_aomp

set -euo pipefail

# Allow update to fail (|| true) but proceed to install
sudo apt update || true
sudo apt install -y curl jq libelf-dev libzstd-dev  # jq needed for GitHub API parsing

# Make a temp directory and move into it
TEMP_DIR="$(mktemp -d)"
cleanup() {
    # Only remove if it still exists
    [[ -n "${TEMP_DIR:-}" && -d "${TEMP_DIR}" ]] && rm -rf -- "${TEMP_DIR}"
    TEMP_DIR=""  # Prevent double cleanup
}

trap cleanup EXIT

N.B.:

The script installs the compiler only. It does not install the HIP libraries. If you need them, you may modify the script yourself.
If you would like to use it on your local machine (Ubuntu), remove the following two lines:

# Set environment variable for subsequent steps
echo "PATH=$PATH:$AOMP_DIR/bin" >> "$GITHUB_ENV"

Also, a new version of the AMD AOCC compilers (V5.1) was released on Jan 2.

The following script installs it for GitHub Actions.

github.com/equipez/github_actions_scripts

install_aocc

main

#!/usr/bin/env bash
# Usage: bash install_aocc
#
sudo apt update && sudo apt install 7zip-standalone libncurses* -y  # libncurses* needed for libtinfo.so

REPO_NAME=aocc_flang
TMP_DIR="$(mktemp -d)"
cd "$TMP_DIR" || exit 42
git clone https://github.com/zaikunzhang/"$REPO_NAME".git

cd "$REPO_NAME" || exit 42
AOCC_7Z="aocc_flang.deb.7z.001"
7za x "$AOCC_7Z" -aoa  # -aoa: overwrite all existing files without prompt

# Install the package (apt resolves dependencies; dpkg alone does not)
sudo apt install -y "$TMP_DIR"/"$REPO_NAME"/aocc_flang.deb
cd ~ && rm -rf "$TMP_DIR" || exit 42

# Run the script that sets the necessary environment variables and then damp them to $GITHUB_ENV
# so that they are available in subsequent steps.

For those who are interested in the ARM Fortran Compiler, which is also based on the LLVM Flang:

github.com/equipez/github_actions_scripts

install_atfl

main

#!/usr/bin/env bash
# Install Arm Toolchain for Linux (atfl)
# Usage: ./install_atfl

set -euo pipefail

# Update package lists and install prerequisites
sudo apt update || true  # Ignore errors from apt update
sudo apt install -y curl gpg environment-modules

# Add Arm repository and install arm-toolchain-for-linux
VERSION_YEAR=$(lsb_release -rs | cut -d. -f1)  # e.g., "24" for Ubuntu 24.04
VERSION_CODE=$(lsb_release -cs)  # e.g., "noble" for Ubuntu 24.04
curl "https://developer.arm.com/packages/arm-toolchains:ubuntu-${VERSION_YEAR}/${VERSION_CODE}/Release.key" \
    | sudo gpg --dearmor -o /usr/share/keyrings/obs-oss-arm-com.gpg
echo "deb [signed-by=/usr/share/keyrings/obs-oss-arm-com.gpg] https://developer.arm.com/packages/arm-toolchains:ubuntu-${VERSION_YEAR}/${VERSION_CODE}/ ./" \
    | sudo tee /etc/apt/sources.list.d/obs-oss-arm-com.list

# Update package lists and install the toolchain
sudo apt update
