# Make sure it’s executable chmod +x bin/cme

# 5. Install (optional, copies binaries to /usr/local/bin) sudo make install After installation, you can start CME with:

# Create a dedicated folder mkdir -p ~/cme-8.6 && cd ~/cme-8.6

cme-full-8.6/ ├─ bin/ ← pre‑compiled executables ├─ src/ ← full source tree ├─ docs/ ← PDF/HTML manuals ├─ plugins/ ← optional add‑ons └─ README.md 5.1. Quick‑Start (Run the Pre‑Compiled Binary) If you just need a functional instance, the binary in bin/ is ready to go.

# 2. Create a build directory (out‑of‑tree build is cleaner) mkdir build && cd build

# Extract tar -xvf ../cme-full-8.6.tar You’ll see a directory layout similar to:

# Verify gpg --verify cme-full-8.6.tar.asc cme-full-8.6.tar A clean “Good signature” line tells you the file really comes from the CME maintainers. The .tar archive is a standard UNIX tape archive. Use tar (or any compatible GUI tool) to unpack it:

# Download GPG signature (optional but recommended) wget -O cme-full-8.6.tar.asc https://downloads.cmeproject.org/releases/cme-full-8.6.tar.asc sha256sum -c cme-full-8.6.sha256 # Expected output: cme-full-8.6.tar: OK If you see “FAILED”, discard the file and re‑download. 3.3. Verify the GPG signature (extra safety) # Import the maintainer’s public key (once) gpg --keyserver hkps://keys.openpgp.org --recv-keys 0xA1B2C3D4E5F67890
