Verifying the GCC source signature
When downloading GCC source tarballs from
ftp.gnu.org you can verify the
GPG signature with the following command line:
gpg --verify gcc-X.Y.Z.tar.bz2.sig gcc-X.Y.Z.tar.bz2
If you get the error "gpg: Can't check signature: public key not found" you first need to download the GCC GPG public key with the following command line:
gpg --keyserver hkp://pgp.mit.edu/ --recv-keys C3C45C06
