我正在尝试在 Oracle Linux 6.4 x86_64 上将 gpg (GnuPG) 从 2.0.14 升级到 2.2 从下面的位置下载最新版本的 gnupg 和依赖库包。 https://gnupg.org/download/index.html 要安装 GPG 及其依赖项，请运行以下命令。
./configure --prefix=/usr
make
make install
"./configure" 运行时没有任何错误，但是在为依赖库 pacakges "libgcrypt-1.8.6","libassuan-2.5.3" 和 "libksba-1.4.0" 执行 "make" 和 "make install" 时遇到错误”。注意：安装依赖库包“npth-1.6”和“libgpg-error-1.38”没有任何错误。
下面是遇到的错误。
libtool: link: (cd ".libs" && rm -f "libgcrypt.so.20" && ln -s "libgcrypt.so.20.2.6" "libgcrypt.so.20")
libtool: link: (cd ".libs" && rm -f "libgcrypt.so" && ln -s "libgcrypt.so.20.2.6" "libgcrypt.so")

其他库安装也遇到类似错误。
OracleLinux6.4 是否支持 GPG2.2？我可以在 RHEL7 上从 GPG2.0 升级到 2.2
