每当我尝试在运行arch linux的机器上交叉编译我的rust项目时，使用x86_64-unknown-linux-gnu架构的cross，我得到这个错误
$ cross build --target x86_64-unknown-linux-gnu

我有gpgme = "0.11.0"作为我的Cargo.toml文件的依赖
- 我重新安装了
libgpg-error包 - 尝试将
pkg-config --path gpg-error的输出添加到PKG_CONFIG_PATH变量中。pkg-config --path gpg-error的输出为/usr/lib/pkgconfig/gpg-error.pc
这个适合我:
sudo apt-get -y update &&安装libgpgme-dev安装libgpg-error-dev
然后重启终端。
