在 Ubuntu 19.04 中构建 meson 时未找到手动安装的 exiv

有人能解释以下内容吗？

user@system:~/gexiv2-0.11.0/build$ exiv2 --version

exiv2 0.27.1

鉴于 exiv2 版本 0.27 不适用于 Ubuntu（它停止于v0.25）。

我做了以下事情：

  1. 我去了exiv 网站
  2. 我获取了 exiv 0.27 的 Linux 版本的链接

  3. 我运行了以下命令

    wget https://www.exiv2.org/builds/exiv2-0.27.1-Linux64.tar.gz
sudo tar xzf exiv2-0.27.1-Linux64.tar.gz -C /usr/local/lib/
sudo nano /etc/environment

  4. 添加:/usr/local/lib/exiv2-0.27.1-Linux64/bin

  5. source /etc/environment
  6. 重新启动了终端。

然后 exiv 就可以正确使用了。

但是介子在构建过程中没有检测到它的存在。

需要明确的是：软件包 gexiv2 版本0.10.9Ubuntu 19.04 的版本至少比我需要的 0.11.0 版本要差。

答案1

我发现了错误所在——您下载了 Exiv2 的二进制版本，但实际上您需要带有相应标头和开发文件的源版本。

完整的步骤如下：

exiv2 部分

sudo apt-get install cmake meson
sudo apt-get build-dep exiv2

cd ~/Downloads
wget https://www.exiv2.org/builds/exiv2-0.27.1-Source.tar.gz
tar -xf exiv2-0.27.1-Source.tar.gz
cd exiv2-0.27.1-Source/
cmake .
make
sudo make install

查看：

$ exiv2 --version | head -n1
exiv2 0.27.1

gexiv2 部分

sudo apt-get build-dep libgexiv2-dev
cd ~/Downloads
wget http://ftp.gnome.org/pub/GNOME/sources/gexiv2/0.11/gexiv2-0.11.0.tar.xz
tar -xf gexiv2-0.11.0.tar.xz
cd gexiv2-0.11.0/
meson build
cd build
sudo meson install

等等。
