ld: library not found for -lz.1.2.3

你能帮我理解一下吗？

非常感谢;）

Answer 1

选项-lz.1.2.3表示编译器正在尝试链接文件libz.1.2.3.a，libz.1.2.3.so或libz.1.2.3.dylib。它无法找到任何这些变化，并因此而失败。

您可以尝试查找此文件的位置，并将其包含在库包含路径中。

我的问题是为什么要链接特定版本的z lib？通常，只要有-lz或-llibz.dylib就足够了。您有理由选择特定版本吗？使用未版本名称链接时会发生什么。

Answer 2

只需使用-lz，就不需要使用版本化链接。所以从框架中删除libz-1.2.3.tbd并添加libz.tbd。

1. 在项目导航器中，选择您的项目。
2. 选择目标。
3. 选择＆＃34;构建阶段＆＃34;标签。
4. 打开＆＃34;链接二进制文件与库＆＃34;膨胀器。
5. 删除libz-1.2.3.tbd
6. 点击+按钮。
7. 添加libz.tbd
