Undefined reference to 'inflateInit2_'
提问by Jake
I'm using Code Blocks IDE and I want to install Tiled Map Editor for SFML. So, I downloaded the source and imported it to my project. Unfortunately, the build finished with an error due to missing zlib library. I downloaded it and built again. This time I received an error that reads:
我正在使用代码块 IDE，我想为 SFML 安装 Tiled Map Editor。所以，我下载了源代码并将其导入到我的项目中。不幸的是，由于缺少 zlib 库，构建完成时出现错误。我下载并重新构建。这次我收到一个错误消息：
undefined reference to `inflateInit2_'|
undefined reference to `inflateEnd'|
undefined reference to `inflateEnd'|
On the Internet I found the advice to join the linker command -lz, but the compiler refuses throwing the error: cannot find -lz. Does anyone know how to fix it?
在互联网上我找到了加入链接器命令的建议-lz，但编译器拒绝抛出错误：找不到 -lz。有谁知道如何修理它？

Use the option -L<path>to tell the linker where to find libz.so.x.y.z.
使用该选项-L<path>告诉链接器在哪里可以找到libz.so.x.y.z.

you can see where your zlib is installed like this :
您可以像这样查看 zlib 的安装位置：
/sbin/ldconfig -p| grep libz.so
it should find one or more entries if installed, otherwise it will return blank line
如果安装，它应该找到一个或多个条目，否则它将返回空行
