我正在尝试编译此处描述的PCL教程，并且遇到了这些链接错误。

CMakeList文件中缺少任何内容吗？

Answer 1

您要链接的PostgreSQL库缺少openssl，您可以使用以下命令进行检查

ldd /usr/lib/libpq.so.5

它应该报告类似

libssl.so.1.0.0 => not found

与vtk相同，但是找不到有效的TIFF库。

首先，检查您是否同时安装了openssl和tiff库，如果链接仍然失败，请检查版本是否正确。

其次，如果所有库都已安装，请检查是否来自正确的体系结构（全部32位或全部64位）。

三，手动强制项目加载库的标志（包括命令行CMAKE_MODULE_LINKER_FLAGS / CMAKE_SHARED_LINKER_FLAGS或target_link_libraries指令）。

如评论中所述，anaconda是问题所在。

将您的anaconda文件夹重命名为anaconda-temp，以便您的路径变量中的链接在扫描期间对于cmake不正确。 然后安装qt5-default使用sudo apt-get install qt5-default为我的情况下解决了这两个错误。 然后重新运行cmake ，现在它应该在正确的位置（即不在anaconda路径中）检测到qt5。

现在运行make，最后可以将anaconda-temp重命名为anaconda，使其与您的路径和bashrc中的值相对应，并且照常营业。

为了解决TIFF 4.0的问题，您可以尝试

cd $HOME/Downloads
wget http://old-releases.ubuntu.com/ubuntu/pool/universe/t/tiff3/libtiff4_3.9.7-2ubuntu1_amd64.deb
sudo dpkg -i libtiff4_3.9.7-2ubuntu1_amd64.deb 
sudo ldconfig

对我来说，您应该从系统路径中删除ananconda3。 对我来说，我只是将它从〜/ .bashrc文件中删除。 而且一切正常。
