与 qt pcl 和 vtk 的链接错误

Question

我正在尝试编译 here 中描述的 PCL 教程，但我遇到了这些链接错误。

CMakeList 文件中是否缺少任何内容？

Answer 1

您正在链接的 PostgreSQL 库缺少 openssl，您可以使用

进行检查

ldd /usr/lib/libpq.so.5

它应该报告类似

的内容

libssl.so.1.0.0 => not found

与 vtk 相同，但未找到有效的 TIFF 库。

首先，检查是否同时安装了openssl和tiff库，如果仍然链接失败，请检查版本是否正确。

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

第三，手动强制您的项目加载库标志（从命令行 CMAKE_MODULE_LINKER_FLAGS / CMAKE_SHARED_LINKER_FLAGS 或在 target_link_libraries 指令中）。

Answer 2

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，这样您的路径变量中的 link 在扫描期间对于 cmake 是不正确的。然后使用 sudo apt-get install qt5-default 安装 qt5-default 因为这解决了我的两个错误。然后 re运行 cmake 现在它应该在正确的位置检测到 qt5（即不在 anaconda 路径中）。

现在运行 make 然后最后你可以将 anaconda-temp 重命名为 anaconda 以便它对应于你的路径和 bashrc 中的值并且一切照常。

Answer 3

要解决 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

Answer 4

我认为你应该从你的系统路径中删除 ananconda3。对我来说，我只是将它从 ~/.bashrc 文件中删除。一切正常。
