Cannot link to third party Library

dzk-chh — Thu, 14 Apr 2022 07:41:07 GMT

The development board is embedded okmx8mq of forlinx and uses linux5.4.3. When using Basler's pylon library, I can't link to it.

1. I have configured the environment variables.

root@imx8mqvk:/opt# source ./pylon6/bin/pylon-setup-env.sh pylon6

2. Error reporting during operation

./pylonviewer:error while loading shared libraries:libPluginCore.so.1:cannot open shared object file:no such file or directory

3. The library file（libPluginCore.so.1） exists, but the dynamic library is not linked to

4. I added the shared library to the system default library and modified the file----/etc/ls.so.conf,but the error still exist.

thanks

你试试把库路径放到pylon-setup-env.sh 里

问题已解决，非常感谢！灵感来源于pylon-setup-env.sh的提示。

我把/opt/pylon_6.2.******的路径（文件夹）修改为 /opt/pylon ，然后配置好环境变量，把依赖的库复制到/usr/lib下边就，我自己的qt程序就成功了。
