Error while loading shared libraries #750

Closed Huang-XN closed 3 months ago

Huang-XN commented 4 months ago

Hi there,

I have successfully installed Ipopt following the instructions. But when I ran ipopt -v or ipopt -h, it always reported an error as follow: ipopt: error while loading shared libraries: libcoinhsl.so.2: cannot open shared object file: No such file or directory.

My system is Ubuntu 22.04.4 LTS, 64 bit.

Could you tell me how to solve it?

Add the path with the Ipopt libraries to your library search path, e.g., LD_LIBRARY_PATH environment variable.
