Hi All,
When I using the innovus to synthesis the clock tree using the following command:
create_ccopt_clock_tree_spec -filename ccopt.spec
source ccopt.spec
ccopt_design -cts
I found the errors shown below:
**ERROR: (IMPCCOPT-3092): Couldn't load external LP solver library. Error returned:

It seems that some important library is missing.
The version I am using is Innovus v17.11-s080_1 (64bit) under centos 6.9
Could anyone meet similar problems before and have some solutions?
Best regards,
