undefined symbol: IPinYouExp_OnlineSimulation while running "make"

[sreedal]

Hi, Was trying to run the code using the steps detailed in Readme. Got stuck at "make" as symbol loading failed when trying to install the IPingYouExp module. I can see the symbols exported from the rcppexports.cpp file. Where is this symbol defined?

Exact error looks like:

Error: package or namespace load failed for ‘IPinYouExp’ in dyn.load(file, DLLpath = DLLpath, ...):
unable to load shared object '/usr/local/lib/R/site-library/IPinYouExp/libs/IPinYouExp.so':
/usr/local/lib/R/site-library/IPinYouExp/libs/IPinYouExp.so: undefined symbol: IPinYouExp_OnlineSimulation
Error: loading failed
Execution halted
ERROR: loading failed

• removing ‘/usr/local/lib/R/site-library/IPinYouExp’

Thanks,
Sreedal
