Hi, when i install the popins2 software, i meet a question as follows:

Hello @pengyan19 ,
I saw this error message once before using GCC 7.3.0 for compiling PopIns2. My ad hoc fix at that time is described in the PopIns2 Troubleshooting / FAQ at Q4.
With the current version 0.13.0 of PopIns2, please attempt to append -D_GLIB_CXX_USE_CXX11_ABI=0 to any of the CXXFLAGS (e.g. any of line 25-29 in the Makefile).
Out of curiosity, what compiler + version are you using?
