Relocation R_X86_64_PC32 against symbol `_ZTI12SimpleVector' can not be used when making a shared object; recompile with -fPIC

Dear all

A got the following error with catkin_make:

/usr/bin/c++ -fPIC -std=c++11  -g -fPIC -O3 -Wall -O3 -Wall  -shared -Wl,-soname,libhkust_pl_ooqp_itf.so -o

/libooqpgensparse.a(QpGenSparseSeq.o): relocation R_X86_64_PC32 against symbol `_ZTI12SimpleVector' can not be 
used when making a shared object; recompile with -fPIC

What I did is compile OOQP and copy the requested lib and .h in the corresponding EPSILON directories. But I still have this message asking me to compile with -fPIC - meaning recompile OOQP with -fPIC?

Thank you for your help
