Programming on Eclipse

在剛建立完shared或static lib的專案第一次編譯時，都會出現如下方的錯誤:

Building target: libSharedLibParc.so
Invoking: GCC C++ Linker
g++ -shared -o"libSharedLibParc.so"  ./DiskInfo.o   
/usr/bin/ld: ./DiskInfo.o: relocation R_X86_64_32S against `vtable for DiskInfo' 
can not be used when making a shared object; recompile with -fPIC
./DiskInfo.o: could not read symbols: Bad value
collect2: ld returned 1 exit status
make: *** [libSharedLibParc.so] Error 1

其實參考它給與的錯誤訊息，將-fPIC加在GCC C++/C Compiler的Miscellaneous中就可以編過了。

-fPIC(position independent code)用途可以參考link。
