| - | ===== Compile Problem ===== | ||
| - | ==== could not read symbols ==== | ||
| - | 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: | ||
| - | <code> | ||
| - | 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 | ||
| - | </code> | ||
| - | 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。\\ | ||
| - | {{:cpp:dll:linux:eclipse_cpp_build_setting_fpic.png|}}\\ | ||
| - | -fPIC(position independent code)用途可以參考[[http://bbs.chinaunix.net/thread-4063737-1-1.html|link]]。 | ||
