hi all
my problem is in making .so file in codeblocks , the project that make my .so file in older version(32 bit) is failed with following errors in new version(64 bit)

g++ -Wall -fexceptions -g -Iinclude -c /home/amini/codes/testr/main.cpp -o obj/Debug/main.o
g++ -Wall -fexceptions -g -Iinclude -c /home/amini/codes/testr/src/tester.cpp -o obj/Debug/src/tester.o
g++ -shared  obj/Debug/main.o obj/Debug/src/tester.o  -o bin/Debug/libtestr.so -fPIC  
/usr/bin/ld: obj/Debug/src/tester.o: relocation R_X86_64_PC32 against symbol `_ZTV6tester' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: bad value
collect2: error: ld returned 1 exit status

What I have tried:

when I add command to compilor option only the last command line get the -fPIC
how can I add it to all commands for making all object files,
I tested it in linux terminal it solves my problem

Edit your make files or set it as a global variable, as described in the g++ documentation.

Sorry, no idea, I have never used codeblocks. But again I would suggest you check the documentation.

Solution 1

by adding the -fPIC to compiler option the problem does not solve because other object files don't make with that option then you should go to setting> compiler> other setting> advance option and add -fPIC there

Solution 2

I found that closing Code::Blocks, opening it again and rebuilding my project worked.
