Shared object build issue
Not sure if this is strictly a code problem but since it flags one of my functions I trying here 1st, admin can always move the thread if it's deemed unrelated. So I finally settled on how I want my abstracted character reading object to be like and in turn modified all my related test projects to use a shared library, only the library in question is not completing the build process, here's the output:
Code:
make expr.run (in directory: /media/lee/ZXUIJI_1TB/github/mc)
cc -shared -Wall -D OUT=libnext.so -o libnext.so next.c
makefile:67: recipe for target 'libnext.so' failed
/usr/bin/ld: /tmp/ccsjP35t.o: relocation R_X86_64_PC32 against symbol `nextc_validate' 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
make: *** [libnext.so] Error 1
Compilation failed.

Any ideas on why it's flagging that one function?
