[Message part 1 (text/plain, inline)]

GCC in Fedora Linux does not use --enable-default-pie by default, so
I will encounter the following errors when running the build.sh:


$ ./build.sh c     
Building c
/usr/bin/ld: parser.o: relocation R_X86_64_32S against `.rodata' can
not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: failed to set dynamic section sizes: bad value collect2:
error: ld returned 1 exit status cp: cannot stat 'libtree-sitter-c.so':
No such file or directory

Following are my gcc configure information:

$ gcc -v
Using built-in specs.

version 12.2.1 20221121 (Red Hat 12.2.1-4) (GCC) 

I added -fPIC option in build.sh.
