Error during make gcc: "cp: Permission denied"

What I did

In my initially empty build directory, I configure gcc with

/home/anthony/Documents/gcc-pi/gcc/configure --prefix=/opt/gcc --enable-multilib --disable-shared --enable-static --disable-bootstrap --disable-libstdcxx-pch --enable-languages=all --enable-libgomp --enable-threads=posix --enable-tls --with-system-zlib --with-isl --enable-__cxa_atexit --enable-host-shared CFLAGS='-lpthread -fPIC' CXXFLAGS='-lpthread -fPIC' CPPFLAGS='-fPIC'

I then issue make and after some successful building, the build ultimately fails with the following

make[2]: Entering directory '/home/anthony/Documents/gcc/gcc'mkdir -p ada/bldtools/sinform -f ada/bldtools/sinfo/sinfo.ads ada/bldtools/sinfo/sinfo.adb ada/bldtools/sinfo/xsinfo.adb ada/bldtools/sinfo/csinfo.adbcp -p /home/anthony/Documents/gcc-pi/gcc/gcc/ada/sinfo.ads /home/anthony/Documents/gcc-pi/gcc/gcc/ada/sinfo.adb /home/anthony/Documents/gcc-pi/gcc/gcc/ada/xsinfo.adb /home/anthony/Documents/gcc-pi/gcc/gcc/ada/csinfo.adb ada/bldtools/sinfomake[2]: cp: Permission deniedmake[2]: *** [/home/anthony/Documents/gcc-pi/gcc/gcc/ada/Make-generated.in:44: ada/sinfo.h] Error 127make[2]: Leaving directory '/home/anthony/Documents/gcc/gcc'make[1]: *** [Makefile:4411: all-gcc] Error 2make[1]: Leaving directory '/home/anthony/Documents/gcc'make: *** [Makefile:970: all] Error 2

What I tried

I've tried

  1. sudo make
  2. sudo chmod 777 -R the gcc source and build directories
  3. sudo cp -p /home/anthony/Documents/gcc-pi/gcc/gcc/ada/sinfo.ads /home/anthony/Documents/gcc-pi/gcc/gcc/ada/sinfo.adb /home/anthony/Documents/gcc-pi/gcc/gcc/ada/xsinfo.adb /home/anthony/Documents/gcc-pi/gcc/gcc/ada/csinfo.adb ada/bldtools/sinfod ```

all of which failed at advancing the build. Note that the last command succeeds, but when I try to continue the build after that, it yields the same error.

Any ideas? Thanks in advance.
