Building gcc-8.3.0 into a separate directory from the sources but failed

Building gcc-8.3.0 into a separate directory from the sources but failed

[Jun Leng]

Dear all, I built gcc-8.3.0 into a separate directory from the sources but still failed.

My commands are as follows:
1 cd ..
2 mkdir gcc1
3 cd gcc1
4 ../gcc-8.3.0/configure --prefix=/public/home/lengjun/softwares/gcc1 --with-gmp=/public/home/lengjun/softwares_install_leng/gmp-6.1.0 --with-mpfr=/public/home/lengjun/softwares_install_leng/mpfr-3.1.4 --with-mpc=/public/home/lengjun/softwares_install_leng/mpc-1.0.3  --with-isl=/public/home/lengjun/softwares_install_leng/isl-0.18 --enable-bootstrap --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit  --disable-libunwind-exceptions --enable-gnu-unique-object --enable-linker-build-id --with-linker-hash-style=gnu --enable-languages=c,c++,objc,obj-c++,fortran,ada,go,lto --enable-plugin --enable-initfini-array --disable-libgcj --enable-gnu-indirect-function --with-tune=generic --with-arch_32=x86-64 --build=x86_64-redhat-linux --disable-multilib

5 make
The error is:
configure: error: source directory already configured; run "make distclean" there first

Then I ran make distclean in the path gcc1 and it showed that:
...
make: [local-distclean] Error 1 (ignored)
rmdir texinfo/makeinfo texinfo/po texinfo/util 2>/dev/null
make: [local-distclean] Error 1 (ignored)
rmdir fastjar gcc gnattools gotools libcc1 libiberty 2>/dev/null
make: [local-distclean] Error 1 (ignored)
rmdir texinfo zlib 2>/dev/null
make: [local-distclean] Error 1 (ignored)
find . -name config.cache -exec rm -f {} \; \; 2>/dev/null
make: [local-distclean] Error 1 (ignored)

Then I create another new directory and it still showed the error above.

Can anybody help me?

Best regards,

Jun

If you used git to create the source tree, then using git to clean it is
probably easiest.  Maybe something like
  git clean -f -x -d
assuming that you don't have anything in there that you want to keep.  You
need to get the source tree to the state where git status --ignored shows
no changes.

Or even simpler is to just rm -rf your existing tree and git clone a new
one, and then be careful not to run configure in the source tree again.

I doubt that using make distclean is going to work.

Maybe you did something as weird as using the build directory as the 
becoming install
directory?  So '/public/home/lengjun/softwares/gcc1' was your build 
directory?
