No, don't configure in the source directory: https://gcc.gnu.org/wiki/FAQ#configure But otherwise yes, the fact you need to configure before running make is so obvious that apparently we took it for granted :-) And it hasn't been necessary to run 'make bootstrap' for years, just running 'make' does exactly the same thing now. > > 2) That's what I did: > > $ ./configure --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu > --target=x86_64-pc-linux-gnu > --prefix=/arch/x86_64-linux-gnu/gnu-inst-gcc/testing --enable-shared > --enable-nls --enable-threads=posix --enable-__cxa_atexit --disable-multilib > --with-as=/arch/x86_64-linux-gnu/gnu-inst-binutils/2.38/bin/as > --with-ld=/arch/x86_64-linux-gnu/gnu-inst-binutils/2.38/bin/ld > --with-gmp=/arch/x86_64-linux-gnu/gnu-inst-gcc/testing > --with-mpfr=/arch/x86_64-linux-gnu/gnu-inst-gcc/testing > --with-mpc=/arch/x86_64-linux-gnu/gnu-inst-gcc/testing > --with-isl=/arch/x86_64-linux-gnu/gnu-inst-gcc/testing > --enable-languages=c,c++,objc,obj-c++,lto,jit,fortran,go,d,m2 > --enable-host-shared 2>&1 | tee log0 This seems unnecessarily overcomplicated.
