I can't succeed in making much further progress based on this. It seems that people think the problem is that I'm creating some conflict by executing commands in the wrong directory. My source code directory is /home/User/gcc-4.6.2/ I run ./contrib/download_prerequisites; inside it. I then create /home/User/objdir/ and cd to this directory. Inside which I run ./../gcc-4.6.2/configure --prefix=/home/User/; which is not inside the source directory, being is /home/User/gcc-4.6.2/ Having configured successfully, I then make clean; make; which provides me with the same error I have been reporting. What should I do from this stage? ---------------------------------------- > Date: Thu, 1 Mar 2012 13:09:04 +0200 > From: kai.ruottu@xxxxxxxxxxx > To: jwakely.gcc@xxxxxxxxx > CC: stargate7thsymbol@xxxxxxxxxx; gcc-help@xxxxxxxxxxx; java@xxxxxxxxxxx > Subject: Re: gcc-4.6.2 can't complete make > > 1.3.2012 2:54, Jonathan Wakely kirjoitti: > > > On 1 March 2012 00:46, Me Myself and I wrote: > >> > >> I have started again, moving objdir outside the gcc-4.6.2 source code directory. > >> > >> My configure completes, however I still get errors which look remarkably like this: > >> > >> > >> /home/User/objdir > >> > >> make install; > >> > >> fib2_ui.c:76:29: error: 'FIB_TABLE_LIMIT' undeclared (first use in this function) > >> fib2_ui.c:76:29: note: each undeclared identifier is reported only once for each function it appears in > >> make[5] *** [fib2_ui.lo] Error 1 > >> make[5] Leaving directory '/home/User/gcc-4.6.2/objdir/gmp/mpn' > >> make[4] ***all-recursive] Error 1 > >> make[4] Leaving directory '/home/User/gcc-4.6.2/objdir/gmp' > >> make[3] *** [all] Error 2 > >> make[3] Leaving directory '/home/User/gcc-4.6.2/objdir/gmp' > >> make[2] *** [all-stage1-gmp] Error 2 > >> make[2] Leaving directory '/home/User/gcc-4.6.2/objdir' > >> make[1] *** [stage1-bubble] Error 2 > >> make[1] Leaving directory '/home/User/gcc-4.6.2/objdir' > >> make: *** [all] Error 2 > > > > This error comes from running inside the source dir.
