In order to upgrade a VortexDX86 custom linux with a gcc 3.2.3 compiler, Im trying to built the GCC 5.2.0 compiler to support the latest C++ 11 standard.I have downloaded its source code from gcc.gnu.org and did the standard linux package builder based on the this GNU link:$ mkdir ../gcc-build$ cd    ../gcc-build$ ../gcc-5.2.0/configure --prefix=/usr --disable-multilib --with-system-zlib --enable-languages=c,c++The configuration runs fine. The I do:$ makeAnd Im getting the following error:    make[3]: Entering directory `/home/ftp/pub/gcc-5.2.0/host-i586-pc-linux-gnu/gcc'g++ -c   -g -DIN_GCC    -fno-exceptions -fno-rtti -fasynchronous-unwind-tables -W -Wall -Wwrite-strings -Wcast-qual -Wno-format -Wmissing-format-attribute -Woverloaded-virtual -fno-common  -DHAVE_CONFIG_H -DGENERATOR_FILE -I. -Ibuild -I../.././gcc -I../.././gcc/build -I../.././gcc/../include  -I../.././gcc/../libcpp/include  \    -o build/genmddeps.o ../.././gcc/genmddeps.ccc1plus: warning: -Wmissing-format-attribute ignored without -WformatIn file included from ../../gcc/genmddeps.c:19:../../gcc/system.h:201:19: string: No such file or directory../../gcc/system.h:218:22: algorithm: No such file or directory../../gcc/system.h:219:20: cstring: No such file or directory../../gcc/system.h:220:20: utility: No such file or directory../../gcc/system.h:249:19: cstdlib: No such file or directorymake[3]: *** [build/genmddeps.o] Error 1make[3]: Leaving directory `/home/ftp/pub/gcc-5.2.0/host-i586-pc-linux-gnu/gcc'make[2]: *** [all-stage1-gcc] Error 2make[2]: Leaving directory `/home/ftp/pub/gcc-5.2.0'make[1]: *** [stage1-bubble] Error 2make[1]: Leaving directory `/home/ftp/pub/gcc-5.2.0'make: *** [all] Error 2After that the make procedure aborts. Ive installed all the dependencies (tcl, expect, dejagnu, perl, m4, gmp, mpfr and mpc) and I dont know what is missing.As said, the original Vortex linux has a gcc 3.2.3 compiler version already installed.I need to solve that but I dont know where to start from. It seens to have confusion with the own gcc libraries....Help appreciated to solve that.
