Dear gcc-helper,

Trying to experiment with C++0x , I've downloaded the tarball of GCC 4.3.1. But I'm stuck at the installation...

Please, HELP!

I did, according to the description http://gcc.gnu.org/install/configure.html , the following things:

1. get the MPL (multiple precision library) including source --> OK
2. get the MPFRCPP (which requires MPFR and GMP) --> OK
3. make the object-dir separated from the src dir (for testing) --> OK
4. from within the object-dir : `src dir`/configure --> OK

now just to be sure, I have checked the Makefile which has been generated by the 'configure' command. this contains the following lines:
Quote:
# Directory where sources are, from where we are.
srcdir = ../gcc
gcc_docdir = ../gcc/doc

# Directory where sources are, absolute.
abs_srcdir = /usr/share/gcc-4.3.1/gcc_objectdir/../gcc
abs_docdir = /usr/share/gcc-4.3.1/gcc_objectdir/../gcc/doc

# Top build directory for this package, relative to here.
top_builddir = .

# objdir is set by configure.
# It's normally the absolute path to the current directory.
objdir = /usr/share/gcc-4.3.1/gcc_objectdir
and these are exactly the directories I've created. So it all seems to be OK.

BUT:

I get the following error:

build/genmodes -h> tmp-modes.h
/bin/sh: build/genmodes: No such file or directory


Then when I look in the Makefile just mentioned (the Makefile created in the 'object-dir' by the command 'configure'), I see these lines:
Quote:
insn-modes.c: s-modes; @true
insn-modes.h: s-modes-h; @true
min-insn-modes.c: s-modes-m; @true

s-modes: build/genmodes$(build_exeext)
$(RUN_GEN) build/genmodes$(build_exeext)> tmp-modes.c
$(SHELL) $(srcdir)/../move-if-change tmp-modes.c insn-modes.c
$(STAMP) s-modes

s-modes-h: build/genmodes$(build_exeext)
$(RUN_GEN) build/genmodes$(build_exeext) -h> tmp-modes.h
$(SHELL) $(srcdir)/../move-if-change tmp-modes.h insn-modes.h
$(STAMP) s-modes-h

s-modes-m: build/genmodes$(build_exeext)
$(RUN_GEN) build/genmodes$(build_exeext) -m> tmp-min-modes.c
$(SHELL) $(srcdir)/../move-if-change tmp-min-modes.c min-insn-modes.c
$(STAMP) s-modes-m

There is no file or directory which is called genmodes in the directory "build" (which itself does exist)!!

sniff..... an idea? I don't put any options with 'make' , and I'm just installing it as a native compiler.

Thanks sooooo much in advance.

ps: the full screen output is attached as "GCC431_install_output.txt" , the generated Makefile is attached as well
