pb when I try to compile the kernel

[Francois]

Hi,
Running Fedora 7 on a computer, I tried to compile the latest kernel.
For the first time since I run linux, it fails ;-(
This is the message I get when I run "make xconfig" :

[root at celtes3 linux]# make xconfig
  HOSTCC  scripts/basic/fixdep
  HOSTCC  scripts/basic/docproc
  CHECK   qt
  HOSTCC  scripts/kconfig/conf.o
sed < scripts/kconfig/lkc_proto.h > 
scripts/kconfig/lkc_defs.h 's/P(\([^,]*\),.*/#define \1 (\*\1_p)/'
  HOSTCC  scripts/kconfig/kconfig_load.o
  HOSTCC  scripts/kconfig/kxgettext.o
  SHIPPED scripts/kconfig/zconf.tab.c
  SHIPPED scripts/kconfig/lex.zconf.c
  SHIPPED scripts/kconfig/zconf.hash.c
  HOSTCC  scripts/kconfig/zconf.tab.o
/usr/lib/qt-3.3/bin/moc -i scripts/kconfig/qconf.h -o 
scripts/kconfig/qconf.moc
  HOSTCXX scripts/kconfig/qconf.o
/bin/sh: g++: command not found
make[1]: *** [scripts/kconfig/qconf.o] Erreur 127
make: *** [xconfig] Erreur 2

I tried with another kernel, and same error.
What do I have to do to be able to compile it ? Thanks.
Francois
