GCC fails to compile - Chapter 6.14 - C preprocessor "/lib/cpp" fails sanity check
 

While in the chrooted environment, at the stage of GCC 4.3.2 compilation this error was produced and make failed.

I have attached the config.log file. I searched for this and found that this error was common at the ncurses compilation stage, and usually because there is no c++ compiler. But isn't that what is being compiled at this stage..? Or does it mean that the host system does not have c++...? the host is Arch linux and has gcc 4.3.2.

Until this error everything went as per book, including the running of all test suites for previous packages.

Is there a way out..?

i can't understand why you want to compile 4.3.2 when you already have 4.3.2? there is little advantage in recompiling gcc unless you can't install a binary package, you will get bits of one gcc in /usr/bin and others in /usr/local/bin, also it takes a long time and rather too much disk space.

have you created a directory called (say) /usr/local/build/
then done cd /usr/local/build/
finally sh ../gcc4.3.2/configure ; make
?
if you are sick of waiting for gcc to compile things a native compile won't help much - use tcc which is about 20 times faster, but is still a little wobbly.
