I am building my own linux system from scratch.
As I am a beginner I don't know much about the error, and I've tried some ways, but still I am unable to solve this. I came across a step to compile gcc.
The command I used to compile is
CC=$LFS_TGT-gcc \
CXX=$LFS_TGT-g++\
AR=$LFS_TGT-ar \
RANLIB=$LFS_TGT-ranlib \
../gcc-7.3.0/configure \
--prefix=/tools \
--with-local-prefix=/tools \
--with-native-system-header-dir=/tools/include \
--enable-languages=c,c++ \
--disable-libstdcxx-pch \
--disable-multilib \
--disable-bootstrap \
--disable-libgomp
When I run make it gives the following error

Can anyone help me to solve this? Any ideas are appreciated.
If you look at this output you will see "configure" is not able to find some headers :
checking for ANSI C header files... no
checking for sys/types.h... no
checking for sys/stat.h... no
checking for stdlib.h... no
checking for string.h... no
checking for memory.h... no
And on my system I have this header file. So, I suspect, you're system need at this step to find those headers to be able to compile "gcc"
ls -l /usr/include/stdlib.h
-rw-r--r--. 1 root root 34030 Aug 7 2019 /usr/include/stdlib.h
Seem like you have try to say to "configure" that your header is located there :
--with-native-system-header-dir=/tools/include
Please double check configure.log if the right "-I" was used by the compiler, and this header exist.
