I am trying to build CMake using the instructions in BLFS 8.1. My LFS build is 8.1. Hopefully this is not too verbose, I just want to include anything potentially relevant. The following is what happens initially:
Code:
root [ /sources/xc/cmake-3.9.1 ]# sed -i '/CMAKE_USE_LIBUV 1/s/1/0/' CMakeLists.txt &&
> sed -i '/"lib64"/s/64//' Modules/GNUInstallDirs.cmake &&
>
> ./bootstrap --prefix=/usr \
> --system-libs \
> --mandir=/share/man \
> --no-system-jsoncpp \
> --no-system-librhash \
> --docdir=/share/doc/cmake-3.9.1 &&
> make

CMake 3.9.1, Copyright 2000-2017 Kitware, Inc. and Contributors
Found GNU toolchain
C compiler on this system is: gcc -std=gnu11
---------------------------------------------
Error when bootstrapping CMake:
Cannot find appropriate C++ compiler on this system.
Please specify one using environment variable CXX.
See cmake_bootstrap.log for compilers attempted.
---------------------------------------------
Log of errors: /sources/xc/cmake-3.9.1/Bootstrap.cmk/cmake_bootstrap.log
I tried setting CXX (CXX="g++" and when that failed CXX="/usr/bin/g++") but no use.
The following is the error log cmake_bootstrap.log

I've spent all day on this, and I was able to get past the initial glitch but by ading g++ to line 991 of the file entitled cmake-3.9.1/bootstrap:
Code:
990 # Test CXX compiler
991 cmake_cxx_compiler=g++
It seemed to recognize g++ (Probably!), but it did not get much further before arriving at the following error:
Code:
no such file or directory
#include_next <stdlib.h>
^~~~~~~~~~
compilation terminated.
make: *** [Makefile:4: cmAddCustomCommandCommand.o] Error 1
After hours of tinkering with it, trying older and newer versions etc., I decided perhaps I should reinstall g++. So I did so as per the LFS directions for the 3rd pass minus the removal of the symlink (since that has been done).
GCC passed config but failed to compile with the exact same error
Code:
c -I../../gcc/build -I../../gcc/../include -I../../gcc/../libcpp/include \
-o build/genmddeps.o ../../gcc/genmddeps.c
In file included from ../../gcc/system.h:266:0,
from ../../gcc/genmddeps.c:19:
/usr/include/c++/7.2.0/cstdlib:75:15: fatal error: stdlib.h: No such file or directory
#include_next <stdlib.h>
^~~~~~~~~~
compilation terminated.
make[2]: *** [Makefile:2595: build/genmddeps.o] Error 1
The line referenced to in cstdlib is:
Code:
72 // Need to ensure this finds the C library's <stdlib.h> not a libstdc++
73 // wrapper that might already be installed later in the include search path.
74 #define _GLIBCXX_INCLUDE_NEXT_C_HEADERS
75 #include_next <stdlib.h>
76 #undef _GLIBCXX_INCLUDE_NEXT_C_HEADERS
Something seems wrong with my g++ or corresponding libraries.
I tried reinstalling libstdc++, it succeeded. Still, the same errors when I try to compile CMake, and I tested, GCC too (failed again).
I need to be able to build cmake because some programs that I need depend on it.
Any ideas what may be going wrong?
