Hi folks! When trying to configure (binutils and gmp, in that case), I'm getting this: === snip === checking how to run the C preprocessor... /lib/cpp configure: error: in `/home/luser/Downloads/binutils-2.26.1/libiberty': configure: error: C preprocessor "/lib/cpp" fails sanity check See `config.log' for more details. make[1]: *** [Makefile:7985: configure-libiberty] Error 1 make[1]: Leaving directory '/home/luser/Downloads/binutils-2.26.1' make: *** [Makefile:846: all] Error 2 === snap ===
Are you attaching the same config.log? If so, something is indeed odd, because looking at your attachment:
config.log This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake. It was created by configure, which was generated by GNU Autoconf 2.64. Invocation command line was $ ./configure ## --------- ## ## Platform. ## ## --------- ## hostname = elux-devel uname -m = x86_64 uname -r = 4.14.39 uname -s = Linux uname -v = #1 SMP Fri Jul 20 13:35:34 CEST 2018
Okay, you've told us your kernel,...
configure:4111: checking for gcc configure:4127: found /usr/local/bin/gcc configure:4138: result: gcc configure:4367: checking for C compiler version configure:4376: gcc --version >&5 gcc (GCC) 5.4.0
and it looks like you are using a self-built gcc,
configure:14766: checking whether to enable maintainer-specific portions of Makefiles configure:14775: result: no configure:15032: creating ./config.status ## ---------------------- ## ## Running config.status. ## ## ---------------------- ##
...
configure: exit 0
but this config.log says that configure ran to completion, without any warning about /lib/cpp failing a sanity check, which makes it hard to see the "more details" that stdout/stderr said we should be looking for in evidence why configure failed.
