catastrophic error - bits/c++config.h (icpc 19.0.1.144)

[Benjamin_Karl_B_]

Hi,

I am trying to compile a simple program with icpc version 19.0.1.144 (gcc version 8.2.0 compatibility) and I get the following error:

icpc -g -O2 -std=c++17 -I. -c main.cc -o main.o
In file included from main.cc(4):
/usr/include/c++/8/iostream(38): catastrophic error: cannot open source file "bits/c++config.h"
  #include <bits/c++config.h>
                                            ^

If I add the gcc8 include path "-I/usr/include/x86_64-linux-gnu/c++/8", I can compile the code. However, this seems like a bug (I shouldn't have to tell the compiler where it's headers are installed.)

I have also tried using gcc7, but get the same error, i.e.,

icpc -g -O2 -std=c++17 -gxx-name=/usr/bin/x86_64-linux-gnu-g++-7 -I. -c main.cc -o main.o
In file included from main.cc(4):
/usr/include/c++/7/iostream(38): catastrophic error: cannot open source file "bits/c++config.h"
  #include <bits/c++config.h>
                                            ^

I am running on Ubuntu 18.04:

The test program that I am trying to compile is:

int main(int argc, char ** argv) {

  return 0;
} // main

I am curious to know if g++ compiles on this system?

[Benjamin_Karl_B_]

Yes, I can compile with g++ (7,8) and clang++ (5,6) without any issues.

I don't have GCC8.2 installed, but couldn't reproduce it with 7.3.0

On Arch Linux, with GCC 8.2 and Intel 2019 Update 1 (your exact versions) I can't reproduce your problem either.

Since GCC 8.2 isn't the default compiler on Ubuntu 18.04.1 I think it is required to point icpc to your GCC include files, a convenient way to do might be to use the "GXX_INCLUDE" environment variable:

For example on Arch Linux I use

export GXX_INCLUDE=/usr/lib/gcc/x86_64-pc-linux-gnu/7.4.1/include/c++
icpc -gxx-name=g++-7 ...
icc -gcc-name=gcc-7 ...

when using GCC 7 as the backend.
