[build2] error when trying to compile build2

[Phillip Shelton]

Hi,

I am trying to bootstrap build2 on a work computer.

I am using the following compiler
>>C:\compilers\build2_build\build2-toolchain-0.14.0> c:\compilers\mingw64\bin\g++ --version
g++ (MinGW-W64 x86_64-ucrt-posix-seh, built by Brecht Sanders) 11.2.0
Copyright (C) 2021 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

So I first just tried the following:
>>C:\compilers\build2_build\build2-toolchain-0.14.0>.\build-mingw.bat c:\compilers\mingw64\bin\g++
And got the following:
error: C:\build2\bin\ does not exist

So I changed line 96 of the .bat file to:
set "idir=C:\compilers\build2"

from set "idir=C:\build2"

This got further.

Now I get the this error
..\libbutl\libbutl\process.cxx: In constructor 'butl::process::process(const butl::process_path&, const char**, butl::process::pipe, butl::process::pipe, butl::process::pipe, const char*, const char* const*)':
..\libbutl\libbutl\process.cxx:1386:7: error: 'unique_ptr' was not declared in this scope
1386 |       unique_ptr<char, void (*)(char*)> pevars (
      |       ^~~~~~~~~~
..\libbutl\libbutl\process.cxx:104:1: note: 'std::unique_ptr' is defined in header '<memory>'; did you forget to '#include <memory>'?
 103 | #include <libbutl/process-details.hxx>
  +++ |+#include <memory>
  104 |

Is this because of the version of the compiler?
Will just doing as the note suggests work? Or will I have other unintended problems if I do this?
