[odb-users] Error when compiling ODB compiler in 2.5.0-b25 on Windows

[DEMBROGE Michael]

Hello,

I'm getting the following error when I try to build the ODB compiler for ODB 2.5.0-b25:
odb-2.5.0-b.25\build\root.build:37:5: error: ODB compiler can only be built with GCC.

The issue is that I'm configuring it to use gcc, but for some reason, in Windows, it's setting the compiler to 'msvc' (see below).

Here is a summary of my procedure (from https://codesynthesis.com/products/odb/doc/install-build2.xhtml):

Step 1: create folder -
c:\odb-build>bpkg create -d odb-mingw cxx^
More? Config.cxx=gcc^
More? Config.cc.coptions=-O2^
More? Config.install.root=c:\build2
created new configuration in C:\odb-build\odb-mingw\
  uuid: e7166948-dcad-4427-a7b4-9301b12691b0
  type: target

Step 2: download source
C:\odb-build>cd odb-mingw
C:\odb-build\odb-mingw>bpkg build odb at https://pkg.cppget.org/1/beta<mailto:odb at https://pkg.cppget.org/1/beta>

info: while configuring odb

I then found the line in root.build where this test was failing:
if ($cxx.id != 'gcc')
    fail 'ODB compiler can only be built with GCC'

My next step was to make a slight modification to root.build to output $cxx.id:
if ($cxx.id != 'gcc')
    fail 'ODB compiler can only be built with GCC. cxx.id = ' $cxx.id

I then re-ran the 'build' command:
C:\odb-build\odb-mingw>bpkg build odb at https://pkg.cppget.org/1/beta<mailto:odb at https://pkg.cppget.org/1/beta>

odb-2.5.0-b.25\build\root.build:37:5: error: ODB compiler can only be built with GCC. cxx.id =  msvc

Does anyone have any ideas as to what is going wrong? I have installed gcc, but maybe it's missing something else?

TIA,
