   Is there an existing issue for this?

   • I have searched the existing issues

   Current behaviour

   building depends for native platform configure fails to find usable gcc version because of -V -qversion, etc… confusion this looks like a scripting error

   Expected behaviour

   finds current version of gcc on this host of 10.5.0

   Steps to reproduce

   on focal32 host git clone https://github.com/bitcoin/bitcoin cd bitcoin git checkout v27.1 cd depends make

   Relevant log output

   config.log

   How did you obtain Bitcoin Core

   Compiled from source

   What version of Bitcoin Core are you using?

   v27.1

   Operating system and version

   focal32

   Machine specifications

   ubuntu focal32 intel Atom N280 2 gigs ram 1T disk autoconf 2.69 automake 1.16.1 gcc 10.5.0 python3 3.9.5

   Did all that, does not make any difference executing this command line for depends make HOST=i686-pc-linux-gnu -j8

   however, config.log says this, see attached configure:3745: $? = 0 configure:3734: gcc -m32 -v >&5 Using built-in specs.

   Note last line, all say x86_64-linux-gnu config.log attached config.log

   The error remains the same, can not determine version of compiler

   Last run was attempt at cross compile on ubuntu 18.04 64 bit host attempting cross compile Xeon X5690 192 gigs memory 1 T disk autoconf 2.69 automake 1.16.1 gcc 10.3.0 python3 3.6.9

   seems like a no-win situation, X64 won’t do the 32 bit build and the focal-32 system gcc-10.5 can not find ‘cc1’ gcc -print-prog-name=cc1 does not provide a path

   suggestions?

   taking a look at focal32 expected path for cc1, it is not there. Installed gcc 10.5.0 once again and succeeded in populating /usr/lib/gcc/i686-linux-gnu/10/cc1 works now on focal32

   However the failure to cross compile on the x64 platform is an issue

   –build=x86_64-linux-gnu –host=x86_64-linux-gnu –target=x86_64-linux-gnu from the config log does not look right to me for an 1686 cross build

    Do I understand correctly that you has resolved the initial issue mentioned in the top comment and faced another one?

    If so, please close this issue and open a new one.

    Ok, will open new issue cross compiling X64 => i686 32 bit
