guix: point to latest upstream master #24300

pull fanquake wants to merge 1 commits into bitcoin:master from fanquake:reenable_win_guix changing 1 files +1 −1

    Now that Carls fix for binutils and compressed debug sections has been merged into Guix, point our time-machine to the latest commit on Guix master. The Windows builds don’t yet work with this change, but we are now at the point of compiling our own code..

    There must be a difference in the Guix environment, compared to, for example, compiling using GCC 10.3 on Ubuntu Hirsute, which currently works.

    Opening this PR for testing / discussion:

    Yesterday I was building against 4be896d6e0d322b3f5b514c8a2811efcd6a31606 Guix commit, and have got the same error.

    The weirdest part of the error message is

    0... error: request for member 'make_preferred' in 'std::declval<const wchar_t*&>()', which is of non-class type 'const wchar_t*'
    

    Friendly ping @dongcarl @ryanofsky

  5. ryanofsky commented at 6:08 pm on February 9, 2022: member

    Fanquake’s error seems to come from this line (based on init.cpp:143:40: required from here)

    https://github.com/bitcoin/bitcoin/blob/f6ff8d8604f65c4cb5392e2259d77439665867e7/src/init.cpp#L143

    Which happens for the reason we are familiar with that std::fstream does not like fs::path objects

    I’m not sure about the other make_preferred error. The place I see us calling that is

    https://github.com/bitcoin/bitcoin/blob/f6ff8d8604f65c4cb5392e2259d77439665867e7/src/test/util/chainstate.h#L40

    which looks ok to me

    So I guess the solution will be to partially revert fs? That is: std::ofstream -> fs::ofstream.

    So I guess the solution will be to partially revert fs? That is: std::ofstream -> fs::ofstream.

    FWIW, I’ve tried such approaches in some variants without success..

  8. MarcoFalke commented at 6:40 pm on February 9, 2022: member
    Is there any way to reproduce this outside of guix?
  9. hebasto commented at 7:25 pm on February 10, 2022: member

    I’ve made some investigations. The error does not caused by our fs::path class. A similar error happens when using pure std::filesystem::path.

    I’m not sure about the other make_preferred error.

    It happens during template argument substitution in typename _Require = _If_fs_path<_Path>.

    FWIW, in Guix environment the _GLIBCXX_HAVE__WFOPEN macro is undefined.
  11. hebasto commented at 10:08 am on February 11, 2022: member

    @dongcarl

    Might it be because of: https://salsa.debian.org/mingw-w64-team/gcc-mingw-w64/-/blob/2ee26ff4f275384aa6173ada884929db4d2f1bbf/debian/rules#L228

    I’ve verified this assumption.

    Indeed, in Guix environment the _GLIBCXX_FULLY_DYNAMIC_STRING macro is defined to 0 which differs from non-Guix environment where it is defined to 1.

    The following patch:

     0--- a/contrib/guix/manifest.scm

    makes _GLIBCXX_FULLY_DYNAMIC_STRING defined to 1, but the error still exists, unfortunately.

  12. dongcarl commented at 1:08 am on February 12, 2022: member

    Okay leaving a comment here for myself and anyone else who wants to dive in: it seems that _GLIBCXX_FULLY_DYNAMIC_STRING doesn’t really affect this much.

    What does affect it is _GLIBCXX_HAVE__WFOPEN, which is undefined in the Guix environment and defined in the Ubuntu Impish environment. Despite its name it actually affects open and the *fstream constructors, so would match the errors we’re seeing. No --enable-wchar_t=yes does not solve this.

    What does affect it is _GLIBCXX_HAVE__WFOPEN, which is undefined in the Guix environment and defined in the Ubuntu Impish environment. Despite its name it actually affects open and the *fstream constructors, so would match the errors we’re seeing.

    Are mingw headers available at this point https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=libstdc++-v3/crossconfig.m4;h=fe1828835368dd5c2c16a20cf4abc52739e52f30;hb=f00b5710a30f22efc3171c393e56aeb335c3cd39#l200:

    0    AC_CHECK_FUNCS(_wfopen)
    

    ?

    After further investigation, I suspect the following option:

    0                             '("--with-newlib")
    

    I was trying:

     0--- a/contrib/guix/manifest.scm
     1+++ b/contrib/guix/manifest.scm
     2@@ -160,7 +160,7 @@ desirable for building Bitcoin Core release binaries."

     5 (define (make-gcc-with-pthreads gcc)
     6-  (package-with-extra-configure-variable gcc "--enable-threads" "posix"))
     7+  (package-with-extra-configure-variable (package-with-extra-configure-variable gcc "--with-newlib" "no") "--enable-threads" "posix"))
     8 
     9 (define (make-mingw-pthreads-cross-toolchain target)
    10   "Create a cross-compilation toolchain package for TARGET"
    

    but it fails because --with-newlib actually overrides my custom option:

    @dongcarl What is the correct way to build with --without-newlib option?

    A solution suggested in #24348.
