      Description

       

      I am using KISS Linux, a musl-based, source distribution. When building with gcc (9, 10), everything completes successfully. 

      When building with a (gcc-independent) llvm install (using llvm, clang, libc++, lld, etc.), I get the following error message when building qt5-base. It occurs in the Network portion of the build:

      In file included from kernel/qhostinfo_unix.cpp:54:

          fd = ::accept4(s, addr, static_cast<QT_SOCKLEN_T *>(addrlen), sockflags);

      How I am configuring qt5-base:

      ./configure \
          -confirm-license \
          -opensource \
          -prefix /usr \
          -docdir /usr/share/doc/qt \
          -headerdir /usr/include/qt \
          -archdatadir /usr/lib/qt \
          -datadir /usr/share/qt \
          -sysconfdir /etc/xdg \
          -examplesdir /usr/share/doc/qt/examples \
          -nomake examples \
          -nomake tests \
          -platform linux-clang-libc++ \
          -optimized-qmake \
          -no-libudev \
          -no-separate-debug-info \
          -no-pch \
          -no-dbus \
          -no-accessibility \
          -no-gtk \
          -no-glib \
          -system-libjpeg \
          -system-libpng \
          -system-sqlite \
          -system-zlib \
          -system-freetype \
          -system-harfbuzz \
          -silent
      

      I have tested this with both llvm 10 as well as the latest master branch on Github. I have not yet tested with llvm 9 - I can (and will), but it will take about a day to get it. 

       

      What's interesting is I have to manually specify my platform when using llvm. Otherwise, I get errors about missing gcc. Testing with both platform linux-clang and linux-clang-libc++ results in identical errors.
