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: In file included from ../../include/QtNetwork/5.15.0/QtNetwork/private/qnet_unix_p.h:1: ../../include/QtNetwork/5.15.0/QtNetwork/private/../../../../../src/network/socket/qnet_unix_p.h:120:29: error: cannot initialize a parameter of type 'socklen_t *' (aka 'unsigned int *') with an rvalue of type 'int *' fd = ::accept4(s, addr, static_cast<QT_SOCKLEN_T *>(addrlen), sockflags); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /usr/include/sys/socket.h:387:68: note: passing argument to parameter here int accept4(int, struct sockaddr *__restrict, socklen_t *__restrict, int); ^ 1 error generated. make[2]: *** [Makefile:21735: .obj/qhostinfo_unix.o] Error 1 make[2]: Leaving directory '/tmp/build-25556/qt5/src/network' make[1]: *** [Makefile:245: sub-network-make_first] Error 2 make[1]: Leaving directory '/tmp/build-25556/qt5/src' make: *** [Makefile:51: sub-src-make_first] Error 2

How I am configuring qt5-base:

-opensource \
-prefix /usr \
-docdir /usr/share/doc/qt \
-headerdir /usr/include/qt \
-archdatadir /usr/lib/qt \

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.
