configure: error: The ARM target needs to support floating point instructions.
There were various problems during compilation, I asked about AI tools (ChatGPT, DeepSeek) and ended up stuck here, so I started this issue to ask for help.
My device is Xiaomi Pad 5, and using operate system Arch Linux Arm (rolling).
This parameter is wrong: --host=arm64ec-w64-mingw32
Thanks a lot, I'll try build again later.
I seem to have encountered the same problem. When I use the following command, I get the following error。 ../configure --disable-tests --with-mingw=clang --enable-archs=arm64ec,aarch64 `checking build system type... aarch64-unknown-linux-gnu checking host system type... aarch64-unknown-linux-gnu checking for gcc... gcc checking whether the C compiler works... yes checking for C compiler default output file name... a.out checking for suffix of executables... checking whether we are cross compiling... no checking for suffix of object files... o checking whether the compiler supports GNU C... yes checking whether gcc accepts -g... yes checking for gcc option to enable C11 features... none needed checking for g++... g++ checking whether the compiler supports GNU C++... yes checking whether g++ accepts -g... yes checking for g++ option to enable C++11 features... none needed checking for cpp... cpp checking for ld... ld checking for the directory containing the Wine tools... checking for flex... flex checking whether flex is recent enough... yes checking for bison... bison checking whether bison is recent enough... yes checking for strip... strip checking whether ln -s works... yes checking for pkg-config... pkg-config checking for msgfmt... msgfmt checking whether msgfmt supports contexts... yes checking for i386_set_ldt in -li386... no checking for special C compiler options needed for large files... no checking for _FILE_OFFSET_BITS value needed for large files... no checking for stdio.h... yes checking for stdlib.h... yes checking for string.h... yes checking for inttypes.h... yes checking for stdint.h... yes checking for strings.h... yes checking for sys/stat.h... yes checking for sys/types.h... yes checking for unistd.h... yes checking for CL/cl.h... yes checking for EGL/egl.h... yes checking for OpenCL/opencl.h... no checking for arpa/inet.h... yes checking for arpa/nameser.h... yes checking for asm/termbits.h... yes checking for asm/types.h... yes checking for asm/user.h... no checking for elf.h... yes checking for gettext-po.h... no checking for link.h... yes checking for linux/cdrom.h... yes checking for linux/filter.h... yes checking for linux/hdreg.h... yes checking for linux/hidraw.h... yes checking for linux/input.h... yes checking for linux/ioctl.h... yes checking for linux/major.h... yes checking for linux/param.h... yes checking for linux/serial.h... yes checking for linux/types.h... yes checking for linux/ucdrom.h... no checking for linux/wireless.h... yes checking for lwp.h... no checking for mach-o/loader.h... no checking for mach/mach.h... no checking for machine/cpu.h... no checking for machine/sysarch.h... no checking for mntent.h... yes checking for netdb.h... yes checking for netinet/in.h... yes checking for netinet/in_systm.h... yes checking for netinet/tcp.h... yes checking for netinet/tcp_fsm.h... no checking for pcap/pcap.h... yes checking for port.h... no checking for pwd.h... yes checking for sched.h... yes checking for scsi/scsi.h... yes checking for scsi/scsi_ioctl.h... yes checking for scsi/sg.h... yes checking for sys/attr.h... no checking for sys/auxv.h... yes checking for sys/cdio.h... no checking for sys/epoll.h... yes checking for sys/event.h... no checking for sys/extattr.h... no checking for sys/filio.h... no checking for sys/ipc.h... yes checking for sys/link.h... no checking for sys/modem.h... no checking for sys/mtio.h... yes checking for sys/param.h... yes checking for sys/prctl.h... yes checking for sys/ptrace.h... yes checking for sys/queue.h... yes checking for sys/random.h... yes checking for sys/resource.h... yes checking for sys/scsiio.h... no checking for sys/shm.h... yes checking for sys/signal.h... yes checking for sys/socketvar.h... yes checking for sys/sockio.h... no checking for sys/statvfs.h... yes checking for sys/strtio.h... no checking for sys/syscall.h... yes checking for sys/sysinfo.h... yes checking for sys/times.h... yes checking for sys/uio.h... yes checking for sys/user.h... yes checking for sys/utsname.h... yes checking for sys/vnode.h... no checking for sys/xattr.h... yes checking for syscall.h... yes checking for utime.h... yes checking for valgrind/memcheck.h... no checking for valgrind/valgrind.h... no checking for sys/mkdev.h... no checking for sys/sysmacros.h... yes checking for sys/conf.h... no checking for sys/mount.h... yes checking for sys/statfs.h... yes checking for sys/user.h...

That's a different issue, you simply don't use a clang with arm64ec support, please follow the compilation instructions
