Qt 6.8.3 build fails for arm64 when compiled using gcc cross compiler x86_64-aarch64 toolchain.
-
I have,
Host OS: RockyLinux8.10(x86_64)
cross compiler toolchain: gcc-arm-10.2-2020.11-x86_64-aarch64-none-linux-gnu
sysroot used from a docker container for required arm64 packages: FROM --platform=linux/arm64 arm64v8/debian:12
I was able to build Qt6.8.3 for x86_64 on the RockyLinux8.10 with gcc-toolset-12(gcc 12.2.1)In src/qtbase/src/corelib/io/qstorageinfo_linux.cpp
static inline quint64 mountIdForPath(int fd)
{
if (fd < 0)
return 0;
#if defined(STATX_BASIC_STATS) && defined(STATX_MNT_ID)
// STATX_MNT_ID was added in kernel v5.8
struct statx st;
int r = statx(fd, "", AT_EMPTY_PATH | AT_NO_AUTOMOUNT, STATX_MNT_ID, &st);
if (r == 0 && (st.stx_mask & STATX_MNT_ID))
return st.stx_mnt_id;
#endif
return 0;
}Error:

Operation aborted.In gcc-arm-11.2-2022.02-x86_64-aarch64-none-linux-gnu, ./gcc-arm-11.2-2022.02-x86_64-aarch64-none-linux-gnu/aarch64-none-linux-gnu/libc/usr/include/bits/statx-generic.h:43:# define STATX_MNT_ID 0x1000U macro defined. But in ./gcc-arm-11.2-2022.02-x86_64-aarch64-none-linux-gnu/aarch64-none-linux-gnu/libc/usr/include/linux/stat.h struct statx does has stx_mnt_id(Mismatch in headers.)
In docker rootfs which I am providing as --sysroot while compilation, /usr/include/linux/stat.h "struct statx" has stx_mnt_id variable and /usr/include/bits/statx-generic.h define any STATX_MNT_ID macro. Both are there.
Please let me know how to fix this issue, i tried downgrading the cross compiler to gcc-arm-10.2-2020.11-x86_64-aarch64-none-linux-gnu which doesn't define STATX_MNT_ID, but still same issue is seen.
Thanks

Looks like the feature STATX_MNT_ID was detected even your system does not support it. I would simply ifdef it out so the function returns 0

@Christian-Ehrlicher I am now building Qt inside a podman container running on arm64 arch using qemu emulator on top of x86_64 host.
I was able to build Qt 6.8.3 without QtWebengine and QtPdf. When I enabled this two components of Qt, my build is failing with "Too many open files" error in the middle of the build. How to resolve this. I tried reducing job count to 1, still I am seeing this issue. -

Thanks for the reply @Christian-Ehrlicher ,
may be dump question , can we install the installer that you have shared for arm64 installer(https://download.qt.io/official_releases/online_installers/) on the podman container directly ?on top of that can we customize the other lib like openssl,icu versions is it possible ?
