[vbox-dev] building VirtualBox source with latest linux build toolchain??

[John Lumby]

I am trying to build VirtualBox source on my up-to-date archlinux amd-64bit system, which has toolchain versions
gcc/g++ 13.2.1 20230801
binutils     2.41.0

my build commands are  

./configure --disable-hardening --build-libxml2 --build-libcurl --disable-alsa --disable-pulse --build-headless --enable-vnc --with-iasl=/opt/acpica_local/bin/iasl --disable-vmmraw --disable-java --disable-qt --disable-docs      /*   successful */

kmk KBUILD_VERBOSE=2 --jobs=2 all    /*  (the one which fails   */

I have tried building each of  7.0.14a and current trunk checked out by svn,    with different failures in each case,       but each possibly indicating some kind of incompatibility with one of the compiler/assemblers

For 7.0.14a ,     what I think is the fatal problem is this :

g++ -c -O2 -g -pipe -pedantic -Wshadow -Wall -Wextra -Wno-missing-field-initializers -Wno-unused -Wno-trigraphs -fdiagnostics-show-option -Wno-unused-parameter -Wlogical-op -Wno-variadic-macros -Wno-long-long -Wunused-variable -Wunused-function -Wunused-label -Wunused-parameter -Wno-overloaded-virtual -Wno-array-bounds -Wno-ignored-qualifiers -Wno-variadic-macros -O2 -mtune=generic -fno-omit-frame-pointer -fno-strict-aliasing -fvisibility=hidden -DVBOX_HAVE_VISIBILITY_HIDDEN -DRT_USE_VISIBILITY_DEFAULT -std=c++11 -fvisibility-inlines-hidden -fno-exceptions -fno-rtti -ffunction-sections -fdata-sections -fno-pie -fno-merge-constants -ffreestanding -fno-stack-protector  -m64 -Wno-shadow -I/opt/VirtualBox-7.0.14/src/VBox/Additions/x11/x11include/XFree86-4.3/Xserver -I/opt/VirtualBox-7.0.14/src/VBox/Additions/x11/x11include/XFree86-4.3 -I/opt/VirtualBox-7.0.14/src/VBox/Additions/x11/x11include/XFree86-4.3/X11 -I/opt/VirtualBox-7.0.14/out/linux.amd64/release/obj/VBoxGuestR3LibXFree86/dtrace -I/opt/VirtualBox-7.0.14/include -I/opt/VirtualBox-7.0.14/out/linux.amd64/release -DVBOX -DVBOX_OSE -DVBOX_WITH_64_BITS_GUESTS -DRT_OS_LINUX -D_FILE_OFFSET_BITS=64 -DRT_ARCH_AMD64 -D__AMD64__ -DVBOX_WITH_DEBUGGER -DIN_RING3 -DIN_GUEST -DIN_GUEST_R3 -DIN_RT_R3 -DIN_RT_STATIC -DGC_ARCH_BITS=64 -DRT_NEED_NEW_AND_DELETE -DVBOX_GUESTR3XF86MOD -DRTMEM_NO_WRAP_TO_EF_APIS -DVBOX_WITH_HGCM -DVBOX_VBGLR3_XFREE86 -DRTMEM_NO_WRAP_TO_EF_APIS -DVBOX_WITH_GUEST_PROPS -DVBOX_WITH_DRAG_AND_DROP -DVBOX_WITH_DRAG_AND_DROP_GH -DHC_ARCH_BITS=64 -Wp,-MD,/opt/VirtualBox-7.0.14/out/linux.amd64/release/obj/VBoxGuestR3LibXFree86/VBoxGuestR3LibRuntimeXF86.o.dep -Wp,-MT,/opt/VirtualBox-7.0.14/out/linux.amd64/release/obj/VBoxGuestR3LibXFree86/VBoxGuestR3LibRuntimeXF86.o -Wp,-MP -o /opt/VirtualBox-7.0.14/out/linux.amd64/release/obj/VBoxGuestR3LibXFree86/VBoxGuestR3LibRuntimeXF86.o /opt/VirtualBox-7.0.14/src/VBox/Additions/common/VBoxGuest/lib/VBoxGuestR3LibRuntimeXF86.cpp

for current trunk,       there is no obvious single cause of overall failure  -    it is confusing (to me).
I see four lines at various places all saying
: error: warnings being treated as errors
'
the last of these occurs near the end is is preceded by

kmk: /usr/lib64/qt6/bin/lrelease: Command not found
kmk: *** [/opt/VirtualBox-rev102907/kBuild/units/qt6.kmk:612: /opt/VirtualBox-rev102907/out/linux.amd64/release/obj/VirtualBoxAPI/qtnls/VirtualBoxAPI_ru.qm] Error 127
kmk: *** Waiting for unfinished jobs....
: error: warnings being treated as errors

my system does have qt6 and there is a directory /usr/lib64/qt6/bin with about 20 executables in it,  none of which is lrelease whatever that is,      and my system does have an executable file /sbin/lrelease

Since I don't understand these failures and also don't see any obvious corrective action I can take,   I am wondering if my archlinux build environment is somehow too new?      Has anyone else built VirtualBox source with gcc 13.2.1?
