Is it due to using -ffat-lto-objects? I've never used this option, so I don't really understand why do you need it, but it clearly doesn't work, at least in combination with mold.
In any case, I don't think there is anything we can possibly do about it, so the obvious advice would be to not use one or the other.

I will try the build without -ffat-lto-objects. ('-ffat-lto-objects' was not an issue building wxwidgets 3.0.x)

Did you already use mold for 3.0? Considering how new mold is, I'd have thought you still used GNU ld or maybe lld for it.

At Chromebrew we are using mold for all of our packages, except where it fails. It very rarely fails.

(Wxwidgets 3.1 also appears to build just fine with mold.)
I'd note that we are using the autotools/configure/make build setup for wxwidgets 3.0 and 3.1, whereas we are using cmake for 3.2.x...

This is a cmake build issue. We're using cmake 3.26.0.
It builds fine using:
./configure --prefix=/usr/local --libdir=/usr/local/lib64 --mandir=/usr/local/share/man --build=x86_64-cros-linux-gnu --host=x86_64-cros-linux-gnu --target=x86_64-cros-linux-gnu --program-prefix='' --program-suffix='' \
--with-gtk=3 \
--with-opengl \
--enable-unicode \
--enable-graphics_ctx \
--enable-mediactrl \
--enable-webview \
--with-regex=builtin \
--with-libpng=builtin \
--with-libjpeg=sys \
--with-libtiff=sys \
--without-gnomevfs \
--disable-universal \

I tried building wx3.2.2.1 on Ubuntu 22.10 x64 with default packages (cmake 3.24.2, gcc 12.2.0, mold 1.4.2) and it builds and links fine.
I used:
cmake -G Ninja -DCMAKE_C_FLAGS="-O2 -pipe -ffat-lto-objects -fPIC -fuse-ld=mold -flto=auto" -DCMAKE_CXX_FLAGS="-O2 -pipe -ffat-lto-objects -fPIC -fuse-ld=mold -flto=auto" -DCMAKE_EXE_LINKER_FLAGS="-flto=auto" -DCMAKE_SHARED_LINKER_FLAGS="-flto=auto" -DCMAKE_STATIC_LINKER_FLAGS="-flto=auto" -DCMAKE_MODULE_LINKER_FLAGS="-flto=auto" -DCMAKE_INTERPROCEDURAL_OPTIMIZATION=TRUE -DCMAKE_BUILD_TYPE="Release" ../wxWidgets/
cmake --build . --target wxrc -- -j4
You think it is CMake 3.26 specific?

Well, the previous version is cmake 3.25.3... I can also try with that version...

Sorry, I don't understand: your configure command doesn't seem to use neither LTO nor mold at all, so it doesn't test the same thing?
Could you please check the full link command used by CMake (I admit I don't see how to do it without searching, but it should be possible) and compare it with the link command used when using configure+make?

I've gotten this to build with some tweaks to the build config and using cmake 2.25.3, so I'm going to close this as this looks like an issue with either a newer version of cmake or our build options. Sorry to bother you!

Glad to hear that this was fixed, but it would be still nice to know what exactly did you do in order to fix it, just in case anybody else runs into the same issue and finds this bug report by searching the web.

Switching from mold to gold fixed the build... I will open a ticket upstream with mold...
