Deadlock when loading World of Warcraft ARM64 EXE: "loader_section" wait timed out

[SwimmingTiger]

Some ARM64 platforms have a powerful enough SoC and have an ATX motherboard that can accommodate regular PCI-E graphics cards. That's enough for a challenge to run World of Warcraft ARM64 edition.

So I built an ARM64 version of wine to try and run it:

Code: Select all

export CC=clang CXX=clang++ PATH=/path/to/clang-13/bin:$PATH LD_LIBRARY_PATH=/path/to/clang-13/lib
cd wine
./configure
make -j$(nproc)
make install -j$(nproc)

Code: Select all

/path/to/wine-devel-7.5-arm64/bin/wine Wow-ARM64.exe -d3d11

However I only get deadlocks:

Code: Select all

0748:err:sync:RtlpWaitForCriticalSection section 000000007BC7B438 "dlls/ntdll/loader.c: loader_section" wait timed out in thread 0748, blocked by 0744, retrying (60 sec)

Tried WINEDEBUG=+all then I got this:

The Wine binary I built: https://file.winegame.net/runners/wine/ ... m64.tar.xz

It's an ARM64+x86 mixed installation. At first I built a pure ARM64 wine, but I quickly found out that the WoW ARM64 edition has some additional x86 exe, so I built this hybrid.

I run box86 for x86 emulation, so this hybrid install works just fine on x86 games (like Warcraft III). It's even smoother than pure x86 wine (probably because wineserver etc have ARM64 native binaries).

However, ARM64 native games like World of Warcraft do not work. The same deadlock applies whether it is a pure ARM64 wine installation or a mixed ARM64+x86 wine installation. It looks like the execution of Wow-ARM64.exe has not reached its x86 add-on at all. The execution of the EXE enters a deadlock in the early stages of loading.

Any debugging or fix comments are welcome. I have C programming experience, but I am not familiar with the wine project.

For someone who wants to test it themselves: if you don't have an ARM64 Windows installation, you can extract Wow-ARM64.exe via CASCExplorer in x86_64 Windows.

All branches of World of Warcraft (Retail, Burning Crusade Classic and Classic Era) have native ARM64 executables.
