[odb-users] Mutex may not be released Re: It was blocked by odb::sqlite::connection_pool_factory::create()

Hi, Boris:
After upgrading to odb2.5.0, this issue has been resolved. Thanks!

Here I have a new question.
How to build arm64 target odb static lib in x64 platform with msvc?
I tried the following script, but it failed.

bpkg create -d libodb-msvc-release cc^
  config.cxx=cl^
  "config.cc.coptions=/std:c++20 /O2 /MD /Zi /arch:armv8.0"^
  "config.cc.loptions=/MACHINE:ARM64"^
  "config.bin.lib=static"^
  config.install.root="%CurrentFolder%output\Release"

Could you help? Thank you in advance.

Sunny Sun

The Win32-based support is still in 2.5.0 and is unchanged (it will be
dropped in 2.6.0 once we drop support for C++98/03). But by default in
2.5.0 we don't use it, instead using the C++11 threading support. This
is controlled with the ODB_THREADS_* macros, for example:

I will again suggest that you try 2.5.0 and see if that makes a
difference.
