Cannot install async_io op even if it's compatible flag is displaying OK by ds_report cmd!

When i use DS_BUILD_AIO=1 CFLAGS="-I$CONDA_PREFIX/include/ -I/usr/include/" LDFLAGS="-L$CONDA_PREFIX/lib/ -L/usr/lib/x86_64-linux-gnu/" pip install -e . to install async_io op, i get fake successful msg.
it indeed displays Successfully installed deepspeed , but i use ds_report and only get .

And i use print stderr msg and i find that

To figure out how to result in this case's coming. I read the source code such as "setup.py"...
and i find problem in "setup.py line 182"
for op_name, builder in ALL_OPS.items(): op_compatible = builder.is_compatible()
When op_name is "async_io", builder.is_compatible() returns false. And i open the "DeepSpeed/deepspeed/ops/op_builder/async_io.py" and find "line 93" def is_compatible(self, verbose=False) . It's result depends on "line 99" aio_compatible = self.has_function('io_submit', ('aio', )) .
Go on to find def has_function() in "DeepSpeed/deepspeed/ops/op_builder/builder.py line308" , and i confirm it raise linkerror in line362
compiler.link_executable(objs, os.path.join(tempdir, 'a.out'), extra_preargs=self.strip_empty_entries(ldflags), libraries=libraries, library_dirs=library_dirs) by "distutils.unixccompiler.UnixCCompiler"
I don't know why it happened and to address this issue i had to change the "class AsyncIOBuilder"("DeepSpeed/deepspeed/ops/op_builder/async_io.py") like the following picture .

And i install it again and get the correct result.

I hope u can figure out why it caused link error. And i don't know my change whether to cause aio disabled when i use offload.
