ld error when make whisper.

[MasterJerryZh]

Hello, there are some error occur when I clone latest code and build it. I just use linux cmd "make" to build and install.

My OS version: ubuntu 18.04 g++ version: 7.5.0 boost lib version: 1.74 src version git hash: 6bbe3cd621e50e893fbe7d828e94dc76a6de8aef

The error info:

I have try to build in other two history that Sep 29, 2021 88fdb9c63308ac2cd5e4d977acee5a18848dbc65 and Aug 24, 2021 980353a1f9372da37ddb9f1355875d83d888c6c1, it can passed and there is no error and whipser can be used normally. Could you help me solve my problem? Please.

The build completes cleanly for us using Ubuntu 20.4 and g++ 9.3.0 We will try to figure out the issue.

[MasterJerryZh]

I look forward to your early settlement of this error. Thanks.

[aprnath]

We were able to reproduce the error on Ubuntu 18.04 and gcc 7.4. We will update a fix soon.

[aprnath]

Fix has been pushed.
