build error

[vikas sharma]

I am trying to install `libsigsegv` on 

arch=linux-ubuntu22.04-ivybridge

from source. 

Steps to reproduce the error:

```

tar zxpf libsigsegv-2.14.tar.gz

cd libsigsegv-2.14

 ./configure --enable-shared --prefix="/home/easifem/temp/"

make

``` 

The following error is reported:

```

```

In the `.libs` directory, I have:

```

Why there is no `libsigsegv.so.2.0.7`? 

Thanks in advance
