[GitHub] [incubator-nuttx] btashton opened a new issue #2099: qemu-i486 build broken
btashton opened a new issue #2099:
URL: https://github.com/apache/incubator-nuttx/issues/2099
The `qemu-i486:nsh` and `qemu-i486:ostest` configurations do not seem to build any more due to a linker error looking for `libm`
```

Ok looks like I was wrong here and it is intentional. Including the `glibc-static.i686` fixes this, I did not even have the 64-bit version on my system, for the x86_64 port we have `LIBM=y` so this is not required.

@btashton
Oh really?
I can build qemu-i486:nsh and qemu-i486:ostest on ubuntu18.04 x86_64.
```
make V=1

Do we really want to be using the system math library here? That seems wrong to me.

I'll try building it again with verbose logs, but it did not work correctly for me in either config.
