I’m trying to use LibSndFile.jl, but I get a following error:

```julia

So I tried to build LibSndFile, but I got more error.

I added Compat, but I got the same error.  
How could I solve this problem?

Can you try using `v2.3.0` of `LibSndFile.jl`?

```julia
]add LibSndFile@v2.3.0

```

As a general remark, try to not put too many package in the global environment and use instead local environments, this will save you from 99% of incompatibilities issues in the future.

For the specific case, it looks like `WORLD` (which I assume is [https://github.com/r9y9/WORLD.jl](https://github.com/r9y9/WORLD.jl) and looks fairly old) is preventing you from installing a more recent FFTW version. Do you need both `WORLD` _and_ `LibSndFile` in the same environment? If not, remove `WORLD` and then you should be able to update `LibSndFile` to the latest version (which shouldn’t have the problem you were experience originally). Even better, keep in the global environment as small as possible and install `LibSndFile` in a local environment

Thank you for your advice! It’s really helpful for me because I’m occasionally in trouble over compatibilities.

Removing `WORLD`，I was able to use l `LibSndFile`. However, I was thinking of using both. Is there no way to use them at the same time?

Not as `WORLD.jl` is now. It needs to be updated. I might have the time to open a pull request this weekend (no promises!), but then the maintainer needs to agree with the changes and merge it

I will be glad if you open a pull request. I hope the maintainer will merge it.
