Hello all!

Thank you very much for this space.

I found a problem using LsqFit within a module in Julia 1.8.5 installed on Ubuntu 22.04.  
If I create a simple module as as in the following MWE, I got long list of warnings all which indicated:  
` **incremental compilation may be fatally broken for this module** `.

```julia
module A

using LsqFit

end 

```

Here I paste the complete list of warnings:

Could you help me to solve this issue?

Thanks a lot

I can’t reproduce on v1.8.5 or v1.9.0-rc2.

```julia

Thank you for answer me @mbaz.

I have the problem if I save the module in a text file and I try to load it as indicated below:

```julia
push!(LOAD_PATH, "MY_PATH")
using A

```

It just happen the first time that I tried to use the module after saving a change. For example, if I added a comment to the module A:

```julia
module A 
# 
using LsqFit
end 

```

If I create the module inside the Julia REPL and then load it, it does not generates the warnings. I do not understand why.

Thanks again!

I suggest trying with an empty environment. Start with:

```julia
pkg> activate --temp
  Activating new project at `/tmp/jl_WL5BkO`

pkg> st
Status `/tmp/jl_WL5BkO/Project.toml` (empty project)

pkg> add LsqFit
[...]

pkg> st
Status `/tmp/jl_WL5BkO/Project.toml`
  [2fda8390] LsqFit v0.13.0

pkg>

```

and then try using your module again. If it works, then it’s possible there’s an incompatibility between LsqFit and some other package (possibly MPFR.jl).

Thanks again.

I tried and it works. However, reading the warnings I received it seems that incompatibility can be related to StatsFuns in my case.

The warnings indicates: `overwritten in module StatsFuns on the same line (check for duplicate calls to 'include').`

It works for me with just LsqFit and StatsFuns installed. You may need to try installing (in a temporary, clean environment) different combinations of the packages you’re using until you identify those that are incompatible.
