Hello,

I’m trying to reinstall FreeFem++ v4.7 in a new computer (MacOs version 10.15.7).

At the step ` make petsc-slepc` , it gives me this error message:

```
> *******************************************************************************
> UNABLE to CONFIGURE with GIVEN OPTIONS (see configure.log for details):
> -------------------------------------------------------------------------------
> Error running make on SCALAPACK
> *******************************************************************************
> 
> make: *** [petsc-3.13.5/tag-conf-real] Error 1 

```

With [configure.log](https://community.freefem.org/uploads/short-url/qek6Pbd2aEf1fg4LN147fcaRMTo.log) (1.3 MB)

And i can’t solve this problem. Could someone please help me?

Thank you !

Why do you need to re-open a post? [Problem when compiling SCALAPACK](https://community.freefem.org/t/problem-when-compiling-scalapack/587/17)  
This is fixed in the `develop` branch, as answered in the original post (branch `petsc-3.14.0` has been merged in `develop` since then).

when I do  
` git clone -b petsc-3.14.0 https://github.com/FreeFem/FreeFem-sources`  
it says  
`fatal: La branche distante petsc-3.14.0 n'a pas été trouvée dans le dépôt amont origin`

It works now from the develop branch.
