Hello everyone! It is possible to use stdlib as an fpm package directly? I’m using gfortran under Ubuntu WSL2.

I created a new fpm project and add these lines to the end of the fpm.toml

```auto
[dependencies]
stdlib = { git="https://github.com/fortran-lang/stdlib", branch="stdlib-fpm" }

```

after use fpm build I’m obtaining this error

```auto
# gfortran (for build/gfortran_debug/stdlib/stdlib_linalg_outer_product.o build/gfortran_debug/stdlib/stdlib_linalg_outer_product.mod)
f951: Fatal Error: Module file ‘stdlib_linalg.smod’ has not been generated, either because the module does not contain a MODULE PROCEDURE or there is an error in the module.
compilation terminated.

It looks like you’re using the old Haskell version of fpm. I wouldn’t be surprised if there is some aspect of stdlib that it doesn’t like. I recommend upgrading to a newer, Fortran version of fpm.

There was an issue about this, where we discussed a few of the issues

The best option of course would be to upgrade to a Fortran fpm version.

@everythingfunctional @awvwgk Thanks for your responses! I made this

```auto
$ git clone https://github.com/fortran-lang/fpm.git
$ cd fpm
$ ./install.sh

```

and now seems to work. Is this the correct approach to update fpm?

All the best!

It’s one option. Please check the [README “Getting started” section](https://github.com/fortran-lang/fpm/#getting-started) for other approaches.
