Lahey Computer Systems will permanently close on
December 31, 2022
Effective December 31, 2022, Lahey Computer Systems, Inc. will no longer license Fortran language systems.

Lahey regrets we can no longer maintain the standards necessary to support your business.

We appreciate that you selected Lahey to provide your Fortran language systems and services for the past 55 years.

Thank you,
Thomas M Lahey
CEO

I learnt Fortran (back in 2009) by reading Lahey’s Fortran 90 book.

My favorite compiler at my first job was Lahey’s. It provided the clearest error messages (at least from the compilers I had access to at the time). Sad that it is officially discontinued.

Tom, thanks for all the work and support you and Lahey have given to the entire Fortran community over the years. We’ll miss Lahey, truly a great compiler, a great company, and you are a true gentleman. Thank you.

I still have some working version, twenty years old:

R.I.P.

Are they in a position to open source their Fortran compiler if they will not be in the Fortran compiler business anymore?

That would be awesome if they could do that.

Great point @certik.

@RonShepard expressed the same thought in a related discussion at comp.lang.fortran with the other one also, Absoft Fortran compiler.

Perhaps this can be Google Summer of Code project next year to establish open source repositories for both Absoft and Lahey Fortran compilers if the legwork can be completed now by this Community to reach out to surviving communication channels for Absoft Inc. and Lahey Inc. and influence them to not make their great products as abandonware but rather that they can have their outstanding legacy live on as open source efforts!
