example ppx rewriter not compatible with dune "No ppx driver were found" error #102

Closed aryx closed 4 years ago

aryx commented 4 years ago

I've tried to use the examples in examples/omp_ppx_here/ to build my own ppx rewriter. However after a make install in this directory, I tried to use the ppx in one of my project using dune with (preprocess (pps omp_ppx_here))

but then I got the following error: ile "matching/dune", line 4, characters 13-31: 4 | (preprocess (pps omp_ppx_here)) ^^^^^^^^^^^^^^^^^^ Error: No ppx driver were found. It seems that omp_ppx_here is not compatible with Dune. Examples of ppx rewriters that are compatible with Dune are ones using ocaml-migrate-parsetree, ppxlib or ppx_driver. Makefile:3: recipe for target 'all' failed

What do I need to get omp_ppx_here usable from dune?

Hmm, these examples are quite old. We could port them to Dune, though we are preparing a 2.0.0 release of ocaml-migrate-parsetree that will drop the driver part. You should use ppxlib for new ppx rewriters.

Ok, thx!
