Per-package extra-include-dirs/extra-lib-dirs

[Adam Bergmark]

Hi,

I'm struck by https://github.com/phonohawk/HsOpenSSL/issues/41 where one solution is to specify extra-include-dirs and extra-lib-dirs to use when compiling HsOpenSSL. 

One way is to add these to the stack.yaml's of all projects that use HsOpenSSL along with  ~/.stack/global-project/stack.yaml. This could be added to the stack.yaml template but for shared stack.yaml's this is cruft for non-OS X users.

Another way is to set this globally in ~/.stack/config.yaml. The disadvantage here is that this flag is set for local packages *and* extra-deps, so when building unrelated things I get recompiles along these lines: "haskell-src-exts-1.18.2: unregistering (flags changed from [] to ["--extra-include-dirs=/usr/local/opt/openssl/include","--extra-lib-dirs=/usr/local/opt/openssl/lib"])".

Optimally I would be able to specify this globally in ~/.stack/config.yaml but only have it apply to HsOpenSSL.

As far as I can see this is not possible at the moment. Has it been discussed? Do you think it's a good idea?

Regards,

Adam

Hi Adam!

Thanks for emailing the list, I am currently processing my big backlog of email.  I've turned this into a stack issue: https://github.com/commercialhaskell/stack/issues/2626  What do you think of that approach?

That looks exactly like what I need, thanks Michael!
