@JeffreyBenjaminBrown the `libstdc++6` package only provides the bare library, without the files needed for compile-time linkage; I'd suggest to `apt install g++` as that will iirc result in a minimal...

That's strange; can you create a file `hello.cc` somewhere with the content below, and then compile&link that via `g++ hello.cc -o hello` and see if that results in an executable...

Fwiw, the current pragmatic `||`-style constraint were a stop-gap solution towards the proper solution that #3502 aims to (I wasn't able to quickly locate the more specific issue/commit that got...

sure, that'd be an incremental improvement within the current inadequate constraint-language; but I was trying to point out that we have a far bigger problem at hand... you'd just be...

It appears the same problem exists with global `flags` not being honored

Btw, here's a quite common use-case I heard from an OSX user w/ homebrew: ``` package HsOpenSSL extra-lib-dirs: /usr/local/Cellar/openssl/1.0.2h_1/lib extra-include-dirs: /usr/local/Cellar/openssl/1.0.2h_1/include ```

@peti btw, one problem I recently realised is that such a global setting would force *every* package, including GHC boot libraries to be recompiled, as it would force a new...

@peti Personally, I think that'd quite reasonable to have in ~/.cabal/config (or nearby). I do wonder though how to be able to locally override the global setting. Especially with openssl,...
