| 2026-03-23 10:59:04 | <Freakie> | no, seems I'm back where I started :/ the library files don't inclued dependencies |

| 2026-03-23 11:00:37 | <[exa]> | Freakie: the "dependencies" are what exactly, in this case? (other haskell libraries?) |
| 2026-03-23 11:03:03 | × | husixu quits (~husixu@2406:3003:2007:fe4:68ee:9c53:6141:39ea) (Quit: Leaving) |
| 2026-03-23 11:03:19 | <Freakie> | i'll get back to you in 15 minutes |

| 2026-03-23 11:14:53 | <Freakie> | the dependencies are just package imports from cabal |
| 2026-03-23 11:15:39 | <Freakie> | including ones maintained by the haskell org directly such as containers |
| 2026-03-23 11:16:27 | <[exa]> | I'm still confused |
| 2026-03-23 11:16:34 | <[exa]> | what command do you write there then? |
| 2026-03-23 11:17:04 | <[exa]> | I assumed something like `gcc something.cpp -lmyhaskellib -lcontainers -Lsomewhere/deep/in/dist-newstyle/blah/bleh/containers/lib ....` |
| 2026-03-23 11:17:29 | × | merijn quits (~merijn@host-cl.cgnat-g.v4.dfn.nl) (Ping timeout: 248 seconds) |
| 2026-03-23 11:17:54 | <Freakie> | well that's the thing |
| 2026-03-23 11:18:04 | <Freakie> | the lib files are located wherever cabal installed them |
| 2026-03-23 11:18:17 | <Freakie> | which is hell to keep track of |
| 2026-03-23 11:18:46 | <Freakie> | one of the imports has 4 or so directories that each have a lib file for that package and I don't know which of those 4 is the one cabal uses |
| 2026-03-23 11:19:03 | <[exa]> | what happens if you reverse the logic, put the cpp main() in a cabal project and just call it as the first thing from haskell main and let it do its own thing? (I assume that would push cabal to link it correctly by itself) |
| 2026-03-23 11:19:25 | <Freakie> | will try |
| 2026-03-23 11:19:41 | × | Enrico63 quits (~Enrico63@host-79-18-154-39.retail.telecomitalia.it) (Quit: Client closed) |
| 2026-03-23 11:20:08 | <[exa]> | btw might be helpful to wait for evening until more people wake up, I did this only in a remotely similar fashion, 2 times probably, and ended up working it around in both cases |
| 2026-03-23 11:20:51 | <Freakie> | maybe, but as long as someone more informed than myself is around I can get nudged in the right direction |
| 2026-03-23 11:21:21 | <Freakie> | also might be more prudent to save some energy for advice regarding why my program still uses 100x more memory than it should, if you recall me praying to the gods about that |
| 2026-03-23 11:21:27 | <[exa]> | yeah, I meant, more such people would appear later today |
| 2026-03-23 11:21:59 | <[exa]> | Freakie: is the 100x more like 1kB and 100kB or more like 1GB and 100GB? |
| 2026-03-23 11:22:27 | <Freakie> | to give you an idea: for the smallest input sizes memory usage is the nursery size, more or less |
| 2026-03-23 11:22:40 | × | arandombit quits (~arandombi@user/arandombit) (Ping timeout: 245 seconds) |
| 2026-03-23 11:22:42 | <Freakie> | then it jumps from 6 mb, to 14, to 130, to 1-2 gb, to more than I have ram |
| 2026-03-23 11:23:12 | <[exa]> | you might need a spraybottle of strictness annotations |
| 2026-03-23 11:23:12 | <Freakie> | I tried using GHC.DataSize which has the size effect of doing garbage collection, but not the same way that System.Mem does |
| 2026-03-23 11:24:16 | <[exa]> | if you have any data that you expect to be actually stored for some time (not just stream through some functions and disappear completely), add a lot of ! into them |
