[Build] Stack build error

Error: [S-7282]
       Stack failed to execute the build plan.

       While executing the build plan, Stack encountered the error:

       [S-7011]
       While building package duckling-0.2.0.0 (scroll up to its section to see the error) using:
       /home/hyunsoo/.stack/setup-exe-cache/x86_64-linux/Cabal-simple_6HauvNHV_3.0.1.0_ghc-8.8.4 --verbose=1 --builddir=.stack-work/dist/x86_64-linux/ghc-8.8.4 build lib:duckling exe:custom

       Process exited with code: ExitFailure 1

I installed the required packages through sudo apt-get install libpcre3 libpcre3-dev before the build. Once installed, stack build displays compile error without helpful failure information. Anybody can help?

OS: Ubuntu 24.04 LTS x86_64

I had the same problem, it seems some of the recent commits to this project caused this problem, you must download the last stable version from releases (v0.2.0.0) if you want to work with this project.

cc @patapizza - I'm guessing you may be able to work out where the problem is most quickly

Thanks @abolfazlakbary, I installed with v0.2.0.0 again and build passed.

A new error is found when I execute a binary. Did you not encounter this kind of error?

❯ stack exec duckling-example-exe
duckling-example-exe: /etc/zoneinfo/: getDirectoryContents:openDirStream: does not exist (No such file or directory)

Actually @hyunsooda , i had the same error . if your operating system is linux, you must edit a file in project_dir/exe/ExampleMain.hs. search for a function called loadTZs, and as you can see two variables are defined, defaultPath and fallbackPath. I solved the issue by giving both variables this value: "/usr/share/zoneinfo/".

@abolfazlakbary Thank you for your support. I used your guidance to make adjustments and recompiled the project. However, I encountered an OlsonData library error. It might be worth it for the team to verify and reorganize the build environment and executable setup.
