Hi everyone, I have some problems with building swift compiler first i cloned the repo ```swift git clone https://github.com/ziad-ashraf7/swift.git cd swift ``` and then ran this command to install the dependencies ```swift utils/update-checkout --clone-with-ssh ``` after that i ran this command to build the project ```swift utils/build-script \ --release \ --debug-swift -j6 ``` and after a while i got some error (and after getting these error the build is still continuing) ```swift prefix/lib/libdispatch.so" to "$ORIGIN" [1505/1688][89%][1923.545s] Linking CXX executable bin/swift-refactor FAILED: bin/swift-refactor .... /home/ziad/GSoC/Swift/swift/lib/ASTGen/Sources/ASTGen/StableHasher.swift:291: error: undefined reference to '$sSlss16IndexingIteratorVyxG0B0RtzrlE04makeB0ACyFSnySiG_Tg5' /home/ziad/GSoC/Swift/swift/lib/ASTGen/Sources/ASTGen/StableHasher.swift:291: error: undefined reference to '$ss16IndexingIteratorV4next7ElementQzSgyFSnySiG_Tg5' /home/ziad/GSoC/Swift/swift-experimental-string-processing/Sources/_RegexParser/Regex/Printing/DumpAST.swift:61: error: undefined reference to '$sSa5countSivgSS_Tg5' /home/ziad/GSoC/Swift/swift-experimental-string-processing/Sources/_RegexParser/Regex/Printing/DumpAST.swift:62: error: undefined reference to '$sSayxSicigSS_Tg5' clang++: error: linker command failed with exit code 1 (use -v to see invocation) [1506/1688][89%][1923.766s] Linking CXX executable bin/swift-ast-script FAILED: bin/swift-ast-script ..... /home/ziad/GSoC/Swift/swift/lib/ASTGen/Sources/ASTGen/StableHasher.swift:291: error: undefined reference to '$sSlss16IndexingIteratorVyxG0B0RtzrlE04makeB0ACyFSnySiG_Tg5' /home/ziad/GSoC/Swift/swift/lib/ASTGen/Sources/ASTGen/StableHasher.swift:291: error: undefined reference to '$ss16IndexingIteratorV4next7ElementQzSgyFSnySiG_Tg5' /home/ziad/GSoC/Swift/swift-experimental-string-processing/Sources/_RegexParser/Regex/Printing/DumpAST.swift:61: error: undefined reference to '$sSa5countSivgSS_Tg5' /home/ziad/GSoC/Swift/swift-experimental-string-processing/Sources/_RegexParser/Regex/Printing/DumpAST.swift:62: error: undefined reference to '$sSayxSicigSS_Tg5' clang++: error: linker command failed with exit code 1 (use -v to see invocation) ``` after getting these logs and errors , the build is not interrupted yet. then at the end of it I got this last error ```swift [#StrictMemorySafety]: ninja: build stopped: subcommand failed.

Any reason you are using `--debug-swift`? That flag is not tested much and [has had regressions](https://forums.swift.org/t/debug-swift-build-fails/71380) over the years. Unless you're really sure you need it for your work to have a Swift compiler frontend built in debug mode, you may be better off building with `--release-debuginfo` or one of the other build options to start off with. ---

Ok, so I believe the linker errors might be due to insufficient RAM on your system. That’s my guess, as I ran into the [same issue](https://forums.swift.org/t/help-request-wsl-docker-build-errors/74140/7) when building with WSL on a machine with only 16GB. After switching to a Mac with 32GB, the debug build compiled without linker errors. ---

That I do not recall, I do have a snippet of one of the linker errors from trying to debug the issue with someone in the past. The snippet did not include the undefined reference now that I look at it (sharing as an image to avoid the horizontal scroll) ![image](https://global.discourse-cdn.com/swift/original/3X/c/6/c61a7f3cc4915149372ee7701af7a4b5ea95dfaa.png) @Ashraf If you haven't already checked this out, The [getting started guide](https://github.com/swiftlang/swift/blob/main/docs/HowToGuides/GettingStarted.md#system-requirements) explicitly states RAM requirements for different machines.

@janjan , I checked the RAM requirements and I have 16GB RAM on my machine. the only mismatch is that I'm trying to build the repo on Manjaro Linux not macOS, Ubuntu Linux as the OS requirements says: "Operating system: The supported operating systems for developing the Swift toolchain are: macOS, Ubuntu Linux LTS, and the latest Ubuntu Linux release. At the moment, Windows is not supported as a host development operating system." so do you think that i should make a swap file to make it help the RAM and avoid the out of memory error? Or the problem is that i use different OS from the supported ones. ---

So do you think if I should change the OS to Ubuntu that i should work on it natively or i can use it with Docker? they already have some Dockerfiles for Ubuntu. I'll try the swap file to give some help to the RAM, and if its not working I'll try the OS option. ---

I highly doubt it is the OS, if you got this far. People build the compiler and full toolchain on everything from BSD to Gentoo to Android, albeit likely without `--debug-swift` mostly. I'd try first without that flag, then only add it later if you need it. ---

Hmm, this isn't even getting as far as the previous flag: did you also update the source in the interim? I would stick with the latest trunk snapshot tag, currently swift-DEVELOPMENT-SNAPSHOT-2025-03-17-a, and not touch that source while you're trying various build flags. What prebuilt host Swift compiler version are you building with? Does it have a `/usr/lib/swift/shims/Visibility.h`? The build appears to be looking there and doesn't find it. ---

@Finagolfin I think that the problem with the path , the Visability.h file is on this path ![image](https://global.discourse-cdn.com/swift/original/3X/1/e/1e2e019db2136d3d5e68276b7067293eabeb711a.png) Not `/usr/lib/swift/shims/Visibility.h` . what do you think could be the reason for this ? i just installed `Swift` from the AUR package ```swift paru -S swift-bin ``` ---

The reason people use —debug-swift is because we tell them so in the GettingStarted.md.(docs/HowToGuides/GettingStarted.md). It even promises a fruitful debugging experience. I see two ways to get around this: Option 1: Keep —debug-swift stable Option 2: Remove —debug-swift from the guide. What do you think about this? @Finagolfin ---

> [@Ashraf](#): > > what do you think could be the reason for this ? Not sure, but that seems an incorrect install, whether because of AUR itself or the way your distro is using it. You can compare the file layout in [one of the official prebuilt toolchains for linux](https://www.swift.org/install/linux/) to see what it should be. If one of those runs on Manjaro, I recommend you use it instead for your host toolchain: just add it to your `PATH` and the trunk compiler build will pick it up. > [@xavgru](#): > > What do you think about this? @Finagolfin I don't think I've used that flag in years myself, so no real opinion. It should probably have a sporadic CI that somebody looks at for these regressions, if that's what the problem is. ---
