Does not build on Arch Linux

[melody-notpond]

On Arch Linux, trying to run ./build.sh yields the following error:

'CGLib' glib-2.0 gio-unix-2.0.pc: warning: couldn't find pc file
'CCairo' cairo glib-2.0 gio-unix-2.0.pc: warning: couldn't find pc file
fish: “./build.sh” terminated by signal SIGSEGV (Address boundary error)

I believe I have all required packages installed, but what's puzzling is the address boundary error. 🤔

[mikolasstuchlik]

There is an issue in the current Package.swift files of the SwiftGtk project and it’s dependencies. It is explained in “ Building the project using swift build” section of #34.

It’s only guess but there might be an issue related to SPM.

The build.sh script forwards any following arguments to swift build command, appending -v flag might provide us with more information. ($ ./build.sh -v)

And/Or you can try following:

I have already implemented the pitch in my forks, so you can try, whether the changes I made to the build process solve the issue for you. I have created a demo project for purposes of the PRs I have opened, you can find it here: https://github.com/mikolasstuchlik/Matika.

Here is the result of ./build.sh -v:

I'm currently trying to build your fork; I'll let you know the results when it's done.

[melody-notpond]

I attempted to build your fork and unfortunately it did not work. :(
Here is the output of swift build -v:

[mikolasstuchlik]

This looks like an issue with the Swift Package Manager to me, rather than an issue with the SwiftGtk itself (=> it might be an issue for the Swift Forum).

If there is an issue with the SPM, there is probably nothing I can do for you :(

If the problem is unrelated to the SwiftGtk, I think that attempt to compile only .systemLibrary module importing "gio-unix-2.0" should fail aswell. I have created such project when resolving an issue with LLDB. You can find it here https://github.com/mikolasstuchlik/LldbMinimalTest

It is quite a simple Swift package, it does nothing. There are three modules, CGLib which uses pkg-config to import "gio-unix-2.0", GLib which adds some settings important for the debugger and LldbMinimalTest which is an executable module.
The package should build successfuly (I have just tired it on my Ubuntu 20.04). In case it does not, this might be indeed a SPM issue.

Edit: I get the "non-whitelisted" warning too.

mikolas@MIKI-U-NTBK:~/FI-Developer/apps/LldbMinimalTest$ swift package clean

mikolas@MIKI-U-NTBK:~/FI-Developer/apps/LldbMinimalTest$ 

[melody-notpond]

I can build LldbMinimalTest successfully. Strange. Does this mean it's not a problem with the Swift package manager?

[mikolasstuchlik]

Well, I would say that there is an issue with SPM, since build should not ever end by SIGSEGV.

The question what triggers the issue (and whether there is a workaround) remains. Would you tell me what version of Arch and Swift toolchain are you using, please? I might have some time to look at the issue myself in following days.

Build the latest SPM from https://github.com/apple/swift-package-manager and use it to build. This is a bug in SPM that I fixed in main

[melody-notpond]

Okay so i built the latest SPM from the github repo provided and I got the following error when building with the new SPM:

/home/jenra/SwiftGtk: error: manifest parse error(s):
/home/jenra/SwiftGtk/Package.swift:3:8: error: no such module 'PackageDescription'

       ^

[Dadoum]

Did you install SPM in the folder of your swift toolchain ? And can you try to build an example project using swift run ?

[melody-notpond]

I made an example project with swift-package init and got the same error:

@Dadoum (@jenra-uwu)

Hello. First of all - I am not a "linux power user", so excuse my lack of linux proficiency. I have tried to look into the issue myself and I will probably need some guidance. I will desribe all steps I took.

[I'm using VBox 6.1 from Ubuntu 20.04]

I have:

• downloaded manjaro xfce 20.0.1-210103 and installed it into my VBox VM
• installed yay sudo pacman -S yay
• installed swift-bin prerequisitied sudo pacman -S patchelf and sudo pacman -S rpmextract
• installed devel packages sudo pacman -S base-devel with no option (default = all)
• installed swift using yay yay -S swift-bin which installed Swift 5.3.1
• cloned https://github.com/apple/swift-package-manager and https://github.com/rhx/SwiftHelloGtk
• installed jq yay -S jq
• in repo SwiftHelloGtk generated files by using ./run-gir2swift.sh
• attempted to build using swift build with the same result as @jenra-uwu

Then I tried to build and "install" swiftPM where my lack of knowledge hit me so I was unable to "install SPM in the folder of my swift toolchain". I have made following steps:

• entered the swift-package-manager folder and build the SPM using swift build
• copied file swift-build into the toolchain folder sudo cp .build/debug/swift-build /usr/lib/swift/bin/swift-build-new (Edit: in a previous attempt, I have just replaced all files by the SPM build)
• attempted to build SwiftHelloGtk again using /usr/lib/swift/bin/swift-build-new with the same result as with the regular swift build

Then I have started to think about the issue. My lack of understanding "how to install the SPM" lead me to consider, whether I have in fact replaced the SPM since build products also contain libSwiftPM.so and other libraries. I have found no such libraries in the toolchain, also the size of swift-build is around 60M so it migh contain more than just one line of code (as written in the target).

I have also searched Github for any PR opened by you on SPM (swiftlang/swift-package-manager#3080). I have checked again and there is no package with more than one package in pkgConfig since the version 12 (of the gir2swift) was released.

Since you mentioned in the PR, that the PR resolves the https://bugs.swift.org/browse/SR-13424, I think that the issue is on my side due to being unable to "install the SPM" correcly.

Would you please help me to do so? :)
Thanks -stuchlej

Edit2: I need to go now, but I figured out it might be useful to post a stack trace (i needed to rebuild spm with searialize debugging option enabled). I'll look in to this soon but for now I need to go afk. I'll be in touch.

The manual way is to get CentOS toolchain from trunk development on swift.org here and to patch it to replace every needed libraries with this command (to run in extracted toolchain folder):

find . -executable -type f -exec patchelf --replace-needed libncurses.so.6 libncursesw.so --replace-needed libpanel.so.6 libpanelw.so --replace-needed libform.so.6 libformw.so {} \;

The fast way is to clone swift-bin AUR package and replace in the PKGBUILD the source URL with the URL of trunk development and checksum with SKIP (I did not test, but should work)

use this PKGBUILD:

# Maintainer: Ryan Gonzalez <rymg19 at gmail dot com>

      -not -name '*.py' \
      "$@"
  }

  mkdir -p "${pkgdir}/usr/lib/swift"
  cp -Ppr "${srcdir}/swift-DEVELOPMENT-SNAPSHOT-2021-01-15-a-centos8"/usr/* "${pkgdir}/usr/lib/swift"

  # Symlink the desired binaries to /usr/bin
  mkdir -p "${pkgdir}/usr/bin"
  for bin in sourcekit-lsp swift swiftc; do
    ln -s "/usr/lib/swift/bin/$bin" "${pkgdir}/usr/bin/$bin"
  done

  # Patch the binaries to use the changed ncurses names
  patchelf=(patchelf)
  for lib in ncurses panel form; do
    patchelf+=(--replace-needed "lib${lib}.so.6" "lib${lib}w.so")
  done
  find_elf_only -exec "${patchelf[@]}" {} \;

  install -dm755 "${pkgdir}/etc/ld.so.conf.d"
  echo '/usr/lib/swift/lib/swift/linux' >> "${pkgdir}/etc/ld.so.conf.d/swift.conf"
}

PS: With "yay" AUR helper, the PKGBUILD is located in ~/.cache/yay/swift-bin/PKGBUILD, and install it then with makepkg -si in the folder

[melody-notpond]

I was able to successfully install this version of Swift, but the build process still terminates with a SIGSEGV. I built this using the modified PKGBUILD you provided to install Swift. Below is my output:

[mikolasstuchlik]

@Dadoum Thanks for your reply. I will describe all steps in the list below:

I have:

• Removed current swift-bin by executing yay -R swift
• Deleted folder /usr/lib/swift and almost all content of ~/.cache/yay/swift-bin/
• (At this point I run out of disk space on my VM so I had to delete a lot of files :) )
• I have copied current PKGBUILD cp ~/.cache/yay/swift-bin/PKGBUILD ~/.cache/yay/swift-bin/PKGBUILD.old and replaced the contents of original file by the PKGBUILD file you have posted
• Run makepkg -si
• Entered the SwiftHelloGtk project folder and experienced the same issue
