@yataro, yeah thank you very much for the suggestion

@ggnoredo hashsums are fine, I advise you to do a clean build, maybe source archive got corrupted because of network issues (dotnet/runtime archive is pretty heavy).

Yeah, CMake 4.0 landed a few days ago. Thanks for the fix

I'm getting the following error building:

I've added -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to the PKGBUILD and it then worked.

Builds just fine, though I did face the following error:

error NU1101: Unable to find package Microsoft.NETCore.App.Host.arch-x64

I found this forum post which seemed to be facing a similar, if not the exact same issue: https://bbs.archlinux.org/viewtopic.php?id=265923 I decided to just remove all dotnet packages (as I had installed more than I was actually using for some reason) and go through the installer which installed the latest ones back. Worked like a charm! :3

Fails to build.

 -> Failed to install the following packages. Manual intervention is required:
netcoredbg - exit status 4

I was able to build the package with the following PKGBUILD:

pkgname=netcoredbg
pkgver=1.2.0
githubrel=786
pkgrel=1
pkgdesc='Debugger for .NET Core runtime'
url='https://github.com/Samsung/netcoredbg'
license=(MIT)
arch=(x86_64)
depends=(dotnet-host dotnet-runtime dotnet-sdk)
makedepends=(git cmake ninja clang)
optdepends=()
source=("${url}/archive/refs/tags/${pkgver}-${githubrel}.tar.gz")
sha256sums=('818c2df57f3f691d758829c22f532eb96212c63cd9504b4843eb068ee655c2da')

prepare() {
  cd "${srcdir}/${pkgname}-${pkgver}-${githubrel}"
  mkdir -p "${srcdir}/build"
}

build() {
  cd "${srcdir}/build"
  CC=clang CXX=clang++ \
  cmake "${srcdir}/netcoredbg-${pkgver}-${githubrel}" \
     -GNinja \
     -DDOTNET_DIR=/usr/share/dotnet \
     -DCMAKE_INSTALL_PREFIX=/usr/share/dotnet
  ninja
}

package() {
  cd build
  DESTDIR="$pkgdir" ninja install
  mkdir -p "${pkgdir}/usr/bin"
  ln -s /usr/share/dotnet/netcoredbg "${pkgdir}/usr/bin/netcoredbg"
}

There is still a lot of testing to do

This package is failing due to the URL "https://github.com/Samsung/netcoredbg/archive/latest.tar.gz" yielding a 404, as well as the "fix.patch" breaking the build for some reason.

I was able to build it by modifying the PKGBUILD to explicitly download and build the 1.2.0-738.tar.gz archive and comment out the step where it patches the source code.

After installing it worked just fine on the open source release of VS Code from the Arch community repo, following the instructions on the wiki.

I believe this should be updated to remove the patching step (why is it needed?) and find some other way to fetch the latest release, properly maintain it or just fetch from git directly, because the program works just fine otherwise.
