[solved] llvm & clang - how to combine multiple svn sources

Hi,

recently i created the aur package llvm-amdgpu-svn and am now looking into adding the svn clang, clang-analyzer and llvm-ocaml code also.
Since compiling clang requires the llvm source code to be present, it makes sense to use  a split package for this, like the official llvm package.

This page has the build instructions for clang  : http://clang.llvm.org/get_started.html

In short i need to do 4 svn checkouts, and 3 of them have to be in a specific directory.
All 4 checkouts share the same revision number.

I'd like to stick with the code in the svn prototype pkgbuild, but don't know how to adapt that to do 4 checkouts.

  if [[ -d "$_svnmod/.svn" ]]; then
    (cd "$_svnmod" && svn up -r "$pkgver")
  else
    svn co "$_svntrunk" --config-dir ./ -r "$pkgver" "$_svnmod"
  fi

The main problem i have is whether i can use the 'svn up' part for all 4 checkouts.
Or should i just wait until pacman 4.1 is released and use it's new method for VCS sources ?

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: [solved] llvm & clang - how to combine multiple svn sources

Turns out it was simpler then i thought, this is what i'm using now :

  cd "$srcdir"
  msg "Connecting to llvm SVN server...."

  if [[ -d "$_svnmod/.svn" ]]; then
    (cd "$_svnmod" && svn up -r "$pkgver")
  else
    svn co "$_svntrunk" --config-dir ./ -r "$pkgver" "$_svnmod"
  fi

# clang 
  msg "downloading clang"
  if [[ -d "$_svncfemod/.svn" ]]; then
    (cd "$_svncfemod" && svn up -r "$pkgver")
  else
    svn co "$_svncfetrunk" --config-dir ./ -r "$pkgver" "$_svncfemod"
  fi

# compiler rt
  msg "downloading compiler-rt"
  if [[ -d "$_svncrtmod/.svn" ]]; then
    (cd "$_svncrtmod" && svn up -r "$pkgver")
  else
    svn co "$_svncrttrunk" --config-dir ./ -r "$pkgver" "$_svncrtmod"
  fi
  
  msg "SVN checkout done or server timeout"
  msg "Starting build..."

  rm -rf "$srcdir/$_svnmod-build"
  msg "copying llvm"
  svn export "$srcdir/$_svnmod" "$srcdir/$_svnmod-build"
  msg "copying clang"
  svn export "$srcdir/$_svncfemod" "$srcdir/$_svnmod-build/tools/clang"
  msg "copying compiler-rt"
  svn export "$srcdir/$_svncrtmod" "$srcdir/$_svnmod-build/projects/compiler-rt"

Using the correct vars and giving them the correct value was the hardest part.

Now it's onwards to creating the rest of the PKGBUILD.
