Unable to build on macOS 12.2 Monterey and XCode 13.

[falcon4ever]

Hello,

I tried to pick up last years project but unfortunately it looks like things are broken for the latest macOS/XCode version.

Initially I tried to retrace my steps I had posted here #1 (comment)

I'm still on an Intel Macbook Pro, but there are a few things that have changed:

• Last year I was using macOS Catalina but now I'm using macOS Monterey 12.2 and XCode 13.2.1
• macOS Monterey only supports XCode 13+ afaik, if you try to run XCode 12.x it gives you a warning and suggests you to install a later version.

On a fresh setup I started out by installing homebrew and installing the same basic dependencies via homebrew:

• cmake
• autoconf
• automake
• libtool
• pyenv

And then I used pyenv to install Python 3.9.9 as well as the ue4cli tools
pip3 install ue4cli conan-ue4cli

The steps described here https://docs.adamrehn.com/conan-ue4cli/workflow/installation still work well for UE4 (version 4.26.2)

This part works fine:
ue4 conan build "mergetiff-ue4==0.0.6"

This does not:
ue4 conan build "gdal-ue4==2.4.0"

The initial failure:

The first error you'll get is: configure: error: cannot find required auxiliary files: config.rpath.
I used this OSGeo/gdal#4341 (comment) to get around it. Opening /Users/{Username}/.config/conan-ue4cli/recipes/gdal-ue4/2.4.0/conanfile.py and patching it like this:

# Patch out iconv support under Mac OS X and patch GDAL v2.4.0 for XCode 12.x
if self.settings.os == "Macos":
    self.run("sed -i '' 's/-D_XOPEN_SOURCE=500 //g' ogr/ogrsf_frmts/geojson/libjson/GNUmakefile")
    self.run("touch config.rpath") # Add this line
    tools.replace_in_file("./configure", "iconv.h", "iconv_h")

The second error

When running ue4 conan build "gdal-ue4==2.4.0" again, you'll now get this error:

The error is configure: error: cannot run C compiled programs..

Unfortunately, I am not quite sure what to try next. I tried updating the command line tools and looked at some tips posted in here https://stackoverflow.com/questions/53038856/macos-configure-error-cannot-run-c-compiled-programs but those seem to apply to older macOS/XCode versions.

Have others attempt to build UnrealGDAL for macOS Monterey / XCode 13 recently?

[falcon4ever]

To follow up, I don't think it's a macOS Monterey or XCode 13 thing, it has something to do with the c/c++ tooling. Below are my findings with a workaround.

I downgraded my intel mbp and used this environment:

• macOS Catalina 10.15.7
• XCode 12.4 (Installed the commandline tools xcode-select --install)
• Unreal Engine 4.26.2 (installed in /Users/Shared/Epic Games/UE_4.26)
• Latest Pyenv with Python 3.9.10
• Latest Homebrew

Setting things up
The same as what the online instructions tell you to do.

pip3 install ue4cli conan-ue4cli
cd /Users/Shared/Epic\ Games
git clone --depth=1 -b 4.26.2-release git@github.com:EpicGames/UnrealEngine.git 
cd /Users/Shared/Epic\ Games/UnrealEngine
./Setup.sh 
./GenerateProjectFiles.sh
ue4 setroot /Users/Shared/Epic\ Games/UnrealEngine 
ue4 conan generate
ue4 setroot /Users/Shared/Epic\ Games/UE_4.26

Installing basic build tools
brew install cmake (this will install v3.22.2)
brew install autoconf (this will install 2.71)
brew install automake (this will install 1.16.5)
brew install libtool (this will install 2.4.6_4)

When you try to build unreal gdal:
ue4 conan build "gdal-ue4==2.4.0" "mergetiff-ue4==0.0.6"
You will get the first error as reported in the previous post about the configure: error: cannot find required auxiliary files: config.rpath issue.

Looks like autoconf (v2.71) is the problem here. To fix it, you can do the following:

brew uninstall --ignore-dependencies autoconf
brew install autoconf@2.69
brew link autoconf@2.69
echo 'export PATH="/usr/local/opt/autoconf@2.69/bin:$PATH"' >> ~/.zshrc

Open up a new terminal and try:
ue4 conan build "gdal-ue4==2.4.0" "mergetiff-ue4==0.0.6"

You will now run into the same configure: error: cannot run C compiled programs. problem.

1. I'm unsure why this happens, but the first thing you should do is open up the file /Users/xxx/.conan/data/gdal-ue4/2.4.0/adamrehn/4.26/build/31e5be5d8de691493e5c836dc5677702c9c6dacb/gdal/gdal/config.log
2. There should be a line like It was created by configure, which was generated by GNU Autoconf 2.69. Invocation command line was at the top.
3. Copy that ./configure ... thing to you text editor.
4. If you open up a new terminal and go to /Users/xxx/.conan/data/gdal-ue4/2.4.0/adamrehn/4.26/build/31e5be5d8de691493e5c836dc5677702c9c6dacb/gdal/gdal/ (modify the username and hash), and run that exact ./configure command, you'll see it succeed just fine.
5. When you try to do make && make install, it will build fine but it will fail to install (it's trying to install it in /lib).
6. With this knowledge you should be able to apply a workaround in the /Users/xxx/.config/conan-ue4cli/recipes/gdal-ue4/2.4.0/conanfile.py recipe.
7. Open up the conanfile.py
8. Replace autotools.configure(args=self.configure_flags()) with self.run("xxx") and replace the xxx with the entire ./configure command that you found in config.log
9. Replace autotools.make(target="install") with self.run("make DESTDIR=/Users/xxx/.conan/data/gdal-ue4/2.4.0/adamrehn/4.26/package/31e5be5d8de691493e5c836dc5677702c9c6dacb install") (again replace the username and the hash here)
10. Run ue4 conan build "gdal-ue4==2.4.0" "mergetiff-ue4==0.0.6" and it will build gdal fine, cache/package the lib and it should now be usable for UnrealGDAL.

I'm not entirely sure why configure via the recipe acts differently than running it directly from the terminal (it seems to add additional PATHs as well) but at least the above will allow you to generate working macOS binaries.

[falcon4ever]

After doing the above, you should probably do the following:

• Go to {MyProject}/Plugins/UnrealGDAL/Source/GDAL
• run: ue4 conan precompute ue4.26-Mac

On the mac you might have issues with UE4 launching and building the project giving you this error:
Creating makefile for xxxEditor (no existing makefile) ERROR: Unable to instantiate module 'GDAL': System.ComponentModel.Win32Exception (0x80004005): ApplicationName='conan', CommandLine='install . -g=json --profile=ue4.26-Mac-x86_64'

That's because this: https://github.com/TensorWorks/UnrealGDAL/blob/master/Source/GDAL/GDAL.Build.cs#L21

I'm not sure if this is a macOS specific issue but you can patch it as follows:

String.Format("{0}-{1}", target.Platform.ToString(), target.Architecture) :
			target.Platform.ToString();

to

String.Format("{0}", target.Platform.ToString()) :
			target.Platform.ToString();

which will turn ue4.26-Mac-x86_64 into ue4.26-Mac and keep UE4 happy.
