2 years ago 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_4.26Installing 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"' >> ~/.zshrcOpen 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.
- 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 - There should be a line like
It was created by configure, which was generated by GNU Autoconf 2.69. Invocation command line wasat the top. - Copy that
./configure ...thing to you text editor. - 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./configurecommand, you'll see it succeed just fine. - 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). - 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.pyrecipe. - Open up the conanfile.py
- Replace
autotools.configure(args=self.configure_flags())withself.run("xxx")and replace thexxxwith the entire./configurecommand that you found inconfig.log - Replace
autotools.make(target="install")withself.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) - 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.
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 https://github.com/TensorWorks/UnrealGDAL/issues/1#issuecomment-758929405
I'm still on an Intel Macbook Pro, but there are a few things that have changed:
On a fresh setup I started out by installing homebrew and installing the same basic dependencies via homebrew:
And then I used
pyenvto install Python 3.9.9 as well as the ue4cli toolspip3 install ue4cli conan-ue4cliThe 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 https://github.com/OSGeo/gdal/issues/4341#issuecomment-906294159 to get around it. Opening/Users/{Username}/.config/conan-ue4cli/recipes/gdal-ue4/2.4.0/conanfile.pyand patching it like this: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?
