iOS Build xCode 12 Errors

Has anybody successfully built their LOVE game for iOS using xCode 12?

I'm receiving a host of errors relating to math.h. They all take the form of:

Code: Select all

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/math.h:769:10: No member named 'labs' in the global namespace; did you mean simply 'labs'?"
/Users/blank/Downloads/love-11.3-ios-source/src/libraries/glad/glad.cpp:13:10: In file included from /Users/blank/Downloads/love-11.3-ios-source/src/libraries/glad/glad.cpp:13:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS14.0.sdk/usr/include/assert.h:44:10: In file included from /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS14.0.sdk/usr/include/assert.h:44:
 /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/stdlib.h:100:10: In file included from /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/stdlib.h:100:
 
Any ideas? I've tried reinstalling xCode and the command line tools, but no go.

Thanks!

I am seeing the same issue. I haven't found a solution, but I think this thread is relevant: https://stackoverflow.com/questions/586 ... nbit-in-th

Here's a quote from that thread:
To summarise: On Catalina, /usr/include is purged and protected by SIP. Thus, any project that expects the C headers to be found there will fail to compile. If I remember correctly, Apple recommends to file bug reports to projects that expect C headers in /usr/include.
In the case of Love2d and Xcode, I tried changing the `-isysroot` flag to the value of `xcrun --show-sdk-path` (or `xcrun --show-sdk-path -sdk iphoneos` for iOS) and this didn't fix the issue. I will post again if I find a solution.

For reference, my machine is on Catalina 10.15.6 and Xcode 12.0. I just updated Xcode today and the issue appeared.

I pushed this change to the github repository which should fix it, let me know if it works for you: https://github.com/love2d/love/commit/6 ... 4677a0cd7e

You can either duplicate those changes into your copy of love's source, or grab the latest source from github and put the library dependencies in the new copy.

Thanks a lot, slime. You saved me from hours of keyboard head bashing.

I'm still getting this error in LÖVE version 11.3 and Xcode version 12.2. I'm also using an M1 Mac mini, which could be related.

EDIT: Got it working, just needed to clone the latest source from GitHub rather than grabbing it from the releases page.

I verified @markoren trick of cloning vs. downloading the source from the releases page resolved the compiler errors on Xcode 12.4
