Build fails on macOS 11

[genericptr]

Any ideas how to resolve this?

The script is trying to build a 32-bit Intel version, which Xcode no longer supports.

We need to update this to do only 64-bit Intel and 64-bit ARM.

(For now: just don't use gcc-fat.)

Makes sense, thanks. Is there any alternative script you can suggest? All mac users on 10.15+ are 64-bit only now so we're kind of stuck.

[icculus]

Try this with clang-fat.sh, which I just added. Same idea, but it works with 64-bit Intel and 64-bit ARM on Big Sur.

(the x86_64 part of the final build will work back to macOS 10.6, the arm64 part needs macOS 11.0.)

I tried the default command from the wiki and it seems to have built now but I don't see where the library is. Is this the same as clang-fat.sh?

cd SDL
mkdir build
cd build
../configure
make
sudo make install```

then I tried this:

build$ CC=../build-scripts/clang-fat.sh ../configure ; make

And got errors...

I made a new issue for this. #4433

but I don't see where the library is.

Assuming sudo make install worked, it copied it into /usr/local/lib/libSDL2-2.0.0.dylib (and it should be a Universal Binary if everything went right).

If you didn't want it installed system-wide, it should be sitting under your "build" directory in build/.libs/libSDL2-2.0.0.dylib (yes, that's build/build/.libs) before the sudo make install command, and you can just grab it directly.

The first steps you listed (without the CC=../build-scripts/clang-fat.sh part) will work, but they'll only build for the current architecture (arm64 on an M1 mac, x86_64 on the Intel macs). If building for your own personal use, this is actually what you want. All the tapdancing to build universal binaries and things that are compatible with older macOS releases is just if you intend to distribute the build to other people and want maximum compatibility, of course.
