MacOS/ARM build of libcurl is failing

[hurlybird]

I'm getting the following build errors from libcurl for arm64 on MacOS. After digging, I suspect the output regarding VS projects is misleading since the x86_64 build seems to complete properly. A big problem is that the log files mentioned aren't getting generated--or are getting deleted before I can check them. Any suggestions?

On any error the build script lists all of the *.log files from the builds. They are not in any particular order which is probably something I should look to improve. In your example, the build is failing building the arm64 MacOS (M1) binary:

Building curl-7.74.0 for arm64 (MacOS 11.1)
==> /tmp/curl-7.74.0-arm64.log <==
make[2]: *** [curl] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all-recursive] Error 1

It doesn't show enough for us to see the reason for the build error. Try cat /tmp/curl-7.74.0-arm64.log to see what else may be above the make failure.

The second build log is actually a successful one (you can disregard the Windows reference as that is part of the curl make process and doesn't result in any errors).

Yeah, I figured as much after looking at it more closely. Unfortunately the log files either aren't getting created or are being deleted. I can see some of the logs for the openssl build while the build is still ongoing, but even those get deleted at some point.

I only need the iOS build so I hacked up the script to only build the pieces I need as a workaround. I'll probably dig through it more if/when I need the MacOS version.

Code formatting ugly in last msg, So i copied here:
