bug in https://github.com/inkeliz/gio-cmd

I am getting when I do a iOS build using our go-cmd at https://github.com/inkeliz/gio-cmd

clang: error: SDK does not contain 'libarclite' at the path '/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/arc/libarclite_iphonesimulator.a'; try increasing the minimum deployment target

when I use https://github.com/gioui/gio-cmd I dont get this bug.

go run gioui.org/cmd/gogio -target ios -arch amd64 -o .bin/ios_amd64.app .
go run gioui.org/cmd/gogio -target ios -arch arm64 -o .bin/ios_arm64.app .

Can you try with -minsdk 15?
If that works, we need to increase the minimum SDK, from 11 to 15, or other.

Side-note: I'm currently using -minsdk 18, since I'm publishing it on a third-party store and the minimum is 18 for iPad.

Thanks @inkeliz

If you know how , from a terminal, to configure the SDK used please let me know.

So it’s repeatable in CI.

I don't know how to install the latest SDK by terminal. Usually you go to "XCode" > "Settings" > "Components" and get the latest iPhone one. Also, update XCode to the latest version, in AppStore.

However, if you already had the latest version, just include -minsdk flag to force compile with that:

go run gioui.org/cmd/gogio -target ios -arch arm64 -o .bin/ios_arm64.app -minsdk 18 .

I'm not sure if 18 is required, maybe it can be 15, 16, 17 (...). Omitting -minsdk will use 11, which is quite old.

Ah perfect . That will make it reproducible

Ok trying out the -minsdk flag :)

using latest from:

https://github.com/gioui/gio -b v0.6.0
https://github.com/inkeliz/gio-cmd

On the hyperlink demo, lipo is complaining. So I guess https://github.com/inkeliz/gio-cmd/blob/main/gogio/iosbuild.go is not handling the -minsdk properly....

I marked the error for each one that fails...
