I have a weird problem with building a ios forms app.
We have made a dll of a native library (openCV2) with some functions we need.
we have made a PoC that builds and runs just fine, but when we take it to the "real" app it cant build.
right before the build fails i see in the log:
/Library/Frameworks/Xamarin.iOS.framework/Versions/Current/bin/mtouch @/Users/xxx/Library/Caches/Xamarin/mtbs/builds/xxx.iOS/xxxx/obj/iPhone/Debug/device-builds/iphone11.2-14.6/response-file.rsp -v -v -v -v --gcc_flags=-ObjC
while on the PoC app the same line is:
/Library/Frameworks/Xamarin.iOS.framework/Versions/Current/bin/mtouch @/Users/xxx/Library/Caches/Xamarin/mtbs/builds/xxx.iOS/xxxx/obj/iPhone/Debug/device-builds/iphone11.2-14.6/response-file.rsp
i know the "-v -v -v -v" is from my additional mtouch args. but no where (that i can find) is the gcc_flags set and i cant find a way to remove it.
what i have tried with no luck:
linking Foundation framework in the additional mtouch args.
linking Foundation framework in the LinkWithAttribues.cs file in the binding project
none, sdk-only and all linking.
looked at diffrenses in the project files
made all the changes i can think of in the LinkWith file eg. linker flags, smart linking c++ and the like.
tried with and w/o this linker flag L/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphonesimulator/ -L/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphoneos -Wl,-rpath -Wl,@executable_path/Frameworks
made sure the code in the implementation and PoC is 100% the same
made the iOS build options 100% the same in project and PoC
installed the xamarin.swift nuget
tried both 4.8 and 5.0 xamarin forms
im running
vs for mac 8.10 (for binding project)
vs2019 16.10.1 (for app building)
xamarin.ios 14.19 on both
does anyone have a idea on what is going wrong here?
Im at the end of my rope, any help or ideas on where to look would be greatly appricieted.
here is the complete "failing" build log:
