I have to use the project which is created by cocos creator , and the project include a module register so that i can't use < tgmath.h >.
The error of Xcode is" Use of undeclared identifier '__tg_promote1' "and"Expanded from macro 'floor' ".
I have no idea about how to work around and redeclaring the things ,please help me.
Your help is greatly appreciated .
:)

@uestchang What do you mean by module register?
Try to delete content of DerivedData folder - ~/Library/Developer/Xcode/DerivedData/*.
Which version of Xcode do you use?
Could you provide the build log?

It's so strange that when I choose the floor and right click and select JumpToDefinition , there are six items were shown;
However, in another project(an single page ios project) which work well,there are only one definition and jumpToDefiniton at <CoreGraphics/CoreGraphics.h> immediately.

I think that I found out what happen in my project ,in the project which was created by cocos creator engine , the <tgmath.h> is different from the common project.
But i still don't know how to fix this problem :((((

I think .mm extension cause Xcode complier use tgmath.h from C++ V1 instead of clang, but I have to use .mm extension in default.
In fact ,I have try to use .m to instead ,and then another error come up :(( , it seems that .mm extension is necessary for cocos creator project.

@ruslanskorb Hey bro ,is it possible to use math.h to instead tgmath.h ?
I try my best to fix the problem but all of them didn't work.

Hi @uestchang! It looks like a configuration problem. Could you try to disable Modules feature in the build settings? https://stackoverflow.com/questions/23333287/tgmath-h-doesnt-work-if-modules-are-enabled

@ruslanskorb I had tried to set Modules feature to NO ,it didn't work :( , by the way , I try to change compilers of my app target , also didn't work.

In fact , in my wrong project ,the Modules feature is NO in default . In another project which of Modules feature is YES, the cropper work well .

@ruslanskorb The whole project created by cocos creator is too big which include the engine content. I have compressed it but it's still over 100MB .Owing to this , I can't upload it here.

I upload the sampleProject.zip file to oneDrive .

The Xcode project path is "SampleProject/build/jsb-default/frameworks/runtime-src/proj.ios_mac"

@uestchang As a workaround, add the following code to RootViewController.mm after #import <RSKImageCropper/RSKImageCropper.h>:

#undef cos
#undef sin
#undef atan2
#undef pow
#undef sqrt
#undef fabs
#undef ceil
#undef floor
#undef round
