As for uchar - can you tell me OSX and Xcode version?

I have no OSX right now. Can you search uchar.h in your system or investigate, what's wrong with it? In worst case, you can comment it and replace _char16t with unsigned short.

the same with me，who resolve it?

Well, Linux has uchar.h (#63), but OSX — does not.

May be it is easier to replace char16_t with unsigned short in include/sciter-x-types.h.

[iazkaban]

Now,I replaced:

char16_t with unsigned short size_t with unsigned int

then i got:

MyMac 😂 ➜ download git:(master) ✗ go build # github.com/sciter-sdk/go-sciter cgo-gcc-prolog:1091:8: error: field has incomplete type 'VOID' (aka 'void') cgo-gcc-prolog:1430:8: error: field has incomplete type 'VOID' (aka 'void')

[pravic]

Any more details of this error? Surrounding lines may be? I could not figure out which field has type VOID.

[iazkaban]

All I showed is the whole message

but i think it's sciter-x-types.h 's line 148

hey,it's too late for me,i will goto sleep,i will reply you tomrrow if you need~

[pravic]

No, it is about some struct with VOID field.

[iazkaban]

waiting for a version can run on osx~

[xpsuper]

the same with me，who resolve it?

[raundn]

I've struggled with this issue for a day or so and have managed to compile and (successfully) run a couple of sciter programs (the ones from the examples/ directory) on my Mac.

Here's what I've done:

1. I've replaced

   #include <uchar.h>

   with

   
   #include <stddef.h>
   #include <stdint.h>

typedef uint16_t char16_t; typedef uint32_t char32_t;

The first include is for `size_t`, the second one is for `uint16_t` and `uint32_t`. I'm not sure this is the _best_ way to fix this (I suspect it isn't), but it _is_ a fast one.

2. I've then compiled and installed the sciter lib (not the apps, mind you!) with a newer gcc:

CC=/opt/local/bin/gcc-mp-4.9 CXX=/opt/local/bin/g++-mp-4.9 go install

As the `-mp-4.9` suffixes indicate, my GCC was installed from MacPorts, but I think any sufficiently recent version will do.

If you get the "field has incomplete type 'VOID' (aka 'void')" error doing this, you're using a wrong compiler.

Also, note that I've said 'go install', not 'go build' here.

3. Lastly, I've compiled a sample app using Apple's (stock) version of clang:

$ which clang /usr/bin/clang $ which clang++ /usr/bin/clang++ $ clang --version Apple LLVM version 8.1.0 (clang-802.0.42) Target: x86_64-apple-darwin16.6.0 Thread model: posix InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

If, doing this, you get an error like this one:

/System/Library/Frameworks/CoreData.framework/Headers/NSPersistentContainer.h:37:18: error: unknown property attribute before ',' token @property (strong, readonly) NSPersistentStoreCoordinator *persistentStoreCoordinator;

(note the `@property`), you're using a wrong compiler.

To summarize, the sciter lib has to be compiled with (a recent version of) GCC, while for compiling apps one has to use stock clang. This is why it's crucial to say 'go install' at step 2. Otherwise attempting to compile an app would attempt to (re)compile the library, which would fail under clang.

@raundn Big thanks!

I updated that header, it is compiled fine under Linux and Windows. Checked with Go 1.8 (gcc 6.3.0 and mingw 5.3.0).
