emmake is a helper for make, setting various environment variables so that emcc etc. are used. Typical usage:

emmake make [FLAGS]

(but you can run any command instead of make)

[fouvy]

After I remove extern "C" { // C -> JS } from src/index.cpp This error is fixed.

[fouvy]

There is another error: &serial_bridge::encrypt_payment_id member doesn't exist! So, I remove emscripten::function("encrypt_payment_id", &serial_bridge::encrypt_payment_id); from src/index.cpp Then, There is another error: mymonero-core-js/src/emscr_async_send_bridge.cpp:386:50: error: no member named 'fee_mask' in 'monero_send_routine::LightwalletAPI_Res_GetUnspentOuts'

[fouvy]

After I remove those three lines about fee_mask from emscr_async_send_bridge.cpp file, I build the whole project ok now. line 386: //ptrTo_taskAsyncContext->fee_mask = *(parsed_res.fee_mask); line 411: //ptrTo_taskAsyncContext->fee_mask, line 501： //ptrTo_taskAsyncContext->fee_mask, I think fee_mask is not available now.

[paulshapiro]

Something seems quite wrong with your setup somehow. Are you sure your submodules are all up-to-date? Did you run bin/update_submodules?

[fouvy]

I have runned bin/update_submodules.

[paulshapiro]

Did you ever resolve this?

[fouvy]

I have resolve this problem.

[paulshapiro]

What was the issue?

[fouvy]

It's about build problem. Some code doesn't impl.
