This simple patch gives me an error. ![image](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/2X/b/ba185a9b9c904510fd1d8ae0e718499317cba5ad.png) In order to compile I have to comment this line in `digital-write` node ```auto //#pragma XOD evaluate_on_pin disable ``` error: ```auto Begin compiling code for the board Arduino Uno 📦 C:\Users\Cesar\AppData\Local\Temp\xod_temp_sketchbook98XhiA\xod_1601190379205_sketch\xod_1601190379205_sketch.ino: In function 'void xod::detail::handleDebugProtocolMessages()': C:\Users\Cesar\AppData\Local\Temp\xod_temp_sketchbook98XhiA\xod_1601190379205_sketch\xod_1601190379205_sketch.ino:1331:35: error: 'struct xod::TransactionState' has no member named 'node_0_isOutputDirty_OUT'; did you mean 'node_2_isOutputDirty_TICK'? g_transaction.node_0_isOutputDirty_OUT = true; ^ ~~~~~~~~~~~~~~~~~~~~~~~ node_2_isOutputDirty_TICK C:\Users\Cesar\AppData\Local\Temp\xod_temp_sketchbook98XhiA\xod_1601190379205_sketch\xod_1601190379205_sketch.ino: In function 'void xod::runTransaction()': C:\Users\Cesar\AppData\Local\Temp\xod_temp_sketchbook98XhiA\xod_1601190379205_sketch\xod_1601190379205_sketch.ino:1391:55: error: 'struct xod::TransactionState' has no member named 'node_0_isOutputDirty_OUT'; did you mean 'node_2_isOutputDirty_TICK'? ctxObj._isOutputDirty_OUT = g_transaction.node_0_isOutputDirty_OUT; ^ ~~~~~~~~~~~~~~~~~~~~~~~ node_2_isOutputDirty_TICK Error during build: exit status 1 Compilation failed Command Process exited with code 1 The generated C++ code contains errors.

Hello. I had exactly the same error. And I also fixed it by deleting or commenting out this line. This bug is related to tweak. It works with other nodes, but doesn’t work with tweak. By the way, I still don’t understand what function they perform #pragma XOD evaluate\_on\_pin disable #pragma XOD evaluate\_on\_pin enable input\_UPD #pragma XOD error\_raise enable ---

Very strange, I was able to fix the error without changing the patch. ![image](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/2X/d/dbc25ec782aa29e746da628c5f3dabe170409740.png) ![image](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/2X/0/05d37c0484071ae861146019109e81a9d633e411.png) As you can see, I just drew another line from the tweak to another patch ---

Thanks for commenting, I noticed something similar before when writing a library, if I added the line and had digita-write nodes, the error would appear. Now this seems to be a bug. I also see that the c ++ implementation of your node does not seem to be updated to 0.35.x ---

No, I have the most recent version. I honestly don’t know why the patch hasn’t been updated. And by the way, even if there is a new version, you can still write in the old way. ---

There is a fork of the xod folder inside libraries, delete it and start xod again. If you’ve ever moved a node or changed something, a copy of the folder is created. This change occurs when you save any patch. ---

Thanks for the report. Just released a new version 0.35.3 with the fix of this problem. ---
