	Hi, I’m facing the same scenario, except it’s for latest version of all of them Which are : Visual Studio 2019 16.5.2 Visual Micro 20.03.21.3 Arduino : 1.8.10 Tasmota 8.2 (https://github.com/arendst/Tasmota) After reading this post, I thought it should be solved, so I’m certainly doing something wrong. Your help would be greatly appreciated. Thank you. PS: Sorry, but I didn't find the button to attach log files Quote: Compiling 'sonoff' for 'Generic ESP8266 Module' sonoff.ino: 170:1: error: expected unqualified-id before 'else uint8_t multipress[MAX_KEYS] = { 0 }; \\ Number of button presses within multiwindow sonoff.ino: 171:1: error: expected unqualified-id before 'else uint8_t lastwallswitch[MAX_SWITCHES]; \\ Last wall switch states sonoff.ino: 420:1: error: expected unqualified-id before 'else sonoff.ino: 435:1: error: expected unqualified-id before 'else fallback_topic_flag = (strstr(topicBuf, mqtt_client) != NULL) sonoff.ino: 596:1: error: expected unqualified-id before 'else * 3 = Set relays to last saved state after power on sonoff.ino: 791:1: error: expected unqualified-id before 'else snprintf_P(stemp1, sizeof(stemp1), kModules[i].name) Error compiling project sources Build failed for project 'sonoff'

	Would it be possible to email the logs and the solution to us (link in yellow box at the top, include link this posting), so we can investigate further?

	We have investigated this, and a new release is available in the forum with a fix for the problem seen here with the Prototype Generation (20.03.21.7) Let us know if you have any further issues

	Hi Simon, Thank you very much for the updated version, but I'm confused, I didn't see any changes in the behaviour. My actions : Uninstalled previous version of the extension in VS2019 Downloaded your latest version : Visual.Micro.Arduino.Studio_20_03_21_7.vsix Launch VSix Installer Cleaned - Compiled - => Same Error I sent you the Compiler output and the generated tasmota.cpp It seems that AddLog_P2 is still not present Thank you for your support Best Regards

	We have found the secondary issue here, and a new release has been published to the forum (20.03.21.9), which should resolve this fully now and allow this project to build succesfully. Let us know if you have any further issues around this.

	Hi Simon, Fantastic ! Everything works seamlessly, you did a Great job. The entire projects builds successfully and can be uploaded into the ESP8266. Thank you so much for your professional efforts. Best regards Gregory

	Hi Simon, I'm back, with certainly a similar issue After several weeks of successfull compilations with your solution, I moved to the latest version of Tasmota framework (8.3.1), (solved many bugs and implemented new drivers). After upgrading entire development tool chain (including also Arduino 1.8.12 and ESP Core 2.7.1) I could successfully compile it under Arduino, but not with VMicro.

	Thanks for the update, and if it is possible to send us the full image again that would be ideal, and we will investigate further.

	Hi, Just for your info, in case you're facing same trouble with null pointer in Board Manager, it seems that there is an issue with Arduino and BoardManager freshly on-going https://github.com/arduino/Arduino/issues/10332 The package I sent over, was fully working until yesterday, but since ...

	Thanks for the package and the update. Running on my Machine the prototype discovery finds 0 prototypes, and reviewing your output it appears that the Serial Debugger is enabled as well? I am seeing a different problem at present.. To ensure we are replicating everything correctly would it be possible to send:- 1) the full build output with verbose/properties options set (as shown in the yellow box at the top) 2) the merged tasmota.cpp file from the build directory?

	Hi, After reviewing the resulting tasmota.cpp, I found something weird (at least for me) Original code in support.ino line 439 Code (C++) char IndexSeparator(void) { /* // 20 bytes more costly !?! const char separators[] = { "-_" }; return separators[Settings.flag3.use_underscore]; / if (Settings.flag3.use_underscore) { // SetOption64 - Enable "_" instead of "-" as sensor index separator return '_'; } else { return '-'; } } Resulting code in tasmota.cpp Line 2969 Code (C++) char IndexSeparator(void) { / // 20 bytes more costly !?! const char separators[] = { "-_" }; return separators[Settings.flag3.use_underscore]; * if (Settings.flag3.use_underscore) { return '_'; } else { return '-'; } } For whatever reason, it misses the closing ‘/’ of the comment Then I simply removed this comment Gave it try, and … voilà … it worked Attached the output log file, and the generated tasmota.CPP Hope this could help to nail down the root cause edit: Pushed a litlle bit further ... This works/compiles Code (C++) char IndexSeparator(void) { /* // 20 bytes more costly !?! const char separators[] = return separators[Settings.flag3.use_underscore]; / and this not anymore ... Code (C++) char IndexSeparator(void) { / // 20 bytes more costly !?! const char separators[] = " return separators[Settings.flag3.use_underscore]; */ Just a comma " difference after the '=' sign ... in a comment Hope this can help you Regards Gregory BW : The guys from Arduino fixed the trouble with the Board Manager JSON download

	Thanks for the update and analysis, this is the issue I experienced, but it didn't error and fallback so thought I had another difference... We will investigate the issue with that specific comment, and update when a fix is available.

	After deeper investigation we have improved the comment stripper to resolve this issue in the latest release 20.05.18.8 Let us know if you have any further issues around this project, and thanks again for the detail and project to replicate.
