Compiling errors

Hi, Tried to compile this project and got the following error report:

Arduino: 1.8.12 (Windows 10), Board: "LOLIN(WEMOS) D1 R2 & mini, 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), 4MB (FS:2MB OTA:~1019KB), v2 Lower Memory, Disabled, None, Only Sketch, 921600"

I'm pretty sure the last three errors just flow on from the first three. tim

hmm 🤔

to me it seems like something wrong with the ESP libraries; as it's something relating to FS not being defined in their functions...

I'll investigate this a little more and try and get a solution, please wait

Issue relates to having the latest version of ESP8266 boards installed.

If you go to " Tools > Boards > Boards manager " and downgrade ESP8266 to "2.5.2" ( and set exceptions to disabled ) then it will compile fine.

Related issues:

• https://github.com/luc-github/ESP3D/issues/352

it seems like the esp8266 guys have a "update and forget" problem as some other code bases rely on changes in the 2.4.2 versions of ESP, breaking in 2.5.2

• https://github.com/esp8266/Arduino/issues/5784

For the time being I'll have to amend the project page and mention it specifically. We might have to work on a 2.6.3 branch in the future.

Can you confirm that it works?

Wow, thanks for the fast response. Have to wait til I get home from work and I'll get on it.

Hi, Yes, I downgraded to 2.5.2, and it compiled and loaded, but I had to then upgrade again for the Data Upload tool to work. A bit of shuffling around but it's all working well now. Thanks for your help! tim
