Problem building the project using Platformio and ESP32

[phenzao]

I am trying to build the NeoPixelTest using Platformio but I get this error: "undefined reference to `bitbang_send_pixels_800'. I tried to build the project with arduino IDE and it is working correctly. Any one have any idea what I need to do for the Platformio to work?

[Makuna]

I don't specifically support PlatformIO issues.

But, look through the verbose compile output and look for warnings/errors. Also grab any relevant lines that reference the library and include those. Maybe someone else with more knowledge with PlatformIO can help.

[EBZ-Krisemendt]

i experienced several problems like this with external libraries using platformio. started to manually clone those in each projects lib folder. so far all those "undefined reference"/"not found"/etc errors seemed to be fixed by this procedure.

[Makuna]

A shot in the dark, but check if the includes if they use double quote (") or greater/less than (<>) around the file name; quote is supposed to be local files, greater than equal is supposed to be external libraries; with Arduino this isn't often an issue so you see incorrect use of them out there in libraries.

[hallard]

I've got the same problem, copying library in local project lib folder does not solve it.

Here the full log output if it can help

Hi,

I have exactly the same problem and it is a shame :(

Hope I will find an answer somewhere!

[Makuna]

What version of the Esp32 Arduino are you using?

bring it up on some platformio forum/support, as its an incompatiblity issue.

[florian-guillemard]

I'm working on the heltec wifi lora 32, this model precisely : https://www.banggood.com/fr/Wemos-TTGO-LORA-SX1278-ESP32-0_96OLED-16-Mt-Bytes-128-Mt-bit-433Mhz-For-Arduino-p-1205930.html?cur_warehouse=CN

[Makuna]

A lot has changed with Esp32 (formal release has been made) and I have since added hardware support. Is this issue still a problem?

[Makuna]

closing due to lack of communications. I don't believe this issue really has anything to do with this library.

[VioletGiraffe]

Sorry to bother you as this indeed is not a library issue per se, but having just spent 20 minutes figuring it out, I want to report my findings as this issue is among the first Google results on the topic.

Apparently, typeof is a GCC extension. As such, it is disabled when the program is compiled with std=c++XX. There are two ways to solve this:

1. Use __typeof__ instead of typeof (can be done with a global define: build_flags = -Dtypeof=__typeof__
2. Use std=gnu++XX.

[Makuna]

@VioletGiraffe The typeof is not in NeoPixelBus, it is in the Esp32 Arduino.

[VioletGiraffe]

@Makuna: understood, removed the post scriptum. Thanks for the awesome library, by the way!

[osmeest]

Seasoned C++ developer, I'm a bit disappointed by the quality of ESP32 libraries. They suck big time when it comes to C++. All those #define creating incompatibilities between libraries. As if namespaces, templates, ... were there for nothing. @VioletGiraffe your last comment saved me from hours of torturing myself. @Makuna, indeed, this has nothing to do with your lib which is very nice but the solution to my problem happened to be here :)
