Build is Different Based on [env] name

Development Platforms
1

First off: I am new to PlatformIO. I have done little with it and am working on my first serious project using it.

The issue I am having is that, while using PlatformIO in VS Code on a ESP32 Dev Kit C V4 board and Arduino framework, the code builds differently based on the name that I give the environment. Why is this? Should I be concerned about the device operating differently, or is it simply that there are non-functional values that change in built code (e.g. a version/platform string only used for viewing purposes)?

I can provide other detailed information if it helps, but for now, here’s the build output spit out to the terminal:

Have you run a binary diff against these files or can you provide both .elf files (from .pio\build\..)? What is the exact content of the platformio.ini or the environment names?

It’s very possible for C code to include it’s own file path via the __FILE__ macro, so if this is used for debugging purposes (in e.g. debug strings or asserts), then the result may differ because for different environment names, as libraries are installed to different folders ( .pio\libdeps\<environment name>\) so those strings can be of different length or content.

Thanks for the quick response!

I have run a diff on the output that I threw in the initial post, there are a lot of differences in build execution. However, it just looks like build order is different for each environment/config.

I just ran a diff on the elf files, and there are a lot of differences, though I can’t tell what the differences mean.

Here’s the platformio.ini file:

Not sure how to upload elf files here, after I figure that out I’ll post them.

Here’s the two elf files:
