Xtensa-esp32s3-elf/bin/ld.exe: group ended before it began (--help for usage)

PlatformIO IDE
#1

I try to compile the esp-who example for the ESP32-S3-EYE board and got the following error message during the linking:

.platformio/packages/toolchain-xtensa-esp32s3/bin/../lib/gcc/xtensa-esp32s3-elf/8.4.0/../../../../xtensa-esp32s3-elf/bin/ld.exe: group ended before it began (--help for usage) collect2.exe: error: ld returned 1 exit status *** [.pio\build\debug\firmware.elf] Error 1

My configuration is the following:

How can I fix the issue?

What’s the linker command? CLI → pio run -v -j1 please.

These string macros don’t look right at all, they should be stringifed.

    '-D APP_NAME="esp32-s3-eye"'
    '-D APP_VERSION_POST="debug"'

Thanks. I have the conversion in my code. But it´s a good hint to move it into the config file.

#4

Well somehow the linking command containsg this piece

-Wl,–Map=C:/Users/konta/Desktop/ESP32-S3/.pio/build/debug/ESP32-S3.map -Wl,–cref -Wl,–end-group -Wl,–gc-sections -Wl,–start-group -Wl,–undefined=uxTopUsedPriority

Where a group is indeed ended before it is started, so the linking error is right.

Is this reproducable with a simpler project? Can you upload it?

Hi,

I´m not sure where this error comes from, because an empty project doesn´t produce the error. But I have uploaded my project for you without esp-camera, esp-dl and esp-sr.
