Hello All,

While building casync using ninja build I am facing below errors related to /usr/bin/ld: . . .error adding symbols: file in wrong format

I am following "casync" build guideline from https://github.com/systemd/casync#building-casync , it uses "meson " along with ninja build.

If build failures persist, run "meson setup --wipe" to rebuild from scratch
using the same options as passed when configuring the build.
To change option values, run "meson configure" instead.

[10/31] Compiling C object test-camatch.p/test_test-camatch.c.o
ninja: build stopped: subcommand failed.

I am using Buildroot as build system and after following similar post in https://stackoverflow.com/questions/27967802/libstdc-so-error-adding-symbols-file-in-wrong-format I changed the PATH environment like:

/root/raspcm4/sources/output/host/bin/:/root/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/root/raspcm4/sources/output/host/aarch64-buildroot-linux-gnu/sysroot/usr/bin

But still, I end up getting the same errors

Can anyone please let me know how to resolve this issue? Is there any ninja build option to be selected in Buildroot?

Your help will be much appreciated.

Thanks in advance

P.S: Please let me know if any info is missing here
