From what I understand you're compiling with CMake and with
LYX_EXTERNAL_ICONV set to OFF. If I do that, it compiles successfully
for me (although I have to turn off -Werror because there are warnings).
I was just using defaults:
mkdir build
cd build
cmake ..
and that's it. If I set LYX_EXTERNAL_ICONV to ON, then it builds. The
error seems to be in building iconv itself.
This is on Fedora 41, with gcc 15.1.1.
