Hi v4l-utils developers, The last line of contrib/gconv/meson.build reads: install_data('gconv-modules', install_dir : gconv_install_dir) This unfortunately overwrites /usr/lib/gconv/gconv-modules (installed by Glibc) and breaks iconv. For example, a simple "iconv -f iso-8859-1 -t utf-8 helloworld.c" will complain "failed to start conversion processing". I guess you need to fix the issue and release 1.26.1... -- Xi Ruoyao <xry111@xxxxxxxxxxx> School of Aerospace Science and Technology, Xidian University
