I'm using Guix with the Linux kernel and the layout of libraries are non-standard; while I was able to link the installer to the appropriate libraries, the downloaded version of the app. ignores the links given to itch-setup so the installer is effectively useless.

As such, I tried just getting v25.5.1 setup and thought I'd linked all necessary libraries to the itch binary. The libraries I've linked are:

alsa-lib
at-spi2-atk
at-spi2-core
atk
cairo
cups-minimal
dbus
expat
fontconfig
gcc
gdk-pixbuf
glib
glibc
gtk+
libdrm
libx11
libxcb
libxcomposite
libxcursor
libxdamage
libxext
libxfixes
libxi
libxrandr
libxrender
libxtst
mesa
nspr
nss
pango

As far as I can tell, all necessary libraries are now in the rpath but the app still results in a "Trace/breakpoint trap".

I've placed the output of running strace on the binary, with appropriate libraries linked, at https://controlc.com/21bdfe85.
