Dear Fabien and Jussi,
Thank you very much for your time and concern.
After your suggestion I tried to find out all those packages installed by "bash
install-deps". However I found that these deps are required to build JIT
version of Lua, as mentioned on the official Torch website.
So instead I used Lua 5.2 instead of JIT, which does not require to run "bash
install-deps" first. And this time after I generated Torch recipe using devtool
and tried to build it, the compilation proceeded to nearly 96%, then thows an
error saying:
Could NOT find Wget (missing: WGET_EXECUTABLE)
| -- Could NOT find MD5 (missing: MD5_EXECUTABLE)
| -- curl found instead of wget
:/home/abayiz/trunk/poky/build-hello/tmp/work/i586-poky-linux/torch/2.1devel+git999-r0/recipe-sysroot-native/usr/bin/curl
| CMake Error at exe/luajit-rocks/luarocks/CMakeLists.txt:77 (MESSAGE):
| MD5 checker not found
However in the 'devtool' generated recipe file, I found this line:
# NOTE: unable to map the following CMake package dependencies: CUDA CUDNN BLAS
ARM Torch SSE MD5 MAGMA LAPACK Readline
DEPENDS = "wget jpeg ncurses libpng"
Seems like wget is already set as built-time dependency but the system doesn't
see it, as well as MD5. Do you have any suggestion for that?Thank you again.
Best.

Usually we add build dependencies with DEPENDS = "..." and runtime dependencies
with RDEPENDS =
"..."
So you need to check dependencies installed by "bash install-deps".
Can you list them? Maybe recipes exists in which case you have to add them to
the variable described
above.
