bug: Segmentation fault error while running. #208

I'm compiling libcamera and rpicam-apps on a Raspberry Pi 5, but when I run it I encounter Segmentation fault error.

Build with the latest main commit.

Using tag v0.3.2+rpt20240927 build works fine!

Hi everyone,

I also had a Segmentation fault when trying to use libcamera with tuning file options: rpicam-still -o test.png --tuning-file /home/tactonom/tuning-files/imx219_70d.json

Error:

However, as @kiki-kanri, by changing to version tag v0.3.2+rpt20240927 I have no errors when I do: rpicam-still -o test.png --tuning-file /home/tactonom/tuning-files/imx219_70d.json

I've not been able to reproduce this in my brief testing. I'll try again tomorrow and report back.

naushir commented 7 hours ago

@kiki-kanri are you using a custom/modified json tuning file? I still cannot seem to reproduce this bug.

kiki-kanri commented 7 hours ago

@kiki-kanri are you using a custom/modified json tuning file? I still cannot seem to reproduce this bug.

I don't use json tuning files, but I do set up the compilation and linking parameters, I'll test it on a clean system sometime.

Just simply run rpicam-hello -n.

Here's the program in order and compiled by me:

naushir commented 7 hours ago

What compiler have you setup?

kiki-kanri commented 6 hours ago

What compiler have you setup?

Here's the compilation and linking parameters that work for me on v0.3.2+rpt20240927.

cflags:

-fipa-pta
-floop-block
-floop-interchange
-floop-strip-mine
-flto=4
-fomit-frame-pointer
-funroll-loops
-I/opt/openssl3/include
-march=armv8.2-a
-mtune=cortex-a76
-O3
-pthread

ldflags: -L/opt/openssl3/lib

build libcamera command:

CFLAGS="$BASE_CFLAGS" CPPFLAGS="$BASE_CFLAGS -Wno-unused-parameter" CXXFLAGS="$BASE_CFLAGS" LD_LIBRARY_PATH="/opt/openssl3/lib:$LD_LIBRARY_PATH" meson setup ./build \
        --backend=ninja \
        --buildtype=release \
        -Db_lto=true \
        -Db_ndebug=true \
        -Db_pch=true \

        -Dstrip=true \
        -Dtest=false \
        -Dtracing=disabled \
        -Dv4l2=true

Since there are so many variables, I need to find the time to test again on a clean system if the then current parameters are usable in the new version.
