full path when linking with mali library #15

Closed MastaG closed 2 years ago

MastaG commented 2 years ago

Hi @JeffyCN

It seems when building the shared objects. It tends to put the full path to the mali driver instead of just the filename.

ldd /usr/local/lib/libgbm.so.1
    linux-vdso.so.1 (0xbed53000)
    libmali_hook.so.1 => /usr/local/lib/libmali_hook.so.1 (0xb6f00000)
    libc.so.6 => /lib/libc.so.6 (0xb6d80000)
    /mnt/sdcard/src/rockchip_mirrors/optimize_3/arm-linux-gnueabihf/libmali-midgard-t62x-r12p0-04rel0-wayland.so (0xb5d00000)

    libwayland-server.so.0 => /lib/libwayland-server.so.0 (0xb5c30000)
    libstdc++.so.6 => /lib/libstdc++.so.6 (0xb5a50000)
    libm.so.6 => /lib/libm.so.6 (0xb59f0000)
    libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb59c0000)
    libffi.so.8 => /lib/libffi.so.8 (0xb59a0000)

Is there a way to fix this?

JeffyCN commented 2 years ago

it that a 3rd party libmali?

try to normalize it using the scripts/normalize.sh

JeffyCN commented 2 years ago

it will use full path instead of soname when there's no soname ;)

MastaG commented 2 years ago

Ah yeah, that explains it :) I didn't run normalize.sh yet, but I checked out the scripts. It should also fix the .dynsym local symbol at index 3 (>= sh_info of 3) if I read it correctly. It's now building lief using pip3 which seems to take a while. I'll run the scripts and rebuild once it's done.

It's a not a 3rd party libmali but the user-space driver for ODroid XU3/XU4 from the ARM website for running on wayland/gbm. It's pretty old and I've hex edited it to rename EGL_KHR_platform_gbm to EGL_MESA_platform_gbm for better compatibility. But tossing it into your project makes up for all the missing gbm_ symbols :+1:

JeffyCN commented 2 years ago

right, building lief from pip3 is single threaded, which is slow. the build dir is under /tmp/, so i run make -jN there manually to speed it up.

MastaG commented 2 years ago

It seems to work now :+1:

yep and it boots into Gnome 42 (wayland) again. Thanks for pointing me to the scripts !
