Dear TI,
Due to suggestion from e2e.ti.com/.../j721excpxevm-tda4vm-app_srv_camera-fails-to-replace-car-model-pod.
I'm trying to integrate assimp with ti-processor-sdk-rtos-j721e-evm-09_00_00_02.
Step 1:
I first download the latest assimp-5.3.1.tar.gz.
After I decompressed it, I used the following command to compile. I don’t know if there is anything wrong. Please help me correct it.
cd /home/georgelin/ti-processor-sdk-rtos-j721e-evm-09_00_00_02_assimp_work/assimp-5.3.1
cmake.
make -C /home/georgelin/ti-processor-sdk-rtos-j721e-evm-09_00_00_02_assimp_work/assimp-5.3.1/ all TOOLS_INSTALL_PATH=/home/georgelin/ti BOARD=j721e_evm SOC=j721e CORE=mcu2_0 BUILD_PROFILE=release -s;
Then we will get
/home/georgelin/ti-processor-sdk-rtos-j721e-evm-09_00_00_02_assimp_work/assimp-5.3.1/bin/libassimp.so
/home/georgelin/ti-processor-sdk-rtos-j721e-evm-09_00_00_02_assimp_work/assimp-5.3.1/bin/libassimp.so.5
/home/georgelin/ti-processor-sdk-rtos-j721e-evm-09_00_00_02_assimp_work/assimp-5.3.1/bin/libassimp.so.5.3.0
Among them, libassimp.so and libassimp.so.5 are Symbolic links pointing to libassimp.so.5.3.0.
Step 2:
In order to compile pass, I copied a copy of /home/georgelin/ti-processor-sdk-rtos-j721e-evm-09_00_00_02_assimp_work/assimp-5.3.1/include/assimp/ to /home/georgelin/ti-processor-sdk- rtos-j721e-evm-09_00_00_02_assimp_work/vision_apps/kernels/srv/gpu/3dsrv/assimp.
Because I will modify /home/georgelin/ti-processor-sdk-rtos-j721e-evm-09_00_00_02_assimp_work/vision_apps/kernels/srv/gpu/3dsrv/car.cpp to read the glTF file in its InitView().
But link error keeps happening when compiling. as follows

I tried two ways to make libassimp.so findable by ld.
1. Modify /sdk_builder/makerules/makefile_vision_apps.mak, but it has no effect.
Revise
$(MAKE) -C $(VISION_APPS_PATH)
for
$(MAKE) -C $(VISION_APPS_PATH) -L $(PSDK_PATH)/assimp-5.3.1/bin
2. Modify
/vision_apps/apps/concerto_mpu_inc.mak
/vision_apps/kernels/srv/gpu/3dsrv/concerto.mak
/vision_apps/kernels/srv/gpu/concerto.mak
/vision_apps/platform/j721e/rtos/concerto_a72_inc.mak
Add the following definition:
LDIRS += $(PSDK_PATH)/assimp-5.3.1/bin
It has no effect either.
So I want to ask you, how to solve this problem?
