Crosscompilation

[raquelmcoelho]

How can I be able to crosscompile your lib using the tools that buildroot generate for another architecture?
(P.S The architecture I gonna use is totally unique, so I have to use the buildroot tools. However it's ubuntu based)

My Buildroot Tools looks like this:

GCC Compiler path:
/arm-buildroot-linux-gnueabihf_sdk-buildroot/bin/arm-buildroot-linux-gnueabihf-gcc-9.3.0
G++ Compiler path:
/arm-buildroot-linux-gnueabihf_sdk-buildroot/bin/arm-buildroot-linux-gnueabihf-g++
Sysroot path:
/arm-buildroot-linux-gnueabihf_sdk-buildroot/arm-buildroot-linux-gnueabihf/sysroot
Cmake path:
/arm-buildroot-linux-gnueabihf_sdk-buildroot/bin/cmake

Hi,

Did you try something like

cmake -DCMAKE_SYSTEM_NAME=Linux -DCMAKE_C_COMPILER=arm-buildroot-linux-gnueabihf-gcc \
         -DCMAKE_CXX_COMPILER=arm-buildroot-linux-gnueabihf-g++ \
         -DCMAKE_FIND_ROOT_PATH_MODE_PROGRAM=NEVER \
         -DCMAKE_FIND_ROOT_PATH_MODE_INCLUDE=ONLY \
         -DCMAKE_FIND_ROOT_PATH_MODE_LIBRARY=ONLY \
         -DCMAKE_FIND_ROOT_PATH_MODE_PACKAGE=ONLY .

It finished compiling but can't find most of the dependencies (the output doesn't work properly), I'm wondering if I should compile each dependency as a static library instead

It worked compiling with the buildroot kit at QT Creator! But it doesn't work properly either

It's seems to run, just your device doesnot support compress format, only nv12
