Cross compile crash. RPi. #49

Open ivlevdenis opened 8 years ago

ivlevdenis commented 8 years ago

I'm testing cross compile this lib for Raspberry Pi 2.

  1. Mount RPi rootfs to /mnt/rasp-pi-rootfs/. Create symlink in /usr/local to /mnt/rasp-pi-rootfs/usr/local/QtDIR.
  2. Create simple test bin with cargo new hello --bin and add qmlrs to dependencies.
  3. Add target to ~/.cargo/config 
[target.armv7-unknown-linux-gnueabihf]
linker = "/mnt/rasp-pi-rootfs/usr/bin/arm-linux-gnueabihf-gcc"
  1. First run cargo build --target=armv7-unknown-linux-gnueabihf for fetch dependencies.
  2. Add 
set(CMAKE_SYSTEM_NAME Linux)
set(CMAKE_SYSROOT /mnt/rasp-pi-rootfs)
set(CMAKE_C_COMPILER /home/di-erz/projects/images/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gcc)
set(CMAKE_CXX_COMPILER /home/di-erz/projects/images/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++)
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_PACKAGE ONLY)

to CMakeLists.txt to qmlrs-0.1.1/ext/libqmlrswrapper. Then build static libqmlrswrapper

$ cd qmlrs-0.1.1/ext/libqmlrswrapper/build

$ PATH=$PATH:/mnt/rasp-pi-rootfs/usr/local/Qt-rasp2-5.7.0 \
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/mnt/rasp-pi-rootfs/usr/local/Qt-rasp2-5.7.0/lib \
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/mnt/rasp-pi-rootfs/usr/local/Qt-rasp2-5.7.0/lib/pkgconfig/ \
CMAKE_SYSROOT=/mnt/rasp-pi-rootfs/ \
CMAKE_CXX_COMPILER=/mnt/rasp-pi-rootfs/usr/bin/arm-linux-gnueabihf-cpp \
CMAKE_C_COMPILER=/mnt/rasp-pi-rootfs/usr/bin/arm-linux-gnueabihf-gcc \
cmake ../

$ make
  1. Return to test project dir, clean, and rebuild.
$ cd projects/hello

$ CMAKE_SYSROOT=/mnt/rasp-pi-rootfs \
PATH=/mnt/rasp-pi-rootfs/usr/local/Qt-rasp2-5.7.0:$PATH \
PKG_CONFIG_PATH=/mnt/rasp-pi-rootfs/usr/local/Qt-rasp2-5.7.0/lib/pkgconfig/ \
PKG_CONFIG_ALLOW_CROSS=1 \
cargo build --target=armv7-unknown-linux-gnueabihf --verbose

Cargo exit with 101 error code.

I would be glad of any idea!
