Hello I tried to compile a Go program on ARM with dynamic link.
Why dynamic? Because the libs I use in C are proprietary and the
constructor does not want to compile in static.
I build like this:
export PATH=$PATH:/home/ronron/aml_npu_sdk_6.4.3/toolchains/
export CGO_ENABLED=1
export LIB_DIR=$TOOLCHAIN/../aarch64-linux-gnu/libc/lib
export ROOTSDK=/home/ronron/aml_npu_sdk_6.4.3/
export
VIVANTE_SDK_INC="/home/ronron/aml_npu_sdk_6.4.3/linux_sdk/linux_sdk_6.4.2.1/build/sdk/include"
export
AQROOT="/home/ronron/aml_npu_sdk_6.4.3/linux_sdk/linux_sdk_6.4.3/build"
export OVXLIB_DIR="$ROOTSDK/linux_sdk/linux_sdk_6.4.3/acuity-ovxlib-dev"
export
OPENCV_ROOT="/home/ronron/aml_npu_sdk_6.4.3/linux_sdk/linux_sdk_6.4.0.10/build/sdk/opencv3-3.4.3"
export CGO_CFLAGS="-I$VIVANTE_SDK_INC -I$VIVANTE_SDK_INC/HAL
-I$AQROOT/sdk/inc -I./ -I$OVXLIB_DIR/include/utils
-I$OVXLIB_DIR/include/client -I$OVXLIB_DIR/include/ops
-I$OVXLIB_DIR/include -I$OVXLIB_DIR/third-party/jpeg-9b -DgcdSTATIC_LINK=0"
export CGO_CPPFLAGS="-I$VIVANTE_SDK_INC -I$VIVANTE_SDK_INC/HAL
-I$AQROOT/sdk/inc -I./ -I$OVXLIB_DIR/include/utils
-I$OVXLIB_DIR/include/client -I$OVXLIB_DIR/include/ops
-I$OVXLIB_DIR/include -I$OVXLIB_DIR/third-party/jpeg-9b -DgcdSTATIC_LINK=0"
export CGO_LDFLAGS=" -lpthread -ldl -L$OVXLIB_DIR/lib -L $OPENCV_ROOT/lib
-L$AQROOT/sdk/lib
-L/home/ronron/aml_npu_sdk_6.4.3/linux_sdk/linux_sdk_6.4.3/build/sdk/drivers_32
-ljpeg -lovxlib -L$VIVANTE_SDK_LIB -lOpenVX -lovxlib -shared
-lopencv_imgproc -lopencv_core -lopencv_videoio -lopencv_imgcodecs
-lopencv_highgui -lz -lm"
go build -linkshared -a
when I run program:
rron:~/test_go$ strace ./test_go te
execve("./test_go", ["./test_go", "te"], 0x7ff746a528 /* 27 vars */) = 0
--- SIGILL {si_signo=SIGILL, si_code=ILL_ILLOPC, si_addr=0x7fadb45000} ---
+++ killed by SIGILL +++
Illegal instruction
I don't make crosscompiling and I don't see my error :( one idea ?
