Cross Compilation Issue

[zahabshams]

Hi I am using your toolchain 4.1.15-1.2.0 for imx6. while compiling gpsd (gps daemon) using this toolchain i am getting error :

sysroots/pico-imx6/usr/include/gnu/stubs.h:7:29: fatal error: gnu/stubs-soft.h: No such file or directory compilation terminated. scons: *** [ais_json.os] Error 1 scons: building terminated because of errors.

Below is complete log of it.

Hello, zahabshams:

Thanks for your feedback. Could you try to replace the compiling instruction "arm-poky-linux-gnueabi-gcc" with "$CC"? Somebody had similar issue and solved it in this way: https://community.nxp.com/thread/350582#499896

Please follow the instructions in Section 6. "Create the toolchain for cross-compiling" in the following document: Yocto_2.0_BSP_Build_Guide.pdf

BR,

Richard

Hi Richard, Thanks for the response. Now I am landed in another issue with cross compilation. I am compiling gpsd for pico which uses scons build.

After compilation: My binary is pointing to - interpreter /lib/ld-linux.so.3 Whereas it should point to - interpreter /lib/ld-linux-armhf.so.3

Please find below flags: env.Append(LDFLAGS=['-mfloat-abi=hard'])

env.Append(CCFLAGS=['-march=armv7-a']) env.Append(CCFLAGS=['-mfloat-abi=hard']) env.Append(CCFLAGS=['-mfpu=neon']) env.Append(CCFLAGS=['-mtune=cortex-a9']) env.Append(CCFLAGS=['-D_XOPEN_SOURCE=700']) env.Append(CCFLAGS=['-mfloat-abi=hard'])

env.Append(CFLAGS=['-march=armv7-a']) env.Append(CFLAGS=['-mfloat-abi=hard']) env.Append(CFLAGS=['-mfpu=neon']) env.Append(CFLAGS=['-mtune=cortex-a9']) env.Append(CFLAGS=['-D_XOPEN_SOURCE=700']) env.Append(CFLAGS=['-mfloat-abi=hard'])

Hi Richard, Awaiting your response.

Hi, zahabshams:

I haven't run into this kind of problem. This might be a bug in Yocto.

Could you refer to the following link to create a symbolic link: https://lists.yoctoproject.org/pipermail/yocto/2017-April/035681.html

BTW, there is a recipe for gpsd in yocto. https://github.com/openembedded/meta-openembedded/tree/master/meta-oe/recipes-navigation/gpsd

It shouldn't need cross-compiling by yourself. And it should work by just enabling this package in local.conf in yocto.

BR,

Richard
