Dear I.MX Community,

I need to monitor USB-stick insertion in my attached c application using libudev & am using L2.6.35_10.12.01_ER_source for I.MX28

I am able to compile using gcc on ubuntu10.04 and it is "OK" but I cannot cross compile using  /opt/freescale/usr/local/gcc-4.4.4-glibc-2.11.1-multilib-1.0/arm-fsl-linux-gnueabi/arm-fsl-linux-gnueabi toolchain & facing the issue as shown below, could anybody please kindly do the needful in resolving the below issue as soon as possible

appusony@appusony-laptop:~/Desktop$ arm-none-linux-gnueabi-gcc libudev-test.c -o libudev-test -ludev

Sri, can you do the same compilation under LTIB's shell?

Hi,

what you need is to install  libudev-dev on your rootfs. Unfortunately, neither LTIB not Yocto has a recipe ready to be used to install the headers. The correct approach would be to create the .spec/.bb metadata for these building systems. Another approach, would be to install the package on your host, then move the files to rootfs. This latter approach is not good, but lets you move on.
