Hi,
I am currently building an linux system for arm board. I am stuck with
udev. So can you help me with some commands to compile udev with cross
compilation?
Thanks for your time
I am cross compiling udev, but not for the ARM.
The only trouble that I have encountered when cross compiling version
151 is with the configure scripts determination of the pci.ids file
location. This is caused by autoconf's AC_CHECK_FILES macro generating
an error when cross compiling. However, this can be worked around by setting
ac_cv_file__usr_share_pci_ids='no'
ac_cv_file__usr_share_hwdata_pci_ids='no'
ac_cv_file__usr_share_misc_pci_ids='no'
in the build system's environment before running configure and setting
the configure script's --with-pci-ids-path argument.
I have had this work around for so long that I have not given it much
thought. However, it is relatively easy to fix the configure script so
that it only attempting to determine the pci.ids file location when
--with-pci-ids-path is not set. Therefore, I have created and attached a
patch that should do this. Of course, after applying, you would need to
rerun autoconf or autoreconf.
