[16:28] <angs> is it enough to install "apt-get install build-essential" to have the toolchains to cross-compile C code for beagleboard-Xm?
[16:28] <angs> do I need to install apt-get install gcc-4.7-arm-linux-gnueabihf ?
[16:43] <angs> I am using gcc-arm-linux-gnueabihf to cross compile, what path do I need to link for libusb-1.0?
[16:50] <prpplague> angs: where every you have the libusb libraries compiled for arm
[16:51] <prpplague> angs: not your local ones that are most likely compiled for x86
[16:52] <angs> I used to link lusb-1.0 on eclipse as /usr/include/libusb-1.0 on "C/c++ general> paths and symbols >library paths" and it was working fine to build the code on my desktop. To cross-compile, I added "/usr/arm-linux-gnueabihf/lib" before "/usr/include/libusb-1.0"", now I get "cannot find -lusb-1.0" error when I build the code.
[16:52] <angs> should I copy the libusb-1.0 directory under /usr/arm-linux-gnueabihf/lib
[16:53] <angs> or do I suppose to install libusb-1.0 for arm?
[17:00] <angs> prpplague: how can I add libusb on arm's gcc ?
[17:26] <angs> can anyone tell me how do I suppose to use libusb on ubuntu-arm?
[17:27] <prpplague> angs: did you add libusb files that were complied for arm in the directory - /usr/arm-linux-gnueabihf/lib ?
[17:34] <angs> prpplague: I copied libusb* files from /usr/lib to /usr/arm-linux-gnueabihf/lib and libusb-1.0 from /usr/include to /usr/arm-linux-gnueabihf/include however I still have the same problem
[17:34] <angs> I get this error when I build the program "skipping incompatible /usr/arm-linux-gnueabihf/lib/libusb-1.0.a when searching for -lusb-1.0"
[17:35] <prpplague> angs: the libusb files in /usr/lib on your host pc are for x86
[17:35] <prpplague> angs: they are not for arm
[17:35] <angs> where can I download libusb files for arm?
[17:35] <prpplague> angs: i would assume there is a ubuntu package you can get, however i alway build them myself
[17:37] <angs> prpplague: do you have built libusb files on your machine that you can share?
[17:37] <prpplague> angs: easier for you to do it yourself of find the ubuntu packages
[17:37] <prpplague> angs: what hardware platform are you using?
[17:38] <angs> prpplague: I am using beagleboard-Xm. I am a beginner linux user, I do not know how to build package
[17:39] <prpplague> angs: then download the ubuntu pre-built package
[17:42] <angs> I already installed libusb-1.0 and libusb-dev, do you know is there any portal to search pre-built package for ubuntu arm?
[17:43] <prpplague> https://launchpad.net/ubuntu/precise/+package/libusb-dev
[17:43] <prpplague> just one example
[17:43] <prpplague> angs: you installed the libusb for you host machine which is x86
[17:43] <prpplague> not the arm ones
[17:45] <angs> prpplague: thank you very much, I am installing the package for beagleboard now
[17:45] <prpplague> angs: google is your friend
[17:46] <angs> right, I was using the wrong keyword to search on google. thank you very much for your help
[17:56] <angs> prpplague: I have one last question. dpkg -i libusb-dev_0.1.12-20_armhf.deb outputs "package architecture (armhf) does not match system (i386)" error. Do you know if it is possible to install that package under /usr/arm-linux-gnueabihf directory?
[17:56] <prpplague> angs: yea, there should also be a cross compile package somewhere
[17:59] <angs> do you know name of the package?
[18:00] <prpplague> angs: no, like i said, i normally build everything from source
[18:00] <prpplague> angs: i am certain there is a howto on the ubuntu wiki pages for what you want to do
[18:00] <prpplague> angs: please check there
[18:01] <angs> prpplague: thank you I will check there
