Crosscompiling for BananaPro failed

[Spanni26]

Hello,

I try to cross compile the Peak USB for a BananaPro board (http://www.lemaker.org/product-bananapro-index.html).
I've downloaded a toolchain, changed the settings in the peak Makefile (export ARCH=arm, export CROSS_COMPILE=/opt/cross/bin/arm-linux-gnueabi-, KERNEL_LOCATION = "/root/lemaker-bsp/build/sun7i_defconfig-linux/").

The driver is compiling fine, but I*m failing at the lib and the test directory:

Code: Select all

make[1]: Entering directory '/root/peak-linux-driver-7.15.2/lib'
/opt/cross/bin/arm-linux-gnueabi-gcc src/libpcan.c -DNO_RT -I. -I../driver -fPIC -shared -O2 -Wall  -Wl,-soname,libpcan.so.0 -lc  -o libpcan.so.0.6

Makefile:120: recipe for target 'receivetest' failed
make[1]: *** [receivetest] Error 1
make[1]: Leaving directory '/root/peak-linux-driver-7.15.2/test'

I'm compiling at a opensuse 13.2
stdio.h and stdlib.h are both at /usr/include so I don't have a idea why it is failing here.

Any hints?

Regards

Hi Daniel,

Since you're cross-compiling, "/usr/incldue/stdio.h" should'nt obvioulsy be the right file to include.

To cross-compile the pcan library , you have to edit the related "lib/Makefile" and define the CC variable with the right cross-compiler:

Code: Select all

 #****************************************************************************
 #
 # Makefile - Makefile for the shared library libpcan.so.x.x
 #
 # $Id: Makefile 517 2007-07-09 09:40:42Z edouard $
 #
 #****************************************************************************

+CC := arm-linux-gnueabi-

 SRC     = src

Same change should be done for the test applications (as well as for yours) in "test/Makefile":

Code: Select all

 #****************************************************************************
 #
 # Makefile - Makefile for receivetest and transmittest programs
 #
 # $Id: Makefile 616 2010-02-14 22:41:17Z khitschler $
 #
 #****************************************************************************

+CC := arm-linux-gnueabi-

 SRC = src

Finally, depending on the toolchain, you might also have to define some (other) LDFLAGS...
