I need netmap for ARM platform

[punkofnewsociety]

Hello , I`m trying to run make, having this output.
I need netmap for ARM platform

Anyone can help ?

Hi,
you can try these steps:

cd /home/vladislav/Fobos-Plug-HSD/netmap/LINUX
make distclean
./configure --kernel-dir=/home/vladislav/Fobos-Plug-HSD/linux-3.1.1 --kernel-opts="ARCH=arm CROSS_COMPILE=/home/vladislav/Fobos-Plug-HSD/arm-2009q3/bin/arm-none-eabi-" --cc=/home/vladislav/Fobos-Plug-HSD/arm-2009q3/bin/arm-none-eabi-cc --ld=/home/vladislav/Fobos-Plug-HSD/arm-2009q3/bin/arm-none-eabi-ld
make
make apps

Cheers,
Stefano

Well the problem is that my pre-built kernel seems to be compiled correctly

`
and finally i recieve those errors which i meentioned in my prev message.
probably when errors such as
function takes 4 arguments instead of 3
may occur when during configuring netmap do not changes these functions with suitable direclty from the library , and using standart functions from my pre-built kernel .
i think probably of that error unsupported platform may occur

maybe you know what can help in this situation ?

[punkofnewsociety]

Where can i figure out which version of kernel was used to build netmap , cause in my device there is 3,1,1 version and my head-chief says that this is very old version and probably i need to rewrite sources of netmap-library according to the version of kerlnel 3.1.1 .
Any feedback will be useful

[vmaffione]

@punkofnewsociety could you try again with the latest code? The build system has changed.

[punkofnewsociety]

not think it will be soon, but i will try to check it.

[ykondrashyn]

@punkofnewsociety have you managed resolve this issue?

[punkofnewsociety]

hi. @ykondrashyn it was very long time ago. It seems to me that i have managed that by testing some ifdef/ifndef macroses. Just is one macros cannot be included by mistake, so then some errors like undefined reference might occur later. Excuse me if im mistaken , was too much time ago ^_^

[ykondrashyn]

Thank you, the issue was revealed during building of netxtreme2-7.12.10 drivers, namely while building bnx2 driver.
So, I've taken bnx2x, which builds correctly, from 7.12.10 and used old bnx2 from 7.10.14.
Hope it will help someone

hi. trying to build netmap module for android. compile is ok but during linking i m getting following error.

prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9/bin/aarch64-linux-android-ld: no input files
make[2]: *** [/home/netmap/netmap-master/netmap.o] Error 1
make[1]: *** [_module_/home/netmap/netmap-master] Error 2
make[1]: Leaving directory `/home/kernel/linux-4.1'
make: *** [netmap.ko] Error 2

the CROSS_COMPILE and other paths are set properly. the .o generated properly for arm architecture.
for ex:
netmap_mem2.o: ELF 64-bit LSB relocatable, ARM aarch64, version 1 (SYSV), not stripped

any idea what might be the issue.

thanks.

hi,

was able to solve this by manually executing the linking steps. (after make has compiled individual files)
