Well, theoretically, the same way you would compile any other program
for that arch. I have no idea if there's anything that will break for
such a compile, but if there is, patches are very welcome.
However, I'm not sure how useful xdp-loader actually is on MIPS; the
kernel support for BPF on that arch is quite limited. Haven't played
with it myself, though, so YMMV.

Thank you very much for your answers. 1、I see lines 60-71 of the configure script file:
2、then I modify it to:
3、then ./configure,below is output:
4、then I make

Thank you very much for your answers.
I try to fix it,it's all steps I do,hope you can give me some advise, thanks!
1、I see lines 60-71 of the configure script file:
` : ${PKG_CONFIG:=pkg-config}
: ${CC=gcc}
: ${LD=ld}
: ${OBJCOPY=objcopy}
: ${CLANG=clang}
: ${LLC=llc}
: ${M4=m4}
: ${EMACS=emacs}
: ${BPFTOOL=bpftool}
: ${READELF=readelf}
: ${ARCH_INCLUDES=}
: ${ARCH_NAME=}`
2、then I modify it to:
` : ${PKG_CONFIG:=pkg-config}
: ${CC=mips64el-linux-gcc}
: ${LD=mips64el-linux-ld}
: ${OBJCOPY=mips64el-linux-objcopy}
: ${CLANG=clang}
: ${LLC=llc}
: ${M4=m4}
: ${EMACS=emacs}
: ${BPFTOOL=bpftool}
: ${READELF=mips64el-linux-readelf}
: ${ARCH_INCLUDES=}
: ${ARCH_NAME=mips}`
You don't need to edit the file, you can just set these when running
configure:
CC=mips64el-linux-gcc LD=mips64el-linux-ld OBJCOPY=mips64el-linux-objcopy READELF=mips64el-linux-readelf ARCH_NAME=mips ./configure
(or export all of them before running configure).
3、then ./configure,below is output:
***@***.***:~/xdp-tools# ./configure

4、then I make

Well, it looks like you are missing some kernel header files? This is a
cross-compile build environment issue that I can't really help you with,
I'm afraid.

thank you so much for your answer,thanks you for telling me the way to assign the MACRO.
I want to know which parameter need to assign, |

thank you so much for your answer,thanks you for telling me the way to assign the MACRO.
Now I have a question:
: ${PKG_CONFIG:=pkg-config}
: ${CC=mips64el-linux-gcc}
: ${LD=mips64el-linux-ld}
: ${OBJCOPY=mips64el-linux-objcopy}
: ${CLANG=clang}
: ${LLC=llc}
: ${M4=m4}
: ${EMACS=emacs}
: ${BPFTOOL=bpftool}
: ${READELF=mips64el-linux-readelf}
: ${ARCH_INCLUDES=}
: ${ARCH_NAME=mips}`
I want to know which parameter need to assign,
now I have already assigned 4,I don’t know whether it‘s enough.
and if I want to build for mips arch,
what value should assigned for INCLUDES and ARCH_NAME ?
No idea. I don't actually have much experience cross-compiling for MIPS,
so I'm afraid you'll have to find an actual expert to answer this :)

OK,I see, Thank you so much for answer my questions! |
