You need to also use the host LD when linking the sandesh IDL compiler. You can’t use the cross-compilation linker (ppc) to link x86 object files.

I tried to execute the /build/bin/sandesh it is not executed.It is in powerpc executable. How can i build the sandesh to x86 executable while building the targets with the sandesh targets should be executable on powerPC. You will have to define scons rules so that the sandesh compiler is built with the host compiler rather than with the cross compiler. Often build systems have the notion of a HOST_CC environment variable. You can modify the scons rules such that when building the sandesh compiler HOST_CC takes precedence over CC… the env.Alias targets defined in controller/src/vnsw/agent/contrail. If i remember correctly this is “scons agent:contrail-vrouter-agent" With this command it is showing errors follows Do not know how to make File target `agent:contrail-vrouter-agent' I ran this command on the home directory where the sconstruct file is present I tried the following command also scons controller/src/vnsw/agent/contrail:contrail-vrouter-agent This also not working Can you explain some more detail about how to compile the source code for contrail-vrouter-agent. ________________________________ From: [email protected]<mailto:[email protected]> To: [email protected]<mailto:[email protected]> CC: [email protected]<mailto:[email protected]> Subject: Re: [opencontrail-dev] vrouter user space agent cross compilation Date: Mon, 24 Aug 2015 16:26:39 +0000 Dinesh, On Aug 18, 2015, at 9:33 PM, Dineshkumar parameswaran <[email protected]<mailto:[email protected]>> wrote: Hi all, I need to cross compile the vrouter data plane component and user space component to powerpc platform.

Can you try to execute “build/bin/sandesh” ? You can look at what the build rules are in tools/build/rules.py for SandeshCBuilder or use "scons -v” and try to figure out why this step is failing.
