I'm in the process of trying to get net-snmp up on an ARM processor using the snapgear toolchain, and I'm having a similar problem to the one quoted here [a search of the problem parameters turned up this old posting, so I'm tacking on to it].
I've been able to narrow my problem down to the fact that the snapgear toolchain comes with two different flavors of "net/route.h" /usr/local/arm-linux/sys-include/net/route.h /usr/local/arm-linux/include/net/route.h The first one is the linux kernel version, which contains: #ifndef __KERNEL__ #warning This file is not supposed to be used outside of kernel. #endif The second is the libc version which is what should be used. Unfortunately, for whatever reason the ARM toolchain defaults to using the sys-include version, even if I have "-I /usr/local/arm-linux/include" in my CFLAGS and CPPFLAGS. The netsnmp configure script then fails the test for net/route.h since the #warning was encountered. My current solution is to add "-isystem /usr/local/arm-linux/include" to my CFLAGS and CPPFLAGS, which seems to work, but I'm not sure this is the most correct solution. So I'm curious if anyone has a different solution to this problem (or can suggest an alternate forum to direct my query).

Subject: CrossCompiling Net-Snmp for Arm9 Hi all I'm looking for some information in crosscompiling NetSnmp for Arm I've seen that there is already a topic about this subject but i haven't found any response in it Actually, i'm using prebuild toolchain 2.95.3 and 3.0 and i've some problems in building configure step seems to run well but not "make" step i've tried two command lines: [EMAIL
