Compilation issue for LEDE openwrt FRR 5.0.

[lion24]

Hi everyone !

I'm trying to compile FRR for my Linksys WRT1200AC at home. And autoconf is not able to set correct build parameter for cross-compilation.. It fails will the following error:

make[2]: Entering directory '/home/lionel/workspace/openwrt/feeds/routing/frr'

The following FRR package I'm trying to compile is available on my github repository here: https://github.com/lion24/frr-openwrt

I know this is an issue solved in the past in #958 but I'm not able to find my way in. I tried the suggestion but none of them works.. And it still tries to run my own gcc compiler, even if I overwrite --build="$(GNU_HOST_NAME)" in the `CONFIGURE_ARGS´

checking build system type... x86_64-redhat-linux-gnu

Thanks for the support !

Hey - just wanted to say I've seen this issue and want to nail down our process for cross compiling (and document it!), I just haven't gotten around to it yet. Did you manage to get it built?

[cfra]

It is giving an error message detailing what to do:

configure: error: cross-compilation is only possible with builddir separate from srcdir. create a separate directory and run as .../path-to-frr/configure.

So to address this, when you are in the frr dir, run:

mkdir ../frr-build
cd ../frr-build
../frr/configure

You might run into other cross-compile issues, but this should address the error message you are seeing
