[SOLVED] cross compiling libopenfst makepkg error

Question

Hello there,
I am trying to cross compile openfst on my 64 bit arch setup since it is taking too long on my raspberry pi (which also happily runs arch). I thought I would be ok with the following makepkg to get me a binary package which I could transfer to my pi and then install with pacman-U:
# Maintainer: Christoph Drexler <chrdr at gmx dot at>
pkgname=openfst
pkgver=1.4.1
pkgrel=1
pkgdesc="Library for constructing, combining, optimizing, and searching weighted finite-state transducers (FSTs)"
arch=('i686' 'x86_64' 'armv6h')
url="http://www.openfst.org/"
license=('APACHE')
depends=('gcc-libs' 'glibc')
options=(!libtool)
source=("http://openfst.cs.nyu.edu/twiki/pub/FST/FstDownload/${pkgname}-${pkgver}.tar.gz")
md5sums=('ca8f1730b9b9b281e515611fa9ae23c0')
build() {
cd ${srcdir}/${pkgname}-${pkgver}
#export CXX=arm-linux-gnueabi-g++
#export CC=arm-linux-gnueabi-gcc
# Options according to http://openfst.cs.nyu.edu/twiki/bin/view/FST/ReadMe

LIBS="-ldl" ./configure $OPTIONS
make
package() {
cd ${srcdir}/${pkgname}-${pkgver}
make DESTDIR=${pkgdir} install
(basically adding the host and build option)
However, I get an error in the output:

Aborting...
the error being that the C++ compiler cannot create excecutables makes sense since they are not meant to be excecuted on x86_64 but for armv6h (cross compilation). I have checked with arm-linux-gnueabi-g++ and its excecutables I can run on my pi so this should be ok. I am guessing that I am either missing an option to disable the compiler check, or I should change the configure script and remove this check, but I cannot figure out how to do either...
//edit: I'm not sure this topic is in the right place btw, maybe it should be in scripting...

Answer 1

that seems to do the trick, I'm not gonna test it since my pi just finished compiling it locally (which took 12+hours or so), but the compile seems to work since they are not excecutable on 64 bit, so pkgbuild for raspi cross compilation using makepkg -s:

I will check soon I hope , for now will mark it as solved.
