Squid cross compile - c++

Question

I've been trying to cross compile the Squid 3.5.7 on ARM Cortex A8 (Linux).
I downloaded it from http://www.squid-cache.org/Versions/v3/3.5/
I have arm-linux-gnueabi-gcc and arm-linux-gnueabi-g++.
tar -zxvf squid-3.5.7.tar.gz
cd squid-3.5.7
./configure --prefix=/usr/local/squid
make all
make install
Next I copy folders /usr/local/squid and ~/squid-3.5.7 to SD card.
When I try open ./squid -z from SD card on the board with ARM I have problem:
root#am335x:/# ls
bin etc lib mnt srv usr
boot findHelp linuxrc proc sys var
dev home media sbin tmp
root#am335x:/media/mmcblk0/squid/sbin# ls
squid
root#am335x:/media/mmcblk0/squid/sbin# ./squid -z
./squid: line 20: syntax error: ")" unexpected
root#am335x:/media/mmcblk0/squid/sbin# ./squid
./squid: line 20: syntax error: ")" unexpected
root#am335x:/media/mmcblk0/squid/sbin#
I don't know what to do :/

The binary which you have built is built for your PC architecture. To build squid for arm follow the below instructions.
The configure is trying to run a test which will fail if you are using a cross compiler so add a cache file to override those tests.
For example create a cache file squid.cache with the line shown below
squid_cv_gnu_atomics=no
Export the BUILDCXX variable required for compiling squid
export BUILDCXX=g++
Make sure you have exported the toolchain path to the path variable($PATH)
export PATH=<TOOLCHAIN_PATH>:$PATH
Then configure the squid by running the configure as shown below
./configure --host=arm-linux-gnueabi --cache-file=squid.cache --prefix=<install/dir>
Finally compile the squid by running make
make
Then install the binaries using make install
make install
