How to compile openssl 1.0.2f on Beaglebone Black?

Question

Currently, I use command below to compile openssl 1.0.2f from openssl package:

$ tar xzf openssl-1.0.2e.tar.gz
$ cd openssl-1.0.2e
$export PREFIX={PREFIX}
$./Con

How to compile openssl 1.0.2f on Beaglebone Black?

I believe you want the linux-armv4 target.

$ ./Configure LIST | grep -i arm
android-armeabi
linux-arm64ilp32
linux-armv4

Also see Compilation and Installation on the OpenSSL wiki.

Its probably easiest to follow Leśny's advice and run ./config. config tries to guess at the target. If the guess is wrong, then use ./Configure with the triplet:

$ wget https://www.openssl.org/source/openssl-1.0.2g.tar.gz
...
$ tar xzf openssl-1.0.2g.tar.gz
...
$ cd openssl-1.0.2g

And then (notice linux-armv4):

$ ./config shared no-ssl2 no-ssl3 no-comp -DOPENSSL_NO_HEARTBEATS                     
Operating system: armv7l-whatever-linux2

You may need to fallback to something like this:

$./Configure linux-armv4 shared no-ssl2 no-ssl3 no-comp -DOPENSSL_NO_HEARTBEATS
...
$ make depend
...
$ make clean
...
$ make

For completeness, I was working from a BeagleBone Black using a Debian console image from December, 2015 (I needed the small, 2GB footprint so storage was available for other things):

$ uname -a
Linux beaglebone 4.1.15-ti-rt-r40 #1 SMP PREEMPT RT Thu Jan 7 23:32:08 UTC 2016 armv7l GNU/Linux
