The solution here was to swap Python libraries from requests[security] to pycurl. Also rather than using Pip to install them, there's already a precompiled package to be applied using OPKG

Uurgh, managed to get OpenSSL to compile but now seem to have lost the ability to create a libffi shared library. Was previously using the linino image but when reflashed to fix problem with OpenSSL, I reverted to the standard Arduino image..

So there's two issues with installing OpenSSL, The first is that it needs PERL to configure it. That seems to be available over at http://downloads.openwrt.org/snapshots/trunk/ar71xx/generic/packages/packages/ the second issue is that it OPKG depends on it, so removing it will break OPKG until I've got it back on again...

Having messed up that second point and re-installed my image, it would appear that Perl is also available on the main Arduino repository.

Perl also needed a bunch of modules. There were modules that I could download but they did not include things needed by OpenSSL. So I downloaded the 5.10.1 version of perl from http://www.cpan.org/src/README.html and copied on on Exporter.pm, vars.pm,warnings.pm, warnings\register.pm, strict.pm

You can test this with

perl -e 'use strict; print "ok"'

I also reinstall Make

opkg install make

I then ran through the configure steps

http://wiki.openssl.org/index.php/Compilation_and_Installation

I had to re-add some of the execute x permissions to ./Config Utils/*.* and as I'd unzipped on a Windows machine and the scripts had lost those.

make depend

ran successfully

make all

ran successfully

make install

Seems to have copied on the .so files but it's reported the following error....

gcc -I.. -I../include -DOPENSSL_THREADS -D_REENTRANT -DDSO_DLFCN -DHAVE_DLFCN_H -Wa,--noexecstack -O3 -fomit-frame-pointer -Wall -c -o md2test.o md2test.c
md2test.c:1:10: error: expected '=', ',', ';', 'asm' or '__attribute__' before '.' token
dummytest.c
^

Need to review make all and see if we can build without tests, demos etc.

Ok, so the above manual patching of the libffi source seems to have allowed me to build libffi and install it.

However it's installed to /usr/local/ rather than /usr/ I've no idea what that means but I moved them over to the same folders as the others.

The /usr Versus /usr/local Debate

I've re-read the manual and you can fix that with an option on configure.

You may want to tell configure where to install the libffi library and

header files. To do that, use the --prefix configure switch. Libffi

will install under /usr/local by default.

Also this whole build process did not copy on the headers so I've copied those in from /mnt/sda1/libffi-3.0.13/mips-unknown-linux-gnu/include to /usr/include/libffi

The error of the day is now....

"To fix this problem, you have to install OpenSSL development package, which is available in standard repositories of all modern Linux distributions."

Except for Arduino...

So I'm guessing I need to repeat my steps with ffi but with openssl...

There's a couple of references to this issue

http://lists.gnu.org/archive/html/discuss-gnustep/2010-01/msg00035.html

I tried copying the install-sh into my mips-unknown-linum-gnu folder and that does seem to have moved me onto a different error ldconfig: not found which I'm guessing as a missing dependency. I've logged an error on github for this

This time it does seem to have installed libffi but there's one line "ldconfig: /usr/local/lib/libffi.so.6 is not a symlink" which might still be an error

Running configure for ffi gave me an error about grep which I'd seen when doing the attempt at Python2.7.9

[embed:dc8ab71f-3b98-42d9-b0f6-e21e02a0f8e2:3ef06e6b-9b7d-4651-b12d-db8be7f5e991:type=text&text=checking+for+grep+that+handles+long+lines+and+-e...+configure%3A+error%3A+no+acceptable+grep+could+be+found+in+%2Fbin%3A%2Fsbin%3A%2Fusr%2Fbin%3A%2Fusr%2Fsbin%3A%2Fusr%2Fxpg4%2Fbin]

I found a fix for grep but then realised I'd not got "make", again I had see then when doing the Python build (which is when I was on the Linino distribution) so I got it from there.

RE: Enchanted Objects Design Challenge - The snake, the troll and the fighting dwarves

After several hours of searching I gave up. As I'd spotted that option in the newer GCC headers I thought I'd try installing a newer GCC.

I found one over at OpenWRT

Ref: http://www.dd-wrt.com/phpBB2/viewtopic.php?p=919720
http://noblepepper.com/wp/blog/2014/10/22/gcc-g-on-an-arduino-yun/

I had to remove the old version and install the newer one. This is a bit of a risky process according to opkg as I had to remove an "essential" package to replace it with the newer one.

[embed:dc8ab71f-3b98-42d9-b0f6-e21e02a0f8e2:3ef06e6b-9b7d-4651-b12d-db8be7f5e991:type=text&text=opkg+remove+yun-gcc%0Acd+%2Fmnt%2Fsda1%2F%0Awget+http%3A%2F%2Fdownloads.openwrt.org%2Fsnapshots%2Ftrunk%2Far71xx%2Fgeneric%2Fpackages%2Fpackages%2Fgcc_4.8.3-1_ar71xx.ipk%0Awget+http%3A%2F%2Fdownloads.openwrt.org%2Fbarrier_breaker%2F14.07%2Far71xx%2Fgeneric%2Fpackages%2Fbase%2Flibstdcpp_4.8-linaro-1_ar71xx.ipk%0Aopkg+--force-remove+--force-removal-of-essential-packages+remove+libstdcpp%0Aopkg+--force-remove+remove+gcc%0Aopkg+install+libstdcpp_4.8-linaro-1_ar71xx.ipk%0Aopkg+install+gcc_4.8.3-1_ar71xx.ipk]

Now the pip install requests[security] gave me an error about not finding Python.h. The Linux forums suggested I needed to install the Python-dev package. Something that does not seem to exist for the Yun. So I downloaded 2.7.3 Python and extracted files using tar -xz -f Python-2.7.3.tgz. Next I copied Python.h to /usr/include/python2.7

That produced an other error about patchlevel.h so I copied the whole of the /include folder into /usr/include/python2.7.

My latest error is "fatal error: ffi.h: No such file or directory", I've got the ffi source but there's no ffi.h header, I'm guessing that the configure script will build one of those. Let's hope I have more luck with that than the configure script for Python 2.7.9 which kept telling me that my int has size 0.

Running "opkg install binutils" got rid of my "as" error. Now just have the -fhonour-copts issue, there's no mention of that option in the cffi package.

I just can't work out where that option might be set.

There also seems to be headers for both 4.6.2 and 4.6.3 but I can't see how you'd change that. The 4.6.3 headers do actually mention -fhonor-copts in options.h

There's nothing in ENV either than mentions this.

Can anyone give me a point in the right direction?

Just realised "as" is the GNU assembler, that seems to be in the bintools package, I'll check if installing that removes the errors.

Given my difficulty getting Python to compile I though I'd try a smaller challenge. The "pip install requests[security]" needs a compiler to install so I've checked that. It's currently erroring with

pip install requests[security] works nicely on my dev machine.

Compiling Python 2.7.9 is complaining on the Yun. Looks like I need to decipher the configuration shell script and/or the header files, neither look particularly appealing. Here's my configure.log.

I tried installing the security fixes with

pip install requests[security]

that gave me errors about not having a gcc so I've installed that too. Then I got a new error about not having the Python.h file. I tried to install the package for that but it was not listed.

So I'm currently going down the approach of compiling 2.7.9 from scratch but it the snake is fighting me all the way!
