Date: 24/12/2015 Tags: scribe linux	I think for the first time ever? There is a simultaneous release of Scribe on 3 different platforms: Windows, Mac AND Linux. The new v2.1.3 build is tri-platform. The Linux (x64) build is a GTK2 app and runs ok on Ubuntu and Arch. Well that's all I've tested at this point. It also runs on a Raspberry Pi 2 although it's a little slow. I know because I got bored and tried building it while working on some MC2 stuff. Links to the i.Scribe builds: Win32 Mac32 Linux64

Portable OpenSSL for Linux
Date: 21/12/2015 Tags: shared-object linux openssl scribe	A year ago I worked out how to make a portable build of OpenSSL for Mac. And now with the imminent release of the Linux build of Scribe I need to do the same with the Linux build of OpenSSL. After downloading and unpacking OpenSSL I configured it with: ./config shared -DPURIFY The reason for adding the -DPURIFY #define is to suppress valgrind errors related to uninitialized memory usage. Once that is built I had a look at the shared object paths with ldd: matthew@ubuntu:~/Downloads/openssl$ ldd ./libssl.so.1.0.0 linux-vdso.so.1 => (0x00007ffc0e197000) libcrypto.so.1.0.0 => /lib/x86_64-linux-gnu/libcrypto.so.1.0.0 (0x00007f5c5ab6c000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f5c5a7a7000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f5c5a5a3000) /lib64/ld-linux-x86-64.so.2 (0x00007f5c5b1c1000) So it's not portable yet. I initially tried using the chrpath command but it can only modify existing RPATH records. My binary doesn't have any RPATH yet. So that didn't work. The next thing I tried was the patchelf command from here: http://nixos.org/releases/patchelf/patchelf-0.8/ After building and installing I issued this command in the OpenSSL folder: patchelf --set-rpath '$ORIGIN' ./libssl.so.1.0.0 Now to check if libssl pulls in the local libcrypto: matthew@ubuntu:~/Downloads/openssl$ ldd ./libssl.so.1.0.0 linux-vdso.so.1 => (0x00007ffcdce86000) libcrypto.so.1.0.0 => /home/matthew/Code/Scribe/trunk/./libcrypto.so.1.0.0 (0x00007f39b99d8000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f39b9613000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f39b940f000) /lib64/ld-linux-x86-64.so.2 (0x00007f39ba0a5000) Yes! Now this build can be installed in the same folder as the Scribe binary and Scribe will use it without interfering with the system OpenSSL which is often out of date, or not built with -DPURIFY or missing.

Portable OpenSSL for Linux

A year ago I worked out how to make a portable build of OpenSSL for Mac. And now with the imminent release of the Linux build of Scribe I need to do the same with the Linux build of OpenSSL.

After downloading and unpacking OpenSSL I configured it with:

./config shared -DPURIFY

The reason for adding the -DPURIFY #define is to suppress valgrind errors related to uninitialized memory usage.

Once that is built I had a look at the shared object paths with ldd:

matthew@ubuntu:~/Downloads/openssl$ ldd ./libssl.so.1.0.0 
	linux-vdso.so.1 =>  (0x00007ffc0e197000)
	libcrypto.so.1.0.0 => /lib/x86_64-linux-gnu/libcrypto.so.1.0.0 (0x00007f5c5ab6c000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f5c5a7a7000)
	libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f5c5a5a3000)
	/lib64/ld-linux-x86-64.so.2 (0x00007f5c5b1c1000)

So it's not portable yet. I initially tried using the chrpath command but it can only modify existing RPATH records. My binary doesn't have any RPATH yet. So that didn't work. The next thing I tried was the patchelf command from here:

http://nixos.org/releases/patchelf/patchelf-0.8/

After building and installing I issued this command in the OpenSSL folder:

patchelf --set-rpath '$ORIGIN' ./libssl.so.1.0.0

Now to check if libssl pulls in the local libcrypto:

matthew@ubuntu:~/Downloads/openssl$ ldd ./libssl.so.1.0.0 
	linux-vdso.so.1 =>  (0x00007ffcdce86000)
	libcrypto.so.1.0.0 => /home/matthew/Code/Scribe/trunk/./libcrypto.so.1.0.0 (0x00007f39b99d8000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f39b9613000)
	libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f39b940f000)
	/lib64/ld-linux-x86-64.so.2 (0x00007f39ba0a5000)

Yes! Now this build can be installed in the same folder as the Scribe binary and Scribe will use it without interfering with the system OpenSSL which is often out of date, or not built with -DPURIFY or missing.
