[Scons-dev] Issue 2869 - Versioned shared libraries

[Managan, Rob]

Russel,

I am about to add a test to that repo. I have attached it as a zip file.

Try that and you will see what links are already built into the system I
have created.
For OSX you get the version number added to the real file name and a link
(w/o version number) to that file.

It would be great to get feedback from someone really using it for a real
application and can point out things that did not occur to me!

While the example does not do this, I recommend that you create the
environment with SHLIBVERSION, instead of defining it on the env.SharedLib
command which just defines that for the build and not the install step.

On OSX you get:

scons: Reading SConscript files ...
SHLIBVERSION '' does not match the version # '2.5.4' in the filename,
proceeding based on file name
scons: done reading SConscript files.
scons: Building targets ...
gcc -o test.os -c -fPIC test.c
gcc -o libtest.2.5.4.dylib -dynamiclib -current_version 2.5.4
-compatibility_version 2.5.4 -undefined dynamic_lookup test.os
Install file: "libtest.2.5.4.dylib" as
"/Users/managan1/My_Downloads/install_test/libtest.2.5.4.dylib"
SHLIBVERSION '' does not match the version # '2.5.4' in the filename,
proceeding based on file name
scons: done building targets.

On posix systems the version number comes after the .so instead of before
the .dylib and there are two additional symlinks, lib test.so.2, lib
test.so.2.5,...
