Hello Tim, we just tried the trunk. It's better but there are still multiple problems: - LDFLAGS is not used when you link the executables (it's only used when you link libregfi) - the default value for LDFLAGS is wrong, "-z relro" is an option for "ld" but when you pass it through gcc you need "-Wl,-z,relro" - I saw you tried to hack up some code to setup the SONAME... it does set the SONAME on the library but the library is still installed under the wrong name (libregfi.so instead of the name set in the SONAME) - the SONAME must not encode the full version... it's only a simple counter of API/ABI compatibility. Please use "libregfi.so.0" as the first SONAME (and then bump to libregfi.so.1 when you break the ABI/API, etc.) (and 99.99.99.X looks really wrong as a version number :))
While lookinto in Scons support for versioned shared library I found this: http://stackoverflow.com/questions/2997001/how-to-get-shared-library-names-like-libhello-so-0-0-1-with-scons http://www.scons.org/doc/production/HTML/scons-user/apb.html#b-SharedLibrary So it looks like it's supported since version 2.3.0... I just tried this and got good results: --- a/SConstruct +++ b/SConstruct @@ -9,10 +9,9 @@ cflags = '-std=gnu99 -pedantic -Wall -D_ cflags += ' -DREGFI_VERSION=\'"%s"\' ' % REGFI_VERSION cflags += os.environ.get('CFLAGS','-fPIE -pie -fstack-protector -D_FORTIFY_SOURCE=2') -linkflags = "-shared -fPIC -Wl,-soname,libregfi.so.%s " % REGFI_VERSION +linkflags = "-shared -fPIC " linkflags += os.environ.get('LDFLAGS','-z relro -z now') lib_src = ['lib/regfi.c', @@ -31,7 +30,7 @@ env = Environment(ENV=os.environ, # Libraries libregfi_static = env.Library(lib_src) libregfi = env.SharedLibrary(lib_src, LIBS=['m','pthread', 'talloc'], - LINKFLAGS=linkflags) + SHLIBVERSION='0.0.0', LINKFLAGS=linkflags) # Executables @@ -64,7 +63,7 @@ install_bin = [destdir + bindir, destdir install_lib = [destdir + libdir, destdir + includedir + '/regfi'] env.Install(destdir+bindir, [reglookup, reglookup_recover, 'bin/reglookup-timeline']) -libinstall = env.Install(destdir+libdir, [libregfi, libregfi_static]) +libinstall = env.InstallVersionedLib(destdir+libdir, [libregfi, libregfi_static], SHLIBVERSION='0.0.0') env.Install(destdir+includedir+'/regfi', Glob('include/*.h')) env.Install(destdir+mandir+'/man1', [man_reglookup, man_reglookup_recover, man_reglookup_timeline]) but does not seem to make any difference between the version used in the filename (ideally libfoo.so.X.Y.Z) and the SONAME which is usually simpler (libfoo.so.X and which is the reason why the symlinks libfoo.so.X are needed when you install the library as libfoo.so.X.Y.Z). I would thus suggest to pass a single integer to SHLIBVERSION and not care about having a filename encoding the full version. full version filename and the SONAME Cheers, -- Raphaël Hertzog ◈ Debian Developer Support Debian LTS: http://www.freexian.com/services/debian-lts.html Learn to master Debian: http://debian-handbook.info/get/ -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
