Thank you for this long explaination. I just think there is a typo: [...] > How would we do that ? We need to tell the linker how to create the > library file: > > compilation flags to build your libkleeRuntest shared object lib: > > -shared -fPIC -Wl,-soname,libkleeRuntest.so.1.1 -o libkleeRuntest.so.1.1 The argument of the linker option -soname should be the soname and not the real name: -shared -fPIC -Wl,-soname,libkleeRuntest.so.1 -o libkleeRuntest.so.1.1 as this is reflected by your output: [...] > readelf -d libkleeRuntest.so.1.1 [...] > 0x000000000000000e (SONAME) Library soname: > [libkleeRuntest.so.1] ^^^^ no libkleeRuntest.so.1.1 but the correct libkleeRuntest.so.1 soname > 0x000000000000000c (INIT) 0x4e68 And a few remarks: * if the upstream build system want to *link* with this library (after creating it), it will need to either use the real name or (better) to create the required link (the libNAME.so link) * if the upstream build system want to *run* this library (for example as part of a test suite), it will need to create the other link (the libNAME.so.SOVERSION link) and to play with LD_LIBRARY_PATH (or use LD_PRELOAD) It is were build frameworks such as autotools/libtools helps the developer...
