| 6 | # The 'cc-shared' module provides support for shared libraries and shared objects. |
|---|
| 7 | # It defines the following variables: |
|---|
| 8 | # |
|---|
| 9 | ## SH_CFLAGS Flags to use compiling sources destined for a shared library |
|---|
| 10 | ## SH_LDFLAGS Flags to use linking (creating) a shared library |
|---|
| 11 | ## SH_SOPREFIX Prefix to use to set the soname when creating a shared library |
|---|
| 12 | ## SH_SOFULLPATH Set to 1 if the shared library soname should include the full install path |
|---|
| 13 | ## SH_SOEXT Extension for shared libs |
|---|
| 14 | ## SH_SOEXTVER Format for versioned shared libs - %s = version |
|---|
| 15 | ## SHOBJ_CFLAGS Flags to use compiling sources destined for a shared object |
|---|
| 16 | ## SHOBJ_LDFLAGS Flags to use linking a shared object, undefined symbols allowed |
|---|
| 17 | ## SHOBJ_LDFLAGS_R - as above, but all symbols must be resolved |
|---|
| 18 | ## SH_LINKRPATH Format for setting the rpath when linking an executable, %s = path |
|---|
| 19 | ## SH_LINKFLAGS Flags to use linking an executable which will load shared objects |
|---|
| 20 | ## LD_LIBRARY_PATH Environment variable which specifies path to shared libraries |
|---|
| 21 | ## STRIPLIBFLAGS Arguments to strip a dynamic library |
