编译ffmpeg的so库，不带版本号后缀

asking questions leads always to finding answers. that's why i was successful, digging into the make files helped. do the following:

• run your configuration
• find "config.mak"

• change

  SLIBNAME_WITH_VERSION=$(SLIBNAME).$(LIBVERSION) SLIBNAME_WITH_MAJOR=$(SLIBNAME).$(LIBMAJOR)

  to:

  SLIBNAME_WITH_VERSION=$(SLIBNAME)
  SLIBNAME_WITH_MAJOR=$(SLIBNAME)

• change

  SLIB_INSTALL_NAME=$(SLIBNAME_WITH_VERSION) SLIB_INSTALL_LINKS=$(SLIBNAME_WITH_MAJOR) $(SLIBNAME)

  to:

  SLIB_INSTALL_NAME=$(SLIBNAME)
  SLIB_INSTALL_LINKS=

• run "make" or "make -j$(nproc)"

• "make install"

now you will have shared libraries without suffixes.
you can check their dependencies by "readelf -d somefile.so"
