Depends on # the variable LIB_INSTALL_DIR in the Makefile. # MAKE_LIB - Command to execute to build the Tcl library; # differs depending on whether or not Tcl is being # compiled as a shared library. # SHLIB_CFLAGS - Flags to pass to cc when compiling the components # of a shared library (may request position-independent # code, among other things). # SHLIB_LD - Base command to use for combining object files # into a shared library. # SHLIB_LD_LIBS - Dependent libraries for the linker to scan when # creating shared libraries. This symbol typically # goes at the end of the "ld" commands that build # shared libraries. The value of the symbol is # "${LIBS}" if all of the dependent libraries should # be specified when creating a shared library.
