Example One

The following command input creates the DLL:

run $data01.toolsy02.eld mystro -o mystrdll -shared -export_all

eld - TNS/E Native Mode Linker - T0608H01 - 26OCT04

eld command line:

\speedy.$data01.toolsy02.eld mystro -o mystrdll -shared -export_all

**** INFORMATIONAL MESSAGE **** [1530]:

Using 'ImpImp' file: \speedy.$data01.toolsy02.zimpimp.

Output file: mystrdll (dll)

Output file timestamp: Nov 8 13:59:43 2004

Now Build the Program

The next step is to create the loadfile (the whole program) by use of the linker.

ccplmain contains initialization code for the C and C++ run-time libraries. Your

version of that file will probably be located in $system.system.

ccplmain contains external references to errno and environ (which are defined in

ZCREDLL) and C_INT_INIT_COMPLETE_ , C_INT_INIT_START_ , and exit (which

are defined in ZCRTLDLL).

Note that each DLL must use an individual -lib option to be linked with eld. The

command syntax does not allow for a single -lib option followed by a list of DLLs, for

example: -lib zcredll, zcrtdll, mystrdll is not valid syntax.
