/*
|
||||||
|
* Program to generate the auto_solib_add_threshhold testcase,
|
||||||
|
* including associated linked-against shared libraries.
|
||||||
|
* Build as:
|
||||||
|
*
|
||||||
|
* cc -g -o gen_auto_solib_add_threshhold gen_auto_solib_add_threshhold.c
|
||||||
|
*
|
||||||
|
* Invoke as:
|
||||||
|
*
|
||||||
|
* gen_auto_solib_add_threshhold
|
||||||
|
*
|
||||||
|
* It will put all the code in the current directory (".").
|
||||||
|
*
|
||||||
|
* A makefile can also be generated if the -makemake option is used.
|
||||||
|
* To use the makefile:
|
||||||
|
*
|
||||||
|
* make -f auto_solib_add_threshhold.mk all
|
||||||
|
*
|
||||||
|
* The name of the application is
|
||||||
|
*
|
||||||
|
* auto_solib_add_threshhold
|
||||||
|
*
|
||||||
|
* (Revised from a program by John Bishop. --rehrauer)
