| 2 | * HPUX 10.x stubs to implement dl* in terms of shl*
|
|---|
| 3 | *
|
|---|
| 4 | * Not needed for later versions; HPUX 11.x has dlopen() and friends.
|
|---|
| 5 | *
|
|---|
| 6 | * configure also needs to be faked out. You can create a dummy libdl.a
|
|---|
| 7 | * with stub entries for dlopen, dlclose, dlsym, and dlerror:
|
|---|
| 8 | *
|
|---|
| 9 | * int dlopen() { return(0);}
|
|---|
| 10 | * int dlclose() { return(0);}
|
|---|
| 11 | * int dlsym() { return(0);}
|
|---|
| 12 | * int dlerror() { return(0);}
|
|---|
| 13 | *
|
|---|
| 14 | * This has not been tested; I just read the manual page and coded this up.
|
|---|
| 15 | *
|
|---|
| 16 | * According to the ld manual page, you need to link bash with -dld and add
|
|---|
| 17 | * the -E flag to LOCAL_LDFLAGS.
