| 35 | .TP | |
| 36 | .B \-r\ \-\-function\-relocs | |

| 41 | Usage information. | |
| 42 | .SH NOTES | |
| 43 | The standard version of | |
| 44 | .B ldd | |
| 677f4766 MK |
45 | comes with glibc2. |
| 46 | Libc5 came with an older version, still present | |
| ca7b3c18 MK |
47 | on some systems. |
| 48 | The long options are not supported by the libc5 version. | |
| fea681da MK |
49 | On the other hand, the glibc2 version does not support |
| 50 | .B \-V | |
| 51 | and only has the equivalent | |
| 52 | .BR \-\-version . | |
| 53 | .LP | |
| 54 | The libc5 version of this program will use the name of a library given | |
| f81fb444 | 55 | on the command line as-is when it contains a \(aq/\(aq; otherwise it |
| ca7b3c18 MK |
56 | searches for the library in the standard locations. |
| 57 | To run it | |
| fea681da MK |
58 | on a shared library in the current directory, prefix the name with "./". |
| 59 | .SH BUGS | |
| 60 | .B ldd | |
| 61 | does not work on a.out shared libraries. | |
| 62 | .PP | |
| 63 | .B ldd | |
| 64 | does not work with some extremely old a.out programs which were | |
| 65 | built before | |
| 66 | .B ldd | |
| 67 | support was added to the compiler releases. | |
| 68 | If you use | |
| 69 | .B ldd | |
| 70 | on one of these programs, the program will attempt to run with | |
| 71 | \fIargc\fP = 0 and the results will be unpredictable. | |
