| 5 | # This shell script provides a wrapper for ld under AIX in order to | |
| 6 | # create the .exp file required for linking. Its arguments consist | |
| 7 | # of the name and arguments that would normally be provided to the | |
| 8 | # ld command. This script extracts the names of the object files | |
| 9 | # from the argument list, creates a .exp file describing all of the | |
| 10 | # symbols exported by those files, and then invokes "ldCmd" to | |
| 11 | # perform the real link. | |

| 29 | # Create the export file from all of the object files, using nm followed | |
| 30 | # by sed editing. Here are some tricky aspects of this: | |
| 31 | # | |
| 32 | # 1. Nm produces different output under AIX 4.1 than under AIX 3.2.5; | |
| 33 | # the following statements handle both versions. | |
| 34 | # 2. Use the -g switch to nm instead of -e under 4.1 (this shows just | |
| 35 | # externals, not statics; -g isn't available under 3.2.5, though). | |
| 36 | # 3. Use the -X32_64 switch to nm on AIX-4+ to handle 32 or 64bit compiles. | |
| 37 | # 4. Eliminate lines that end in ":": these are the names of object | |
| 38 | # files (relevant in 4.1 only). | |
| 39 | # 5. Eliminate entries with the "U" key letter; these are undefined | |
| 40 | # symbols (relevant in 4.1 only). | |
| 41 | # 6. Eliminate lines that contain the string "0|extern" preceded by space; | |
| 42 | # in 3.2.5, these are undefined symbols (address 0). | |
| 43 | # 7. Eliminate lines containing the "unamex" symbol. In 3.2.5, these | |
| 44 | # are also undefined symbols. | |
| 45 | # 8. If a line starts with ".", delete the leading ".", since this will | |
| 46 | # just cause confusion later. | |
| 47 | # 9. Eliminate everything after the first field in a line, so that we're | |
| 48 | # left with just the symbol name. | |
