XL Fortran Enterprise Edition for AIX : User's Guide - IBM

-bdynamic, -bshared, and -bstatic Options
Syntax
-bdynamic | -bshared | -bstatic
These options are toggles that are used to control the processing of -l options and
the way that shared objects are processed.
The options -bdynamic and -bshared are synonymous.
When -bstatic is in effect, shared objects are statically linked into the output file.
When -bdynamic is in effect, shared objects are linked dynamically.
When -brtl is used in conjunction with either -bdynamic or -bshared, the search
for libraries specified with the -l option is satisfied by the suffix .so or .a. For each
directory searched, a file with the suffix .so is looked for. If it is not found, a file
with the suffix .a is looked for. If neither file is found, the search continues with
the next directory.
Rules
These options are passed directly to the ld command and are not processed by XL
Fortran at all.
These options are position-significant. They affect all files that are specified after
the option on the command-line.
Table 13 summarizes how these options interact with -brtl and -bnortl to affect the
file suffix that is being searched.
