Solaris 1.x to 2.x Transition Guide

Link Editor Option Differences

Some options have been renamed in the new linker, some have remained the same, and others are no longer needed. Table 15-3 compares the SunOS release 4.x ld command to the Solaris 2.6 ld command.

The sections following Table 15-3 explain how certain linking tasks are affected by the option differences.

Table 15-3 Comparison of ld Options


SunOS release 4.x Option	Solaris 2.6 Replacement	Notes
`-align` `datum`	`-M` `mapfile`	Uses `mapfile` and distinct sections
`-assert definitions`	Default
`-assert nodefinitions`	`-znodefs`	Issues a fatal error instead of a warning
`-assert nosymbolic`	`-zdefs`	Issues a fatal error instead of a warning
`-assert pure-text`	`-ztext`	Issues a fatal error instead of a warning
`-A` name	No replacement	`dlopen`(3X) and `dlclose`(3X) can approximate this behavior
`-Bdynamic`	`-Bdynamic`	Applies only to the inclusion of shared libraries; use `-dy` (the default) to build dynamically linked executables. See "Building Executables".
`-Bnosymbolic`	`-zdefs`
`-Bstatic`	`-dn` & `-Bstatic`	The `-dn` option must be specified to completely eliminate the dynamic linker. Use `-Bstatic` in dynamic mode to include archive libraries. (Used as a toggle. See "Building Executables".)
`-Bsymbolic`	`-Bsymbolic`	Also gets `-assert nosymbolic` with this option
`-d` `-dc` `-dp`	Default	Use `-b` option in SVR4 to turn off
`-D hex`	`-M` `mapfile`	`mapfile` contains different mechanisms to accomplish desired effect
`-e` `entry`	`-e` `entry`
no `-e`	`-G`	Creates a shared object
`-lx[.v]`	`-lx`	Only major number versioning of shared libraries is currently supported
`-Ldir`	`-Ldir`	`dir` not recorded in executable; use `-R` option instead.
`-M`	`-m`
`-n`	Default	SVR4 executable format compresses disk image as `-n`
`-N`	No replacement
`-o` `name`	`-o` `name`
`-p`	Default	Can override with `-M` `mapfile`
`-r`	`-r`
`-S`	No replacement
`-s`	`-s`
`-t`	No replacement
`-T` `hex`	`-M` `mapfile`	`mapfile` contains different mechanisms to accomplish desired effect
`-Tdata` `hex`	`-M` `mapfile`	`mapfile` contains different mechanisms to accomplish desired effect
`-u` `name`	`-u` `name`
`-x`	No replacement
`-X`	No replacement
`-y` `sym`	No replacement
`-z`	Default	SVR4 executable format demands pages as `-z`
