You can use the #dump -Tv command to see the symbols of the object. Also u can use the "nm" command. See the manual for details. In the first place take out the libfl.a from Makefile, it doesnt exist anyway. Find unresolved symbols (either with a map file or via nm) and see if u can find these functions in your Solaris. This must not be standard, since it doesnt exist either in AIX. I suppose then it is a difficult job to do, since you may have to rewrite these functions...

DEPMOD(8)							      depmod								 DEPMOD(8)

depmod - Generate modules.dep and map files. SYNOPSIS
depmod [-b basedir] [-e] [-E Module.symvers] [-F] [-n] [-v] [-A] [-P prefix] [-w] [version] depmod [-e] [-E Module.symvers] [-F] [-m] [-n] [-v] [-P prefix] [-w] [version] [filename...] DESCRIPTION
Linux kernel modules can provide services (called "symbols") for other modules to use (using one of the EXPORT_SYMBOL variants in the code). If a second module uses this symbol, that second module clearly depends on the first module. These dependencies can get quite complex. depmod creates a list of module dependencies by reading each module under /lib/modules/version and determining what symbols it exports and what symbols it needs. By default, this list is written to modules.dep, and a binary hashed version named modules.dep.bin, in the same directory. If filenames are given on the command line, only those modules are examined (which is rarely useful unless all modules are listed). depmod also creates a list of symbols provided by modules in the file named modules.symbols and its binary hashed version, modules.symbols.bin. Finally, depmod will output a file named modules.devname if modules supply special device names (devname) that should be populated in /dev on boot (by a utility such as udev). If a version is provided, then that kernel version's module directory is used rather than the current kernel version (as returned by uname -r). OPTIONS
-a --all Probe all modules. This option is enabled by default if no file names are given in the command-line. -A --quick This option scans to see if any modules are newer than the modules.dep file before any work is done: if not, it silently exits rather than regenerating the files. -b basedir --basedir basedir If your modules are not currently in the (normal) directory /lib/modules/version, but in a staging area, you can specify a basedir which is prepended to the directory name. This basedir is stripped from the resulting modules.dep file, so it is ready to be moved into the normal location. Use this option if you are a distribution vendor who needs to pre-generate the meta-data files rather than running depmod again later. -C --config file or directory This option overrides the default configuration directory at /etc/depmod.d/. -e --errsyms When combined with the -F option, this reports any symbols which a module needs which are not supplied by other modules or the kernel. Normally, any symbols not provided by modules are assumed to be provided by the kernel (which should be true in a perfect world), but this assumption can break especially when additionally updated third party drivers are not correctly installed or were built incorrectly. -E --symvers When combined with the -e option, this reports any symbol versions supplied by modules that do not match with the symbol versions provided by the kernel in its Module.symvers. This option is mutually incompatible with -F. -F --filesyms Supplied with the produced when the kernel was built, this allows the -e option to report unresolved symbols. This option is mutually incompatible with -E. -h --help Print the help message and exit. -n --dry-run This sends the resulting modules.dep and the various map files to standard output rather than writing them into the module directory. -P Some architectures prefix symbols with an extraneous character. This specifies a prefix character (for example '_') to ignore. -v --verbose In verbose mode, depmod will print (to stdout) all the symbols each module depends on and the module's file name which provides that symbol. -V --version Show version of program and exit. See below for caveats when run on older kernels. -w Warn on duplicate dependencies, aliases, symbol versions, etc. COPYRIGHT
