I quess I didn't load it.

At the moment I try to modify dl01 example to load dl-o1.o from filesystem.

My Makefile:
all:
    i386-rtems4.11-gcc -B$(RTEMS_MAKEFILE_PATH)lib/ -specs bsp_specs

    mv dl01.pre.exe dl01.pre
    rtems-syms -e -c "-mtune=i486 -O2 -g -Wall -Wmissing-prototypes
-Wimplicit-function-declaration -Wstrict-prototypes -Wnested-externs" *-o

    i386-rtems4.11-gcc -B../../../../../pc486/lib/ -specs bsp_specs -qrtems
-mtune=i486 -O2 -g -Wall -Wmissing-prototypes

-Wl,-Ttext,0x00100000  -mtune=i486 *-o dl01.exe init.o dl-load.o dl-o1.o
dl-sym.o filesystem.o*

filesystem.c contains functions to mount dos partition.

The output is:
dlopen failed: duplicate global symbol: rtems_main
