it worked !
( I had to removed references to the "dwarf" stuff however. )
Thanks alot. This helps greatly

Solaris compiles it's dmods with the following GCC invocation:
/usr/sfw/bin/gcc -fident -finline -fno-inline-functions -fno-builtin
-fno-asm \
-nodefaultlibs -D__sun -fno-strict-aliasing -fno-unit-at-a-time
-fno-optimize-sibling-calls -O2 -m64 -mtune=opteron -Ui386 -U__i386
-Wall -Wno-unknown-pragmas -Wno-missing-braces -Wno-sign-compare
-Wno-parentheses -Wno-uninitialized
-Wno-implicit-function-declaration
-Wno-unused -Wno-trigraphs -Wno-char-subscripts -Wno-switch -Werror
-std=gnu89 -gdwarf-2 -std=gnu89 -fno-dwarf2-indirect-strings -fPIC
-DTEXT_DOMAIN="SUNW_OST_OSCMD" -D_TS_ERRNO -D_ELF64 -D_KERNEL
-ffreestanding -c -o test.o test.c
(I'm sure that many of these options aren't needed)
And then links it with:
/usr/sfw/bin/gcc -fident -finline -fno-inline-functions -fno-builtin
-fno-asm
-nodefaultlibs -D__sun -fno-strict-aliasing -fno-unit-at-a-time
-fno-optimize-sibling-calls -O2 -m64 -mtune=opteron -Ui386 -U__i386
-Wall
-Wno-unknown-pragmas -Wno-missing-braces -Wno-sign-compare
-Wno-parentheses
-Wno-uninitialized -Wno-implicit-function-declaration -Wno-unused
-Wno-trigraphs
-Wno-char-subscripts -Wno-switch -Werror -std=gnu89 -gdwarf-2
-std=gnu89
-fno-dwarf2-indirect-strings -DTEXT_DOMAIN="SUNW_OST_OSCMD"
-D_TS_ERRNO
-D_ELF64 -D_KERNEL -ffreestanding -Wl,-Bdirect -shared test.o -o
test.so
Do these work for you?
Cheers,
