I'm make the shared library with asm-object files and get the warning:

gcc -shared -fPIC -o libgost.so gostcrypt.o gamma.o gammale.o gost.o imito.o mktbl.o
/usr/lib/gcc/i686-pc-linux-gnu/3.4.4/../../../../i686-pc-linux-gnu/bin/ld: warning: creating a DT_TEXTREL in object.



With greating static library all ok. Where problem?

This is a stab in the dark but do you assemble to an ELF and link (ld) with '-shared' switch ?

btw - do you have an example of a simple module that compiles to an SO ?
Im wondering is the module has an entry point like "start:"

format ELF
public gost
public gost32

section '.text' executable

gost:
_gost:
iloop: mov ebp,eax

add eax,[esi]
add esi,4

repeat 3
xlatb
ror eax,8
add ebx,100h
end repeat

xlatb
sub ebx,300h

rol eax,3

xor eax,edx
mov edx,ebp

loop iloop
ret



gost32:
_gost32:
push esi
push ebx
push ebp

mov ebx,[esp+16]
push ebx
mov eax,[ebx]
mov edx,[ebx+4]
mov esi,[esp+24]
mov ebx,[esp+28]
mov ecx,[esp+32]
push ecx

call gost

pop ecx
cmp ecx,32
je .exit
xchg eax,edx

.exit:
pop ebx
mov [ebx],edx
mov [ebx+4],eax

pop ebp
pop ebx
pop esi
ret

I heard that gcc could compile assembler code, can somone say if a gcc command could compile the fasm code above???

gcc ???-ASM??? myprog.asm

for sure gcc cannot compile FASM code. maybe it can compile some ugly AT&T-syntax code, but i doubt it, there is gas for that.

Yes the intel syntax is not exactly like the At&T syntax.

You'd have to invert all operands since AT&T uses:
mnemonic source, dest
and FASM uses:
mnemonic dest, source

You'd have to prefix all register names with a %
For example eax would become %eax

Same for constant/immadiate values: prefixed with $

etc...

Did you try without -fPIC

the nasm documention has something about getgot
and the need for the shared objects to get the address of where thay are loaded
and this has to be set I think into the local discrpter table so the addresses in the code can be found

Yes... Same result
