Nope, just need a FPC crosscompiler, it has windows linker and assembler (16*,32,64-bit) built in.

* 16-bit only in development versions afaik.

Ok thank you, i have just installed the fpc cross compiler package in arch linux, but i dont know how to configure the fpc for all targets i need, with this i mean in my /usr/lib/fpc/3.3.1/ directory i only have ppcx64 file, nothing for win64 or other platforms as needed so my Lazarus when i change the target in the project options, it complains that fpc is not correctly configured for win64 platform and x86_64 cpu which is what i have choosen as target, hope you can help me with this not much information arround even at Arch Linux forums, thank you in advance.

FPC compilers are generally per architecture, not per target, so the x86_64 linux compiler (ppcx64) can also compile for win64.

But you need to build the libraries.

Copy relevant units/ tree from a Windows install and putting it in /usr/lib/fpc/3.3.1/units/x86_64-win64 might be the easiest way to get started.

It should be the same 3.3.1 though, since 3.3.1 is a rolling development version

In, for example, c:\lazarus\fpc\3.3.1\units\x86_64-win64\ or thereabout for a standard Lazarus-Win64 installation.
