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.
