building capstone inside radare2 on cygwin - error

[XVilka]

building capstone (next) on cygwin from radare2 gives me this error:

This is also without IS_CYGWIN=1.
But if you change to IS_CYGWIN=0 it builds ok, but bitching about -fPIC (you already handling this in your code for cygwin, so your makefile just can't determine my cygwin properly:

if [ ! -d capstone ]; then \
    git clone https://github.com/aquynh/capstone.git ; \

    git checkout next ; \

The first issue is because when compiling for cygwin the library name is capstone.lib instead of libcapstone.a. that’s why forcing IS_CYGWIN=1 is necessary for us.

The fPIC thing can be fixed by overriding the CFLAGS after make.

yes, on Windows i have renamed libcapstone.* to capstone.* because those are more like conventional names for Windows.

thanks.
