Building on Mingw64

Building on Mingw64

[Daniel Holden]

Hi all,

I'm having a little trouble building libffi on Windows 7 64 bit using 
Mingw64 (http://mingw-w64.sourceforge.net/).

Here is the error message on compile:

libtool: compile:  gcc -DHAVE_CONFIG_H -I. -I.. -I. -I../include

I know very little about assembly but this looks like a 32/64 bit issue. 
Is MinGW64 supported as a compiler?

The reason I ask is that I was getting some issues when I was using 
Pyton ctypes and trying to call particular functions in a C library 
compiled using MinGW64. The details I outlined in this stack overflow 
question:

http://stackoverflow.com/questions/13275211/python-ctypes-stack-corruption

I was going to test to see if just using libffi also gives any issues.

Thanks,

Dan

Did you use the configure script and provided the host?

configure --host=x86_64-w64-mingw32?

Because that is required to enable the 64bits mode on my end.

I've compiled libffi in 64bits mode without troubles with mingw-w64
compiler, see binary packages mentioned here:

https://groups.google.com/forum/?fromgroups=#!topic/rubyinstaller/Lp-OukkdGQE

The 64bits version was obtained using tdm64 variant of mingw-w64, but
is mingw-w64 at the end. The trick is always configure with the right
host flag.

Let us know if that helps.

Hi,

Many Thanks - that managed to get it to compile.

I set up a small test program again and now I believe I have encountered 
the same issue I was getting when using Python ctypes. I will have to 
investigate a bit more before I have an idea of what exactly is going on 
but there is some very odd stuff and I may have found a bug.

For example upon calling the troublesome function using the ffi my 
program crashes and in the stack-trace is a call to a completely 
unrelated function in my library. I will try to get my head around what 
is happening and post a more detailed breakdown soon.
