Build issues in Mac OS X

[deevashwer]

I ran the cmake .. command successfully.
On running the make command, I saw the following error messages:

Can someone suggest any changes to Makefile that will resolve this issue?

[lenerd]

Hi,
I think, there might be an #include <array> missing in rcvthread.h of ENCRYPTO_utils. Can you try to add this and tell me if it is sufficient?

[deevashwer]

I added the include statement, and it solved the particular issue, but some new errors popped up later.

I have no idea about MacOS, but it seems that it somehow does not define SOL_TCP.

What I found through a quick Google search was this workaround:
unbit/uwsgi@b608eb1
Maybe you can try that.

Unfortunately we have no possibility to test ABY on MacOS, so this is rather hard to debug from our side.

[deevashwer]

The major problem I'm facing is that OS X doesn't yet support "filesystem".
Is there a version of ABY that doesn't use "filesystem" or "experimental/filesystem"?

[lenerd]

You could just use ABY before commit dafae66.

[dd23]

Or alternatively, you could install gcc8, which comes with support for the filesystem library.
The older version, gcc7 should support experimental/filesystem.
There are already modifications that introduce experimental/filesystem as alternative in 11c4986 from #87

[deevashwer]

I tried doing that. The problem is that I had some linking issues since the GMP that I have installed was compiled with clang.
I would try installing GMP again with gcc8, if some older version of the repository is not compatible.

[deevashwer]

Having tried both the alternatives, I am stuck at this error:

[lenerd]

Is C++ support enabled in your GMP library?

[deevashwer]

Yes. It is enabled. cmake was able to locate the gmpyxx.dylib as well.

[deevashwer]

I managed to install a previous version of the library.
I started testing the executables in the bin directory.
Some of them are producing the wrong output, for example, abyfloat_test with the following error:

Error: Unable to open circuit file circ/fp_nostatus_add_64.aby

and bench_operations with the following error:

For the missing circuit files see #83 .
