Support for exporting multiple databases to 1 .BinExport (or for merging .BinExport files)

That is not currently supported by any of the tools. A .BinExport files is supposed to represent a full binary. That said, if you have multiple disassembly databases that share the same address space (like in your case with a bunch of separate object files), this is a reasonable thing to want.

As a workaround, you could simply link the .o files together and use the resulting executable as some kind of container. Then you can create a single .idb and export that one.

IIRC, IDA also supports loading additional binary files into an IDB. So if you have a database open, File|Load input file (or similar, not near my IDA installation right now) should allow you to load another object file.

Failing that, it's is relatively straighforward to write a small tool that takes a set of .BinExport files and produces a "merged" one by iterating over all instructions/basic blocks/functions and adding them.

As for the batch diff/export case, take a look at issue 150583990 in the BinDiff bug tracker. That bug also has updated binaries that should allow you to export successfully.

Thank you @cblichmann! Good ideas.

I'm currently trying rizzo with Ghidra.
If i can't make that work I'll try the methods you suggested.

@cblichmann thanks so much for the referenced issue issue 150583990. However, I have encountered an issue in that was supposedly addressed in that issue. I added a follow-up comment on the issue. Hoping you can get around to checking it out! Let me know if I need to open a new issue here, on there
