Add support to IDA 7.0

[matrix1001]

Add support to IDA 7.0 and this tool will be much better.

[ALSchwalm]

Agreed, unfortunately, I no longer have access to IDA Pro, so this would have to be a community contribution.

[microtronics]

Any chance you can give info on how to build in windows? I'd like to try compiling against IDA 7 under Windows.

[ALSchwalm]

There is actually a windows branch that has a Makefile for windows. The setup is essentially to compile and statically link libdwarf under mingw, and then statically link that in when compiling dwarfexport.

@matrix1001 @matrix1001 I've ported it to 7.0 and created a pull request.

[mephi42]

In my case IDA 7 SDK did not contain MinGW-specific libraries (and linking with MSVC ones predictably led to crashes), so I had to take @nihilus's PR and add MSVC Makefiles on top. If you are interested, I can clean them up and send a PR.

[ALSchwalm]

@mephi42 I'd be ok with that. The previous PR just fell off my radar

Hi @ALSchwalm,

I just found out about the dwarfexport plugin today, and wow, I must say. It is really impressive what you've managed to implement, and definitely very useful!

I was wondering if the dwarfexport plugin may receive some well deserved love. I would indeed be a shame if a plugin this useful fell into the forgotten by not being synced with newer versions of IDA.

Wish you all the best and happy reversing!

Cheers, Robin

@mewmew, I'm currently using @nihilus's https://github.com/ALSchwalm/dwarfexport/pull/8 with IDA 7.0, and I can confirm that it's working great.

@ALSchwalm, what do you think needs to be done in order to integrate that pull request?

[mewmew]

@mewmew, I'm currently using @nihilus's #8 with IDA 7.0, and I can confirm that it's working great.

Hi @mephi42,

Thanks for the quick reply and feedback!

I tried #8 yesterday, but didn't get it working. I'm running on Linux and the latest version of both GCC and Clang was complaining about both error: a reinterpret_cast is not a constant expression, ‘struct idainfo’ has no member named ‘is_be’ and inf.is_64bit(). Perhaps there is something simple I've overlooked?
