There's no need to build the sleigh files to use r2ghidra, they are distributed in the release page as a zip (and compiled in the CI). but this shouldnt be failing, so i'll take a look. thanks for reporting!

For me, it is very important to be able to boostrap it from scratch :)

it builds fine for me, im unable to reproduce your problems, can you try again and confirm with a clean checkout? :?

Answer 4 · 2022-01-16T15:26:49.000Z

Sorry, I failed to mention I was compiling 5.5.2 and ghidra-native 0.1.3, I'll try again with 5.5.4 and 0.1.5 respectively.

Still failing with:

Build steps:

unpack r2ghidra
unpack ghidra-native
apply patches (make -C ghidra-native patch)
./configure && make

Unpack? Are you building from tarballs?

the ci (and me) always test this from git. Maybe is this the issue? Can u confirm?

Yes, I'm using the tarballs produced by github from the tags. That should not cause problems, nor the fact this is a musl-based system, but I mention it just in case.

Answer 8 · 2022-01-25T13:13:35.000Z

R2ghidra is known to not compile in ubuntu18 because the compiler shipped there have bugs. I never tried r2g on musl. But that could be affecting too. Which compiler are you using? Try with clang

Answer 9 · 2022-01-25T17:39:01.000Z

GCC 10.3.0, I can't upgrade to GCC 11 because it has a bug in libstdc++. I'll try with clang-13.

Answer 10 · 2022-01-26T14:27:05.000Z

I'm getting exactly the same error when compiling with clang 13.

Answer 11 · 2022-02-04T20:24:46.000Z

From where's the error exactly coming from? what does it mean?

Answer 12 · 2022-02-05T07:58:17.000Z

This error is generated by sleighc, you can grep the ghidra code for this string.

i can compile the sleigh files in my alpine machine which runs gcc++9 and musl. So not sure where your issue is coming from. Try running make in r2ghidra/ghidra or remove the executable there and run make again. I did a clean checkout right now and tested all your steps and it builds fine for me so i cant repro

Answer 13 · 2022-03-21T23:50:56.000Z

I'm still running into the same issue.

Answer 14 · 2022-03-22T13:24:35.000Z

Thats part of ghidra. Not r2ghidra.. and i assume there must be a problem with your memory or compiler. Can you please tell me whcich compiler and version and how much ram do u have so i can try to repro?

Answer 15 · 2022-03-22T13:26:08.000Z

Nvm u tried gcc and clang :? just read the backlog. When you say musl based distro do you mean alpine? I would like to be able to repro..

Yes, I tried with clang 13.0.1 now (got the same errors with llvm 12); gcc is 10.3.0. The machine has 16 GB of RAM, so that shouldn't be a problem. The distro is Source Mage. The musl-based build isn't official yet, but I could provide a rootfs tarball I guess. I'll try to make some time to test on Apline and work out the differences.
