Sorry for the long wait, I was on a prolonged leave.

Can you share what command / configuration you used to build these? I think I'll need to repro that myself; I cannot accept arbitrary binaries into the project that I didn't build, for security reasons (I hope you can understand that).

@mprobst Sorry, I was busy working on my other PRs, so I couldn't really get back to you. I noticed that the way I built the binary earlier was not the right way as it was 94 MB! So, I have rebuilt it using the info given in the readme with some slight modifications as the default script did not work. I have updated the PR info with the script I used. I'll shoot a PR to update the same in the readme.

PR to fix the build script: #71

@mprobst gentle reminder, in case you forgot about reviewing this PR and the one I linked to above :)

@mprobst bump

[mprobst]

Sorry, the bottleneck is that I do now know how to produce an i386 binary on an x64 machine (i.e. cross compile in llvm), and as I said above, I cannot just accept a compiled binary from a third party, for security reasons (not that I have reasons not to trust you, but general policy is to only accept changes that can be reviewed, and the binary dump here cannot be reviewed).

Do you have a suggestion for a cross compilation setup here?

[RaisinTen]

@mprobst I have updated the script in the PR description to build a 32-bit binary by adding the -DCMAKE_GENERATOR_PLATFORM=x86 option to cmake. You could try this locally and then compare the file hashes. I can't test this myself because I don't use a 32-bit Linux anymore.

[mprobst]

If you don't use 32bit linux, nor do I - do we believe this really helps anyone at this point?

[RaisinTen]

Eh, probably not. I'm okay with closing this at this point in time! :)
