Support for 64-bit broken somewhere after tag 0.2d19 #39

Closed marcomaggi closed 11 years ago

marcomaggi commented 11 years ago

The code generates invalid boot images for 64-bit platforms.

Have you tried "git bisect" to find the commit that broke it?

marcomaggi commented 11 years ago

Who is your "you"? :-) The only way to identify the commit that broke it is: use a 64-bit computer, checkout a commit, build a new boot image, try to run it. "git bisect" helps with the 3 latter steps, but I do not own a 64-bit computer. If someone wants to contribute time to do this search, he is welcome.

@ChaoeEternal: have you verified that the boot image in the latest release is still broken?

ChaosEternal commented 11 years ago

Yes, 0.2d21 is still broken On Feb 13, 2013 3:11 AM, "Marco Maggi" notifications@github.com wrote:

marcomaggi commented 11 years ago

Thanks!!! I will upload soon a test release with a fix.

marcomaggi commented 11 years ago

It should be fixed now in the devel branch, commit e0107d37acc6f8cbe6fd4a9b542883e01ddc7481.

marcomaggi commented 11 years ago

It is not fixed. Many bugs shown by the test suite. Development of 64-bit support goes on on the branch "support-for-64-bit".

marcomaggi commented 11 years ago

Should be fixed in the head of the devel branch.

ChaosEternal commented 11 years ago

Great job!!!
