XCompiler

[brodeur235]

All I need is binutils to run on my mac 10.6 snow leopard to complete builds of my OS. (the only tools I used on a linux machine were nasm and ld). I have nasm working, but binutils will not install. YES! I've read the cross compiler wiki article and following it's instructions or not, I get an error. Here's what I get:

No, you did not follow the instructions. Read the tutorial again and follow it to the letter.

I think this might be a tip to help you:

Code: Select all

i386-pc-none

[brodeur235]

I've now set up the dir tree exactly how the tutorial specifies and with the same environment vars. Configuration ends with this error:

Code: Select all

configure: error: installation or configuration problem: C compiler cannot create executables.
Configure in /usr/src/build-binutils/bfd failed, exiting.

I used i586-elf and installed to the correct dir /usr/cross. Help appreciated,

binutils-2.10.1

Did you fix that yet?

[Brynet-Inc]

Yet another person fails to read dates, here's a hint.. 2.10.1 was released in what year?

[brodeur235]

Thank you both. I got it installed. Also, a note for anyone else trying to install binutils on mac 10.6 Snow Leopard, when you configure binutils you have to add the -disable-werror option in addition to the others. Otherwise, 5 warnings result as errors stopping the make.

I do have another problem however, that has been asked about a hundred times, yet I can't understand the problem still. Sorry for being so difficult; I'm probably really frustrating and for that I apologize. Anyways, I've got my OS that I coded over the summer on ubuntu and it compiled, linked, and ran fine then. Now, there is a problem I've never seen before. There are about 30 modules to the OS so I'll only include the ones that pertain...

Most people who had this same error were switching in and out of protected and real mode. All I do is switch to protected once and jump to my kernel. I don't understand why this doesn't work all of a sudden because it did in Ubuntu...

[Combuster]

At least your building pipeline is broken - you are assuming that your linker puts everything starting from address 0, which is not the case. I would expect it to break in ubuntu too.

Also, a bug (not a feature IMNSHO) in ld makes that the relocation truncations become warnings, not errors like they should be. Your binary is corrupt, end of story.
