Cannot run statically linked program? #205

Closed ghost closed 1 year ago

ptitSeb commented 3 years ago

Yes, I'm aware, that why I have put the comments there (you have made more clear it's "TODO:" comment)

ghost commented 3 years ago

I don't quite understand what you mean, what do I need to do?

ptitSeb commented 3 years ago

I'll fix it, wait a few minute. But I wonder why you seems so focus on execvp function???

ptitSeb commented 3 years ago

done

ghost commented 3 years ago

If there is a little error in the code, I will be very uncomfortable.

ghost commented 3 years ago

Although it will not affect the program...

ghost commented 3 years ago

i think you do not need handle execve,execvp... execute x86 elf. binfmt has done it.

ptitSeb commented 3 years ago

Yes, but I still want to handle it for plateform that don't use binfmt, or to be able to use another box86 copy than the one setup on binfmt.

run static linked, box86 will call a lot of nanosleep and then crash.

ghost commented 3 years ago

Why is this happening?

ptitSeb commented 3 years ago

How would I know?! I don't know what you are launching. Also, static linked program are still not supported with box86.

ghost commented 3 years ago

I am running printf HelloWorld. I thought you know why it crashed...

ptitSeb commented 3 years ago

well, static linked program is not a good idea with box86, as it defeat the "wrapped" concept at is at the heart of box86. I will not work on any workaround for static link program for now.

ghost commented 3 years ago

If box86 cannot run static linked programs, it doesn't matter.If box86 cannot use x86 printf, there may be a problem in box86.

ptitSeb commented 3 years ago

launch ctest in you box86 build folder. Does the tests runs ok?

If the x86 printf is from a statically linked program, than no, it's not a problem as staticaly linked program are not supported by box86 for now.

ghost commented 3 years ago

it is ok.

You mean printf of x86 libc can run on box86?

ptitSeb commented 3 years ago

What I mean is that I don't want to waste my time working on statically linked program, as it is not the main target of box86. printf is a complex function, while it may work, I'm unsure all the syscall needed are wired and correctly emulated. And again, this is out of scope for now.

ptitSeb commented 3 years ago

To be clear:

If you can debug and point me to some obvious mystake, I'll fix it. But I don't want to debug that myself.

ghost commented 3 years ago

OK.
