Re: [Linux-abi-users] Problem with COFF binary on 2.6.x

[Anibal A. <deb...@gm...>]

Hi Alex.

> You seem to be running the old "REGPARMS patch" for 2.6.16 - it was super=
seded by iBCS-3.x.

Yes, I used the old patch.

But, I found the problem finally.

Based in other comment from other linux-abi user.
He asked to me =BFWhy did you compile static under 2.6.x if you had the
patch working fine under 2.4.20? it was for other reasons, but yes, it
was the answer.

I don't know why, but I compiled the kernel 2.6.x (I proved with
2.6.16 and 2.6.18 in both working fine) with the Linux-Abi patch as
modules (likes 2.4.20) and working my app works fine (finally):

I had (in whatever 2.6.x):

CONFIG_BINFMT_MISC=3Dy
CONFIG_ABI=3Dy

# CONFIG_ABI_XTI_OPTMGMT is not set
CONFIG_ABI_SYSCALL_STATICS=3Dy

But I modified, then:

CONFIG_BINFMT_MISC=3Dy
CONFIG_ABI=3Dy
CONFIG_ABI_SVR4=3Dm

#

# CONFIG_ABI_XTI_OPTMGMT is not set
# CONFIG_ABI_SYSCALL_STATICS is not set
CONFIG_ABI_SYSCALL_MODULES=3Dy
CONFIG_ABI_LCALL7=3Dm

And my app is working now.  Why? is as module better for this patch?
For my app thus it was.


For last, Alex, I had problems with you IBCS 3.3 app, not for "many".
Just were 3 or 4 apps, but I know the future for the linux-abi is your
IBCS3. If you want, I can send you the output from these apps (the
The 2.6.18 is the last kernel where the original patch works, then for
future update, the IBCS3 must work :P

Regards

I hope this project follows with live. Many users (like me and my
company) depends on this support.
