Bochs-2.4.5 configure fails - needs Linux kernel 2.4 or 2.6

[thegamerdude23]

Hey guys,
I can't get bochs to compile. I must be doing something wrong lol. I tried searching for an easy fix for this, there has to be one. I never found anything. Will I have to write my own ebuild and patch? I can't even find anyone with the same problem. here is exactly what is says at the end of the configure...

Code: Select all

configure: Linux detected as host for PCI host device mapping
configure: error: Linux kernel 2.4 or 2.6 is required

Here are the use flags in case it will help.

Code: Select all

Bochs USE FLAGS: X acpi debugger ncurses readline usb -sdl (-svga) -vnc -wxwidgets

Thanks.

What does

Code: Select all

uname -a

in a terminal return?
Which kernel do you have installed? Looking at gentoo-sources, the current highest stable kernel is 3.1.6, so if you have that installed, maybe that's why the configure stage is failing.

I know that I'm on kernel 3.2.0. I'm wondering if there is anything that I can do about that error. I want to install bochs.

Build by hand, there is a much never version available. Filing a bug with ebuild upgrade request will help, too.

[paulj]

In these circumstances, I normally try the following:

• Is there an overlay with a later version available (google is your friend)
• If not, make your own ebuild, and use that to install it. I have a local tree at /usr/local/portage, and have added

  Code: Select all

  PORTDIR_OVERLAY=/usr/local/portage

  in /etc/make.conf. Use the existing ebuild from the tree as a basis for your new ebuild, and once you get it working you can post it with an upgrade request. Using the local ebuild route means that portage can manage the system consistently.

Good luck!

alright thanks guys.

i'll try writing my own ebuild and post it if I have any success...

The bochs 2.4.5 ebuild file add the PCI Host mapping feature by default but this feature require kernel 2.4 or 2.6.

As workaround I have modified the /usr/portage/app-emulation/bochs/bochs-2.4.5.ebuild file removing the "--enable-pcidev" compile time flag.
I have modified the original bochs-2.4.5.ebuild file in my local portage local directory, I do not know if this is the correct way to interact with portage system ....

The following file is the diff output where the bochs-2.4.5.ebuild.orig is the original file and the bochs-2.4.5.ebuild is the modified one.

Code: Select all

gentoo ~ # diff /usr/portage/app-emulation/bochs/bochs-2.4.5.ebuild.orig /usr/portage/app-emulation/bochs/bochs-2.4.5.ebuild
93d92
< 		--enable-pcidev \

Then you must recreate the Manifest file (containing the digest of bochs-2.4.5.ebuild file)

Code: Select all

gentoo ~ # ebuild /usr/portage/app-emulation/bochs/bochs-2.4.5.ebuild manifest
>>> Creating Manifest for /usr/portage/app-emulation/bochs

When you have set your preferred USE flags merge bochs-2.4.5 using ebuild command

Code: Select all

gentoo ~ # ebuild /usr/portage/app-emulation/bochs/bochs-2.4.5.ebuild clean
gentoo ~ # ebuild /usr/portage/app-emulation/bochs/bochs-2.4.5.ebuild merge

Have a nice day

alright thanks guys.

No need to. Just install the bleeding-edge overlay.

Linux has a workaround specifically for broken old software like this:

Code: Select all

setarch `uname -m` --uname-2.6 emerge bochs
