Hello again 9fans,

I'm also trying to compile hosted Inferno for OS X 10.9, all seems to go
well until the "mk install" giving this error message:

shanes-air-2:inferno-os boris$ PATH=`pwd`/MacOSX/386/bin:$PATH mk install
(cd lib9; mk  install)
cc -c -arch i386 -mmacosx-version-min=10.4 -Wno-deprecated-declarations

clang: error: unknown argument: '-mno-fused-madd'
[-Wunused-command-line-argument-hard-error-in-future]
clang: note: this will be a hard error (cannot be downgraded to a warning)
in the future
mk: cc -c -arch ...  : exit status=exit(1)
mk: for j in ...  : exit status=exit(1)
shanes-air-2:inferno-os boris$

Does anyone have any insight?

Many thanks!

Shane.

Apparently the "future hard error" is treated as an error.

It looks like clang does not understand the gcc argument
'-mno-fused-madd'. Only the developers of Inferno would know if
multiply-add for float caveat is really a requisite for Inferno.
So look if there is the equivalent in clang, and convert the
argument; or suppress it where it is defined in the mkfiles (perhaps
it is necessary for gcc, doing "things", and not necessary with
another compiler, so the compiled program will not exhibit any
problem).

Hi,

On OS X 10.9.x, gcc points to clang. I installed gcc-4.9.0 from source
(follow instructions on this page, for example:
<http://solarianprogrammer.com/2013/06/11/compiling-gcc-mac-os-x/> to
get a working gcc. I don't use a package manager on OSX these days, I
compile/install what I need, from source.)

I then edited mkfiles/mkfile-MacOSX-386 to point to the newly built
gcc (I called the gcc binary gcc-4.9.0). Here is the complete file.

Re: [9fans] Compiler Message

Hi Shane,

Removing the compile argument won't help (leads to errors somewhere 
else).
I think that the most expedient solution is Ramkrishnan's.

In order to catch this sort of errors, some sort of "continuous 
integration" would be needed.
I have no idea how this could be done without investing into a real Mac 
machine, which is costly.

I reported the error to the person shown in the Hg commits; there was 
unfortunately no response yet.
Does anyone know which is the proper channel to report issues with 
Inferno?

Shane, I'm just curious: did you try to install Inferno for reasons 
similar to mine (here below)?

In tried to install Inferno because I thought that it was the simplest 
way to access (at least the file system of) my Plan9 Raspberry Pi from 
my Mac.
The other solutions I tried are awkward:
1. Plan9 under Virtual Box (don't want to pay for VMWare/Parallels).
     Configured network card according to Richard Miller's suggestion.
     Boots, but sometimes it doesn't, requiring to restart the program.
     Network works only sometimes.
2. Plan9 from user space, installed over Brew.
     It works, but I don't see there any way to import (mount) the 
remote file system locally.

Cheers,
Dante

No, the reasons I attempted an install is because I have no experience
getting hosted Inferno to run in Plan 9, although I possess a couple of
stable Plan 9 VMs (when they can reach the network, they'll ping 8.8.8.8,
but not get any sites like sources or 9gridchan - to be fair, there seems
to be network problems on those sites at the exact times I want to do
something, as I can't mount sources from Mac9P either), and I wish to have
an ARM Inferno compiler to start compiling against the Parallella,
following the guide at lynxline blog, and the boot up process at
parallella.org. I am yet to try anything, I think I'll leave it to tomorrow
at this stage.

have you tried qemu?  plan9 works wonderfully as a guest.
network access is as reliable as your mac.

install macfuse and then you can use 9pfuse.  it works, though
it is a bit slow.

Q for Mac is horrible, dodgy software. Then again, I didn't build it from
source. The good thing is, it'll convert images just fine.

older versions probably.  i built qemu-1.7.0 from source before
2.0 was stable and have had no problems.  i own fusion, but i
prefer qemu since fusion occupies kernel memory (meaning an
idle vm cannot be swapped out), and it uses about 30% more
memory per vm than qemu does.

what problems did you have with it?

The older versions refused to run. I've not tried this version I downloaded
today, only the "qemu-img" inside the package which worked fine.

What about Drawterm on Mac? Is it working well?
This would require of course configuring a CPU server...

Using the ANTS CPU server image, and Drawterm-Cocoa.

yes.  i use drawterm from

http://code.swtch.com/drawterm

i compiled it to run under X since i have to run that beast
anyways, but there is also drawterm-cocoa which builds
and runs native under osx.

http://bitbucket.org/jas/drawterm-cocoa

> This would require of course configuring a CPU server...

if you want the full experience of plan9, that is a given.  it
is not hard to do; and once you have a cpu/auth server,
booting additional cpu servers is an incredibly trivial task.
