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.

Re: [9fans] Compiler Message
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.

Re: [9fans] Compiler Message

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?
Re: [9fans] Compiler Message
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.

Re: [9fans] Compiler Message
What about Drawterm on Mac? Is it working well? 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.

[9fans] The Third Button
Dear 9fans, Is there any situation (i.e., GUI area) where both the 2nd *and* the 3rd mouse button are indispensable options? Except for chording. Would it be possible to create the option of merging these two buttons for machines not blessed with the traditional rodent? I ask this because 3-button-mice (*not* 2-button-and-wheel) are almost impossible to find nowadays. Moreover, many notebooks have good touchpads to be used in situations when mice are impractical (on train, on the lap). These interfaces present pretty nice solutions for button-1 and button-3, but it's hard to impossible to do a button-2 click. In Acme, for instance, you generally need button-3 in the text area and button-2 in the menu area. I'm not sure when button-2 in the text area and button-3 in the menu area would be indispensable. In Rio, you generally need button-3 when you click outside the focused window and button-2 when you click inside the focused window. Cheers, Dante
Re: [9fans] The Third Button
In acme, button-3 can cancel a button-2 execute. Say you button-2-sweep a command, but then decide, err, no, don't want to do that, you chord-click button-3 to cancel the execution. Not sure about other ways of doing this.

Re: [9fans] The Third Button
with drawterm on osx, button 2 click is option+click, button 3 is command+click. in qemu, button 2 is shift+command+click and button 3 is command+click. on pc's with ps/2 two button mice, i believe shift+click is button 2. if you are using something different, try various combinations of modifier keys and clicking.
Re: [9fans] The Third Button
i forgot to mention: alternately, kbmap(3) is supposed to let you use function keys as mouse buttons.

[9fans] interleaved output of ratrace
hello, i'm trying to use ratrace to debug a go binary. what i don't understand is why records of syscalls sometimes appear on top of one another. here's the output of 'ratrace -c ./strings.test [2]/tmp/ratrace.log', where strings.test is made with 'go test -c strings'. http://sprunge.us/aCBG you can see in several places that more than one syscall record is printed on the same line. i find this quite odd since in /sys/src/cmd/ratrace.c:/^writer all output comes from a channel. i'm running this on 9front/amd64, but i'd appreciate if anyone can test on other systems. pgpGVESQjld0m.pgp Description: PGP signature
