[9fans] plan 9 software for unix

[Russ Cox]

http://pdos.lcs.mit.edu/~rsc/software
has convenient packagings of libfmt,
libbio, libregexp, and mk that should build
on unix systems with minimal efforts.
i wrote freebsd/386 and linux/386 make files
and would welcome others.

the libraries are intended to integrate well
with the native unix c library, so that they
can be used in unix programs (rather than
just ports of plan 9 programs).

they're all in tgz, rpm, and freebsd ports formats.
enjoy.

libbio compiles a.o.k. on SunOS-sun4u with the Linux makefile (using
GCC. I dont have a spro licence).
libregexp9-10 compiles fine.

With libfmt I get a warning:
    gcc -Wall -Wno-missing-braces -Wno-parentheses -Wno-switch -O2 -g -c
fltfmt.c
    fltfmt.c: In function `xdodtoa':
    fltfmt.c:180: warning: implicit declaration of function `isinf'
which manifests later when linking:
    blueberry.north_ % make test
    gcc -o test test.c libfmt.a
    Undefined                       first referenced
     symbol                             in file
    isinf                               libfmt.a(fltfmt.o)
    ld: fatal: Symbol referencing errors. No output written to test
    collect2: ld returned 1 exit status
    make: *** [test] Error 1
    blueberry.north_ %

Apparently Solaris 2.9 doesn't have isinf in its libc. It does, however,
have
isnan() and finite(). finite() returns TRUE(1) if the argument is
neither infinity nor
NaN. isnan() returns TRUE if the argument is NaN. Therefore,
    if(finite(x) == FALSE && isnan(x) == FALSE) {
        // infinite found
    }

I guess you could ifdef a macro in based on underlying architecture in
the source and
-Dx in the Makefile, but, it seems very non-plan9 to be so crude for
just one function.
Then again, creating an external dependency file seems crude for one
function as well...

Stuff like that is annoying, but easy to work around if you have access
to the libraries that come with workshop (nevermind the workshop compilers,
which are the big deal).  I did this:

	gmake
	ld -r -o _fltfmt.o fltfmt.o /opt/SUNWspo/WS6U2/lib/libsunmath.a
	mv _fltfmt.o fltfmt.o
	gmake test

That fixed my libfmt.a.  Of course, if you don't have access to the
workshop libraries, you're still out of luck.

Cool!

I downloaded the RPMs to my Redhat 8 box, and the mk RPM did not work
for me  (I suspect the dependency on libregexp was looking for regexp,
and not regexp9, but have not had the time to check it out yet.)

I compiled the source in the tgz file, and it succeeded without warnings.

Incidentally, it appears that newer versions of rpm have seperated the
creation function to another executable named 'rpmbuild'.  I made the
following changes in my copy of the makefile:

RPMBLD=rpmbuild
RPMDIR=/usr/src/redhat

[...]

rpm:
         make tgz
         cp mk-$(VERSION).tgz $(RPMDIR)/SOURCES
         $(RPMBLD) -ba rpm.spec
         cp $(RPMDIR)/SRPMS/mk-$(VERSION)-1.src.rpm .
         cp $(RPMDIR)/RPMS/i586/mk-$(VERSION)-1.i586.rpm .


I don't have the rpm.spec, so the 'rpm' build target still isn't fully
functional yet. I'm happy enough that mk is working, so I'm setting this
aside, but I figured I had enough feedback to make worth sending out a note.

This was an embarrassing oversight on my part.
I provided (a portable!) __isInf and __isNaN in nan64.c
but didn't rewrite fltfmt to use them.

There are updated packages on the web pages.

In the interests of keeping down the number of versions,
I'm willing to remove the material from netlib and point
to your mit directory, if that makes you editing life
easier.  Or we can move it to someplace else on the
Plan 9 web server.

Just to clarify, too:  I'm not mandating that there be
a single version.   If the difficulties in getting portable
code to compile everywhere pushes us to have a few versions,
so be it.   I just have a desire to minimize confusion.

Great to have mk in a cleanly packaged form, not so great to have it as GPL.

let's not start this war.

Re: [9fans] plan 9 software for unix

[Russ Cox]

thanks to everyone who sent reports about building
on other systems.  i've incorporated the various
fixes and also put utf support back in.  there are
new packages on the web page.

Caught again by Reply-To...

I intended to send that last message just to Russ.
The context is that we're trying to avoid having too
many differing versions of libfmt, etc. floating around.
