[9fans] Compiling links

[csant]

Hola,

I was trying to compile links, but it returns me an error and finishes  
with:
	pcc -I. -Ijpeg -Ipng -Izlib -B -p -c -DPLAN9 -DHAVE_CONFIG_H  
-D_RESEARCH_SOURCE -D_POSIX_SOURCE plan9.c
	/sys/include/ape/u.h:4[stdin:15] not a function
	/sys/include/ape/u.h:4[stdin:15] syntax error, last name: header
	pcc: cpp: 8c 490: error
	mk: pcc -I. -Ijpeg ...  : exit status=rc 487: pcc 489: cpp: 8c 490: error
I had previously built links on another system (installed from the same CD  
with the 2006-03-25 image) *before* pulling an update - this time I tried  
compiling it *after* the pull.

Pointers on how to fix this are welcome :) Also: what would be the most  
elegant way to build links using the old ape from /n/dump ? I could copy  
over all files, but that seems a bit silly. How do I do this in a nice way?

Plumb it. You will see an #ifndef which is true, producing a syntax error. The compiler is right.
Supply a -D_WHAT_EVER in the makefile will fix this.

add -D_PLAN9_SOURCE to the CFLAGS in mkfile. i'll have to see what got
changed and will update in /contrib shortly.

Many thanks :)
-D_PLAN9_SOURCE in the mkfile fixed it.

do
	mkdir /tmp/ape
	bind -bc /n/dump/xxxx/xx/sys/src/ape /tmp/ape
	mkdir /tmp/ape/cmd
	bind -bc /n/dump/xxxx/xx/sys/src/ape/cmd /tmp/ape/cmd
	etc...

then you can do:
	cd /n/dump/xxxx/xx/sys/src/ape
	mk install

I always meant to write a virtual fileserver that would create
the directories in /tmp on demand, but never got round to it...

I know of lib9.h, regexp.h, bsd.h, unistd.h & fcntl.h. (the latter are POSIX_SOURCE)

Thanks. I tried figuring out where the UA string gets defined, since links  
on Plan 9 has a broken UA string:
	Links Plan 9 4 i386; plan9)
but couldn't figure out where it gets it wrong.

% 9fs dump
% bind /n/dump/2006/0730/sys/src/ape /sys/src/ape
% divergefs -p /tmp/ape-build /sys
% cd /sys/src/ape
% mk install

You may wish to start up additional divergefs's for, e.g., /$objtype,
which the "mk install" will try to write into--or not, depending
on your purpose.
