Hmmmm,
Using the git HEAD ust with the latest urcu git HEAD, the configure does
not fail on my side.
Basic questions, once you've installed liburcu (make && sudo make
install), have you done "ldconfig" ?

I am trying to compile the ust itself, and the ./configure step fails...
(liburcu compiled, I have the latest version, with the cds_list_add() in the
list.h, and it finds the library)
This is what I get:
checking whether cds_list_add(0, 0) is declared... no
configure: error: liburcu 0.5 or newer is needed, please update your version or
use LDFLAGS=-Ldir to specify the right location.
Any suggestions?
Thanks.

right way is to set the environment correctly.

Hi Daniel,
Yep, we are aware of that problem and will be fix in the next release.
Note that UST is not yet ready for the lttng-tools integration... This will
come in a very short term probably at release version 0.14. You can still use
basic trace command of lttng-tools to control UST.
But, for now, you can fix that quickly by changing this to
"libustctl/Makefile.am" from the git source of ust.
- $(top_builddir)/libustcomm/libustcomm.la
+ $(top_builddir)/libustcomm/libustcomm.la \
+ $(top_builddir)/snprintf/libustsnprintf.la
Recompile and install ust and should be fine :)
Don't hesitate for any other problems/comments.
Cheers
David

I'm trying to compile the latest lttng-tools (lttng-tools-9624336,
2011-05-04) and keep running into a weird error.
So far, ltt-control (cdfcd01, 2011-04-13), userspace-rcu 0.5.4 and ust
0.12 are downloaded from git.lttng.org, compiled and installed. I
download
lttng-tools-9624336 from the same source, run ./bootstrap without any
unusual results, but ./configure fails with:
checking for ustctl_connect_pid in -lustctl... no
configure: error: Cannot find libustctl. Use LDFLAGS=-Ldir to specify
its location.
The config.log hints at the problem's source:
configure:4421: checking for ustctl_connect_pid in -lustctl
configure:4446: gcc -o conftest -g -O2 conftest.c -lustctl -luuid -lpopt
-lpthread>&5
//usr/local/lib/libustctl.so: undefined reference to `ust_safe_snprintf'
collect2: ld returned 1 exit status
libustctl (.so.0.0.0, .so.0, .so, .a, .la) is in /usr/local/lib/ and
contains 'ust_safe_snprintf' in its hex code. Recall that UST 0.12
compiled without a hitch ('ust_safe_snprintf' appears in usterr.h,
ust_snprintf.h, snprintf.c, and tests/snprintf/prog.c, as fas as
source goes). Well, not completely true: for some weird reason,
/usr/local/lib/libust.so ended up containing these four
lines:
/* GNU ld script
Use the shared library, but the link with initializer too */
OUTPUT_FORMAT(elf64-x86-64)
GROUP ( libust.so.0 libust-initializer.o )
I replaced it with the expected symbolic link to
/usr/local/lib/libust.so.0.0.0 (the lttng-tools problem is the same
before and after this fix)
If it matters, I'm running a virtual Ubuntu 10.10 64-bits machine.
I'm at a loss as to how to fix this, and there's nothing on the Web
about this configure error (except a short thread on this very mailing list).
