[lttng-dev] Compilation error with openwrt and uclibc 0.9.31

Thu Sep 26 11:58:22 EDT 2013

Hi again,

I was able now to build lttng-ust but I have still some problems with 
lttng-tools...

My current story is ( Could be usefull for the next guy which want to 
try to compile the tool with a toolchain from Jurassic time) :

* shm_open issue
   -> patch for toolchain uClibc-0.9.30.1 : 
http://lists.uclibc.org/pipermail/uclibc/2009-February/041886.html

* epoll_create1 and EPOLLRDHUP issue
   -> patch for toolchain uClibc-0.9.30.1 : 
http://uclibc.10924.n7.nabble.com/PATCH-Implement-epoll-create1-and-epoll-pwait-system-calls-td268.html

* be32toh issue
   -> patch for toolchain uClibc-0.9.30.1 : 
http://lists.uclibc.org/pipermail/uclibc/2010-June/044107.html

* pthread-condattr issue
    -> patch for toolchain uClibc-0.9.30.1 : 
http://www.mail-archive.com/uclibc@uclibc.org/msg01909.html

My last issue :

I found a bug here which seems related to my issue : 
https://bugs.lttng.org/issues/321
This bug talk about a fix in configure.ac : 
https://bugs.lttng.org/projects/lttng-ust/repository/revisions/faebb41808b9deda5ef5dfea0c035077407e7f9f/diff

Problem is that I seems to have already this fix in my lttng-ust 
version. I am not very confortable with autotools. Do I have to add a 
"libtool-linkdep-fixup" flag somewhere to be able to enable the fix 
during my compile process ?

Thanks,
Arthur.
