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

Thu Sep 26 12:34:02 EDT 2013

Hi Arthur,

No need to add any flag, if configure detect a bogus link_all_deplibs
value in your libtool.m4 it will automatically patch it. Relevant
configure output:

[...]
checking for occurence(s) of link_all_deplibs = no in ./config/libtool.m4... 3
the detected libtool will not link all dependencies, forcing
link_all_deplibs = unknown
[...]

Your issue is that ld cannot find shared objects such as libuuid,
liburcu*. Which flag did you use to cross-compile?

Thanks,

Christian
