[lttng-dev] LTTng-ust 2.4.0-rc4 build error with uClibc

[Woegerer, Paul]

Hi Santiago,

it looks like uClibc does not have proper support for dlinfo().

You have two options:

Switch to a different C library suitable for embedded systems that does
have proper support for dlinfo(): http://www.eglibc.org/home

Build without liblttng-ust-dl (simply remove it from the list of SUBDIRS
in the top-level Makefile.am) and accept that the following LTTng 2.4
feature is missing in your custom build:
http://git.lttng.org/?p=lttng-ust.git;a=blob_plain;f=doc/man/lttng-ust-dl.3;hb=HEAD


HTH,
Paul
