[lttng-dev] lttng-tools 2.9.0 build failures

[Thomas Petazzoni]

Hello,

In the Buildroot project, we recently updated to lttng-tools 2.9.0, and
we're experiencing two build failures:

 * With a uClibc based toolchain:

prog.c:24:15: error: 'LM_ID_BASE' undeclared (first use in this function)
  h1 = dlmopen(LM_ID_BASE, "libfoo.so", RTLD_LAZY);

   I believe dlmopen() is not implemented in uClibc and musl, so
   perhaps this should be handled in lttng-tools by making the code
   conditional.

   See
   http://autobuild.buildroot.net/results/d87/d8745ef5c8c7d71f993edf2a8f3f107d2d1b35fc/build-end.log
   for the full build log.

 * With a musl based toolchain:

In file included from health.c:26:0:
../../../src/common/defaults.h:370:1: error: unknown type name 'pthread_attr_t'
 pthread_attr_t *default_pthread_attr(void);

   See
   http://autobuild.buildroot.net/results/255/2556b3266b913964bea25c21d014f4b1b25b6808/build-end.log
   for the full build log.

Best regards,

Thomas
