From: Philippe Proulx Date: Wed, 22 Nov 2017 22:56:36 +0000 (-0500) Subject: lttng-tools: fix build errors and warnings for musl/uClibc-ng X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9dd25fe977867a2e7ef1ba40c3cbd12953ecaf51;p=buildroot.git lttng-tools: fix build errors and warnings for musl/uClibc-ng Add 0001-Fix-detect-dlmopen-and-disable-corresponding-tests-i.patch to detect if dlmopen() exists and disable parts of the build accordingly if not. This fixes a bug when building with musl or uClibc-ng. Add 0002-Fix-src-common-pipe.h-include-sys-types.h-for-ssize_.patch to fix an #include bug when building with musl. Add 0003-Fix-warning-src-bin-lttng-utils.c-cast-incompatible-.patch to remove compilation warnings. All three new patches are in upstream's master branch as of this date and will be part of an eventual release.
