From 6d981a99c35fbbfdf90ff188c5dd6d1ac46b9353 Mon Sep 17 00:00:00 2001 From: "Stephanie J. Lockwood-Childs" Date: Fri, 16 Aug 2013 15:03:41 -0400 Subject: gentoo: support running tests under sandbox when glibc runs its tests, it does so by invoking the local library loader. in Gentoo, we build/run inside of our "sandbox" which itself is linked against libdl (so that it can load libraries and pull out symbols). the trouble is that when you upgrade from an older glibc to the new one, often times internal symbols change name or abi. this is normally OK as you cannot use libc.so from say version 2.3.6 but libpthread.so from say version 2.5, so we always say "keep all of the glibc libraries from the same build". but when glibc runs its tests, it uses dynamic paths to point to its new local copies of libraries. if the test doesnt use libdl, then glibc doesnt add its path, and when sandbox triggers the loading of libdl, glibc does so from the host system system. this gets us into the case of all libraries are from the locally compiled version of glibc except for libdl.so. http://bugs.gentoo.org/56898 --- Makeconfig | 2 +- iconvdata/run-iconv-test.sh | 2 +- nptl/tst-tls6.sh | 2 +- 3 files changed, 3 insertions(+), 3 deletions(-) diff --git a/Makeconfig b/Makeconfig index 1908f27..d3f6023 100644 --- a/Makeconfig +++ b/Makeconfig @@ -612,7 +612,7 @@ comma = , sysdep-library-path = \ $(subst $(empty) ,:,$(strip $(patsubst -Wl$(comma)-rpath-link=%, %,\ $(filter -Wl$(comma)-rpath-link=%,\ - $(sysdep-LDFLAGS))))) + $(sysdep-LDFLAGS)))) $(common-objpfx)/dlfcn) # $(run-via-rtld-prefix) is a command that, when prepended to the name # of a program built with the newly built library, produces a command # that, executed on the host for which the library is built, runs that diff --git a/iconvdata/run-iconv-test.sh b/iconvdata/run-iconv-test.sh index e23f60d..b722415 100755 --- a/iconvdata/run-iconv-test.sh +++ b/iconvdata/run-iconv-test.sh @@ -35,7 +35,7 @@ GCONV_PATH=$codir/iconvdata export GCONV_PATH # We have to have some directories in the library path. -LIBPATH=$codir:$codir/iconvdata +LIBPATH=$codir:$codir/iconvdata:$codir/dlfcn # How the start the iconv(1) program.
