For example we want the host system's libGL and this may be +in a non-standard location like /usr/lib/mesa. The only place the location is know +about is in the ld.so.cache of the host system. + +Since nativesdk has a simple structure and doesn't need to use a cache itself, we +repurpose the cache for use as a last resort in finding host system binaries. This +means we need to switch the order of 3 and 4 above to make this work effectively. + +RP 14/10/2010 + +Signed-off-by: Khem Raj <raj.khem@gmail.com> +--- + elf/dl-load.c | 16 ++++++++-------- + 1 file changed, 8 insertions(+), 8 deletions(-) + +diff --git a/elf/dl-load.c b/elf/dl-load.c +index fcb39a78d4..cde9fc2358 100644 +--- a/elf/dl-load.c ++++ b/elf/dl-load.c +@@ -2109,6 +2109,14 @@ _dl_map_object (struct link_map *loader, const char *name, + } + } + ++ /* try the default path. */ ++ if (fd == -1 ++ && ((l = loader ?: GL(dl_ns)[nsid]._ns_loaded) == NULL ++ || __builtin_expect (!(l->l_flags_1 & DF_1_NODEFLIB), 1)) ++ && __rtld_search_dirs.dirs != (void *) -1) ++ fd = open_path (name, namelen, mode & __RTLD_SECURE, &__rtld_search_dirs, ++ &realname, &fb, l, LA_SER_DEFAULT, &found_other_class); ++ /* Finally try ld.so.cache */ + #ifdef USE_LDCONFIG + if (fd == -1 + && (__glibc_likely ((mode & __RTLD_SECURE) == 0) +@@ -2167,14 +2175,6 @@ _dl_map_object (struct link_map *loader, const char *name, + } + #endif + +- /* Finally, try the default path. */ +- if (fd == -1 +- && ((l = loader ?: GL(dl_ns)[nsid]._ns_loaded) == NULL +- || __glibc_likely (!(l->l_flags_1 & DF_1_NODEFLIB))) +- && __rtld_search_dirs.dirs != (void *) -1) +- fd = open_path (name, namelen, mode, &__rtld_search_dirs, +- &realname, &fb, l, LA_SER_DEFAULT, &found_other_class); +- + /* Add another newline when we are tracing the library loading. */ + if (__glibc_unlikely (GLRO(dl_debug_mask) & DL_DEBUG_LIBS)) + _dl_debug_printf ("\n"); |
