what do you have in configlog for LIBDL?
here it's all empty
LIBDL=''
LIBDL_PREFIX=''
LTLIBDL=''
if I add
+ --with-libdl-prefix=${STAGING_DIR_HOST}${prefix} \
+ --with-libpthread-prefix=${STAGING_DIR_HOST}${prefix} \
to EXTRA_OE_CONF (we already have couple of --with-*-prefix there) it's
found correctly (and this is at least better workarround then forcing
-ldl directly to LDFLAGS):
LIBDL='/OE/shr-core/tmp/sysroots/om-gta02/usr/lib/libdl.so'
LIBDL_PREFIX='/OE/shr-core/tmp/sysroots/om-gta02/usr'
LTLIBDL='-L/OE/shr-core/tmp/sysroots/om-gta02/usr/lib -ldl'
same problem is with libpthread..
maybe their m4/lib-link.m4 does something wrong in
AC_DEFUN([AC_LIB_HAVE_LINKFLAGS],
[
AC_REQUIRE([AC_LIB_PREPARE_PREFIX])
AC_REQUIRE([AC_LIB_RPATH])
I just looked at the code in lib/configure and concluded that its just
luck whether it figures out the correct values or does something really
nasty. Its poking about ${libdir} for this stuff so you end up with
something like the following combinations:
a) 64 bit system with 64 bit libs in /usr/lib64 and no 32 bit libs:
Finds no -ldl
Something else may or may not link it indirectly so the build may or
may not work.
b) 64 bit system with 64 bit libs in /usr/lib64 and 32 bit libs in /usr/lib,
building for 32 bit:
Finds a -ldl which works.
Things appear to work.
c) Other variations
The correct fix would appear to be to set the paths specifically using
the options Martin mentions above.
Cheers,
Richard
