Wait a minute, -export-dynamic is an option to *ld* not to gcc!
Rewrite this line as
t-static: t.c libfoo.a
gcc -Xlinker -export-dynamic -o $@ t.c libfoo.a -L. -ldl
% rm ./t-static; make
% ldd ./t-static
libdl.so.2 => /lib/libdl.so.2 (0x40019000)
libc.so.6 => /lib/libc.so.6 (0x4001e000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
% make test
yellowpig% make test
LD_LIBRARY_PATH=. ./t-shared
test.
test.: test.:
LD_LIBRARY_PATH=. ./t-static
test.
test.: test.:
Anyway, if it is a bug in dlopen() or in some Makefile, then it is not a bug
in policy.
Cheers,
