Thanks for the clearification about statically link executables. How about
the message valgrind: m_ume.c: can't open interpreter
Since I don't know in detail how valgrind works in the backend, I only come
up that it comes from m_ume.c. Any idea on why it not capable to open the
intepreter (I'm assuming the interpreter is the one that will analyze the
executable?).
case PT_INTERP: {
char *buf = VG_(malloc)(ph->p_filesz+1);
Int j;
Int intfd;
Int baseaddr_set;
vg_assert(buf);
VG_(pread)(fd, buf, ph->p_filesz, ph->p_offset);
buf[ph->p_filesz] = '\0';
sres = VG_(open)(buf, VKI_O_RDONLY, 0);
if (sres.isError) {
VG_(printf)("valgrind: m_ume.c: can't open interpreter\n");
VG_(exit)(1);
}
intfd = sres.res;
