Is there a way to inspect the current rpath on Linux?
For the record, here are a couple of commands that will show the rpath
header.
objdump -x binary-or-library |grep RPATH
Maybe an even better way to do it is the following:
readelf -d binary-or-library |head -20
The second command also lists the direct dependencies on other libraries followed by rpath
.
#include <stdio.h>
#include <elf.h>
#include <link.h>
int main()
{
const ElfW(Dyn) *dyn = _DYNAMIC;
const ElfW(Dyn) *rpath = NULL;
const char *strtab = NULL;
for (; dyn->d_tag != DT_NULL; ++dyn) {
if (dyn->d_tag == DT_RPATH) {
rpath = dyn;
} else if (dyn->d_tag == DT_STRTAB) {
strtab = (const char *)dyn->d_un.d_val;
}
}
if (strtab != NULL && rpath != NULL) {
printf("RPATH: %s\n", strtab + rpath->d_un.d_val);
}
return 0;
}
You can also use:
chrpath -l binary-or-library
