According to your debug message, libtest1.so requires "longjmp" symbol
for link itself. Error message about '(null)' must be replace with
"longjmp"
symbol name. In linker.c, sym_name variable is used to show symbol
name, but it is not assigned to valid value at this timing. The
following
initialization statement must be done before this error message.
sym_name = (char *)(strtab + symtab[sym].st_name);
Iliyan, could you also fix this problem ?
I assume that you need implicit linking specification for libc -
because
"longjmp" is included in this library.
