Add replacement for <a.out.h>
|
||
|
|
|
||
|
|
Valgrind includes <a.out.h> to get the definition of 'struct
|
||
|
|
nlist'. However, while glibc directly defines 'struct nlist' in
|
||
|
|
<a.out.h>, uClibc relies on it being defined by kernel headers (i.e
|
||
|
|
<a.out.h> simply includes <linux/a.out.h>). This works for most
|
||
|
|
architectures, but not for PowerPC, on which the a.out binary format
|
||
|
|
has never been supported, and therefore the <linux/a.out.h> kernel
|
||
|
|
header does not exist.
|
||
|
|
|
||
|
|
One solution would have been to use the <nlist.h> header, but this one
|
||
|
|
is only available in glibc, and it also has a slightly different
|
||
|
|
definition than the one in <a.out.h>. So, for the time being, the
|
||
|
|
easiest solution is to just replace the #include <a.out.h> in Valgrind
|
||
|
|
code by a copy/paste of the 'struct nlist' definition.
