You must find out where is [and why is] 'getpagesize' in your environment.
For instance, on amd64 it is undefined in vgpreload_memcheck-amd64-linux.so:
000000208a28 000200000007 R_X86_64_JUMP_SLO 0000000000000000 getpagesize + 0
2: 0000000000000000 0 NOTYPE GLOBAL DEFAULT UND getpagesize
79: 0000000000000000 0 NOTYPE GLOBAL DEFAULT UND getpagesize
but defined in /lib64/libc.so.6:
873: 0000003d25ed8e80 23 FUNC WEAK DEFAULT 12
getpagesize@@GLIBC_2.2.5
1796: 0000003d25ed8e80 23 FUNC GLOBAL DEFAULT 12
__getpagesize@@GLIBC_2.2.5
1977: 0000000000000000 0 FILE LOCAL DEFAULT ABS getpagesize.c
5027: 0000003d25ed8e80 23 FUNC LOCAL DEFAULT 12 __GI___getpagesize
6204: 0000003d25ed8e80 23 FUNC WEAK DEFAULT 12 getpagesize
6768: 0000003d25ed8e80 23 FUNC GLOBAL DEFAULT 12 __getpagesize
On amd64, then either memcheck actually does not call getpagesize(), or libc
supplies a definition. Apparently in your environment memcheck does call
getpagesize, but you get a complaint that memcheck cannot see any definition
for it.
Therefore, add the obvious definition to vgpreload_core-arm-linux.so
and vgpreload_memcheck-arm-linux.so. Specifically, insert:
int getpagesize() { return 4096; }
into appropriate source file(s), then re-make valgrind until there is no more
"UND getpagesize".
Alternatively, figure out what valgrind/config.h.in is doing with
HAVE_GETPAGESIZE,
then change so that it reflects reality for your _runtime_ environment. Again,
re-make valgrind until there is no more "UND getpagesize".
