Earlier Subject: Re: [LTP] ext4/e4defrag.c testcases compilation error,
Hi Garret/Miao,
On PPC systems, fallocate() seems to be already defined at
/usr/include/bits/fcntl.h,
so building EXT4 test cases on PPC64 machines will create build problems even
if the
pre-requisite packages:
e2fsprogs*
e2fsprogs-libs*
e2fsprogs-devel*
are present. So, this patch adds an extra check. Please let me know your
thoughts.
Errors bound to occur:
[
gcc -g -O2 -g -O2 -fno-strict-aliasing -pipe -Wall
-I/root/subrata/ltp/ltp-dev/testcases/kernel/include -I../../../../../include
-I../../../../../include -L../../../../../lib e4defrag.c -lltp -lm -o
e4defrag
e4defrag.c:388: error: conflicting types for âfallocateâ
/usr/include/bits/fcntl.h:240: note: previous declaration of âfallocateâ
was here
make[1]: *** [e4defrag] Error 1
]
