[1.5.0] Compile error on Debian Lenny

Unbound
1

Hello,

i´m trying to compile Unbound 1.5.0 for my old Debian Lenny box.
1.4.22 runs fine so far. OpenSSL is self-compiled - "OpenSSL 1.0.1j 15
Oct 2014". Kernel is stock - "Linux debian 2.6.26-2-686 #1 SMP Sun Mar
4 22:19:19 UTC 2012 i686 GNU/Linux" and GCC is 4.3.2.

$ export CFLAGS="-march=pentium3 -msse -O2"
$ ./configure --prefix=/opt/unbound --with-ssl=/opt/ssl --with-pthreads
$ make
[...]
./libtool --tag=CC --mode=compile gcc -I. -I/opt/ssl/include
-march=pentium3 -msse -O2 -pthread -o getentropy_linux.lo -c
compat/getentropy_linux.c
libtool: compile: gcc -I. -I/opt/ssl/include -march=pentium3 -msse
-O2 -pthread -c compat/getentropy_linux.c -fPIC -DPIC -o
.libs/getentropy_linux.o
In file included from compat/getentropy_linux.c:51:
/usr/include/linux/random.h:38: error: expected
specifier-qualifier-list before '__u32'
make: *** [getentropy_linux.lo] Error 1

The lines in random.h look like this:

struct rand_pool_info {
  int entropy_count;
  int buf_size;
  __u32 buf[0];
};

Is this something unbound should patch or related to the kernel? May
be it´s just a little issue. But as a non-C-programmer I have no clue :slight_smile:

PS: I just checked 1.5.1-rc1, too. No effect.

$ ./configure --prefix=/opt/unbound --with-ssl=/opt/ssl --with-pthreads

Debian does not store SSL in /opt/ hence why are you pointing there?

Also, why not simply backport the Debian package? That is, get the new
package from the repo (add source repo, apt-get source unbound,
dpkg-buildpackage -b...) ?

$ make

Seems you are missing a define somewhere. Likely a:
#define __u32 uint32_t

would likely save the day. Though that is something that should be
defined by the configure. Most very likely you simply do not have the
ssl libs there.

Greets,

Hi Jeroen, Saturas,

Does this patch alleviate the issue?

Yes.

Another guy recommended by mail to add this line in kernel headers
directly. This works, too. As expected.

Thank you very much. Unbound works again.
