Re: [paho-dev] Build problem Eclipse PAHO C Client 
Hi Guy,
Paho is an open source project - generally we don't give absolute timescales for something to get fixed, after all you can always fix it yourself :-) You can also contribute fixes yourself (see the CONTRIBUTING.md file) through gerrit.
This is a small fix though -- just renaming the roundup function to Heap_roundup or similar. I can put that fix in the development branch tomorrow. 

When you've raised a bug, you should get emails when the status changes.

Hi Ian,

Yesterday I raised a bug for the build problem on OSX / IOS.
On what base (time frame) will the bug be resolved? And how can I keep (automatically) updated on the status?

Thanks.

Hi Al,

As mentioned when I prevent ("#undef roundup") that the (Apple) “roundup"
macro can replace the “roundup" occurrence in the the MQTT code everything
builds successfully except warnings (see below).

How can I log the bug (as you mentioned) for resolving this issue?

Thanks.

Guy,

This does seem to be a conflict on Apple platforms, looking at what I've
done here it seems I locally renamed roundup() in Heap.c to roundUp()
and changed all references to it in the Paho code. This is not ideal as
I'm now out of sync, and should be fixed in the code. Please open a bug
for it.
Apart from this is it now compiling ok for you?

As already mentioned there are 2 “roundup” entries a function in Heap.c

I thought during pre-processing the entries that redirect to macro’s

pre-processing the ‘roundup' entry in Heap.c tries to replace this by
'((((x) % (y)) == 0) ? \

understand the error messages I get when building my project.

How can I solve this/my problem?

In Heap.c

int roundup(int size)
{
    static int multsize = 4*sizeof(int);

    if (size % multsize != 0)
        size += multsize - (size % multsize);
    return size;
}

In param.h (#include <sys/param.h> in Socket.h)

#define    roundup(x, y)    ((((x) % (y)) == 0) ? \

The directory where you ran the script it should have created
a
directory called lib inside which you should see a
libcrypto_iOS.a
and
libssl_iOS.a that is a fat binary library for all iOS devices
including
the simulator, these two files should be added to your
project.
in that same directory should be a folder called include, you
can
either
add the this or the openssl directory inside it to your
project,
make
sure to configure your include path for your project to point
to
the
correct place, it should be the directory where the openssl
directory
is
as the #includes in the C client are for openssl/<file>

If you don't have a built copy of OpenSSL just remove the

If you want to include SSL support as well you a script like

You will need to edit the script in the project I linked to

The

Do these also work for IOS, since I'm trying to build
