2.0.svn compilation error in gdalserver.c

[saultdon]

I checked out the 2.0 branch at revision 29663.

Been getting a compilation error:

IS it the same report as ​https://lists.osgeo.org/pipermail/gdal-dev/2015-August/042381.html ? Which OS and compiler version ?

[saultdon]

Hi Even,

That looks like this is related - from what I can see, the errors look similar.

I'm on Arch Linux 64-bit:

% uname -a
Linux archasus 4.1.5-1-ARCH #1 SMP PREEMPT Tue Aug 11 15:41:14 CEST 2015 x86_64 GNU/Linux

And compiler is gcc 5.2.0:

% pacman -Qi gcc                                                                                                                        =95%
Name           : gcc
Version        : 5.2.0-2
...
