Hello,<br><br>I get an error when trying to compile latest MonetDB default branch on my Ubuntu 10.04 64bit machine.<br><br>bootstrap: OK<br>configure (../configure --prefix=/opt/MonetDB/ --enable-monetdb5 --enable-sql --enable-rdf --enable-geom --enable-bits=64 --enable-debug --enable-datacell): OK<br>
make -j2: ERROR<br><br>The error is:<br>../../gdk/<a href="http://gdk_batop.mx">gdk_batop.mx</a>: In function ‘BATsetprop’:<br>../../gdk/<a href="http://gdk_batop.mx:2890">gdk_batop.mx:2890</a>: error: not protecting function: no buffer at least 8 bytes long<br>
<br>I think flags -fstack-protector-all and  -Wstack-protector are to blame, they default to 8 bytes. <br>I can skip the problem if I set 8 byte long dummy buffers to EVERY function that<br>doesn&#39;t have such a buffer, e.g., char mybuf[8];  memset(buf, 0, sizeof(buf));<br>
<br>I also thought of setting the buffer size to 1, by passing --param spp-buffer-size=1 as a compiler option, but then I get various other<br>errors.<br><br>gcc version:<br>gcc (Ubuntu 4.4.3-4ubuntu5) 4.4.3<br>Copyright (C) 2009 Free Software Foundation, Inc.<br>
