[Monetdb-developers] Basics about MonetDB

by 叶亮

Hi, I'm a new comer with some questions about basic conceptions of MonetDB. 1. The executor I've ever found the executor of postgreSQL at src\backend\executor, but cannot make sure where it is like that in MonetDB src. MonetDB\MonetDB\src\gdk or MonetDB5-server\MonetDB5\src\mal ? 3. MAL MAL (MonetDB Assembly Language) is a script tool only for MonetDB or a common script language that can be applied to other softwares. Why it is a must in MonetDB ? 4. .mx files In MonetDB, .mx files are compiled to make .h and .c files generated.(in this way ?) Why is this routines ? (not just coding in .h and .c files directly) Yel ---- Best Regards richardroky(a)gmail.com

[Monetdb-developers] Concerning headless branch

by dsuh

I noticed a new headless branch that aims to replace BATs with COLs. Could you give me more information on COLs? Is what you are trying to achieve faster queries, less memory usage, or other advantages? Assuming that this is the new direction for MonetDB, do you expect that it will be merged with the Hg default tip for the next release after March 2011? Thanks. David Suh

[Monetdb-developers] libxml linking error during compilation, Mar2011 (Mac 10.6.6)

by Babis Nikolaou

Hi, do you have any idea about the following error: *** Warning: Linking the shared library lib_batxml.la against the loadable module *** lib_xml.so is not portable! *** Warning: lib lib_xml.so is a module, not a shared library *** And there doesn't seem to be a static archive available *** The link will probably fail, sorry Attached are the libtool's actions concerning the previous error. Furthermore, if it is relevant to my question, i provide the following information: MonetDB_Mar2011$ find . -name 'lib_xml*' ./monetdb5/extras/xml/.libs/lib_xml.la ./monetdb5/extras/xml/.libs/lib_xml.lai ./monetdb5/extras/xml/.libs/lib_xml.so ./monetdb5/extras/xml/.libs/lib_xml.so.dSYM ./monetdb5/extras/xml/.libs/lib_xml.so.dSYM/Contents/Resources/DWARF/lib_xml.so ./monetdb5/extras/xml/.libs/lib_xml_la-xml.o ./monetdb5/extras/xml/lib_xml.la ./monetdb5/extras/xml/lib_xml_la-xml.lo And last, i can assure you that there is a static library in my system for libxml (/usr/local/Cellar/libxml2/2.7.7/lib/libxml2.a) and the directory containing it has been included in the PKG_CONFIG_PATH explicitly (you can check this by inspecting the attached file). Thanks, Babis

[Monetdb-developers] Installation troubles Mac OSX 10.6.6

by Babis Nikolaou

Hi, what is going about this issue on Macs? Is there any progress? http://sourceforge.net/mailarchive/message.php?msg_id=26996821 I have managed to overcome all but the last problem concerning the AC_MSG_ERROR. The solution was to copy all .m4 files provided from the gettext package into the MonetDB build directory. Thanks, Babis

[Monetdb-developers] Installation troubles Mac OSX 10.6.6

by Jan Flokstra

Hello, I am trying to install the newest monetdb system with the single bootstrap/configure on my Mac. This does not work as good as it used to be. First when I do ./bootstrap I get the message that the libtoolize cannot be found. This is not installed on Mac OS, the default here is glibtoolize (version = 2.2.4). When using a package managers like fink libtoolize may be already installed in /sw because other packages need it. My solution was to temporary change the bootstrap file. The next problem is that it cannot find the libiconv package. I have libiconv installed in the monetdb prefix but i get the message: configure.ac:2255: error: possibly undefined macro: AM_ICONV When I remove this macro from bootstrap I get the message: configure.ac:152: error: possibly undefined macro: AC_MSG_ERROR This is a hard one because this is a standard macro, What could be wrong here? Jan Flokstra.
