headless documentation
by Fabian Groffen 14 Mar '14

14 Mar '14

Hi devs, Is there any documentation for headless? Not that it seems completely pointless, but how exactly is it supposed to work? I'm looking for documentation that explains why, but preferably also old situation and how it should be converted into new situation kind of examples. Things like: can I simply insert into a void-headed BAT to automatically create a BAT with gaps if I e.g. insert 1, 5 and 7. Can I do a selection on the head (which should be a simple offset jump) to easily retrieve its tail, and how does the subselect interface exactly work. There appears to be not even comments on this piece of code. Regards from Fuerteventura, Fabian

FYI: they were pretending they had a GCC since OSX Lion. Fabian

Re: MonetDB: Jan2014 - configure: don't choke on deprecation messages
by Stefan Manegold 06 Mar '14

Hi Fabian, thank you very much for your fix! Do I understand correctly that the problem is in fact related to (recent versions of) MacOSX, and the packages / libraries that come with it, rather than the compiler itself? If so, we might want to consider adding option "-Wno-deprecated-declarations" only on (the respective versions of) MacOSX, --- or only when there is Apple's CommonCrypto API rather than OpenSSL, provided we can easily detect that --- rather than whenever using any version of clang on any system (and with old versions of gcc on any system). Yes, I still have the ambition to disable strict compilation checks only as selectively as possible, even on "odd" platforms ... ;-) Thanks!

This option sets flags for both the preprocessor and linker. This is typically something like _REENTRANT. On Mountain Lion, gcc/clang would set _REENTRANT. Same for CentOS 6. % /usr/bin/gcc -dumpspecs | grep pthread %{static:%{!dynamic:-D__STATIC__}}%{!static:-D__DYNAMIC__} %%{pthread:-D_REENTRANT} What I can imagine here, is that because clang on Mavericks now defaults to C99 mode (instead of gnu89 mode gcc defaults to) you get different defines and behaviour, possibly including _REENTRANT. A preprocessor check would have to give some facts around that. Fabian

status of default branch
by Fabian Groffen 05 Mar '14

05 Mar '14

Hi all, Since I'm no longer really in the loop with MonetDB, I was wondering what the state of the default branch is supposed to be. I just fixed a configure error and now hit a redeclaration problem regarding gdk.h and gdk_private.h. gdk_batop.c includes both headers so it seems like a valid complaint to me. Is OSX still a supported platform, these days? I guess there is little to no point in supporting it. Fabian

Building the ODBC driver on OS X 10.9.2
by Dimitar Nedev 04 Mar '14

04 Mar '14

Hello everybody, I managed to build the latest MonetDB version on my Mac with all default modules, excluding the DataCell and RDF, but the ODBC build fails. Trying to fix it I encountered several issues: A few libraries could not be found with the default build settings: hwcounters = no (no supported harwdware counters interface found) mseed = no (libmseed.h header not found) raptor = no (by default) readline = no (readline/readline.h does not contain rl_completion_func_t, is it GNU readline?) setsockopt = no (by default) sphinxclient = no (sphinxclient.h header not found) unixodbc = no (odbcinst.h not found) valgrind = no (by default) So far it makes sense, since unixODBC cannot be found, the ODBC driver cannot be built. Just that I've actually installed the library. Adding the following line: --with-unixodbc=/opt/local --with-sphinxclient=/opt/local --with-readline=/opt/local to point to some of the libs location appeared to fix the configuration: checking odbcinst.h usability... yes checking odbcinst.h presence... yes checking for odbcinst.h... yes checking for SQLGetPrivateProfileString in -lodbcinst... yes checking for SQLGetDiagRec in -lodbc... yes checking checking whether SQLColAttribute uses SQLLEN * or SQLPOINTER... using "SQLPOINTER" hwcounters = no (no supported harwdware counters interface found) mseed = no (libmseed.h header not found) raptor = no (by default) setsockopt = no (by default) valgrind = no (by default) Now, trying to build that configuration yields the following error: libtool: compile: gcc -DHAVE_CONFIG_H -I. -I../../../../clients/odbc/driver -I../../.. -I../../../../clients/odbc/driver -I../../mapilib -I../../../../clients/odbc/driver/../../mapilib -I../../../common/options -I../../../../clients/odbc/driver/../../../common/options -I/opt/local/include -DLIBMONETODBC -g -O2 -I/opt/local/include -c ../../../../clients/odbc/driver/SQLColAttributes.c -fno-common -DPIC -o .libs/libMonetODBC_la-SQLColAttributes.o ../../../../clients/odbc/driver/SQLColAttribute.c:243:1: error: conflicting types for 'SQLColAttribute' SQLColAttribute(SQLHSTMT StatementHandle, ^ /opt/local/include/sql.h:609:24: note: previous declaration is here SQLRETURN SQL_API SQLColAttribute(SQLHSTMT StatementHandle, ^ ../../../../clients/odbc/driver/SQLColAttribute.c:272:1: error: conflicting types for 'SQLColAttributeA' SQLColAttributeA(SQLHSTMT StatementHandle, ^ /opt/local/include/sqlucode.h:377:19: note: previous declaration is here SQLRETURN SQL_API SQLColAttributeA( ^ ../../../../clients/odbc/driver/SQLColAttribute.c:290:1: error: conflicting types for 'SQLColAttributeW' SQLColAttributeW(SQLHSTMT StatementHandle, ^ /opt/local/include/sqlucode.h:29:19: note: previous declaration is here SQLRETURN SQL_API SQLColAttributeW( ^ 3 errors generated. make[7]: *** [libMonetODBC_la-SQLColAttribute.lo] Error 1 I am running: OS X 10.9.2 / Darwin Kernel Version 13.1.0 x86_64 Xcode 5.0.2 and gcc -v reports: Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn) unixODBC 2.3.1_0 installed from MacPorts 2.2.1 Any ideas?
