Follow-up:

Downloaded package does start up as expected on FreeBSD 8.4 amd64 and FreeBSD 9.2 amd64.

Compiled version of 11.17.9 has same crash on FreeBSD 10.0 amd64. Same error shows if compiled with clang 3.3 or gcc46.

Previous version (11.15.19) compiles and runs on FreeBSD 10.0 amd64.

Will attache more detailed logs shortly.

From: @drstmane

Jim,

do I understand the following correctly:

  • after installing MonetDB-11.17.9-x86_64-FreeBSD-8.2-bin.tar.bz2 on a "virgin" (wrt. MonetDB, i.e., no old versions or databases left behind) mserver5 starts fine (on a new virgin database) on FreeBSD 8.4 & 9.2 but fails as reported on FreeBSD 10.0

  • compiling both 11.15.19 (Feb2013-SP6) and 11.17.9 (Jan2014) from source tarballs works fine on FreeBSD10.0, however, starting the server on a new virgin database only works fine with 11.15.19 (Feb2013-SP6), but fails as reported with 11.17.9 (Jan2014)

?

Thanks!
Stefan

Yes. These tests were done on VirtualBox VM's for 8.4 and 9.2. For 10.0 they were done in a fresh jail on a 10.0-STABLE amd64 machine (r260997) and confirmed in a VirtualBOX VM running 10-0 RELEASE with a "GENERIC" kernel (FreeBSD freebsd-10.0-amd64 10.0-RELEASE FreeBSD 10.0-RELEASE 0 r260789: Thu Jan 16 22:34:59 UTC 2014 root@snap.freebsd.org:/usr/obj/usr/src/sys/GENERIC amd64)

Correct. These tests were also done in fresh jails. I only tested these on FreeBSD 10-STABLE amd64.

I did patch common/utils/mutils.c on BOTH versions to force compilation, without which an error is thrown during compilation:

libtool: link: cc -g -O2 -D_REENTRANT -o .libs/mserver5 mserver5.o monet_version.o -pthread -Wl,--export-dynamic ../../monetdb5/tools/.libs/libmonetdb5.so -L/usr/lib -L/usr/local/lib /root/MonetDB-11.15.19/gdk/.libs/libbat.so /root/MonetDB-11.15.19/clients/mapilib/.libs/libmapi.so -lreadline /usr/local/lib/libxml2.so -lz -llzma ../../gdk/.libs/libbat.so /root/MonetDB-11.15.19/common/stream/.libs/libstream.so /usr/local/lib/libiconv.so -lm -lbz2 -lkvm /usr/local/lib/libpcre.so -lssl -lcrypto -lumem -pthread -Wl,-rpath -Wl,/usr/local/lib

cc: error: linker command failed with exit code 1 (use -v to see invocation)
gmake[5]: *** [mserver5] Error 1

The same error is seen on both versions and the same patch allowed compilation of both versions.

The patch, as follows, had no effect on function of compiled versions of 11.15.19.

From: @sjoerdmullender

Closing since we now run mserver5 on FreeBSD 10.1 ourselved, and that seems to work.
Note, the distributed binaries are still built on an ancient FreeBSD system.
