I'm trying to build MonetDB default branch(HEAD) on Linux, and I have built buildtools, but when I go on with MonetDB, I met some trouble. When run the ./bootstrap under /MonetDB directory, it produces the following errors: [root@node1 MonetDB]# ./bootstrap automake 1.5 is 1.5 or newer. OK, unless you want to compile with Intel's icc (on Linux), which requires automake 1.7 or newer. autoconf 2.60 is 2.57 or newer. Good. libtool 1.5 is 1.4 or newer. Good. Python 2.5.1 is 2.0.0 or newer. Good. /root/monetDB/MonetDB/MonetDB /root/monetDB/MonetDB/MonetDB /root/monetDB/MonetDB/MonetDB/src /root/monetDB/MonetDB/MonetDB/src /root/monetDB/MonetDB/MonetDB /root/monetDB/MonetDB/MonetDB/src/common /root/monetDB/MonetDB/MonetDB/src/common /root/monetDB/MonetDB/MonetDB /root/monetDB/MonetDB/MonetDB/src/gdk /root/monetDB/MonetDB/MonetDB/src/gdk /root/monetDB/MonetDB/MonetDB /root/monetDB/MonetDB/MonetDB/conf /root/monetDB/MonetDB/MonetDB/conf /root/monetDB/MonetDB/MonetDB You should add the contents of `/usr/local/share/aclocal/libtool.m4' to `aclocal.m4'.

Any help would be appreciated. 2010-02-06 zhangyuan
