======================================================= Frequently Asked Questions (FAQ) for PostgreSQL V7.0 SCO UnixWare and OpenServer Specific TO BE READ IN CONJUNCTION WITH THE NORMAL FAQ ======================================================= last updated: $Date: 2000/08/26 19:34:24 $ current maintainer: Billy G. Allie (Bill.Allie@mug.org) original author: Andrew Merrill (andrew@compclass.com) PostgreSQL 7.0 can be built on SCO UnixWare 7 and SCO OpenServer 5. On OpenServer, you can use either the OpenServer Development Kit or the Universal Development Kit. However, some tweaking may be needed, as described below. Topics: *) Skunkware *) GNU Make *) C++ and libpq++ *) Readline *) Using the UDK on OpenServer *) Compiling PostgreSQL using the UDK *) Reading the PostgreSQL man pages on UnixWare *************************************************************************** *) Skunkware You should locate your copy of the SCO Skunkware CD. The Skunkware CD is included with UnixWare 7 and current versions of OpenServer 5. Skunkware includes ready-to-install versions of many popular programs that are available on the Internet. For example, gzip, gunzip, GNU make, flex, and bison are all included. If you do not have this CD, the software on it is available via anonymous ftp from ftp.sco.com/skunkware. For UnixWare 7.1, this CD is now labeled "Open License Software Supplement". Skunkware has different versions for UnixWare and OpenServer. Make sure you install the correct version for your operating system, except as noted below. *************************************************************************** *) GNU Make You need to use the GNU make program, which is on the Skunkware CD. By default, it installs as /usr/local/bin/make. To avoid confusion with the SCO make program, you may want to rename GNU make to gmake. *************************************************************************** *) C++ and libpq++ I have not been able to build libpq++, the PostgreSQL C++ interface, with the UnixWare or OpenServer C++ compilers. By default, building PostgreSQL also builds the libpq++ interface. When that fails, it causes the entire build of PostgreSQL to fail. This is the problem if you see the following error message: "pgenv.cc", line 47: error: no default constructor exists for class "string" If you have this problem, you can disable building of libpq++ with the following configure option: configure --without-CXX *************************************************************************** *) Readline If you install the readline library, then psql (the PostgreSQL command line SQL interpreter) remembers each command you type, and allows you to use arrow keys to recall and edit previous commands. This is very helpful, and is strongly recommended. The readline library is on the Skunkware CD. The readline library is not included on the UnixWare 7.1 Skunkware CD. If you have the UnixWare 7.0.0 or 7.0.1 Skunkware CDs, you can install it from there. Otherwise, try ftp.sco.com/skunkware. By default, readline installs into /usr/local/lib and /usr/local/include. However, the PostgreSQL configure program will not find it there without help. If you installed readline, then use the following options to configure: configure --with-libs=/usr/local/lib --with-includes=/usr/local/include Putting this together with the no-C++ option above yields: configure --with-libs=/usr/local/lib --with-includes=/usr/local/include --without-CXX *************************************************************************** *) Using the UDK on OpenServer If you are using the new Universal Development Kit (UDK) compiler on OpenServer, you need to use different arguments to the configure program. First, you need to specify the "unixware" template instead of the default. Second, you need to specify the locations of the UDK libraries. Putting these together: configure --with-template=unixware --with-libs=/udk/usr/lib --with-includes=/udk/usr/include Putting these together with the no-C++ and readline options from above: ./configure --with-template=unixware --with-libs="/udk/usr/lib /usr/local/lib" --with-includes="/udk/usr/include /usr/local/include" --without-CXX *************************************************************************** *) Compiling PostgreSQL 7.0 with the UDK The program, backend/utils/adt/int8.c, tickles a compiler bug with in the following version of the C compiler: Optimizing C Compilation System (CCS) 3.2 08/18/98 (u701) If you encounter an error compiling backend/utils/adt/int8.c, please apply the following patch: ------------------------------8< CUT HERE >8------------------------------ *** ./src/backend/utils/adt/int8.c.orig Mon Apr 3 13:24:12 2000 --- ./src/backend/utils/adt/int8.c Mon Apr 3 13:28:47 2000 *************** *** 410,416 **** if (*arg1 < 1) *result = 0; else ! for (i = *arg1, *result = 1; i > 0; --i) *result *= i; return result; --- 410,416 ---- if (*arg1 < 1) *result = 0; else ! for (i = *arg1, *result = 1; 0 < i; --i) *result *= i; return result; ------------------------------8< CUT HERE >8------------------------------ *************************************************************************** *) Reading the PostgreSQL man pages on UnixWare By default, the PostgreSQL man pages are installed into /usr/local/pgsql/man. By default, UnixWare does not look there for man pages, so you will not be able to read them. You need to make the following changes to access the PostgreSQL man pages from UnixWare. 1) You need to modify the MANPATH variable in /etc/default/man. I use: MANPATH=/usr/lib/scohelp/%L/man:/usr/dt/man:/usr/man:/usr/share/man:scohelp:/usr/local/man:/usr/local/pgsql/man 2) Add a line that says '1sql' to /etc/default/manSection. 3) The man pages for SQL commands are, by default, placed in section 'l' (normally used for "l"ocal pages). UnixWare does not support the 'l' section. The solution I use is to move all these pages from section 'l' to a section named '1sql'. To following KSH script will perform the move and change the section names in the man page: ------------------------------8< CUT HERE >8------------------------------ #!/bin/ksh cd /usr/local/pgsql/man mv man1 man.1 mkdir man.1sql cd /usr/local/pgsql/man/manl for i in *.l do sed -e '/^\.TH/s/"l"/"1sql"/' \ -e 's/\\fR(l)/\\fR(1sql)/' $i >../man.1sql/${i%.l}.1sql done cd /usr/local/pgsql/man rm -rf manl /usr/ucb/catman -M /usr/local/pgsql/man 1 /usr/ucb/catman -M /usr/local/pgsql/man 1sql ------------------------------8< CUT HERE >8------------------------------ After running this script, you can view the man pages using the 'man' command. They will not be usable from the scohelp system. I am working on integrating the man pages into the scohelp system. When I generate a PostgreSQL package for UnixWare 7.x, the man pages will be integrated into the scohelp system. I have not tried using the PostgreSQL man pages on OpenServer. Volunteers??
