OpenACS docs are written by the named authors, and may be edited by OpenACS documentation staff.

Check suitability of previously installed TCL. Start Tcl (type tclsh or find it using which tclsh).
```
[root root]% info exists tcl_platform(threaded)
1
[root root]% info patchlevel
8.4.7
[root root]%
tclsh
info exists tcl_platform(threaded)
info patchlevel
```
If the first command returns anything other than 1, then Tcl is not threaded. If Tcl is threaded and the version is 8.4 or higher, then installing Tcl from source is optional.
Retrieve Tcl 8.4 (or higher). Download and install Tcl 8.4 from source
Note for Debian users: you can apt-get install tcl8.4-dev if you have the right version (stable users will need to add tcl8.4 to their sources.list file as described on the Install Postgres page). You'll have to use /usr/lib/tcl8.4/ instead of /usr/local/lib when you try to find the Tcl libraries, however.
If you have not installed Tcl already, download the latest Tcl version from Sourceforge
Debian: apt-get install tcl8.4 tcl8.4-dev and proceed to the next step. In that step, replace --with-tcl=/usr/local/lib/ with --with-tcl=/usr/lib/tcl8.4.
Remember that you have to be root if you want to follow these instructions. On macOS type sudo su - to become root.
Alternatively use curl -L -O instead of wget (especially on macOS).
```
[root root]# cd /usr/local/src
[root src]# wget http://heanet.dl.sourceforge.net/sourceforge/tcl/tcl8.4.9-src.tar.gz
[root src]# tar xfz tcl8.4.9-src.tar.gz
[root src]# cd tcl8.4.9/unix
[root unix]# ./configure --enable-threads
[root unix]# make install
[root root]# 
cd /usr/local/src
wget http://heanet.dl.sourceforge.net/sourceforge/tcl/tcl8.4.9-src.tar.gz
tar xfz tcl8.4.9-src.tar.gz
cd tcl8.4.9/unix
./configure --enable-threads
make install
      
```

Configure, compile and install AOLserver. Many people need to run more than one version of AOLserver in parallel. This section accommodates future upgrades by installing AOLserver 4 in /usr/local/aolserver40r9.
```
[root aolserver]# cd /usr/local/src/aolserver40r10/aolserver
[root aolserver]# ./configure --prefix=/usr/local/aolserver40r10 --with-tcl=/usr/local/lib/
[root aolserver]# make install
cd /usr/local/src/aolserver40r10/aolserver
./configure --prefix=/usr/local/aolserver40r10 --with-tcl=/usr/local/lib/
make install
```
If you are using gcc 4 or later, see http://openacs.org/forums/message-view?message_id=309814
If this is the only version of AOLserver in use, or is the default version, create a symlink. If not, then be sure to use /usr/local/aolserver40r10 instead of /usr/local/aolserver in the steps below and check both scripts and makefiles to ensure they use the correct path.
```
[root aolserver]# ln -s /usr/local/aolserver40r10 /usr/local/aolserver
```
Configure, compile and install the modules.
1. Install nscache
```
[root aolserver]# cd /usr/local/src/aolserver40r10/nscache
[root nscache]# make install AOLSERVER=/usr/local/aolserver
```
2. Install nsoracle (if you want to use Oracle)
```
[root nscache]# cd ../nsoracle
[root nsoracle]# make install AOLSERVER=/usr/local/aolserver
```
  OpenACS looks for the Oracle driver at /usr/local/aolserver/bin/ora8.so, but some versions of nsoracle may create nsoracle.so instead. In that case, you can symlink (ln -s nsoracle.so ora8.so) to fix it.
3. Install nspostgres (if you want to use Postgres)
```
[root nscache]# cd ../nspostgres
[root nspostgres]# export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/pgsql/lib:/usr/local/aolserver/lib
[root nspostgres]# make install POSTGRES=LSB ACS=1 INST=/usr/local/aolserver  AOLSERVER=/usr/local/aolserver
              
```
  If you get errors like:
```
nspostgres.c: In function `Ns_PgTableList':
nspostgres.c:679: warning: passing arg 3 of `Tcl_DStringAppend' as signed due to prototype
```
  then PostgreSQL is probably not in the standard location. The location of PostgreSQL is very dependent on which method was used to install it. To correct the problem, replace LSB with the path to the path to your PostgreSQL installation. Often this is /usr/local/pgsql.
  You can use the ldd command to verify that all libraries are linked in: ldd /usr/local/src/aolserver40r10/nspostgres/nspostgres.so
  If you run into problems with libpq.a do the following (and repeat the step above)
```
[root nspostgres]# ranlib /usr/local/pgsql/lib/libpq.a
```
  If you run into problems with the linker, edit the Makefile. Add -lnsdb to the MODLIBS var.
```
MODLIBS = -L$(PGLIB) -lpq -lnsdb
```
4. Install nssha1
```
[root nspostgres]# cd ../nssha1
```
  Now install nssha1:
```
[root nssha1]# make install AOLSERVER=/usr/local/aolserver
```
  If the make fails you will have to edit nssha1.c. Comment out the following 2 lines (lines 139-140):
```
// typedef unsigned int u_int32_t;
// typedef unsigned char u_int8_t;
```
5. Install tDOM
```
[root nssha1]# cd ../tDOM-0.8.0/unix
```
  Edit the CONFIG file. Uncomment the instructions meant for AOLserver 4, but edit it to look like this:
```
../configure --enable-threads --disable-tdomalloc
          --prefix=/usr/local/aolserver --with-tcl=/usr/local/lib
```
  Note that the location of the Tcl library may vary on different platforms (e.g. for Debian 3.0: --with-tcl=/usr/lib/tcl8.4)
  Now you can compile and configure tDOM
```
[root unix]# sh CONFIG
[root unix]# make install
```
6. Install TCLLIB
```
[root nssha1]# cd ../tcllib
```
  Configure and compile TCLLIB
```
[root unix]# ./configure -prefix=/usr/local/aolserver40r10
[root unix]# make install
```
Add a database-specific wrapper script. This script sets database environment variables before starting AOLserver; this allows the AOLserver instance to communicate with the database. There is one script for Oracle and one for PostgreSQL. They do not conflict. If you plan to use both databases, install both. Note that this section requires you to have OpenACS files available, which you can get through CVS, through a tarball, or by other means. You can come back to this section after you acquire the OpenACS code, but don't forget to come back. (Note to maintainers: this should be moved to the next page and integrated into the text there)
- Oracle
```
[root aolserver]# cd /usr/local/aolserver/bin
[root bin]# cp /tmp/openacs-5.9.0/packages/acs-core-docs/www/files/nsd-oracle.txt ./nsd-oracle
[root bin]# chmod 750 nsd-oracle
[root bin]#
cd /usr/local/aolserver/bin
cp /var/tmp/openacs-5.9.0/packages/acs-core-docs/www/files/nsd-oracle.txt ./nsd-oracle
chmod 750 nsd-oracle
```
- PostgreSQL
```
[root aolserver]# cd /usr/local/aolserver/bin
[root bin]# cp /var/tmp/openacs-5.9.0/packages/acs-core-docs/www/files/nsd-postgres.txt ./nsd-postgres
[root bin]# chmod 755 nsd-postgres
[root bin]#
cd /usr/local/aolserver/bin
cp /var/tmp/openacs-5.9.0/packages/acs-core-docs/www/files/nsd-postgres.txt ./nsd-postgres
chmod 755 nsd-postgres
```
You may need to edit these scripts if you are not using /usr/local/aolserver as the directory of Aolserver4.
Change startup script (optional). If you want to run AOLserver on a port below 1024 (normally, for a webserver you will use 80), you will have to change the /var/lib/aolserver/service0/etc/daemontools/run script according to the documentation found there (namely: Add the -b yourip:yourport switch)
Test AOLserver.
