Message  ERROR: Can't locate utf8.pm in @INC is related to perl and its use of the utf8 pragma.

In this case,  trying to run a session on Solaris could come up with error:

HELLO NXSERVER - Version 3.2.0-11 - SES Evaluation
NX> 105
NX> 598 an unrecoverable exception occurred, a complete log of the error can be found in your system logs.

The logs report errors similar to:

NXSERVER-3.2.0-11[6930]: [ID 702911
user.info] ERROR: ED4645DE EGIN failed--compilation aborted

Two possible workarounds are:

• Switch to POSIX  rather than use language settings in the utf8 format.
• Create a wrapper for nxserver/nxnode which will unset LANG and LC_ALL variables and then run the nxserver/nxnode binaries.

Wrapper example:

Two wrappers need to be written for nxserver and nxnode.

- To create an nxserver wrapper execute the following command:

    mv /usr/NX/bin/nxserver /usr/NX/bin/nxserver.bin

Next you should create a /usr/NX/bin/nxserver shell script which
contains:

    #!/bin/sh
      unset LANG
      /usr/NX/bin/nxserver.bin "$@"

Then set correct permissions as:

chmod 0755 /usr/NX/bin/nxserver
chmod 0755 /usr/NX/bin/nxserver.bin

- The same procedure should be carried out for nxnode. First rename the binary to:
   
    mv /usr/NX/bin/nxnode /usr/NX/bin/nxnode.bin

Create a /usr/NX/bin/nxnode shell script which contains:

    #!/bin/sh
    unset LANG
    /usr/NX/bin/nxnode.bin "$@"

Then set correct permissions as:

    chmod 0755 /usr/NX/bin/nxnode
    chmod 0755 /usr/NX/bin/nxnode.bin

- Next the suided scripts need to be modified accordingly. Since the binaries were changed from nxnode to  nxnode.bin, we need to modify two scripts.

Changes in /usr/NX/scripts/restricted/nxlicense.sh

line 27:

    if [ "$command" != "$NODE_ROOT/bin/nxnode" ];

should be:

    if [ "$command" != "$NODE_ROOT/bin/nxnode.bin" ];

Changes in  /usr/NX/scripts/restricted/nxtmpperm.sh line 35:

    if [ "$command" != "$NODE_ROOT/bin/nxnode" ];

should be:

    if [ "$command" != "$NODE_ROOT/bin/nxnode.bin" ];

If you need to set the LANG variable for a Gnome  or KDE desktop environment, then you will have to create a wrapper also for the desktop session.

Example:

In the node.cfg there is the following KEY:

CommandStartGnome="/usr/NX/scripts/gnome.wrapper.sh"

where you should place the wrapper which will then set the variable and
run Gnome directly.

In this file, write the shell script:

#!/bin/sh

export LANG="en_US.utf8"
gnome-session

chmod 755 /usr/NX/scripts/gnome.wrapper.sh

Note: example below is only a guide to how a wrapper could be implemented to fix this specific PERL problem.
