OmniTTY error and Troubleshooting Steps:

Solution 1: rote-config: command not found (OR) rote-config not found in a path

[root@OmNiTTY-SKS]# wget http://prdownloads.sourceforge.net/omnitty/omnitty-0.3.0.tar.gz
[root@OmNiTTY-SKS]# tar -xzf omnitty-0.3.0.tar.gz
[root@OmNiTTY-SKS]# cd omnitty-0.3.0
[root@OmNiTTY-SKS omnitty-0.3.0]# ./configure
checking whether libROTE is installed... ./configure: line 1303: rote-config: command not found no rote-config not found in path. Is the ROTE library installed?
You can download it from http://rote.sf.net
[root@OmNiTTY-SKS omnitty-0.3.0]#
[root@OmNiTTY-SKS omnitty-0.3.0]# ln -s /usr/local/bin/rote-config /sbin/rote-config 
[root@OmNiTTY-SKS omnitty-0.3.0]# ./configure
[root@OmNiTTY-SKS omnitty-0.3.0]# make
[root@OmNiTTY-SKS omnitty-0.3.0]# su -c "make install"            #---Installed successfully#

Solution 2: libncurses.so.5: error adding symbols: DSO missing from the command line while installing omnitty.

[root@OmNiTTY-SKS]# tar -xzf omnitty-0.3.0.tar.gz
[root@OmNiTTY-SKS]# cd omnitty-0.3.0
[root@OmNiTTY-SKS omnitty-0.3.0]# ./configure
[root@OmNiTTY-SKS omnitty-0.3.0]# make

[root@OmNiTTY-SKS omnitty-0.3.0]# ln -s /usr/local/bin/omnitty /sbin/omnitty
[root@OmNiTTY-SKS omnitty-0.3.0]# su -c "make install"                #---Installed sucesfully#

Solution 3: OmniTTY make command: /lib64/libncurses.so.5: error adding symbols: DSO missing from command line

[root@OmNiTTY-SKS omnitty-0.3.0]# make

/lib64/libncurses.so.5: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
make: *** [omnitty] Error 1

#Found Solution :

Added -lncurses and -ltinfo in Makefile
Makefile looks like this :
omnitty: $(objects)
$(CC) $(CFLAGS)  -o omnitty $(objects) $(LDFLAGS) $(LIBS) -lncurses  -ltinfo

Solution 4: OmniTTY: error while loading shared libraries: librote.so.0

[root@OmNiTTY-SKS]# omnitty
omnitty: error while loading shared libraries: librote.so.0: cannot open shared object file: No such file or directory
