I.  RedHat 7.1 Kernel: 2.4.2-2 gcc version: 2.96.20000731 

1. Installation of BLT library:

#cd swarm-2.1.1 
#./configure

complained about missing BLT library: when I try to install downloaded version of "blt-2.4c-1.i386.rpm" from somewhere on the Web, 

#rpm -i blt-2.4c-1.i386.rpm

complains about dependancy from libtcl8.0.so, libtk8.0.so, despite existing soft links 

/usr/lib/libtcl.so->/usr/lib/libtcl8.3.so
/usr/lib/libtk.so->/usr/lib/libtk8.3.so

and the same thing after creating :

/usr/lib/libtcl8.0.so->/usr/lib/libtcl8.3.so
/usr/lib/libtk8.0.so->/usr/lib/libtk8.3.so

'rpm -i' again complains;

THEN finally when gnome_rpm offers to ignore these dependencies (the system would become unstable ?!), I 
said: yes, make the system unstable, install BLT library and go away ... this time around ./configure went through but apparently Makefile-s are wrong.


2. Configuration and compiling process:
2.1
#make
...
cc1obj: warnings being treated as errors

and so on ... the package did not compile
