This seams to be a very common problem for some reason.

The linker needs to locate the RT shared library 'libhtcobol.so.0'.

The TC configure will install to a prefix='/usr/local' by default, so
the shared library 'libhtcobol.so.0' should be located in the
'usr/local/lib' directory.

Unfortunatly, some of the distributions do not use the 'usr/local ...'
directories, thus the linker is not set up to search that path.

So you can you can do either of the following:

1) Set the 'LD_LIBRARY_PATH' enviroment variable (bash: export
LD_LIBRARY_PATH=usr/local/lib), which is a temporary solution.

2) Use the 'ldconf' command to add the path to the linker search path.

3) Configure TC using the `--prefix=/usr' option, then compile and
install it.

The test suite on version 0.63 is set up to expect to find the compiler,
RTL and resouce files in the source code sub-directories above the
'test_suite' directory (i.e. ../compiler, ../lib, etc.).

So it is best to just configure and compiler TC, then run the test suite.
Otherwise, modifications to the perl script are required.

Hint: Before you run the test suite, remove the RT shared library (and
links) or compile the RTL a static library only.

Hope this helps.
