Richard Sahw, KF5OIM, reported a failure in the C++ test when attempting
to build an RPM package in a clean environment. This patch amends the
LD_LIBRARY_PATH in the generated shell scripts in the c++ and tests
directories.
Clean up various left over commented lines from dlopen to single
libhamlib transition. Remove unneeded configure variables.
Correct minor inconsistencies in Makefile.am files.
Define a new variable, READLINE_LIBS, so that only programs that offer
Readline support are linked against it.
Fix various compilation warnings and errors in test files revealed with
'make check' on MinGW.
Define rig and rotor backends to (mostly) be built in alphabetical
order.
Setting LD_LIBRARY_PATH for testcpp and testrig in the generated test
shell scripts corrects a long-standing bug that broke 'make check'.
Add Hamlib_design.eps to allow 'make dvi' to succeed when running
'make distcheck'.
Use the libtool link mode argument '-version-info' to set the Hamlib 3
ABI to be compatible with Hamlib 1.2 ABI. As the current ABI has not
been changed or removed, we should be able to maintain backward
compatibility. The libtool docs state that so long as the ABI is only
added to, backward compatibility should be maintained.
My idea here is to be able to have presently compiled programs be able
to use binary libraries of Hamlib 3 without recompiling. So far I have
tested this locally on Linux and Windows. More testing is welcome.
