I've been trying to build the EPICS 3.14.7 Base on a i586-suse-linux system
using gcc 4.0.2, GNU Make 3.80, and Perl 5.8.7. After after many hurdles I've
finally hit a brick wall.

I followed the linked Wiki build instructions
(http://www.aps.anl.gov/epics/wiki/index.php/HowToPC104) and was confronted
with an error in which lcurses would not be found. After consulting a web fix,
this was fixed by changing lcurses to lncurses in
base-3.14.7/configure/os/CONFIG.Common.linux-x86. Unfortunately, due to lack of
foresight, I've lost the website URL for this fix, but it seemed to solve the
problem nicely.

When I gave the make command I then received errors of the following type:

./../../../src/cas/generic/casdef.h:513: error: ISO C++ forbids declaration of
'casPVI' with no type
../../../../src/cas/generic/casdef.h:513: error: expected ';' before '*' token

This time I consulted the Mantis bug database and found a patch for this problem
(http://www.aps.anl.gov/epics/mantis/view_bug_page.php?f_id=0000216). The patch
involved adding forward declarations of several class types to several C++
header files.

Although the patch got rid of the error messages above, I am now getting the
following error messages when I try to build:

I cannot seem to find any patches or advice for these errors and am at a
complete loss.
Can anybody help?!

Many thanks
