My solution: amend scripts/regress-config and append this to the
configure command:
CC=/usr/local/bin/gcc34 \
CPP=/usr/local/bin/cpp34 \
CXX=/usr/local/bin/g++34
My alterations to autoconf/Make.common* did not affect the build
process. But now I have:
Man directory:
/usr/home/dan/src/BaculaRegressionTesting/bin
Data directory: /usr/share
C Compiler: /usr/local/bin/gcc34 3.4.6
C++ Compiler: /usr/local/bin/g++34 3.4.6
Compiler flags: -g -O2 -Wall
Linker flags: -O
Libraries: -lpthread
Regression tests have started. Let's see if we get any cores this
time. NOTE: the problem might be with libc, which was compiled with
gcc4... in fact, all of FreeBSD 7.x was compiled with gcc4... :)
The next step is to recompile FreeBSD 7.x with gcc3, install it, and
try the above again.
