Hi! I'm trying to compile a c++ project already running under Solaris
with the g++ 3.2.1 compiler.
Without to remove existing object files from the Solaris Workshop C++
compiler i get the following result:
$>make -f mymakegnu1 HCSmain
g++ -g -v HCSmain.cc -o HCSmain

Removing the object files created by Solaris it gets out a huge number
of warnings and errors, this time related to the source code.
Can somebody give me an idea what the problem can be?
