Hi,
I am trying to compile GCC from the CVS source code on a RedHat
GNU/Linux 7.2 Intel PC.
Specifically, I am having difficulty compiling the latest versions,
and I wish to learn how to compile newer versions without invoking
the whole make bootstrap procedure.
I built GCC 20020620 successfully using this procedure:
cvs -d :pserver:anoncvs@subversions.gnu.org:/cvsroot/gcc co -kk gcc
cd gcc;sudo mkdir /usr/local/gcc
./configure --prefix=/usr/local/gcc --enable-languages=c,c++,f77
make CFLAGS='-O' LIBCFLAGS='-g -O2' LIBCXXFLAGS='-g -O2 -fno-implicit-templates' bootstrap
sudo make install
Note the use of make etc. etc. bootstrap.
As I merge in updates to the GCC tree, using cvs update -kk,
what is the best way to rebuild GCC? Since the basic configure
has already been done is there a more time-efficient way to build
the latest daily snapshot?
e.g., would
make CFLAGS='-O' LIBCFLAGS='-g -O2' LIBCXXFLAGS='-g -O2 -fno-implicit-templates'
do the trick on all subsequent versions or should I always do
a ./configure and make bootstrap?
Thanks,
Charlie
