Building the compiler is actually not that difficult. You just need to make sure that you get your options right when you run the "configure" command that generates the Makefiles (e.g., where to install it, what modules - compilers - to include with it, etc.). Once you determine what options you need, you run the configure command with the appropriate options, and that builds the Makefiles. You then run "make bootstrap" (or at least, that's what you used to do to build the compiler). That will take a while (it builds the compiler 2-3 times - once with your current compiler, then again with itself). Once it's built, you might be able to run "make test" to have it run its regression test suite, but you'd have to take a look at the current docs to see. After that, you run "make install", and it will install it.
If you do decide to do that, you probably don't want to overwrite your system compiler. I would recommend installing it either into another directory, perhaps something like /usr/local/gcc4 or somewhere under your home directory, if you'll be the only one using it. Using it after that is mostly a matter of making sure that the new compiler comes first in your PATH. For example, /usr/local/gcc4/bin:$PATH. That way, when you go to build things, it will use the new compiler instead of the system compiler. Otherwise, you may be able to find an RPM of the compiler for Red Hat. It's possible, though, that if you're on an older version of RedHat, and the build that you find was built for a newer version of RedHat, you could have issues with dependent libraries. If that's the case, your safest bet is to build it yourself. The primary difficulty you could run into while building it (if you decide to go that route), besides just determining the correct options, could be that it may require newer versions of some libraries and/or utilities on your system. If so, you would need to upgrade those as well. For example, certain versions of GCC require certain versions of GNU binutils. When you run the configure script, it will verify that you have usable versions of everything and will tell you if you don't, however. Lyle From: Action Request System discussion list(ARSList) [mailto:arsl...@arslist.org] On Behalf Of Marty.Thorin Sent: Thursday, August 20, 2009 3:24 PM To: arslist@ARSLIST.ORG Subject: Remedy API and gcc on Redhat Linux ** Good afternoon: I tried to compile the out-of-the-box program 'driver'. It compiled but would not link. When I asked BMC I was informed my copy of gcc (3.4.6) is too old and I need to upgrade to 4.4.1. I downloaded 4.4.1 today but it looks like I need to build the gcc compiler!?! This is not a small task. So I figure I must have done something wrong. Does anyone know where to download gcc 4.4.1 for Redhat in a tar or zip file?
