Both Brat and GBRAHMS can be run using LinuxPPC on a Macintosh computer. The other programs used for BRAHMS may also work, but I have not tested them. This document presents the problems that I encountered in getting the main programs working and my (sometimes clunky) solutions.

Brahms uses AFS in conjunction with CVS to maintain the software repositories. AFS allows a user to do what looks like a remote mount of the disks on which the software resides. CVS is the program used to checkout and update the software. Unfortunately, the normal AFS is a proprietary program that has not been ported to linuxppc. There is, however, a free AFS implementation called "arla". This is documented at the main Arla web site:
http://www.stacken.kth.se/projekt/arla/.
The source can be downloaded from
ftp://ftp.stacken.kth.se/pub/arla
Arla works with a kerberos (IV) implementation called KTH-Krb to maintain secure communications (this is the klog stuff...). The link to find KTH-Krb is given on the Arla site and is:
The files that I ended up downloading to build Arla are:
Several patches are necessary to get these programs running. You should start with krb4 since arla will require access to the krb libraries.
Patch:
:Once Arla was built (the default build is into /usr/arla), I copied the two files
from the rcf machines (/afs/rhic/common/etc/) into /usr/arla/etc.
Start arla from su using the script:
/usr/arla/bin/startarla
At this point, switching back to normal user, it is possible to issue a klog as usual. I find that I sometimes (at least when using the powerbook) also need to issue a klog on rcf.rhic.bnl.gov for cvs access to the Brahms files. I don't know why the two tokens (one local and one on rcf) are needed.
Unfortunately, the port of root to linuxppc is being done with an older egcs compiler. Although this will run on a machine with the more recent compilers, there seem to be some clashes when using the libraries generated using the older compiler to link with Brat. I got around this by compiling the root source using the gcc 2.95.2 compiler.
Starting from the root home page
I first found and downloaded the most recent compiled libraries for the linuxppc platform (v2.24.04). I then downloaded and compiled the root src.
None of the standard Makefiles work cleanly with the newer compiler. I made my own architecture makefile, called it Makefile.linuxppc (in /src), and followed the standard directions using linuxppc for the achitecture. The makefile is as follows:

Unfortunately, this Makefile crashes at several locations where "hand fixes" are necessary:
extern "C" int initgroups(const char *name, unsigned int basegid);
In each case, I've allowed the make to fail, fixed the problem, and then continued with the make from where things left off.
I got CERNLIB (2000 version) running several months ago and so my memory may be faulty here. However, I don't remember this as being much of a challenge. There is a linuxppc build available from the cern repository. I am building the complete distribution from source using the makeall script found in the /mgr subdirectory. To build cernlib from source, the makeall script should be relocated to the /src directory. Also, the config files for Imake should be located in /src/config/. I believe I may have modified some of the files in the /src/config directory: I have fairly recent update dates on Imake.cf, linux.cf and linux-pmac.cf:

This occured to me when rootcint was looking for, but could not find, a glibc function soinit.c. The function, which is called when rootcint tries to write out an error does exist in glibc, so I'm not sure why is is not found. The function is called when rootcint tries to write out an error.
This message seems to be associated with fortran compiles where the appropriate libraries are not accessed or, as discussed above, when a fortran program is linked using g++ rather than g77. I have not had much trouble when using the recent libraries.
This is almost always because of an inconsistent use a the const argument. Most of the development work on BRAT is being done using the egcs compiler. This compiler issues a warning, but not an error, when it detects an inconsistent use of the const argument. The gcc 2.95.2 compiler exits with error status when it discovers this problem. The const error needs to be fixed before building the program with the 2.95.2 compiler.
