We strongly recommend to install into a target directory where there is no previous version of GCC present. ... Installation into a temporary staging area or into a chroot jail can be achieved with the command make DESTDIR=path-to-rootdir install where path-to-rootdir is the absolute path of a directory relative to which all installation paths will be interpreted. Note that the directory specified by DESTDIR need not exist yet; it will be created if necessary. ^^^^^ I think those very words caused me to think what I did was a correct way of isolating the compiler without affecting my existing one. "make" has finished (about 21 hours) and I ran: make check-target-libjava which produced: === libjava Summary === # of expected passes 2561 # of unexpected failures 6 # of untested testcases 6 Question: In light of the documentation quoted above, if I do not use the DESTDIR, then to install, should I simply run: make install and my previous use of --prefix=/usr/local/gcj will cause everything to go under /usr/local/gcj and not affect my existing gcc? I'm really nervous that running make install will cause it to supplant my existing GCC. I also want to make sure there is not an additional parameter that should be provided to assure isolation of this installation. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42409
