Hi,
First thanks to Ian for the link below. I'm following up in this way in
case it is of any use to anyone else.

Ian
After consulting the link I did "make distclean" on the gmp, mpc and
mfrc installs that I pre-installed before trying to build gcc. I moved
the relevant directories under the top-level gcc source directory. On
the basis of the link I checked out config.log and found that I was
missing libelf (the source directory not libelf.h) so I installed
libelf-0.8.9. Crucially the libelf directory ended up in
/usr/local/include and not /usr/local. All it contains is the following:
-rw-r--r--. 1 root root 24540 2010-05-06 21:06 elf_repl.h
-rw-r--r--. 1 root root 5046 2010-05-06 21:06 gelf.h
-rw-r--r--. 1 root root 8133 2010-05-06 21:06 libelf.h
-rw-r--r--. 1 root root 1447 2010-05-06 21:06 nlist.h
-rw-r--r--. 1 root root 3888 2010-05-06 21:06 sys_elf.h
I then did configure and make again and it finished with:
lto/lto-elf.o: In function `lto_elf_file_open':
lto-elf.c:(.text+0xcb5): undefined reference to `elf_getshdrstrndx'
collect2: ld returned 1 exit status
make[3]: *** [lto1] Error 1
make[3]: Leaving directory

make[1]: Leaving directory `/home/mike/LLJVM/gcc/gcc-4.5.0/gcc-4.5.0'
make: *** [all] Error 2
so I guess it blew up in the linker. Stupidly I didn't check config.log
after I did the configure. Of course the object directory (gcc-obj-dir
in my case) was empty so I couldn't look at the config.log file to find
out what was wrong.
A little googling led me to the following thread:
http://gcc.gnu.org/ml/gcc/2010-03/msg00126.html,
http://gcc.gnu.org/ml/gcc/2010-03/msg00127.html and
http://gcc.gnu.org/ml/gcc/2010-03/msg00128.html which discusses using
elfutils-libelf 0.145 the relevance being the difference between
elf_getshstrndx and elf_getshdrstrndx the difference being that there is
an extra "d" in the latter. So then I installed
elfutils-libelf-0.145-1.fc11.i586.rpm and this is what I got:

[root@desktop gcc-obj-dir]#
You can see that rpm claimed that elfutils-libelf-0.145-1.fc11.i586.rpm
was already installed. A look at the source package
elfutils-0.145-1.fc11.src.rpm shows loads of files in the libelf
directory including gelf_xlatetom.c but a find on /usr revealed only:
[root@desktop LLJVM]# find /usr -name libelf -print
/usr/local/include/libelf
/usr/include/xulrunner-sdk-1.9.1/system_wrappers_js/libelf
/usr/include/xulrunner-sdk-1.9.1/system_wrappers/libelf
[root@desktop LLJVM]#
and a find on gelf_xlatetom.c revealed nothing:
[root@desktop SOURCES]# find /usr -name gelf_xlatetom.c -print
[root@desktop SOURCES]#
so I need to install the source package right but when I do something
like rpm -ivv <package-name> everything just ends up in one of the
/root/rpmbuild subdirectories and not where it's supposed to go. If I
need to install the source rpm can someone please tell me how to do it.
(I've never installed a source rpm before and the rpm manpage is not
helpful here.)
Being essentially stuck I decided to make another clean copy of the gcc
source dir and run config again from gcc-obj-dir. This showed two errors:
conftest.c:10:19: error: ppl_c.h: No such file or directory
conftest.c: In function 'main':
conftest.c:16: error: 'choke' undeclared (first use in this function)

A further look at config.log showed:
pplinc=''
ppllibs=''
so I decided I was missing ppllib. So then stupidly I installed
ppl-0.10.2-2.fc11.i586.rpm and got this when I did the rpm command:
package ppl-0.10.2-7.fc11.i586 (which is newer than
ppl-0.10.2-2.fc11.i586) is already installed
file /usr/bin/ppl-config from install of ppl-0.10.2-2.fc11.i586
conflicts with file from package ppl-0.10.2-7.fc11.i586
file /usr/lib/libppl.so.7.1.0 from install of
ppl-0.10.2-2.fc11.i586 conflicts with file from package
ppl-0.10.2-7.fc11.i586
file /usr/lib/libppl_c.so.2.1.0 from install of
ppl-0.10.2-2.fc11.i586 conflicts with file from package
ppl-0.10.2-7.fc11.i586
so I have to install the source rpm again right?
I still have no idea what the ac_nonexistent.h file is or whether the
source for libelf (from elfutils-libelf) and ppllib should be installed
under the top-level ggc source directory.
I'd be really grateful for any help. I hope I haven't forgot anything.
One last thing. Can someone point me to a document that documents how
the gcc build process works/is structured in some detail?
Cheers,
Mike
