Dear Malcolm,

I have also been trying to compile eclipse on an intel mac and have run into the same problem. The thing is that libtool does not know where gcclib.a is located. If you use g++ as the DYLD instead of libtool it does work, because g++ adds the path to the final link call.

However, after that I hit another problem that I myself have not been able to solve so far. At some point one reaches the make_icparc_solver. In it's makefile at some point the eclipse binary is called. However, it is not able to find libeclipse.dylib. I have not been able to find the problem on that one yet.

I decided to bite the bullet and try to compile Eclipse on my Intel  
Mac. Here's my progress so far:

Step 1) ./configure --build=powerpc-foo-darwin

This seems to be enough to convince 'configure' that I'm building on  
a PPC Mac, which is close enough for starters.

Step 2) Comiling sepia gives:

In file included from ../src/lex.c:54:
../include/rounding_control.h:335: error: parse error before '/' token
../src/lex.c: In function 'lex_an':

There is a stray */ on line 335 on rounding_control.h
Removing this line means sepia will compile, but:

Step 3) Linking sepia objects gives:

/usr/bin/ld: Undefined symbols:
_ec_fpu_round_orig_

This is because intervals.c has multiple definitions for  
ec_fpu_round_orig_ depending on your architecture, and it doesn't  
have one for Intel Macs. I just change line 162 from:

#elif defined(__POWERPC__) && defined(__APPLE__) && defined(__MACH__)
     int ec_fpu_round_orig_;

to:

#elif defined(__APPLE__)
     int ec_fpu_round_orig_;

This seems to do the trick

Step 4) When trying to build libeclipse.dylib there is a libtool error:

libtool: can't locate file for: -lgcc
libtool: file: -lgcc is not an object file (not allowed in a library)

Removed the -lgcc from line 1653 of configure:

     DYNLDFLAGS="-dynamic -single_module -flat_namespace -lgcc"

Step 5) Now libtool gives a different error:

/usr/local/lib/libgmp.a(add_n.o) has local relocation entries in non- 
writable section

This one has me stuck. Poking around the web seems to indicate that  
others have had this problem with libgmp on the Mac, but I cannot  
find any answers yet. It may be a fundamental problem with GMP.
