MPFR and GMP have compiled OK with the libraries installed in .libs. I've even checked to make sure that the MPFR libraries were 64 bit, and now I've run out of ideas. I'd be really grateful for any help. I've tried rebuilding GCC four times now with the same result. Richard Richard - since this is still bugging you, I've come back to your original post. I notice one thing which nobody has mentioned: *when* you get this error, look at the *appropriate* config.log file [ gcc, like binutils, runs configure in multiple directories]. Even if this error happens/happened when running 'make', the error was within one of the configure scripts - gcc builds everything several times, and each time it configures the directories within it. Whenever configure fails (I usually point this out for cannot create executables messages), the key to understanding the problem is to find the appropriate config.log file, open that up in 'view' (or 'less'), search for 'a different ABI', and then look for the error messages in the lines before that. Probably, an error from gcc or ld. Once you have the error message, there are two possibilities: 1. it will indicate an error you made, and perhaps be blindingly obvious (I've had that when I was building for multiple archs and accidentally fell through to passing some ppc-only options in my CFLAGS :) - if so, please give the list a brief summary of what went wrong so that the next person who eventually does that can fix it. or, more likely: 2. Something new, which needs to be addressed. The ABI in the message reminds me of a past problem with gmp where, if CFLAGS were set, a processor capable of running 64-bit code would default to building 64-bit even though the rest of hte build was 32-bit. But, the variability in your results suggests this is not something easy like that. ĸen -- das eine Mal als Tragödie, das andere Mal als Farce Bruce - Can you help me with what I need to do to get gcc to recognize the mpfr source code in the root directory of gcc, cause its looking for the mpfr library, and not building the source code. gmp and mpc are building now. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

You may want to try to build gmp mpfr and mpc separately.

No problem building them, but gcc usually fails to find at least one of

I've already succeeded at building gmp, and mpc with in the gcc build
directory, I need to make mpfr, what do you suggest I do?
Is there a way to just build the following code block;
Needs #include mpfr.h
1. | int
2. | main ()
3. | {
4. | mpfr_t x; mpfr_init(x) ; mpfr_clear(x);
5. |
6. | ;
7. | return 0;
8. | }
and then re-run make?
After lfs is completed, there are the files /usr/lib/libmpfr.{a,so).
How about:
gcc -o xyz xyz.c -lmpfr
Works for me.
$ ldd xyz
linux-gate.so.1 (0xe000)
libmpfr.so.4 = /usr/lib/libmpfr.so.4 (0xb7735000)
libc.so.6 = /lib/libc.so.6 (0xb7584000)
libgmp.so.10 = /usr/lib/libgmp.so.10 (0xb751f000)
/lib/ld-linux.so.2 (0xb77a7000)
-- Bruce
I think I know what I'm doing wrong finally, all the command flags I'm
using to find mpfr are to find the mpfr library/header file, rather then
find the source to build the library.
What is the appropriate flag to tell gcc the source path rather then the
library path?
