I'm trying to build 64-bit gcc-4.2.2 on Solaris 9, but I keep getting 32-bit files in the build. I've tried various values for --host, --target, CFLAGS, and LDFLAGS, but no joy. I modified GCC_FOR_TARGET right before running make, and finally got a 64-bit gcc/crt1.o, but then intl/config tried to make more 32-bit objects. I've looked around the documentation, and back through a couple of years of the mailing list without luck. Could someone please clue me in on how to tell gcc to be 64-bit?
I don't have a sparc machine here, but I believe most sparc-solaris builds support both 32-bit and 64-bit code. You get 64-bit code with -m64 and 32-bit code with -m32. So yes, you will have 32-bit files in the build even when building a gcc that emits 64-bit code. This isn't a problem.
If you want 64-bit code only, you can configure for sparc64-sun-solaris2.10 (or whatever Solaris version you have) and also specify --disable-multilibs to turn off support for the 32-bit libraries.
You might need to be more specific about what you want here. You want a gcc compiled as 64-bit code or a gcc that emits 64-bit code or both?
