GDB build failure from tip

GDB build failure from tip

[ANDY KENNEDY]

configure error:  expat is missing or unusable

After digging into it for a couple of hours, I found that this message
was a red herring.  This message comes from the native GDB build.

As it stands, it appears that the CC for the two builds are SWAPPED:

~/base_layer/build/toolchain/mips64/crosstool-ng$ file .build/mips64-LinuxBSP-linux-gnu/build/build-gdb-cross/gdb/gdb
.build/mips64-LinuxBSP-linux-gnu/build/build-gdb-cross/gdb/gdb: ELF 64-bit LSB  executable, x86-64, version 1 (GNU/Linux), statically linked, not stripped

Unless I way off (please let me know if that is the case), I'll be
sending a patch file for this fix tomorrow.

Andy

It be great if you could post your build.log, or at least some more information from it.

A while back I faced a, what seams to be, similar issue. I proposed a patch which was rejected, however we use it at work and I know it has worked for several other people so give it a try.

Hope it works,

Best regards,
Stefan

Looks like others that I have seen on various groups.

I don't think this will help in my situation.

The problem is that when I "file" the gdb for the cross,
it is x86_64.  The native doesn't build.

I thought the information I provided was enough...  Sorry about that!

For what it is worth, in the 300-gdb.sh, the test above was
_NATIVE_..., then the CC was set to TARGET, and vice versa:

Line 95:
        CC_for_gdb="${CT_HOST}-gcc ${CT_CFLAGS_FOR_HOST} ${CT_LDFLAGS_FOR_HOST}"
        LD_for_gdb="${CT_HOST}-ld ${CT_LDFLAGS_FOR_HOST}"
        if [ "${CT_GDB_CROSS_STATIC}" = "y" ]; then
            CC_for_gdb+=" -static"
            LD_for_gdb+=" -static"
        fi

Line 195:
        [ "${CT_TOOLCHAIN_ENABLE_NLS}" != "y" ] &&    \
        native_extra_config+=("--disable-nls")

        if [ "${CT_GDB_NATIVE_STATIC}" = "y" ]; then
            CC_for_gdb="${CT_TARGET}-gcc -static"
            LD_for_gdb="${CT_TARGET}-ld -static"
        else
            CC_for_gdb="${CT_TARGET}-gcc"
            LD_for_gdb="${CT_TARGET}-ld"
        fi

Thanks for the info, though!

Stefan,

Looks like I was seriously confused on the below...

So, I guess the below "CROSS_STATIC" means the gdb built
for the TARGET to run on HOST. . . 

This seems too confusing to me (and backwards).

Anyways, using your patch now and I found that it didn't work.

Thanks!

Andy

Stefan,

Thanks!  That did work (after I saved the file -- you didn't
tell me I had to make the change AND save the file ;)).
