Re: cross compile gdb

[Ming Zhang <mingz at ele dot uri dot edu>]

Hi, Dan,
thx for u remind. Since I already compiled the toolchain without
--builduserland, I try to compile the ncurse and ptx stuff by

eval `cat arm.dat` `cat gcc3.3.1-glibc2.3.2.dat`  sh ptx.sh

here i modified the ptx.sh a bit to let it download the latest 0.4.0.tgz
instead the one from your site. after a while, i got a target directory
with some bin and lib.

then i began to compile a native arm gdb 6 by

export bash_cv_have_mbstate_t=yes
 
CC=arm-unknown-linux-gnu-gcc ./configure --target=arm-unknown-linux-gnu
--prefix=/root/crosstool-0.24/result/arm-unknown-linux-gnu/gcc-3.3.1-glibc-2.3.2/target --host=i686-pc-linux-gnu --build=i686-pc-linux-gnu

make

but always come to this error. i can not understand why since i already
set the --host.

------------------ 
Beginning configuration for readline-4.3 for i686-pc-linux-gnu
 
checking whether make sets $(MAKE)... (cached) yes
checking for i686-pc-linux-gnu-gcc... (cached) arm-unknown-linux-gnu-gcc
checking for C compiler default output... a.out
checking whether the C compiler works... configure: error: cannot run C
compiled programs.
If you meant to cross compile, use `--host'.
---------------------

can u or anybody figure it out? thx.
