gpsd cross-compile problem

Hello,
I try to compile gpsd for the Mini6410.
lsusb on the Mini:

Bus 001 Device 002: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial
Port

So I get the sources for gpsd, cd to gpsd and write an .scons-option-cache:
libgpsmm = False
libQgpsmm = False
python = False
prefix = '/workroot/output/staging/usr/'
target = 'arm-none-linux-gnueabi'
sysroot = '/workroot/output/staging/'

Run scons, I get:

/opt/FriendlyARM/toolschain/4.5.1/lib/gcc/arm-none-linux-gnueabi/4.5.1/../../../
../arm-none-linux-gnueabi/bin/ld:
crt1.o: No such file: No such file or directory

$ locate crt1.o
/opt/FriendlyARM/toolschain/4.5.1/arm-none-linux-gnueabi/sys-root/usr/lib/Mcrt1.
o
/opt/FriendlyARM/toolschain/4.5.1/arm-none-linux-gnueabi/sys-root/usr/lib/Scrt1.
o
/opt/FriendlyARM/toolschain/4.5.1/arm-none-linux-gnueabi/sys-root/usr/lib/crt1.o

/opt/FriendlyARM/toolschain/4.5.1/arm-none-linux-gnueabi/sys-root/usr/lib/gcrt1.
o
/usr/lib32/Mcrt1.o
/usr/lib32/Scrt1.o
/usr/lib32/crt1.o
/usr/lib32/gcrt1.o
/usr/lib64/Mcrt1.o
/usr/lib64/Scrt1.o
/usr/lib64/crt1.o
/usr/lib64/gcrt1.o

I added
/opt/FriendlyARM/toolschain/4.5.1/arm-none-linux-gnueabi/sys-root/usr/lib
to /etc/ld.so.conf und run ldconfig, but with the same result.

I set LIBRARY_PATH with now success.

What have I to do that the ld the crt1.o could find?

I worked on a 64 bit Gentoo, but the toolchain is working. I compiled
QT4.8.1 successful for the Mini.

Or is their a simple solution to get gps data without the gpsd?

Solved.

I added 
sysroot =
'/opt/FriendlyARM/toolschain/4.5.1/arm-none-linux-gnueabi/sys-root'
libdir =
'/opt/FriendlyARM/toolschain/4.5.1/arm-none-linux-gnueabi/sys-root/usr/lib'

to $gpsd_source/.scons-option-cache and the the linker found the right
libs.

hi..
i am trying to develop a toolchain for gcc for beagle board.
at the last step i am facing the error that crt1.o not found.

I tried to understand your artical but didn't get it.

[root@Mannu 4.5.1]# locate crt1.o
/usr/lib/Mcrt1.o
/usr/lib/Scrt1.o
/usr/lib/crt1.o
/usr/lib/gcrt1.o

.
.
locate gives me the above output..

where to add the crt1.o exactly..

Where did you get the error?
I added it to the configure script of the application I compiled.

this is my script for creating toolchain.
The part covered with * is done...
after that when i run make -j 2 ... then it gives the error that c can not
create executables.
.
.
my target is arm-linux.
.
when i run a command to execute a hello.c program by 

arm-linux-gcc hello.c

it gives me crt1.o not found
ld retrurns 1
.
