maemo scratchbox compiler error with gtk+-2.0

Question

I'm trying to follow section 3.4.2, starting on page 31 of this manual. However, as I have configured my target to be DIABLO_ARMEL rather than DIABLO_X86, I have gotten different results for this command:

[sbox-DIABLO_X86: ~] > gcc -Wall -g gtk_helloworld-1.c \
 ‘pkg-config --cflags gtk+-2.0‘ -o gtk_helloworld-1 \
 ‘pkg-config --libs gtk+-2.0‘
[sbox-DIABLO_X86: ~] >

I have checked the cflags and libs results of the commands in single quotes before entering this line, and the results between what were described in the example and what I saw in the command window.

Anyhow, I'm not expected to have error messages popping up in the terminal, but I got the following:

[sbox-DIABLO_ARMEL: ~] > gcc -Wall -g gtk-helloworld-1.c \
> 'pkg-config --cflags gtk+-2.0' -o gtk_helloworld-1 \
> 'pkg-config --libs gtk+-2.0'

I'm not sure what I'm doing wrong in terms of the include and library path configurations. It would be great if someone can provide some tips on fixing this error. Thanks in advance.

You need back-quotes around pkg-config:

gcc -Wall -g gtk-helloworld-1.c `pkg-config --cflags gtk+-2.0`... -o gtk ...
