| You miss the comma. This is a gcc option, not a libtool option. Xcode calls gcc to link the binary, and gcc call ld. If you want to pass an option to ld, you have to use "-Wl,<your option>"
man gcc -> Linker Options

Yes, I did a typo in my first reply, but jonas posted a fixed:

/Developer/usr/bin/libtool unknown option character 'W' in -W -pie.
Command /Developer/usr/bin/libtool failed.

Hi All,
I was following the steps for getting the ASLR (Address Space Layout Randomization) settings for my Application.
But when I set Project/Target Settings > Build > Other Linker Flags > as "-pie" I get errors as /Developer/usr/bin/libtool: can't open file: lpie (No such file or directory).
Try '-W-pie' instead of '-pie'
The -W option tell gcc to pass the following string (-pie here) to ld when linking.
But for other two settings "-fpie" in "Other C Flags" setting and "Generate Position-Dependent Code" as off.
Is something silly I am doing.
Thanks,
