Hi all,
I made a C application that uses threads but each time I try to build it the
following error resides after make

make: *** [all] Error 1
However my make file as following :-
CC = /root/omap_pm/usr/local/
angstrom/arm/arm-angstrom-linux-gnueabi/bin/gcc
all:
$(CC) -g -Wall Hello_threading.c -o Hello_threading
-Wl,-rpath-link=/root/rowboat-android/out/target/product/beagleboard/obj/lib/,-dynamic-linker=/system/bin/linker
-L/root/rowboat-android/out/target/product/beagleboard/obj/lib/ -nostdlib
/root/rowboat-android/out/target/product/beagleboard/obj/lib/crtbegin_dynamic.o
-lc
Any Idea !!!!!!!!!!!!!!!!!!!!
I dunno why does the linker searches in it's library not the library
specified by me after the -L option!!!????
