Listing threads: procps cross compile issue
Hi, I want to list the user space threads in ps output. The busybox ps command doesn't have the option to list the threads. So I am trying to cross compile procps and port ps onto the target board (OMAP L138 based eXp board with ARM core and Davinci code base). But it fails during compilation. Here is the command I run and few lines from the compile time errors.
procps-3.2.8# make CC=arm-none-linux-gnueabi-gcc CPPFLAGS= lib64=lib m64=
arm-none-linux-gnueabi-gcc -D_GNU_SOURCE -I proc -fno-common -ffast-math -W -Wall -Wshadow -Wcast-align -Wredundant-decls -Wbad-function-cast -Wcast-qual -Wwrite-strings -Waggregate-return -Wstrict-prototypes -Wmissing-prototypes -O2 -s -c -o top.o top.c

top.c:72: error: 'COLOR_BLUE' undeclared here (not in a function)
top.c:72: error: 'COLOR_GREEN' undeclared here (not in a function)
top.c:72: warning: missing initializer
top.c:72: warning: (near initialization for 'Rc.win')
top.c: In function 'tg2':
top.c:316: warning: implicit declaration of function 'tgoto'
top.c:316: error: 'cursor_address' undeclared (first use in this function)
top.c:316: error: (Each undeclared identifier is reported only once
top.c:316: error: for each function it appears in.)
top.c:316: warning: pointer/integer type mismatch in conditional expression
Here it fails while building top. so was I even trying to modify the Makefile to remove other binaries and keep only ps. But I am surprised I didn't see any reference to ps in the list of targets.
As expected I see the threads under /proc. Is an alternative to list threads in an embedded Linux environment?
