cross compile tools

I need to run strace & gdb on the target arm device to toubleshoot. But there's no binary in the rootfs already. I decided to build it myself.

The toolchain I utilized is code source lit edition, here is the commands to issue:

1. strace

# apt-get source strace

# cd strace-4.5.20/

# CC=arm-none-linux-gnueabi-gcc ./configure --host=arm-none-linux-gnueabi    // ignore the warning message that suggest you set --build flag

# CC=arm-none-linux-gnueabi-gcc make

If you want to build strace statically, add  -static to AM_CFLAGS in Makefile before make, e.g.

AM_CFLAGS = $(WARNFLAGS) -static

Ok. Till now there will be a binary in you current dir.

you can strace it before you copy it to the target filesystem.

# arm-none-linux-gnueabi-strip strace

2. gdb

a) Modify gdb/gdb_curses.h to #include specifically.

b) Modify gdb/Makefile add "-I/workspace/DM365Core/products/common/dvsdk_3_10_00_19/linuxlibs-2009.11-armv5te/include/" to COMPILE

c) Add "extern int tgetnum (const char *);" to ./gdb/utils.c

commands:

# CC=arm-none-linux-gnueabi-gcc ./configure --host=arm-none-linux-gnueabi

# CC=arm-none-linux-gnueabi-gcc make

3. procps

a) Modify Makefile to add '-I/workspace/DM36x_IPCAM/products/common/dvsdk_3_10_00_19/linuxlibs-2009.11-armv5te/include' to CFLAGS

b) make CC=arm-none-linux-gnueabi-gcc

or alternatively: make SHARED=0 CC=arm-none-linux-gnueabi-gcc

to staticly link libproc to reduce binary size and save flash space.

4. binutils

# apt-get source binutils

# cd binutils-2.20.51.20100908/

# CC=arm-none-linux-gnueabi-gcc ./configure --host=arm-none-linux-gnueabi

# CC=arm-none-linux-gnueabi-gcc make

Enjoy yourself!
