GDB cross compiler

objective

• compile gdb static for mips /el

pre

• create build and source folders
• download gdb 7.9 and termcap 1.3.1 to source folder
• create cross compiler with buildroot or crosstool-ng (i used buildroot)

termcap

under build folder create sub folder 

(host)$mkdir -p build/termcap/mipsel

(host)$export CC=<path>/buildroot/output/mipsel/host/usr/bin/mipsel-linux-gcc

(host)$./configure --host=mipsel-linux --prefix='/<path>/build/termcap/mipsel/'

(host)$make

(host)$make install

gdb 7.9

(host)set PATH=/to/gcc/folder

(host)$cd to gdb-7.9 folder #don't run process from gdb subfolder see README

(host)$export CC=<path>/buildroot/output/mipsel/host/usr/bin/mipsel-linux-gcc

#set ld flags: static and point to termcap lib folder

(host)$export LDFLAGS="-static -L/<path>/build/termcap/mipsel/lib"

#set include to termcap include folder

(host)$export CFLAGS="-g -O2 -I/<path>/build/termcap/mipsel/include"

(host)$./configure --host=mipsel-linux --prefix='/<path>/build/gdb_mipsel' --disable-werror

(host)$make

(host)$make install

Note

host: compiler prefix
