| + | ====== | ||
| + | First install eldk described [[IceCube# | ||
| + | |||
| + | ===== Automake and Autoconf | ||
| + | We use automake and autoconf, because cmake cannot cross compile yet. | ||
| + | At first we need some files for automake: | ||
| + | < | ||
| + | touch NEWS | ||
| + | touch README | ||
| + | touch AUTHORS | ||
| + | touch ChangeLog | ||
| + | </ | ||
| + | |||
| + | Create a autogen.sh: | ||
| + | < | ||
| + | #!/bin/sh | ||
| + | rm -f config.cache | ||
| + | rm -f acconfig.h | ||
| + | |||
| + | autoreconf --force --install -I config -I m4 | ||
| + | #autoconf | ||
| + | #autoheader | ||
| + | #automake --add-missing | ||
| + | |||
| + | ./configure " | ||
| + | |||
| + | echo | ||
| + | echo "Now type ' | ||
| + | </ | ||
| + | |||
| + | We have the following directory structure: | ||
| + | < | ||
| + | / | ||
| + | -> i2c | ||
| + | </ | ||
| + | |||
| + | Now create a file called configure.ac: | ||
| + | < | ||
| + | AC_INIT(icecube, | ||
| + | AC_PREREQ(2.5) | ||
| + | AC_CONFIG_SRCDIR([i2c/ | ||
| + | AC_CONFIG_AUX_DIR(config) | ||
| + | |||
| + | AM_INIT_AUTOMAKE(1.8) | ||
| + | |||
| + | AC_PROG_CC | ||
| + | |||
| + | dnl Checks for header files. | ||
| + | AC_CONFIG_HEADER(config.h) | ||
| + | AC_HEADER_STDC | ||
| + | AC_CONFIG_FILES([Makefile i2c/ | ||
| + | AC_OUTPUT | ||
| + | </ | ||
| + | |||
| + | And a file Makefile.am: | ||
| + | < | ||
| + | EXTRA_DIST = autogen.sh configure | ||
| + | SUBDIRS = i2c | ||
| + | </ | ||
| + | |||
| + | In the directory i2c create a file Makefile.am: | ||
| + | < | ||
| + | INCLUDES = -I/ | ||
| + | |||
| + | bin_PROGRAMS = readMax6633 | ||
| + | readMax6633_SOURCES = readMax6633.c | ||
| + | </ | ||
| + | |||
| + | Now execute the script autogen.sh with: | ||
| + | < | ||
| + | ./ | ||
| + | </ | ||
| + | |||
| + | To cross-compile now do the following: | ||
| + | < | ||
| + | export CROSS_COMPILE=ppc_6xx- | ||
| + | make | ||
| + | </ | ||
| + | |||
| + | ===== cmake ===== | ||
| + | Create a file CMakeLists.txt: | ||
| + | < | ||
| + | project (ICECUBE) | ||
| + | |||
| + | SET(CMAKE_C_FLAGS " | ||
| + | add_subdirectory(i2c) | ||
| + | </ | ||
| + | |||
| + | And a file i2c/ | ||
| + | < | ||
| + | add_executable (readMax6633 readMax6633.c) | ||
| + | </ | ||
| + | |||
| + | Now execute: | ||
| + | < | ||
| + | CC=ppc_6xx-gcc cmake . | ||
| + | </ | ||
