But they may want to join the development of nnARM.  So I provide GNU Tools for ARM here.<br><br></b></font><p><font  color="000088"size=+1><b>2 GNU Tools Chain<br><br></b></font><font><b>binutils-2.10.91.0.2<br>gcc-2.96<br>gdb-5.0<br>newlib-1.9.0<br><br>I found these tools (except newlib-1.9.0) on the RedHat 7.1 source code CD, you can also download them from <a href="ftp://ftp.gnu.org/gnu/">ftp://ftp.gnu.org/gnu/</a><br>And newlib-1.9.0 can be downloaded from <a href="ftp://sourceware.cygnus.com/pub/newlib/">ftp://sourceware.cygnus.com/pub/newlib/</a><br></b></font><p><font  color="000088"size=+1><b>3 Configure and Build<br><br></b></font><font><b>It is very simple to configure and build, and I will describe the process below:<br><br>First, you must download all the tools packages, and place them in the same directory, assume /root/newgnu<br><br>Then unpack them with tar to the current directory, you will get four sub directories each containing source code of a package:<br>/root/newgnu/binutils-2.10.91.0.2<br>/root/newgnu/gcc-2.96-20000731<br>/root/newgnu/gdb-5.0<br>/root/newgnu/newlib-1.9.0<br><br>Because I want to build tools for various kinds of targets such as arm-elf and arm-aout, I use a new directory other than the source code directory to configure and build.  Use the following commands to create new directories:<br><br>mkdir /root/newgnu/build-bin<br>mkdir /root/newgnu/gcc<br>mkdir /root/newgnu/newlib<br>mkdir /root/newgnu/gdb<br><br>First, you must configure and Build binutils package<br>I have a script that does it automaticlly<br><br>../binutils-2.10.91.0.2/configure --target=arm-elf --prefix=/usr/local -v<br><br>you must run this script in /root/newgnu/build-bin, if there is no error, then just type the following command to build:<br><br>make all<br><br>if there still is no error, type in the following command to install<br><br>make install<br><br>Next, to configure and build gcc<br><br>change to the source code directory of gcc, and add a symbolic link to the content of newlib so that configure can find newlib<br><br>ln -s /root/newgnu/newlib-1.9.0/newlib newlib <br>ln -s /root/newgnu/newlib-1.9.0/libgloss libgloss <br><br>then you can start to configure gcc using the following command in /root/newgnu/build-gcc<br><br>../gcc-2.96-20000731/configure --host=i686-pc-linux --target=arm-elf --prefix=/usr/local -v--with-newlib<br><br>then use the following command to build and install gcc:<br><br>make all install<br><br>if no error, then continue to build newlib, goto /root/newgnu/build-newlib and run the following command:<br><br>../newlib-1.9.0/configure --host=i686-pc-linux --target=arm-elf --prefix=/usr/local -v <br><br>if no error then run the following command to build and install:<br><br>make all install<br><br>then run the following command to configure and build and install gdb:<br><br>CC=/usr/bin/gcc<br>../gdb-5.0/configure --host=i686-pc-linux --target=arm-elf --prefix=/usr/local -v<br>make all<br>make install<br><br>when I run make all, the compiler tells me that it "does not know the storage size of struct tm in file /root/newgnu/gdb-5.0/gdb/rdi-share/devsw.c in line 39 and 69"<br>to solve this problem, just comment out these two lines, because they just declare two variables that are never used<br>run the above commands again and all is OK<br><br></b></font><p><font  color="000088"size=+1><b>4 How to use GNU Tools<br><br></b></font><font><b>For gcc, just use "arm-elf-gcc" to replace "gcc" to compile your program<br><br>For gdb, just use following command:<br><br>arm-elf-gdb program -x gdb-cmds<br><br>gdb-cmds is a command file for arm-elf-gdb, its content is listed below:<br><br>target sim<br>load<br><br>then you can debug programs with your favorite commands<br>Of course, please make sure that /usr/local/bin is in your path<br></b></font><p><font  color="000088"size=+1><b>5 insight:GUI for gdb<br><br></b></font><font><b>insight is a GUI for gdb, when you download insight, you also get gdb in the same package.

In fact, Insight is GDB with a GUI, so the only difference is the path of the source code.
