I'm working on W98 and I'm trying to install the ARM development tools for Ecos (with Cygwin).  Im following the instruction on the internet page "Building the ARM development tools for Wondows" (sources.redhat.com/ecos/tools/win-arm-elf.html).  So, I configure the GNU Binary Utilities (binutils-2.10.1.tar.bz2) with the following cmds:     mkdir -p /tmp/build/binutils     cd /tmp/build/binutils     /src/binutils/binutils-2.10.1/configure --target=arm-elf \       --prefix=/tools \       --exec-prefix=/tools/H-i686-pc-cygwin \       -v 2>&1 | tee configure.out  -> OK And I Build and install the GNU Binary Utilities: make -w all install 2>&1 | tee make.out -> OK Then I configure GCC (gcc-core-2.95.2.tar.bz2 & gcc-g++-2.95.2.tar.bz2):   PATH=/tools/H-i686-pc-cygwin/bin:$PATH ; export PATH     mkdir -p /tmp/build/gcc     cd /tmp/build/gcc     /src/gcc/gcc-2.95.2/configure --target=arm-elf \       --prefix=/tools \       --exec-prefix=/tools/H-i686-pc-cygwin \       --with-gnu-as --with-gnu-ld --with-newlib \       -v 2>&1 | tee configure.out -> OK And I Build and install GCC: make -w all-gcc install-gcc \ LANGUAGES="c c++" 2>&1 | tee make.out -> OK   Then I configure the Insight GDB (insight-5.0.tar.bz2):     mkdir -p /tmp/build/gdb     cd /tmp/build/gdb     /src/gcc/insight-5.0/configure --target=arm-elf \       --prefix=/tools \       --exec-prefix=/tools/H-i686-pc-cygwin \       -v 2>&1 | tee configure.out -> OK And I Build and install GDB: make -w all install CC='gcc -mwin32' 2>&1 | tee make.out   -> OK     But when I want to use the Insight GDB, I have a big Windows Error (see attach : error arm-elf-gdb.gif).   -> NOK !!!!   I don't know what I must to do. I have already check the version of the tcl (version 8.0). This is the good version. So if somebody can help me!!! I will apreciate.   Stephane.    Attachment: error arm-elf-gdb.gif Description: GIF image
