I am attempting to install the eCos development tools on a Win7 64-bit machine and have quickly encountered problems attempting to follow the installation instructions. I come from a hardware background but have written quite a bit of embedded software, but I'm not familiar with eCos, Cygwin, Eclipse and all the related tools, so consider me a total newbie with regards to eCos.
I am attempting to follow the instructions at http://ecos.sourceware.org/getstart.html and the first step is to install Cygwin. Following the instructions on http://ecos.sourceware.org/cygwin.html I have downloaded and launched the 32-bit version of the Cygwin installer. The instructions then say to install the following packages:
gcc4 - see below
libexpat1 - found under Libs
libmpc1 - see below
make - found under Devel
patch - found under Devel
sharutils - found in Archive
tcl - found under Interpreters
wget - found under Web
Searching for gcc4 yields no results. Searching for gcc vields many results (cygwin64-gcc-*, gcc-*, mingw64-i686-gcc*, mingw64-x86_64-gcc-*) under the Devel category, and libgcc1 under the Libs category. What is the appropriate choice for gcc4? I assume that these are different toolchain options but I have no idea whether eCos requires a particular choice.
The library libmcp1 was not found. Searching for libmpc yielded libmpc3 - am I to assume that this is an appropriate substitution?
Thanks,
Michael

It looks like the Cygwin gcc4 and libmpc1 packages have been withdrawn.
I suggest you try the gcc-core and libmpc3 packages instead. You may
need to create /bin/cygmpc-1.dll as a symbolic link to /bin/cygmpc-3.dll
in order to satisfy the dependencies of the eCos toolchains. Does this
work for you?
