[ECOS] eCos installation instructions

[ECOS] eCos installation instructions

[Michael W. Ellis]

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It looks like the Cygwin gcc4 and libmpc1 packages have been withdrawn.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?
