[ECOS] Trying to build sample apps

[ECOS] Trying to build sample apps

[Michael Trozzo]

Hello,

I've been able to get the tests running correctly, and I am now trying
to take the next step and build the sample applications in the user
guide.  I'm quite confused about the correct paths to compile/build the
files.  I've been going back and forth especially between chapters 11
and 13, and I can't quite figure what I'm doing wrong.  The output from
my cygwin window is below. Any help would be appreciated!

>> I'm quite confused

You try to invoke the program "i386-elf-gcc", but it does not seem to be in your
search path. To check this, type
"echo $PATH". If you want to invoke "i386-elf-gcc" you have the following
options:
a) include the "/opt/ecos/gnutools/i386-elf/bin" folder in your search path
b) use a symbolic link to "i386-elf-gcc" and place that link in a folder which
is included in your search path
c) invoke the program directly by using an absolute path:
"/opt/ecos/gnutools/i386-elf/bin/i386-elf-gcc" or "cd
/opt/ecos/gnutools/i386-elf/bin" and "./i386-elf-gcc" (notice the ./ )

If you build i386-elf-gcc yourself, didn't you forget to do a "make install"?
