Howdy All!
I have found out that when I compile java code in cygwin, I have to make
sure that my classpath and file names are in DOS format. For example;
CLASSPATH=".;C:\temp" javac "C:\temp\AuctionEntryImpl.java"
I believe this is required because the javac that is being used is a
DOS/Windows javac and the file paths are translated.
True.
My problem is that I am trying to install the Janos nodeos which has a
large set of build scripts that require Linux like paths, not DOS. My
reason for saying this is because I am getting error messages like this:
error: cannot read:
/cygdrive/c/java/jnodeos-20020317/src/nodeos/Address.Java
I take this to mean that the script is building Linux paths which are not
understood by the DOS javac.
True.
If I have assumed correctly so far, can I download a Linux/Unix javac and
will it use the Linux paths ok?
You say "download". Yes, of cause you can download a Linux/Unix Javac -
just don't expect it to actually WORK on Windows. Remember, Cygwin is just
a layer on top of Windows. You cannot run Linux binaries on Windows by
using Cygwin.
I have examined some of the build scripts - it is not easy to change how
they deal with paths because they do a lot sed operations (for example)
and heaps of variable substitutions as part of their sanity checks.
I would have guessed, without looking at all, that there are very few
invocations of Javac. Leave the sed/variable substitution alone and look at
patching the actual invocation of Javac with `cygpath -w "$directory"` and
`cygpath -w -p "$CLASSPATH"`.
Good luck.
