Daffodil claims to support building on Windows, with build instructions
in our README. I would suggest we not give up by switching to Linux, and
instead to try resolve this problem. It likely means part of our build
instructions are either incorrect or unclear. It would be valuable to
get this resolved.
Varun, I *think* you may need to run the commands in MSYS2, I don't
think we currently support powershell.
Based on the error you got in MSYS2, it sounds like you need to install
Java, we usually suggest downloading and installation OpenJDK following
the instructions here:

Subject: Initial Compilation Errors
Hello,
I have recently joined the effort to work on apache/daffodil. I am trying to
work an open issue; however, I am running into compilation errors on a clone of
apache/daffodil that I have made no changes to. I am working on a Windows
computer and the steps I have followed are listed below:
Steps:
1. Fork apache/daffodil
2. Clone the forked repository to local machine
3. Follow the instructions in the BUILD.md file (all steps below were done
in a MSYS2 window)
* Run "pacman -S clang diffutils gcc git make pkgconf"
-- Succeeded
* Run "export CC=clang AR=llvm-ar"
-- Succeeded
* Run "git clone -b v3.3 https://github.com/michaelrsweet/mxml.git
unset CC AR
cd mxml
./configure --prefix=/usr --disable-shared --disable-threads
make
make install
"
--Succeeded
* Run "export MSYS2_PATH_TYPE=inherit"
--Succeeded
Error(s):
1. Powershell/IDE Compiling
When I run "sbt compile" within an IDE that has the daffodil directory open,
the error I receive is:
"(daffodil-runtime2 / Compile / cCompile) java.io.IOException: Cannot run program
"cc": CreateProcess error=2, The system cannot find the file specified"
I had set my environment variable "CC" to "clang" and "AR" to "llvm-ar", however I receive the
same error as before but the "cc" is changed to "clang" in the error message.
I have downloaded LLVM-11.0.0-win64 in an attempt to have clang downloaded but I do not
think I have done this correctly since "clang" is not a recognized command in
Powershell.
1. MSYS2 Compiling
When I run "sbt compile" from the MSYS2 window, I receive a "sbt command not
found". As such, I had added sbt to the PATH variable and received these errors:
/c/Program Files (x86)/sbt/bin/sbt: line 453: java: command not found
copying runtime jar...
mkdir: cannot create directory '': No such file or directory
/c/Program Files (x86)/sbt/bin/sbt: line 460: java: command not found
/c/Program Files (x86)/sbt/bin/sbt: line 220: java: command not found
Has anyone ran into similar issues? I appreciate any help and apologize for any
novice mistakes I have made.
Thanks!
Best,
Varun
