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
