The Makefile target attempts to create a simple file containing:
print "Hello World\n"
end
Alas, it's hard to create that file portably. In particular,
echo 'print "Hello World\n"'
gives different results with different 'echo' commands. The
default bash behavior is to pass the \n on through. The default
ksh behavior is to interpolate the \n and replace it by an actual
newline. Adding the -e flag to bash's echo command forces it to
act like ksh, but ksh complains about the unrecognized -e option.
The symptom of this is the following rather mysterious error message:
error:imcc:op not found 'print' (print<0>)
in file 'hello.pasm' line 1
We could use a perl one-liner in place of echo, but getting all the quotes
right across different operating systems is still hard.
This patch takes a simpler approach: it creates a new file
examples/assembly/hello.pasm, and just uses that.
It still doesn't work on Solaris/SPARC. I now get
error:imcc:main: can't produce object file*** Error code 1
but that's to be expected because the code simply isn't written yet to
produce native executables on this platform.
