#1459: Build fails with "lexical error at character '\a'"
-------------------------------------------+--------------------------------
Reporter: [EMAIL PROTECTED] | Owner:
Type: bug | Status: new
Priority: normal | Milestone:
Component: Build System | Version: 6.6.1
Severity: normal | Keywords:
Difficulty: Unknown | Os: Linux
Testcase: | Architecture: x86
-------------------------------------------+--------------------------------
There are a couple of Makefiles that contain something like:
echo "main = getArgs >>= \args -> ..."
On my system, I get an error building the HEAD (checked out today) with:
ghc-pkg-inplace.hs:2:19: lexical error at character '\a'
It seems like something weird happens with the backslash getting escaped
or not escaped, and the generated file, ghc-pkg-inplace.hs in this case,
ends up with the character '\a' in it (^G). If I change "\args" to
"\\\\args" in the Makefile, I get the right result.
I'm submitting a bug rather than fixing it since I assume that on *some*
system this worked correctly, so maybe my fix would break it on some other
system.
I'm not sure what about my environment might be relevant, besides:
$ uname -a
Linux bongo 2.6.17-10-generic #2 SMP Tue Dec 5 22:28:26 UTC 2006 i686

$ make --version
GNU Make 3.81
$ echo $SHELL
/bin/bash
$ bash --version
