#3004: Makefile needs to improve treatment of HsColour
-----------------------------+----------------------------------------------
Reporter: nr | Owner:
Type: bug | Status: new
Priority: normal | Component: Build System
Version: 6.11 | Severity: minor
Keywords: | Testcase:
Os: Unknown/Multiple | Architecture: Unknown/Multiple
-----------------------------+----------------------------------------------
Fresh checkout, a few new patches, sh boot & configure are OK, but 'make'
results in
{{{
: n...@labrador 10435 ; make
HsColour needed but wasn't found.
Set HSCOLOUR_SRCS=NO if you don't want to use it
exit 1
make: *** [check-tools] Error 1
}}}
Things that are wrong here:
1. 'sh boot; ./configure; make' failed. This should never happen.
1. I'm not told ''where'' to set {{{HSCOLOUR_SRCS=NO}}}.
1. The missing software should be detected by ./configure and the
variable set then.
1. The error message (which should be a warning message from configure)
does not tell me how to get and install the HsColour software. The error
message should include information along the following lines:
{{{
If you do want to use the software, the source is at
http://hackage.haskell.org/cgi-bin/hackage-scripts/package/hscolour
If you've got cabal-install then:
$ cabal update
$ cabal install hscolour
}}}
5. Finally, the message should say what {{{HsColour}}} is so that the
rank amateur (me) can figure out if it's worth installing.
