#7639 closed bug (fixed)

Fix installation issues with cross compiling + honour Stage1Only properly

This patch fixes three problems that occur during a cross compile to embedded Linux (details below):

  1. arm-ldu-linux-gnueabi-ghc-pkg gets a symlink but no wrapper script upon installation, and this causes the installation to break later when it tries to run it.
  1. hp2ps doesn't get the prefix like the other commands do (i.e. arm-ldu-linux-gnueabi-ghc- is missing from the name of the executable). This is just for consistency.
  1. The stage2 compiler is built when Stage1Only is set to YES (though it does not get installed). This makes the build take longer than it needs to.



configure command:

./configure --target=arm-ldu-linux-gnueabi --prefix=/usr/local/ghc-ldu

In case it's helpful, with this patch I am suggesting in this ticket...

...if it isn't applied, then this is what I get (latest head, git hash ca5d15a61c45d6ea763872df46efe5c7b33f8186):

So, arm-ldu-linux-gnueabi-ghc-pkg is a dangling symlink.

If I then apply the patch, then the wrapper arm-ldu-linux-gnueabi-ghc-pkg-7.7.20130203 gets installed and the problem goes away.

Ok, a fix for the ghc-pkg issue is coming (I didn't understand the fix, so spent some time looking at it, and I think I've done it in a slightly cleaner way).

Regarding the stage 2 issue, strictly speaking building compiler/stage2 is correct, because it is the ghc package that can be used with the cross-compiler. If you don't want to build it, then setting stage = 1 in your mk/ should disable it.

Thanks. Will try out 'stage = 1' and add a note to the CrossCompiling wiki page if it does the trick.
