MinGW and the ld bug

Henrik Bengtsson-2
Hi.

I noticed that Brian Ripley found and corrected a bug in MinGW's
ld.exe, see http://www.murdoch-sutherland.com/Rtools/.  Thanks for
this.  I wonder if this is the same bug that cause my problems.  I
have tiny toy package with C code that installs perfectly on R Version
2.2.1 beta (2005-12-18 r36792) [this version was mislabelled "beta"
the first few hours on CRAN when the stable 2.2.1 version first came
out].  However, when I try to install the same on R Version 2.2.1
Patched (2006-02-09 r37305) as well as R Version 2.3.0 Under
development (unstable) (2006-02-02 r37243), I get the following error:

C:\Documents and Settings\hb\braju.com.R\R.native\build>Rcmd install R.native

---------- Making package R.native ------------

Removing 'C:/PROGRA~1/R/R-2.2.1pat/library/R.native'
Restoring previous 'C:/PROGRA~1/R/R-2.2.1pat/library/R.native'

My R.native.def looks like this:

LIBRARY R.native.dll
EXPORTS
 rowMedians
 rowMediansInteger
 rowMediansReal

I've tried to replace the two occurances of ld.exe in MINGW with BR's
patch, but I get the same error.  The ld of the patch and the original
one show the same version string;
patch: GNU ld version 2.16.91 20050827 and original: GNU ld version
2.16.91 20050827. I've tried to use both MINGW v5.0.0 and v5.0.2 with
both "current" (v3.4.2) and "candidate" (v3.4.4) packages.

Is this related to the bug BR found?  Any suggestions what might go
wrong between R v2.2.1 and v2.2.1 patched?

Thanks

Henrik

Re: MinGW and the ld bug

Brian Ripley
I believe the bug is triggered by the fairly unusual event you have a '.'
in the package name, and the change in 2.2.1 to 2.2.1 patched was to add

> LIBRARY R.native.dll
                   ^^^^
(which is what my workaround in ld.exe was doing another way).

Since we are told that is the correct form and we were using it
incorrectly before, I don't really know how to work around this.  For you,
just delete .dll in the following line in src/gnuwin32/MkRules

%.dll:
  @$(ECHO) LIBRARY $*.dll > $*.def

but that is not a general solution.

Hmm, only 3.4.5 is there as a candidate.

Thanks. With "@$(ECHO) LIBRARY $ > $*.def" it works again.

All the best,

Henrik
