[R] Error 127 and dlltool

[tom richards]

Hello:


My apologies for an earlier post on this topic for which I got one of
those stupid yahoo accounts, our email server having been down for two
days now...

Many thanks to Professor Ripley for responding to my 
earlier post, included below, about trying to use mingw32 gcc.
 
I cannot make libR.a under Windows NT.
 
Here is what I did, basd on readme.packages:
 
 1.)  Ensured that C:\Rtools was first in my path, and 
 obtained a new tools.zip from BDR's R tools site.
 
 2.)  Ensured that I do have Mingw-1.1, whose bin directory is 
 in my path.  Here is my path:
 
 C:\rw1051\src\gnuwin32>path
 PATH="C:\Rtools\";C:\Perl\bin;"C:\Mingw-1.1\bin";"C:\Rw1051\bi
 n";C:\WINNT\system
 32;C:\WINNT;"D:\Program 
 Files\Hummingbird\Connectivity\7.00\Accessories\";C:\Min
 gw-1.1\bin;
 
 3.)  Installed ActivePerl 5.6.1.
 
 4.)  Set R_HOME to C:\Rw1051
 
 5.)  edited MkRules:  set only HEADER=C:\mingw-1.1\include
 
 6.)  Tried to make make libR.a:
 
 C:\rw1051\src\gnuwin32>make libR.a
 
 dlltool -k --as as   --dllname R.dll --def R.exp --output-lib libR.a
 make: dlltool: Command not found
 make: *** [libR.a] Error 127
 Now, dlltool.exe is in mingw-1.1\bin, which is in my path.  I 
 have no idea why that file is not found!
 
 I tried a google search and found some earlier reports of 
 Error 127 and dlltool problems with R, but most seem to 
 involve using rcmd INSTALL.
 
 What is my next step here?  Have i missed something obvious 
 in readme.packages?  Thanks in advance...
