Error 127 and dlltool
Hello: Many thanks to Professor Ripley for responding to my earlier post, included below, about trying to use mingw32 gcc.I did put back the original Rinternals.h. I am still crashing R every time I try to use C code. 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\bin";C:\WINNT\system32;C:\WINNT;"D:\Program Files\Hummingbird\Connectivity\7.00\Accessories\";C:\Mingw-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... Tom Richards

Hello:
I have not compiled C code for R since around version
1.1.0, and i see that
I am really missing something here. I am using widoes and
mingw32 port of
gcc. Now, as usual I have gone into Rinternals.h and
physically changed all
declarations of functions returning SEXP's to
__declspec(dllimport) SEXP
but I still am getting repeated crashes of R. Do any
windows users know
what I am forgetting to do here? Thanks in advance.
Not leaving things alone? There is no need to change the
header files if
you follow exactly the documented procedures.
