I think this is not a R-devel question. Sorry to all if I'm wrong, please let me know.
I managed to build R successfully with the default BLAS but when I change the MKRULES to use ATLAS BLAS and set the path to "C:/cygwin/home/Administrador/ATLAS/lib/WinNT_ATHLONSSE2" I got the following error message (I'm posting only the final part, there was a lot of compilation before this): cp R.dll ../../bin/ -------- Building ../../bin/Rblas.dll -------- gcc -shared -s -o ../../bin/Rblas.dll blas00.o dllversion.o Rblas.def \ -L../../bin -lR -L"C:/WinNT_ATHLONSSE2" -lf77blas -latlas C:/WinNT_ATHLONSSE2/libf77blas.a(xerbla.o):xerbla.f:(.text+0xb): undefined refer ence to `s_wsfe' C:/WinNT_ATHLONSSE2/libf77blas.a(xerbla.o):xerbla.f:(.text+0x27): undefined refe rence to `do_fio' C:/WinNT_ATHLONSSE2/libf77blas.a(xerbla.o):xerbla.f:(.text+0x43): undefined refe rence to `do_fio' C:/WinNT_ATHLONSSE2/libf77blas.a(xerbla.o):xerbla.f:(.text+0x48): undefined refe rence to `e_wsfe' C:/WinNT_ATHLONSSE2/libf77blas.a(xerbla.o):xerbla.f:(.text+0x5c): undefined refe rence to `s_stop' collect2: ld returned 1 exit status make[2]: *** [../../bin/Rblas.dll] Error 1 make[1]: *** [rbuild] Error 2 make: *** [all] Error 2 The ATLAS BLAS was build using Cygwin. AFTER building ATLAS BLAS I changed the "Path" variable putting "C:\Rtools\tools\bin;C:\MinGW\bin" before everything else. To build R I followed "R Administration and Instalation" and Duncan Murdoch's guide at http://www.murdoch-sutherland.com/Rtools/, including the version of MinGW. At ATLAS web page (http://math-atlas.sourceforge.net/errata.html) I found the following: Q: I'm linking with C, and getting missing symbols (such as w_wsfe, do_fio, w_esfe or s_stop). R: These kinds of symbols are Fortran library calls. The problem is that the C linker does not automatically find the Fortran libraries. The most common fix is to either link using your fortran linker, or to rewrite your code so that Fortran routines are not called. If you know where they are, you can also choose to link in the Fortran libraries explicitly Well, I can understand that there is a huge probability that this is my problem. Unfortunately I know nothing of C or Fortran. Even if I knew that I have these Fortran libraries I wouldn't know how to link them. I tried to look at MinGW web page but found nothing. Any help would be mostly welcome, please. Giuseppe Antonaci Sorry for English errors and lack of knowledge. I hope I made myself understandable. ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
