similar to: [LLVMdev] IsNAN.cpp:23:3: #error "Don't know how to get isnan()"

Hi Brian Here's the config.log (I'm not posting it on the dev-list). The automatic gcc macro for Interix is __INTERIX if this is to any help. /Henrik >From: "Brian R.

Hi Brian, I've been playing around with your test programs and came to the result: --------------------- #ifdef __INTERIX # define _GLIBCPP_USE_C99 1 //Define this macro before including isnan() function from cmath #endif #include <cmath> using std::isnan; int foo(float f) {return isnan(f);} --------------------- /Henrik >From: "Brian R.

I don't know if Paolo submitted his patches for these files, but they are not in the CVS -- I've chosen a slightly different strategy, adding a case that checks if the compiler is MSVC instead of adding HAVE_FINITE_IN_FLOAT_H and HAVE_ISNAN_IN_FLOAT_H to the config.h file. I don't know which is the best approach, but this is the minimal patch to make it work... m. --------------

I submitted a patch keeping the traditional approach, HAVE_FINITE_IN_FLOAT_H and HAVE_ISNAN_IN_FLOAT... Just another case added to the others instead of a custom approach. --- Paolo On Oct 19, 2004, at 12:16 PM, Morten Ofstad wrote: > I don't know if Paolo submitted his patches for these files, but they > are not in the CVS -- I've chosen a slightly different strategy, >

By the way, somebody (I think it was Chuck, but I don't remember for certain) was asking for the BuildLog.htm from building the llvm.sln file under VS 2005 SP1 for diagnostic purposes; right now the SLN is configured to produce a new BuildLog for each and every one of the projects inside the solution. I don't know who's responsible for this guy, but that's probably not the best way

In the hope of some meaningful response and ignoring the risk of further abuse, let me try to clarify the issue here. I have re-read the 'Writing R Extensions' manual. It seems to me that it clearly says R API functions can be called from from C++ programs, and the API includes the special values ISNAN() and R_FINITE() and the missing test ISNA(). R_FINITE is no problem. It is

Hi Guys I'm trying to port and build LLVM to the Interix environment. I've succeded until the Interix version of gcc program executes: gmake[1]: Entering directory `/usr/local/src/llvm/lib/Support' gmake[1]: Leaving directory `/usr/local/src/llvm/lib/Support' gmake[1]: Entering directory `/usr/local/src/llvm/lib/Support' Compiling CommandLine.cpp CommandLine.cpp: In function

I have a problem building an extension using ISNAN() on R version 2.0.x. In R 1.9.1 Arith.h and Rmath.h contained code like #ifdef IEEE_754 # define ISNAN(x) (isnan(x)!=0) #else # define ISNAN(x) R_IsNaNorNA(x) #endif #define R_FINITE(x) R_finite(x) int R_IsNaNorNA(double); int R_finite(double); which works. R 2.0.x has # define ISNAN(x) (isnan(x)!=0) unconditionally. This breaks

Dear R users, Have you experienced any difficulty in calling R's ISNAN() from a C code? I have C codes including ISNAN() calls and they worked well until I upgraded my R from 1.7 to later versions. When I tried to compile the codes in the version 1.8 and 1.9, I got error messages like this: test.obj : error LNK2001: unresolved external symbol _isnan .\testR.dll : fatal error LNK1120: 1

Hi again Does cygwin support shared libraries.

Hello, I submitted a package which used Fortran functions isnan and lgamma. However, I was told that: isnan and lgamma are not Fortran 95 functions. I was asked to write 'cross-platform portable code' and so should not be writing GNU extensions to Fortran. See http://cran.r-project.org/web/checks/check_results_mpath.html, which will shortly show installation failures under Solaris. I
