Hi, in the plplot-general forum, a issue regarding the isnan() function on AIX was reported. So far we could solve the issue (see the attached message) in CBS, but I didn't commit anything and also some changes elsewhere in the plplot code (where isnan is used) might be necessary. Could somebody take over, since I'm away the next 7 days. If not I'll do that after next week.

--- Begin Message ---Read and respond to this message at: https://sourceforge.net/forum/message.php?msg_id=6301077 By: joachim_geiger Hi Werner, if I compile TestNaNAware.c in cmake/modules using xlc I get: "TestNaNAware.c", line 3.10: 1506-296 (S) #include file "nan.h" not found. "TestNaNAware.c", line 9.15: 1506-045 (S) Undeclared identifier NaN. With a little help I recognized that the definition for NaN is in math.h, but as NAN. The code now reads as: /* Test for NaN awareness. */ #include <stdio.h> #if defined(_AIX) #include <math.h> #elif #include "nan.h" #endif int main() { #if defined(_AIX) double x = NAN; #elif double x = NaN; #endif /* N.B. CMake run-time tests need return of true (1) or false (0) not * the usual status code of 0 for success. */ #if defined(_MSC_VER) | defined(__BORLANDC__) | defined(_AIX) if (isnan(x)) return 1; #endif if (x != x) return 1; else return 0; } Now it compiles with xlc, but when loading I get: ld: 0711-317 ERROR: Undefined symbol: ._isnan ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information. Finally also solved the loader problem by linking with libm.a . However, the check for isnan at the beginning is still there, since this is done with the cmake function check_function_exists which is called in plplot.cmake . I hope you can come up with a solution using my results.
