Hello, I've just almost managed to get scipy 0.3.2 compiled, up and running on HP-UX B.11.00 and here are some issues I had to deal with : 1) There should be some way to choose the fortran 77 compilers instead of manually editing the .py files, but maybe there is an environment flag I'm not aware of ? 2) ./Lib/xplt/src/play/unix/fpuset.c had to be modified in order to have it compiled correctly on HP-UX : **************************************************************** #elif defined(FPU_HPUX) /* man pages: fpsetmask * library: -lm */ /* HPUX turns off FP_X_* without this (_INCLUDE_HPUX_SOURCE) */ #ifndef _HPUX_SOURCE #define _HPUX_SOURCE 1 #endif #include <math.h> void u_fpu_setup(void) { fpsetmask(FP_X_INV | FP_X_DZ | FP_X_OFL); /* 0x1c */ fpsetfastmode(1); /* fast underflows */ } **************************************************************** has to be replaced by **************************************************************** #elif defined(FPU_HPUX) /* man pages: fpsetmask * library: -lm */ /* HPUX turns off FP_X_* without this (_INCLUDE_HPUX_SOURCE) */ #ifndef _HPUX_SOURCE #define _HPUX_SOURCE 1 #endif #include <fenv.h> void u_fpu_setup(int when) { if (when <= 0) { fesettrapenable(FE_INVALID | FE_DIVBYZERO | FE_OVERFLOW); } } **************************************************************** 3) In addtion to 2), you have to add math library '-lm' in order to compile fpuset.c. I solved it by editing ./Lib/xplt/config_pygist.py and replace the line 297: elif self.try_link("#define FPU_HPUX\n"+testcode, by elif self.try_link("#define FPU_HPUX\n"+testcode,libraries=[self.mathlib], 4) I had a "Bus Error (core dumped)" when calling the gamma.c function in ./Lib/special/cephes/gamma.c during the test scipy.test(level=1) It seems that the global variable P and Q are incorrectly defined, so I decided to use decimal configuration and add at the top of the file : #undef MIEEE #define UNK It seems to take care of the problem and I had no more errors when calling scipy.test(level=1) 5) When calling : python import scipy scipy.test(level=1, verbosity=2) The computer gets locked, it seems to get stuck in an infinite loop. I have to manually kill the python process But If I type : python -v import scipy scipy.test(level=1, verbosity=2) thus having displayed all the imported modules, everything goes fine ! All tests gets tested and are ok... Don't know if it's a python problem or a scipy problem though... 6) Can you add to the INSTALL.txt file that in order to get scipy find the fftw and ATLAS libraries you have to use an environment var locating both the libraries AND the headers ? I spent more than an hour before understanding that I have to use export ATLAS=/usr/local/lib/atlas:/usr/local/include/atlas instead of just export ATLAS=/usr/local/lib/atlas Hope that all this will help others and this great piece of software !
