    Linking problem...

    Just to make sure I'm not looking at the screen cross-eyed, here's the thing

    $ nm libqhull.a | grep MY_qh_init_B
    00000b1c T MY_qh_init_B

    -----------------------------

    $ hcustom -L . -lqhull -lm SOP_Qhull.C
    Linking with 'libqhull'
    Linking with 'libm'
    Making SOP_Qhull.o and /home/briank/houdini5.5/dso/SOP_Qhull.so from SOP_Qhull.C
    SOP_Qhull.C: In method `OP_ERROR SOP_Qhull::cookMySop (OP_Context &)':
    SOP_Qhull.C:546: `MY_qh_init_B' undeclared (first use this function)
    SOP_Qhull.C:546: (Each undeclared identifier is reported only once for
    each function it appears in.)
    Compile failed

    FYI: "hcustom" is a kind of makefile. Shouldn't the fact that "MY_qh_init_B" is defined in libqhull.a mean that I shouldn't be getting the undeclared error during compile for "SOP_Qhull.h"?

    Did you forget to include "SOP_Qhull.h" in "SOP_Qhull.C"?
    Code:
    int main(void){srand(time(0));for(double l=rand(),l0=0,l00=0;;l0+=0.1){for(double l000=0;l000
<1;l000+=.001,l+=((double)rand()/RAND_MAX)/0x64,l00+=((sin(l*0x8*atan(l0)*l000-(l0*0x8*atan
(l)))*0.5)+0.5)){l00-=floor(l00);for(size_t l0000=0,l00000=(size_t)(0x50*(l00));l0000<l00000;++l0000
)putchar(0x20);putchar(0x61+(int)((double)rand()/RAND_MAX*0x1a));putchar('\n');}}return 0;}

    Sebastiani: yup - double checked SOP_Qhull.h is included

    Salem: good idea (and one I hadn't thought of) - unfortunately, it didn't change anything.

    ... back to the drawing board - any other ideas? other things to look at? If it would really help to show hcustom, I can pull out the appropriate parts - just say the word.
