[SciPy-user] Compilation error of fblaswrap_veclib_c.c

[HEMMI, Shigeru]

Dear David Cournapeau,

Thanks for the reply.

For the code you suggest,

#include <complex.h>
int main()
{
    complex a = 1.0 * I;
    return 0;
}

it worked, but after replacing #include <complex.h> by #include
<vecLib/vecLib.h>, I encounterd an error.

$ gcc tmptesting.c
tmptesting.c: In function `main':
tmptesting.c:5: error: `complex' undeclared (first use in this function)
tmptesting.c:5: error: (Each undeclared identifier is reported only once
tmptesting.c:5: error: for each function it appears in.)
tmptesting.c:5: error: parse error before "a"

Is there any suggestions?
(I believe that gcc I am using is just the gcc that Apple supplied.
 However, I am not sure <vecLib/vecLib.h> is stil correct or not.
 I have been trying installing/uninstalling some other gccs
 many times and now I believe I am using Apple supplied gcc.)

Regards,
