[MacPorts] #50311: gmt5: build fails on Mavericks: error: conflicting types for 'dsyev_'

[Takeshi Enomoto]

Hi,

I’m trying to fix the problem reported for gmt5.

gmt5 fails due to the incompatibility of pointer type
on a call to dsyev_ of CLPACK in Accelerate.

The reporter runs Mavericks on an i386 machine
(I didn’t know that i386 is supported).

According to the error message in main.log, int * is passed to long *.

incompatible pointer types passing 'int *' to parameter of type '__CLPK_integer *' (aka 'long *’)

It should be int * because it is 4-byte integer of Fortran.

I suspect the compiler doesn’t compile the source with __LP64__ symbol on i386.
Perhaps is this a problem of Xcode clang?
Would put this clang version to blacklist help?

Comments and help welcome.

Regards,

Takeshi

Excerpt from /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/Headers/clapack.h:

 #if defined(__LP64__) /* In LP64 match sizes with the 32 bit ABI */
     typedef int     __CLPK_integer;
 #else
     typedef long int  __CLPK_integer;
 #endif
