cannot convert int* to integer*

[yifli82]

Hi all,

I downloaded clapack from http://www.netlib.org/clapack/ and compiled it successfully.

However, I got the following error when calling dsyev_:

error C2664: 'dsyev_' : cannot convert parameter 3 from 'int *' to 'integer *'

How should I resolve this error? Thanks

You need to make sure you #include <f2c.h> in your source file. In the f2c.h header file, there is a typedef that sets the "integer" type.

Hi Rodney,

I did include f2c.h. However, in f2c.h

Code: Select all

typedef long int integer;

I fixed the problem by declaring the relevant variables as 'long int' instead of 'int'.

Thanks

You could also, if you wanted to use int's instead of long int's, change the typedef in f2c.h to "typedef int integer" and recompile everything...
