Subject: [Lapack-users] lapacke-3.5.0 build failure with -m32 switch
Message-ID: <201503180915.58762.sibxol@btconnect.com>

Greetings,

I tried to build lapacke-3.5.0  
( part of the lapack-3.5.0 distribution  available from 
 ( http://www.netlib.org/lapack/ )
on a linux-installed  multilib computer.  The computer has these:

--cpu AMD64 4 cores
--os blfs linux  multilib  ( 64-bit and 32-bit libraries )
--gcc:4.9.2, linux-3.18.4
I tried to build the lapacke library twice  with switches
a) gcc -m64 and 
b) gcc -m32
lapacke-3.5.0 builds fine   with a )   (i.e. 64-bit library.  However it fails   
with the -m32 switch. 
The build ends   with something like so:-

############
/home/lusinteg/BUILD/lapack-3.5.0/lapacke/include/lapacke.h:16439:22: warning: 
parameter names (without types) in function declaration
                      const lapack_int* vers_patch );
                      ^
lapacke/CMakeFiles/lapacke.dir/build.make:54: recipe for target 
'lapacke/CMakeFiles/lapacke.dir/__/src/lapacke_cbbcsd.c.o' failed
make[2]: *** [lapacke/CMakeFiles/lapacke.dir/__/src/lapacke_cbbcsd.c.o] Error 
1
############

I would like to know if there are switches I could add to cflags or whatver to 
enable compilation with -m32 switch.  
(In a nutshell   advice on whether  the lapacke library  is makable  as a 32-
bit library and if so how so. )

Thanks in advance

Yours sincerely
