Thread: compiling standalone progs with sac libraries on 64-bit

Dear Steve,

You need to add the math library (libm) that contains pow.

Add -lm to the end of the compile line or to LIB

Hi,

I am trying to compile a standalone progam using the sac libraries
on a machine running 64-bit Fedora 13. I have the most recent 64-bit
executables, sac-101.4-linux-x86_64.

my makefile contains
LIB = -L/usr/local/sac/lib -lsacio
sac2rsam: sac2rsam.o
gcc -c sac2rsam.c -o sac2rsam.o $(LIB)
gcc -o sac2rsam sac2rsam.o $(LIB)

This gives an error:
make sac2rsam
gcc -c sac2rsam.c -o sac2rsam.o -L/usr/local/sac/lib -lsacio
gcc -o sac2rsam sac2rsam.o -L/usr/local/sac/lib -lsacio
/usr/local/sac/lib/libsacio.a(math.o): In function `powi':
math.c:(.text+0xf1): undefined reference to `pow'
collect2: ld returned 1 exit status
make: *** [sac2rsam] Error 1

If I assume sacio is 32-bit and add -m32 after gcc in my makefile I
get a different error:
make sac2rsam
gcc -m32 -c sac2rsam.c -o sac2rsam.o -L/usr/local/sac/lib -lsacio
In file included from /usr/include/features.h:385,
from /usr/include/stdio.h:28,
from sac2rsam.c:5:
/usr/include/gnu/stubs.h:7:27: error: gnu/stubs-32.h: No such file
or directory
make: *** [sac2rsam] Error 1

Does anyone know how I should proceed?

Many thanks

Hi

Does you have the necessary files to compile 32bits code installed in your
fedora ? Normally you would need some 32 bits header files. Something like
libc32-dev, or libgcc32-dev or something like this ....

regards,

Marcelo
