Core dumped with test prog.

Core dumped with test prog.

[F. Schoenahl]

Hi, 
	I receive a core dumped when trying to execute a small binary (GCC 2.95.3, Solaris Sparc 2.7) compiled with 
	gcc -g main.c  -o sample -lgsl -lgslcblas
main.c is the example program of the documentation (bessel_sf_J0).

Here are some details: 

uname -a 
	SunOS ultraphys 5.7 Generic_106541-20 sun4u sparc
gcc --version
	2.95.3
gcc -dumpmachine
	sparc-sun-solaris2.7
gdb (>>run)
	Program received signal SIGSEGV, Segmentation fault.
	0xff31a958 in __do_global_ctors_aux () from /usr/local/lib/libgsl.so.0
Any help? 
I can send the core file to a personal adress if someone can use it.

Thanks a lot,

Try explicitly linking with the static version library 

 gcc -g main.c  -o sample /usr/local/lib/libgsl.a /usr/local/lib/libgslcblas.a

to see if the problem is related to shared libraries on Solaris.

That's it!

I just had to add "-lm" to your line, the binary is now OK.. 

Keep on the good work on the library... I stay at disposition if I can help more on this problem.
