Cannot build exampls/simple.c

[marioguerriero]

Running "make simple" I got the following error:

gcc -o sprec_simple examples/simple.o -lsprec
/usr/bin/ld: examples/simple.o: undefined reference to symbol 'pthread_join@@GLIBC_2.0'
/usr/bin/ld: note: 'pthread_join@@GLIBC_2.0' is defined in DSO /lib/i386-linux-gnu/libpthread.so.0 so try adding it to the linker command line
/lib/i386-linux-gnu/libpthread.so.0: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
make: *** [sprec_simple] Error 1

Oh yes, that's a difference between Linux and OS X (what this library is being developed on). What happens when you add -lpthread to the end of the linker flags?

I get the following error:

gcc -o sprec_simple examples/simple.o -lsprec -lpthread
/usr/lib/gcc/i686-linux-gnu/4.7/../../../../lib/libsprec.so: undefined reference to `alloca'
collect2: error: ld returned 1 exit status
make: *** [sprec_simple] Error 1

it's the same error I get while running "make tool"

Now that is weird. The code doesn't even use alloca(). Are you sure your installation of GCC and the C development libraries is correct?

[marioguerriero]

I installed gcc from Ubuntu 13.04 repo. I think C development libraries are correct. Can you mentaion what packages do I have to install?

I just tried to reinstall libsprec and not it works fine. Thank you for the help.

You are welcome, I'm glad it worked out.
