Hi,

I am starting to experiment with multithreading packages to see how
they work and would like to use a standard package (that is POSIX
compatible) and as such I have downloaded the PTHREADS library from
FSUni and built it without a problem. When I tried to build the example
program in the readme file
it gives the following error:

c:/djgpp/lib/libc.a(sigprocm.o)(.text+0x1b8):sigprocm.c: multiple
definition of
`sigpending'
../lib/libgthreads.a(signal.o)(.text+0x1940):signal.c: first defined
here

Does anyone know how to correctly resolve this error?


Regards,
Andrew
