Are you running on Debian???  For some reason, on Debian autoconf/configure
seems to think there is a workable makecontext/getcontext/setcontext.   You
can build it using the following command line:
     ./configure --with-mctx-mth=sjlj --with-mctx-dsp=ssjlj
--with-mctx-stk=sas --with-param=install

Let me know if it doesn't work.

Hi,

I tried to recompile ngpt 0.9.5 from source, but it fails with
pth_lib.c: In function `pth_getcontext':
pth_lib.c:442: structure has no member named `jb'

I've checked pth_p.h and have no idea of how it supposed to work. It
contains the following definition
typedef struct pth_mctx_st pth_mctx_t;
struct pth_mctx_st {
#if PTH_MCTX_MTH(mcsc)
    ucontext_t uc;
#elif PTH_MCTX_MTH(sjlj)
    pth_sigjmpbuf jb;
#else

One line of ./configure output was:
decision on mctx implementation... mcsc/sc/mc

but pth_lib.c unconditionally uses mctx_t->jb.

HOW should I compile this stuff??
