Hi,
I'm actually trying to precompile our library. This seems to necessitate
putting some of the initialisation code we had in an __init__ function.
But I'm having problems with the cglobal syntax.
According to the documentation, it takes a tuple with exactly the same
format as ccall.
But this works inside __init__:
ccall((:pari_init, "$pkgdir/local/lib/libpari"), Void, (Int, Int),
3000000000, 10000)
But this does not:
global avma = cglobal((:avma, "$pkgdir/local/lib/libpari"), Ptr{Ptr{Int}})
The complaint is below. Can someone help me?
Note that if I change that string to just :libpari, it complains that
libpari is not found. This is despite me dlopen'ing libpari earlier in
__init__.
I have also set Libdl.DL_LOAD_PATH (I am on Linux) in __init__.
This all works fine if I put the code outside of __init__, but then I can't
precompile. As soon as I put it inside __init__, it no longer seems to work.
Bill.
