Nonexistance of `int _ada_use_c2phc4c ( int task, int *a, int *b, double *c, int v );` symbol in `.so` file

[nook0110]

I was using a C (C++) interface of this library, and noticed, that libPHCpack.so doesn't have a symbol for function _ada_use_c2phc4c

(But has a lot of calls)

nm -gD libPHCpack.so | grep ada

I replaced all calls of it on call of _ada_use_c2phc, everything works (fine?). But i think it isn't an intended solution)

So i think you should change in building cfg something for appearance of this symbol in .so file.

Everything should indeed work fine when calling _ada_use_c2phc. The use_c2phc is a wrapper to use_c2phc4c, with in addition the DEMiCs software, which is written in C++. The naming is more historical than that it is logical.

@janverschelde
Yeah, but you are calling _ada_use_c2phc4c
example:

PHCpack/src/C/celcon.c

Line 10 in 10adfbb

fail = _ada_use_c2phc4c(80,a,b,c,0);

which is not located in lib file

I manually replaced all calls of it with _ada_use_c2phc, so it would compile in my project

Ok, I see now. Thanks for reporting this issue.
