new iphreeqc lib

[olegmelnik-ascension]

could you compile and release new iphreeqc 3.8.6 library for linux and windows?

[simulkade]

Oh, it's been a while that I have updated these libraries! I will give it a shot later tonight.

Unable to create IPhreeqc instance: There was an error loading the library libiphreeqc.dll The specified procedure could not be found.
Does anyone have the same issue? phreeqcrm works fine.

[simulkade]

Could you provide more details? Operating system? Etc. I cannot reproduce the issue.

@olegmelnik-ascension I cannot reproduce it. It works fine for me. I usually have a ton of different compilers installed so it is hard to test it on a fresh system. Do you have a the visual studio with C++ compiler installed? I have VS 2022 on my system.

[olegmelnik-ascension]

Do you have a the visual studio with C++ compiler installed? - No, I use MinGW 8.1 C/C++.

[simulkade]

Usually, installing visual studio community edition (free) solves the problem. I do understand that it takes a lot of space on the hard drive.

I will do it, thanks!

I will do it, thanks!
Have you solved the problem yet? I have the same problem as well. I downloaded VS2022, but the problem still persists. Maybe it's because it's not compatible with the new version of PhreeQC?

After installing VS, make sure that the C++ compilers are also installed. The easiest way is to create a new C++ project in VS and it will automatically download the compilers for you.
