using dislin with Windows10/codeblocks/mingw C++ : linker error undefined ref. 'imp___iob_func'

[Bernhard ZEIMETZ]

Hello,

I would like to use dislin with codeblocks (v25.03, using mingw 14.02, windows 10)

I set up a very bare test programme (type "Win32 GUI project")

which in main.cpp has

 #include <discpp.h>  

and in WinMain() 

 Dislin g; 

//nothing else is called

Following advice in other threads, I set under 

Project > Build Options> Linker > other linker options:
  -mthreads
  ..\..\ExtLibs\dislin_gcc\discpp.a  -lgdi32 -luser32 -lopengl32

 

but I get a linker error 

undefined ref. to "__imp___iob_func"
(3X, in the same 3 (sub)files dis_win.cpp, errmes.cpp, resall.cpp)

I found online some infos on similar problems but with other compilers/languages/symbols, and the advice given there doesn't help. (eg adding other libraries)

Thanks in advance for any ideas or advice!

Hi,

please use the library discppu.a instead of discpp.a. discppu.a supports the ucrt runtime

library. I have tested it with  codeblocks v25.03, mingw 14.02 and Windows 11.

With best regards,

Helmut
