I just tried the latest available source code of TPT (80.3) that has been prepared for for Codeblocks (not the absolute latest version of TPT, but it is the latest available in a project format designed for Codeblocks).

However when I try to built it, it fails after compiling, just when it starts linking. I even made the changes recommended for an older version to get rid of some compiling problems (namely I removed -DGRAVFFT from compile options, and removed -lfftw3f from linker options). But it didn't work. I thought maybe a change fixed that old bug, and maybe even mandate those options, so I put those options back in, and it still didn't work. Below is the part of its compile log showing the errors:

Compiling: src\powder.c
Compiling: src\save.c
Compiling: src\update.c

lib\libregex.a(regex.o):regex.c:(.text+0x6ee5): undefined reference to `__chkstk_ms'

collect2: ld returned 1 exit status
Process terminated with status 1 (0 minutes, 49 seconds)
6 errors, 0 warnings (0 minutes, 49 seconds)

With those extra options removed, the errors look like this instead:

Process terminated with status 1 (0 minutes, 46 seconds)
5 errors, 0 warnings (0 minutes, 46 seconds)

In any case, they all are of the "undefined reference to `__chkstk_ms'" variety. PLEASE tell me what to do to fix the errors called "undefined reference to `__chkstk_ms'". Thanks in advance.

Bump. I still need help with this. Thanks in advance.
