#71 MinGW make error

[Anonymous]

Hi,

I'm having an issue with getting the stack to build the basic examples. select() seems to be declared twice and I have been unable to find a solution or any topics related top this issue. Any insight to where I should look would be very appreciated.

Thank you

It is likely that the MSYS2 environment is not configured correctly.

Some background for configuration is here:
https://stackoverflow.com/questions/48031258/mingw64-and-conflicting-declaration-of-c-function-int-select

You can check the environment using uname and using gcc -dumpmachine

You can setup the MSYS2 for MinGW32 environment using the appropriate launcher.
https://www.msys2.org/wiki/Launchers/

The check results:

$ uname
MINGW32_NT-10.0-19045

$ gcc -dumpmachine
i686-w64-mingw32

To install from MSYS2, you can use winget and pacman:

c:\> winget install --id=MSYS2.MSYS2  -e

Launch MSYS and install the MinGW32 toolchain:

$ pacman -Syu
$ pacman -Sy base-devel
$ pacman -Sy mingw-w64-i686-toolchain

Note that I currently get a Linker (ld.exe) error when using MSYS MinGW32 shell.

C:/msys64/mingw32/bin/../lib/gcc/i686-w64-mingw32/13.1.0/../../../../i686-w64-mingw32/bin/ld.exe: cannot find -lbacnet: No such file or directory

I use git-bash with my ~/.bashrc file configured as:

$ cat ~/.bashrc
alias make=mingw32-make.exe
PATH=/c/msys64/mingw32/bin:$PATH
export MAKE=mingw32-make.exe
export CC=gcc.exe
export OBJCOPY=objcopy.exe
export AR=ar.exe
export NM=nm.exe
export STRIP=strip.exe
export SIZE=size.exe

and the checks return:

$ gcc -dumpmachine
i686-w64-mingw32

and

$ uname
MINGW64_NT-10.0-19045

My git-bash PATH starts with: /c/msys64/mingw32/bin:

For compiling under MinGW32, MSYS2 installation is:

c:\> winget install --id=MSYS2.MSYS2  -e

Start MSYS, and install MinGW32.

$ pacman -Syu mingw-w64-i686-toolchain

Then edit ~/.bashrc file and add:

alias make=mingw32-make.exe

Exit MSYS.
Start MSYS profile for MinGW32.
Verify MSYS profile:

$ uname
MINGW32_NT-10.0-19045

Verify GCC is targeting i686:

$ gcc -dumpmachine
i686-w64-mingw32

Verify make is built for Windows32:

 make --version
 Built for Windows32

Thanks Steve! Those solved the issue.
