I've downloaded dhex_0.69.tar.gz from http://www.dettus.net/dhex/ and unpacked it. The Readme says simply to run make.



When I try to build it in MSYS2 shell on Windows 10, compilation and linking proceed without any problems, I get an .exe, which works fine:

However, this .exe will then depend on msys-ncursesw6.dll and msys-2.0.dll when ran outside of the MSYS shell (so, when ran in Command Prompt cmd.exe, which does raise an error - or in Power Shell, which does not raise an error; the program simply exits there).



So, I wanted to try and build it in MINGW64. Compilation completes, but with warning - and linking fails due to undefined reference to '_impure_ptr':

However, this .exe will then depend on msys-ncursesw6.dll and msys-2.0.dll when ran outside of the MSYS shell (so, when ran in Command Prompt cmd.exe, which does raise an error - or in Power Shell, which does not raise an error; the program simply exits there).



So, I wanted to try and build it in MINGW64. Compilation completes, but with warning - and linking fails due to undefined reference to '_impure_ptr':

I've downloaded dhex_0.69.tar.gz from http://www.dettus.net/dhex/ and unpacked it. The Readme says simply to run make.



When I try to build it in MSYS2 shell on Windows 10, compilation and linking proceed without any problems, I get an .exe, which works fine:

I downloaded the package in question and figured out how to compile it with the MinGW-w64 64-bit toolchain provided by MSYS2.



First of all, install the relevant development tools and libraries:



pacman -S base-devel mingw-w64-x86_64-ncurses,toolchain


Next, you need to edit the Makefile that comes with the package. The LDFLAGS, CPPFLAGS, and CFLAGS values must be modified to the following:



LDFLAGS=
CPPFLAGS= -I$(MINGW_PREFIX)/include/ncurses
CFLAGS= -D__USE_MINGW_ANSI_STDIO=1 -O3 -Wall


Some explanation: It is very bad that the Makefile has hardcoded paths in LDFLAGS and CPPFLAGS, because if you were to use those paths then you would be using files from another toolchain (the msys-2.0.dll-based one). So we need to get to get rid of those. Also, to get rid of all the warnings about printf formatting, we must supply the -D__USE_MINGW_ANSI_STDIO argument.



Then, just run make.

        Next, you need to edit the Makefile that comes with the package. The LDFLAGS, CPPFLAGS, and CFLAGS values must be modified to the following:



        LDFLAGS=
        CPPFLAGS= -I$(MINGW_PREFIX)/include/ncurses
        CFLAGS= -D__USE_MINGW_ANSI_STDIO=1 -O3 -Wall


        Some explanation: It is very bad that the Makefile has hardcoded paths in LDFLAGS and CPPFLAGS, because if you were to use those paths then you would be using files from another toolchain (the msys-2.0.dll-based one). So we need to get to get rid of those. Also, to get rid of all the warnings about printf formatting, we must supply the -D__USE_MINGW_ANSI_STDIO argument.



        Then, just run make.

        I downloaded the package in question and figured out how to compile it with the MinGW-w64 64-bit toolchain provided by MSYS2.



        First of all, install the relevant development tools and libraries:



        pacman -S base-devel mingw-w64-x86_64-ncurses,toolchain


        Next, you need to edit the Makefile that comes with the package. The LDFLAGS, CPPFLAGS, and CFLAGS values must be modified to the following:



        LDFLAGS=
        CPPFLAGS= -I$(MINGW_PREFIX)/include/ncurses
        CFLAGS= -D__USE_MINGW_ANSI_STDIO=1 -O3 -Wall
