Error message from configure

[David Crocker]

Hi, I am trying to build a MSW configuration of wxWidgets 3.1.1 using MinGW. I normally use Visual Studio for Windows builds, but the third-party project I am building uses GCC extensions to C++, so it needs a MinGW or Cygwin build instead.

First I installed mingw-w64 but unfortunately that doesn't include a command shell, so I was unable to run the 'configure' script to generate the necessary include files. So then I installed MSYS2 which is supposed to be mingw-w64 along with tools. I opened a MSYS2 shell in the wxWidgets folder and ran ../configure --disable-shared. This was the result:

>>

So I am reporting the build results here as requested in the message.

What is the correct way to do a MSW build using gcc these days? Once I have the configuration sorted out, I plan to use Eclipse (which has support for MINGW) as the build environment.

Hi,

You need to use the MinGW shell (MSYS2 MinGW 64-bit), not the MSYS2 shell.
And make sure all required packages are installed, I think you need at least msys2-devel and mingw-w64-x86_64-toolchain.

Hello David,

FWIW I think Cygwin is a better solution if you want to use configure (and
I do think that using configure is preferable to using makefile.gcc too).
While Cygwin has its problems, it's still a more consistent and stable
environment than various MinGW ones and you can perfectly well use more up
to date MinGW-w64 as a cross-compiler from Cygwin, as I do.

I'm afraid this is a generic error message from configure (which uses the
maintainers email address which is specified as wx-dev) and I don't know if
we can do anything about it. You should be able to find more details in
config.log


DC> What is the correct way to do a MSW build using gcc these days?

The 2 ways that are definitely supposed to work are:

1. Using Cygwin and configure.
2. Using plain MSYS with build\msw\makefile.gcc.

I _think_ it should also be possible to make configure work under some
MSYS environment somehow, but there are just too many of them, each
broken^H^H^H^H^H^H different in its own way, to ensure that all of them
work, I'm afraid.

Good luck!
