CLI Compile error under minGW

[Shatian]

I have been compiling the CLI under ubuntu minGW for a little while now, until I updated past rev 3266. 3266 compiles fine, but 3267, which updates ffmpeg, and a few other things,fails to compile. I know it's been a little while since this was patched, but I don't compile every night.

Here's the error log:

Any idea why this is failing?

[s55]

in the build dir

make ffmpeg.xclean
make

[Shatian]

Same results. I remove the build directory before I run configure...

[s55]

Probably dying for the same reason the nightly is. Someone will fix it when they have time to get around to it

[Shatian]

Ok. Thanks.

I tested building mingw before the last ffmpeg bump was committed. It worked then. So I just did a make xclean; make. Works now as well. So I thought, maybe I should replicate your steps completely and remove the build directory. Still works. Don't know what else to try. I use fedora which has a more complete mingw set of packages.

[Shatian]

Oddly enough, I could never get it to compile under fedora, always failed then too. I installed ubuntu, worked ok until yesterday when I updated to the newest revision. This morning I did a svn up -r 3266 HandBrake, then a rm -r -f build, then ./configure --cross=i586-mingw32msvc --launch. Compile successfully. I then did svn up -r 3267 HandBrake, then a rm -r -f build, then ./configure --cross=i586-mingw32msvc --launch. And got the error message above. Just tried it again to make sure, same result. I'm at a loss too.

[Shatian]

Found the problem, in case anyone is interested. ffmpeg added check_cflags -Werror=missing-prototypes to configure, and the version of mingw32 that comes with ubuntu (4.2) doesn't like that. The version that comes with fedora is newer (4.4). I still can't get it to compile on fedora though, bombs out when it tries to create hb.lib with a lot of undefined references in libdvdread.a and libx264.a.

Thanks for looking into this for me though.

[JohnAStebbins]

Yes, fedora's *complete* mingw distribution does a little more than you want. For starters, it installs wine and enables automatic execution of windows executables. This breaks many configure scripts that attempt to run an exe that they build in order to determine if you are cross compiling or not. So configure guesses wrong and ends up building with incorrect options. So you need to open System->Administration->Services and disable wine and make sure it doesn't run it the next time you boot.

In addition, our build system builds a local copy of pthreads that conflicts with the pthreads lib fedora installs. So you need to uninstall mingw's pthreads lib.

And finally, libdl (dlopen and friends) doesn't work properly with the way we configure libdvdread. So you need to uninstall mingw's libdl.

Excellent, that did the trick, thanks!

Hi guys!

I was having the same issue compiling under Ubuntu (clean install this week) and noticed that if I installed the mingw32 packages i get

Code: Select all

/usr/bin/i586-mingw32msvc-gcc --version
i586-mingw32msvc-gcc (GCC) 4.2.1-sjlj (mingw32-2)

But there is another package called gcc-mingw32 which gives you

Code: Select all

/usr/bin/i586-mingw32msvc-gcc --version
i586-mingw32msvc-gcc (GCC) 4.4.2
Copyright (C) 2009 Free Software Foundation, Inc.

It seems a little strange to get two different versions of the same software in a repo, but the newer version works for me at compiling the latest build.

Hope this helps others.

Thank you, NaVVy, that did the trick for me as well (Ubuntu 10.04 LTS).

Code: Select all

$ sudo apt-get remove mingw32
$ sudo apt-get install gcc-mingw32
$ ./configure --cross=i586-mingw32msvc --launch-jobs=1 --launch --force
