Handbrake: Building from source fails due to missing fftw3.h when compiling libsamplerate

Created on 28 Feb 2016 · 9Comments · Source: HandBrake/HandBrake

I am trying to build the latest HandBrake commit from source (as described here, but with the --enable-fdk option enabled). Compilation fails when trying to compile the libsamplerate tests, due to a missing fftw3.h header:

It seems that FFTW is not downloaded into the ./build/contrib directory, nor a relevant include path added. I have it installed via my package manager (i.e. find /usr/include/ -name "fftw3.h") returns the found header, but I assume that's not very useful for cross-compilation.

Indeed; I have just tried building according to the documentation using a fresh Ubuntu VM install. It succeeds out of the box, but as soon as I install FFTW:

sudo apt-get install libfftw3-dev

the build fails, as above.

I'm guessing your using the cross compiler that came with ubuntu? Last time I checked it wouldn't work.

See the doc folder for details on the supported version of mingw.

Nope, I am using the cross compiler that I downloaded as described here:

You will need a copy of their toolchain from http://sourceforge.net/projects/mingw-w64/files/?source=navbar
Please see "Toolchains targetting Win64" -> "Automated Builds" and choose the latest version.
At the time of writing, "mingw-w64-bin_x86_64-linux_20131228.tar.bz2" is used.

As far as I can tell, I have exactly followed the instructions in the documentation.

Able to provide a full build log from a clean checkout? Any old pastebin site link will do.

No problem, there you go:

Nothing steps out I'm afraid. It's probably something else on your path that's causing problems with the toolchain. Unfortunately I have no idea what.

All I can do is confirm the stated toolchain works on a clean ubuntu 15 install.

Removing unnecessary entries from my PATH did not change anything.
However, removing the system-installed FFTW3 library led to success:

sudo apt-get remove libfftw3-dev

followed by a clean HandBrake clone results in a successful build.
Which leads me to believe that, on a fresh Ubuntu install, installing the FFTW3 library will probably result in build failure, but I did not try this yet.
My suspicion is that some configure script (wrongly) sees the system-installed libfftw3-dev, records its presence such that some conditionally compiled code is activated, but then the system path /usr/local/include does not get added to the includes (and rightfully so).

If this can't be fixed easily, maybe this could be mentioned as a potential caveat in the build documentation?
