Configure says that pkg-config can’t find fontconfig.pc, but it seems to be
in the PKG_CONFIG_PATH.

Perhaps you should add the directory containing `fontconfig.pc'
to the PKG_CONFIG_PATH environment variable

Most likely the fontconfig package on your system is a shared library, it is 
not distributed as a static library. It therefor cannot be used in a static 
build with --disable-shared.


Try building ffmpeg with shared libraries if you need fontconfig.

Thank you.  Before changing all the ffmpeg dependencies to shared libraries,
I tried making a static fontconfig.  I removed the packaged fontconfig parts
and built my own static fontconfig, but got the same “fontconfig not found" 
error.
There is no .so file on the system with *fontconfig* in its name.

The relevant files may be:
/usr/local/ffmpeg/target/include/fontconfig/fontconfig.h
/usr/local/ffmpeg/target/lib/libfontconfig.la
/usr/local/ffmpeg/target/lib/pkgconfig/fontconfig.pc
/usr/local/ffmpeg/target/lib/libfontconfig.a



fontconfig.pc contains:
# cat /usr/local/ffmpeg/target/lib/pkgconfig/fontconfig.pc
prefix=/usr/local/ffmpeg/target
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include
sysconfdir=${prefix}/etc
localstatedir=${prefix}/var
PACKAGE=fontconfig
confdir=${sysconfdir}/fonts
cachedir=${localstatedir}/cache/${PACKAGE}

Name: Fontconfig
Description: Font configuration and customization library
Version: 2.15.0
Requires:  freetype2 >= 21.0.15
Requires.private:  libxml-2.0 >= 2.6
Libs: -L${libdir} -lfontconfig
Libs.private:
Cflags: -I${includedir}

fontconfig.pc seems to be pointing to the right places (except 
sysconfdir=${prefix}/etc doesn’t exist; I don’t know what it would be looking 
for there).  I’m perplexed.

Small error; ${prefix}/etc DOES exist.  It contains a fonts directory.


Many times the problem seems to actually be not finding lzma.
But I have --disable-lzma in my configure command.
Here’s the end of config.log this time:
. . .
brotlicommon -lxml2 -licui18n -licuuc -licudata -lz -llzma -lm
/usr/bin/ld: cannot find -llzma: No such file or directory
collect2: error: ld returned 1 exit status
ERROR: fontconfig not found using pkg-config


Problem solved, although a bit confusing.  It seems there
may have been two problems.  After I provided a static fontconfig,
it still complained that it couldn’t find fontconfig.  But really it was
lzma.  When I built a static lzma (actually xz, which also produces lzma),
the build worked fine.

So it seems the —disable-lzma option doesn’t work; it still
tries to incorporate lzma. But I don’t really understand it.



My guess is that fontconfig probably returns an error, because one of 
its dependencies (libfreetype) depends on several types of file 
compression. (there are many types of compressed fonts), WOFF being a 
common example.

Thank you.  Before changing all the ffmpeg dependencies to shared libraries, 
I tried making a static fontconfig.  I removed the packaged fontconfig parts 
and built my own static fontconfig, but got the same “fontconfig not found" 
error.  
There is no .so file on the system with *fontconfig* in its name.

sysconfdir=${prefix}/etc doesn’t exist; I don’t know what it would be looking 
for there).  I’m perplexed.

Most likely the fontconfig package on your system is a shared library, it is 
not distributed as a static library. It therefor cannot be used in a static 
build with --disable-shared.


Try building ffmpeg with shared libraries if you need fontconfig.

Allow me a third try:
You cannot report "FFmpeg's configure requires me to 
install gas-preprocessor for arm on OSX when using 
clang but I don't need it" because it is needed.

You can either install gas-preprocessor and use 
--disable-fft for the time being, compilation of the 
arm fft code currently fails with clang on osx, see 
ticket #5164.
Or you can use gcc for compilation (it does not need 
gas-preprocessor) as I believe you have already done.
Third possibility is to use clang but gcc for the 
asm, just add --as=/bin/arm-linux-androideabi-gcc 
to your configure script (no gas-preprocessor needed).

Instead of the (unsupproted) extra-cflags you are 
using, please pass --cpu=cortex-a8 to configure. 
If you believe this has any disadvantage please tell 
us so we can fix it.

[FFmpeg-user] Configure error with Android NDK clang compiler

[Marco Pracucci]

I successfully build and run in production ffmpeg on Android (arm and x86)
compiled with Android NDK's gcc. Recently, Android deprecated gcc and is
pushing every dev to migrate to clang.

I'm getting some issues while compiling ffmpeg with Android NDK's clang and
this is the first one I encounter:
*GNU assembler not found, install/update gas-preprocessor*

Despite the message, looks that error is more subtle, because it fails
while running "check_as" but if I run the same exact check command on the
terminal, *it works*.

Below you can find the full instructions to reproduce it (it fixes with
--disable-asm but with gcc I'm able to compile with asm support).

Versions:
- ffmpeg 2.8.4
- Compile on OSX 10.9.5

*Download Android NDK*
You can download the Android NDK from here:
​http://developer.android.com/ndk/downloads/index.html

*Install Android NDK*
Follow the installation instructions in the download and then set the
environment variable NDK_DIR to the directory where you extracted the NDK.

*Build NDK standalone toolchain*
Define an environment variable TOOLCHAIN_DIR with the full path of the
directory where the standalone toolchain should be installed. For example:
export TOOLCHAIN_DIR=/tmp/toolchain

Then build the toolchain:
${NDK_DIR}/build/tools/make-standalone-toolchain.sh \
--toolchain=arm-linux-androideabi-clang3.6 \
--platform=android-9 \
--install-dir=${TOOLCHAIN_DIR}

*Compile ffmpeg*
I use the following configure script:

I have not compiled FFMPEG for android using toolchain, however, I had a
tough time doing the same with opencv-JNI. This question, asked in
stackoverflow might help you.
http://stackoverflow.com/questions/34246265/opencv-ann-mlp-training-in-android

I read your ndk building procedure, don't you point Application.mk and
Android.mk files to your toolchain? I mean $NDK-PATH/ndk-build ? Are you
using gradle?

I can reproduce the error message.
I decided to install gas-preprocessor and this issue disappeared.
Why do you believe there is an issue that we can fix?

Note that since compilation does not succeed for all files, I 
suggest you use gcc for the time being.

Re: [FFmpeg-user] Configure error with Android NDK clang compiler

[Marco Pracucci]

Carl Eugen,
thanks for your reply.

> I decided to install gas-preprocessor and this issue disappeared.

For the sake of knowledge, I can't understand why I do need a
gas-preprocessor to run the configure. If I create a file containing the
same exact AS code run through "check_as" and run the same exact command to
compile it (I took both from --logfile content), it actually works.

Since there's some discrepancy between the command run by the configure
script and the same exact command run manually on my terminal, I'm
wondering how it could happen and if it's actually an issue related to the
configure script.

> Note that since compilation does not succeed for all files, I
> suggest you use gcc for the time being.

I manually patched the configure script to bypass "check_as" and I also
realized the compilation fails. That's the next thing I will deeply look
into.

Thank you,
Marco

AFAIU, you need an OpenCL loader and an actual implementation. See

Perhaps the ICD loader is sufficient for building. On Fedora, this
would be the package ocl-icd-devel.

I can't help you much further, due to lack of experience.

 With above ffmpeg change, Windows (MinGW?) user encounters libmodplug not

 This is because of mod plug.h's   MODPLUG_EXPORT macro.  The 
 macro is defined as __declspec(dllimport) would be added, without defining 
 MODPLUG_STATIC.  

Can you explain how this is different from before the pkg-config patch?

 Then, called as `_imp__ModPlug_Load' from ffmpeg configure, and then result 
 in libmodplug not found error.  (I'm not Windows user.  I'm writing the error 
 mechanism based on one of my friend's comment who using Windows)
 

 The countermeasure is either of bellow 3.
 1.Define MODPLUG_STATIC in modplug.h.

What is the consequence of this when it's not static?

 2.Add -DMODPLUG_STATIC to Cflags: -I${includedir} line in libmodplug.pc.

Sounds like you have to add this to Cflags.private or something so it's
raised with --static. You need to see this with modplug itself

 3.Configure ffmpeg with adding --extra-cflags=-DMODPLUG_STATIC option.
 

We indeed currently do #define MODPLUG_STATIC in the
libavformat/libmodplug.c itself, so it should probably be in the configure
test as well. Unfortunately, I'm not sure how this actually affects the
linking when only a shared version of the library is available. Also, I
don't understand how this previously worked, because the configure test
never had it.

There are no difference in mod plug.h between pkg-config patch and before.  
To build ffmpeg (Before pkg-config patch) with libmodplug support, Windows user 
modified ffmpeg configure script as my first message.  They added -lstdc++ to 
enabled libmodplug line as workaround.  

-enabled libmodplug require libmodplug libmodplug/modplug.h 
ModPlug_Load -lmodplug
+enabled libmodplug require libmodplug libmodplug/modplug.h 
ModPlug_Load -lmodplug -lstdc++

 Then, called as `_imp__ModPlug_Load' from ffmpeg configure, and then result

 The countermeasure is either of bellow 3.
 1.Define MODPLUG_STATIC in modplug.h.
 
 What is the consequence of this when it's not static?

Yes it's a workaround for ffmpeg static building.  If build ffmpeg as shared, 
this workaround is not needed.  

 2.Add -DMODPLUG_STATIC to Cflags: -I${includedir} line in libmodplug.pc.
 
 Sounds like you have to add this to Cflags.private or something so it's
 raised with --static. You need to see this with mod plug itself

You are right, but this is a workaround for ffmpeg static building too.  It 
does not mean that libmodplug.pc should be changed in it's source code.  

 3.Configure ffmpeg with adding --extra-cflags=-DMODPLUG_STATIC option.
 
 We indeed currently do #define MODPLUG_STATIC in the
 libavformat/libmodplug.c itself, so it should probably be in the configure
 test as well. Unfortunately, I'm not sure how this actually affects the
 linking when only a shared version of the library is available. Also, I
 don't understand how this previously worked, because the configure test
 never had it.


In fact, the error in Windows is not related with ffmpeg.  It is derived from 
macro in modplug.h.  Here   , I pickup central of this issue: 

01 #if defined(_WIN32) || defined(__CYGWIN__)
02 # if defined(MODPLUG_BUILD)  defined(DLL_EXPORT)   /* building libmodplug 
as a dll for windows */
03 #   define MODPLUG_EXPORT __declspec(dllexport)
04 # elif defined(MODPLUG_BUILD) || defined(MODPLUG_STATIC) /* building or 
using static libmodplug for windows */
05 #   define MODPLUG_EXPORT
06 # else
07 #   define MODPLUG_EXPORT __declspec(dllimport)  /* 
using libmodplug dll for windows */
08 # endif
09 /* FIXME: USE VISIBILITY ATTRIBUTES HERE */
10 #elif defined(MODPLUG_BUILD)
11 #define MODPLUG_EXPORT
12 #else
13 #define MODPLUG_EXPORT
14 #endif

You may see that without MODPLUG_STATIC definition, _imp__ prefix is added to 
function name.  All 3 countermeasure are workaround to

A information for Windows (MinGW?) user.  

With above ffmpeg change, Windows (MinGW?) user encounters libmodplug not found 
error when configuring ffmpeg with libmodplug-0.8.8.5.  
This is because of mod plug.h's MODPLUG_EXPORT macro.  The 
macro is defined as __declspec(dllimport) would be added, without defining 
MODPLUG_STATIC.  
Then, called as `_imp__ModPlug_Load' from ffmpeg configure, and then result in 
libmodplug not found error.  (I'm not Windows user.  I'm writing the error 
mechanism based on one of my friend's comment who using Windows)

The countermeasure is either of bellow 3.
1.Define MODPLUG_STATIC in modplug.h.
2.Add -DMODPLUG_STATIC to Cflags: -I${includedir} line in libmodplug.pc.
3.Configure ffmpeg with adding --extra-cflags=-DMODPLUG_STATIC option.

My friend told me that ffmpeg's require_pkg_config change in libmodplug is 
fair.  There are some libraries which have to add STATIC definition to build 
ffmpeg correctly.  

So please use either of 3 countermeasure to build ffmpeg with libmodplug 
support in Windows.

The creation of mod files is a complex process and can hardly be made

ffmpeg -i test.mod test.wav, or simply ffplay test.mod

[FFmpeg-user] configure error with enabling libmodplug

[Kimio Miyamura]

Hi, 

I'm trying to build ffmpeg with libmodplug codec.  
When I run ./configure --enable-libmodplug, it always ends with error 
libmodplug not found.

$ ./configure --enable-libmodplug
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr 
--with-gxx-include-dir=/usr/include/c++/4.2.1
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr 
--with-gxx-include-dir=/usr/include/c++/4.2.1
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr 
--with-gxx-include-dir=/usr/include/c++/4.2.1

--with-gxx-include-dir=/usr/include/c++/4.2.1
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr 
--with-gxx-include-dir=/usr/include/c++/4.2.1
ERROR: libmodplug not found

I searched web and found that modification of ffmpeg configure script is 
required: 
https://trac.macports.org/ticket/36942 https://trac.macports.org/ticket/36942

-enabled libmodplug require libmodplug libmodplug/modplug.h 
ModPlug_Load -lmodplug
+enabled libmodplug require libmodplug libmodplug/modplug.h 
ModPlug_Load -lmodplug -lstdc++

or

-enabled libmodplug require libmodplug libmodplug/modplug.h 
ModPlug_Load -lmodplug
+enabled libmodplug require libmodplug libmodplug/modplug.h 
ModPlug_Load -lmodplug -lc++


I have tested with Mac OS X.  Both of them (adding -lstdc++ or -lc++ to enabled 
libmodplug line) result in good.  I can build ffmpeg fine.  

I think either of them should be added to ffmpeg compile script.  How do you 
think?
