@chapter Platform Specific information
-@section BSD
+@section BeOS
+
+BeOS support is broken in mysterious ways.
+
+@section DOS
+
+Using a cross-compiler is preferred for various reasons.
+
+@subsection DJGPP
+
+FFmpeg cannot be compiled because of broken system headers, add
+@code{--extra-cflags=-U__STRICT_ANSI__} to the configure options as a
+workaround.
+
+@section OS/2
+
+For information about compiling FFmpeg on OS/2 see
+@url{http://www.edm2.com/index.php/FFmpeg}.
+
+@section Unix-like
+
+Some parts of FFmpeg cannot be built with version 2.15 of the GNU
+assembler which is still provided by a few AMD64 distributions. To
+make sure your compiler really uses the required version of gas
+after a binutils upgrade, run:
+
+@example
+$(gcc -print-prog-name=as) --version
+@end example
+
+If not, then you should install a different compiler that has no
+hard-coded path to gas. In the worst case pass @code{--disable-asm}
+to configure.
+
+@subsection BSD
BSD make will not build FFmpeg, you need to install and use GNU Make
(@file{gmake}).
+@subsubsection FreeBSD
+
+FreeBSD will not compile out-of-the-box due to broken system headers.
+Passing @code{--extra-cflags=-D__BSD_VISIBLE} to configure will work
+around the problem. This may have unexpected sideeffects, so use it at
+your own risk. If you care about FreeBSD, please make an attempt at
+getting the system headers fixed.
+
+@subsection (Open)Solaris
+
+GNU Make is required to build FFmpeg, so you have to invoke (@file{gmake}),
+standard Solaris Make will not work. When building with a non-c99 front-end
+(gcc, generic suncc) add either @code{--extra-libs=/usr/lib/values-xpg6.o}
+or @code{--extra-libs=/usr/lib/64/values-xpg6.o} to the configure options
+since the libc is not c99-compliant by default. The probes performed by
+configure may raise an exception leading to the death of configure itself
+due to a bug in the system shell. Simply invoke a different shell such as
+bash directly to work around this:
+
+@example
+bash ./configure
+@end example
+
@section Windows

@subsection Compilation under Cygwin
-The main issue with the 1.5.x Cygwin versions is that newlib, its C library,
-does not contain llrint(). You need to upgrade to the unstable 1.7.x versions,
-or leverage the implementation in MinGW (as explained below).
+Please use Cygwin 1.7.x as the obsolete 1.5.x Cygwin versions lack
+llrint() in its C library.
-Just install your Cygwin with all the "Base" packages, plus the
+Install your Cygwin with all the "Base" packages, plus the
following "Devel" ones:
@example
-binutils, gcc-core, make, subversion, mingw-runtime
+binutils, gcc4-core, make, subversion, mingw-runtime, texi2html
@end example
And the following "Utils" one:
diffutils
@end example
-The experimental gcc4 package is still buggy, hence please
-use the official gcc 3.4.4 or a 4.2.x compiled from source by yourself.
-
-Install the current binutils-20080624-2 as they work fine (the old
-binutils-20060709-1 proved buggy on shared builds).
-
-Then create a small library that just contains llrint():
-
-@example
-ar x /usr/lib/mingw/libmingwex.a llrint.o
-ar cq /usr/local/lib/libllrint.a llrint.o
-@end example
-
Then run
@example
-./configure --enable-static --disable-shared --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
+./configure --enable-static --disable-shared
@end example

+to make a static build.
+
+The current @code{gcc4-core} package is buggy and needs this flag to build
+shared libraries:
@example
-./configure --enable-shared --disable-static --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
+./configure --enable-shared --disable-static --extra-cflags=-fno-reorder-functions
@end example
-to build shared libraries.
-
If you want to build FFmpeg with additional libraries, download Cygwin
"Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
@example
./configure --target-os=mingw32 --enable-memalign-hack --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
