Build scripts for building ffmpeg on iPhone

Hi there 👋

ffmpeg-iphone-build's Issues

No Working C Compiler found

Hi,

I am using build-armv6 build to compile the x264 using gcc4.2. Unfortuantely when I run the below command

CC=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2 ./configure --host=arm-apple-darwin --sysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.0.sdk --prefix='dist' --extra-cflags='-arch armv6' --extra-ldflags='-arch armv6' --enable-pic --disable-asm

I get No working C compiler found.

Any help to compile x264 and link to ffmpeg is highly appreciated.

Thanks,
/D

x264 fails to compile with armv6, armv7 and sdk3.0 or sdk3.2

Hi,

First thanks for our scripts ^^ it's the holly grail !!

I've got this error when I run build-x264-armv6 and build-x264-armv7

/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2 -O3 -fno-fast-math -Wall -I. --sysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.0.sdk -arch armv6 -falign-loops=16 -std=gnu99 -fPIC -s -fomit-frame-pointer -c -o encoder/me.o encoder/me.c
encoder/me.c: In function ‘x264_me_search_ref’:
encoder/me.c:249: warning: passing argument 1 of ‘x264_predictor_roundclip’ from incompatible pointer type
encoder/me.c:253: warning: cast to pointer from integer of different size
encoder/me.c:255: error: subscripted value is neither array nor pointer
encoder/me.c:256: error: subscripted value is neither array nor pointer
encoder/me.c:264: error: subscripted value is neither array nor pointer
encoder/me.c:265: error: subscripted value is neither array nor pointer
make: *** [encoder/me.o] Error 1
Installed: x264-armv6/dist

I think it's more a bug from x264 sources I check out. But it works for i386

Can not be compiled libswsca.a.

Hi, gabriel.
how do you do?

Can not be compiled libswsca.a.
I'm not sure but before I upgrade Xcode 3.2.5, I could.

Look for this post. To work fine script may be changed.

x264 fails to use in x264_encoder_encode

i compile x264 with build-x264-i386 setting

when my code run in x264_encoder_encode , the program will be crashed

the error information is
"Detected an attempt to call a symbol in system libraries
that is not present on the iPhone:__isfinited called from function
get_qscale in image ffmpeginiphone.
If you are encountering this problem running a simulator binary within gdb,
make sure you 'set start-with-shell off' first."

any body have any relative experience ??
thx

gcc-4.2 is unable to create an executable file

Hi, gabriel.
how do you do?

build-armv6/7 could compile, but today I tried it,I couldn't.
I'm not sure but before I upgrade Xcode 3.2.3, I could.
