I've decided to write an simple audio converter in objective-c and cocoa, but i cannot link libFlac C library to my Xcode project. When i'm trying to do this, compiler says:
ld: symbol(s) not found for architecture x86_64
What's more, when i'm trying to compile it via command line tools (just like it is described in readme file), terminal throws:
ot match previous archive members cputype (16777223) (all members must
match) ranlib: for architecture: x86_64 file: .libs/libFLAC.a(float.o)
has no symbols make[4]: * [libFLAC.la] Error 1 make[3]:
[all-recursive] Error 1 make[2]: [all-recursive] Error 1 make[1]:
* [all-recursive] Error 1
And when I changed target architecture to intel 32-bit:
error: -fobjc-arc is not supported with fragile abi
Command >/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang >failed with exit code 1
Can anybody help me ? Maybe somebody knows about better, easier way for decoding FLAC files in objective-c ?
./configure --disable-asm-optimizations && make
This will build correctly on OS X.

any ideas for this?

I am stuck. Don't know what to try to solve this issue.
I did not find anything anywhere ...
Working on it for most of 2 days, I did find this site that presents a working method of building libx265 stuff on Apple Silicon and works for me on macOS 13.0.1. https://www.osxexperts.net/ Problem is, it only builds the libraries for building it into ffmpeg, no executable binary.
When I tried to get the executable also, by removing -DENABLE_CLI=OFF from the last cmake command, the error comes back. Put it back in, everything completes without error.
Here is the full process that works for me (no executable). It builds a multilibrary that can encode 8, 10, or 12-bit video:
cd x265/source
#### 12 bit
cmake -DCMAKE_INSTALL_PREFIX:PATH=${TARGET} -DHIGH_BIT_DEPTH=ON -DMAIN12=ON -DENABLE_SHARED=NO -DEXPORT_C_API=NO -DENABLE_CLI=OFF .
make
mv libx265.a libx265_main12.a
make clean-generated
rm CMakeCache.txt
#### 10bit
cmake -DCMAKE_INSTALL_PREFIX:PATH=${TARGET} -DHIGH_BIT_DEPTH=ON -DMAIN10=ON -DENABLE_SHARED=NO -DEXPORT_C_API=NO -DENABLE_CLI=OFF .
make clean
make
mv libx265.a libx265_main10.a
make clean-generated && rm CMakeCache.txt
#### 8 bit and all together
# removed -DENABLE_CLI=OFF from last one so we get the x265 binary
cmake -DCMAKE_INSTALL_PREFIX:PATH=${TARGET} -DEXTRA_LIB="x265_main10.a;x265_main12.a" -DEXTRA_LINK_FLAGS=-L. -DLINKED_10BIT=ON -DLINKED_12BIT=ON -DENABLE_SHARED=OFF -DENABLE_CLI=OFF .
make clean
make
mv libx265.a libx265_main.a
# this is Apple's libtool
libtool -static -o libx265.a libx265_main.a libx265_main10.a libx265_main12.a
make install
When I remove the last -DENABLE_CLI=OFF, here's the error:
[100%] Linking CXX executable x265

EDIT: #Peter Betz, see the issue report. Until the developers correct this error, it will compile if you edit x265/source/common/aarch64/pixel-util.S, line 2410. Add an underscore as follows. Change:
movrel x1, x265_entropyStateBits
to
movrel x1, _x265_entropyStateBits
I can't compile my titanium + hyperloop application. The compiler complains about the filesize of my libhyperloop.a, which is 2 bytes. Does this mean the file is corrupt, and does someone knows a workaround? I have inspected the file in both hyperloop 1.1.0 and 1.2.0 and both have the same file size.
ld: file too small (length=2) file '/Users/david/Projects/app/modules/iphone/hyperloop/1.1.0/libhyperloop.a' for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Can it be that my libhyperloop.a is corrupt? And does someone knows where to obtain a fully functional version of the hyperloop module?
I am trying to build CMake 3.5.2 from source on Mac El Captain using GNU GCC 5.3 from HPC.
The ./bootstrap process is completed successfully but when i am using make is failing with the following error.
/Users/dev/Downloads/CMake-master/Utilities/cmcurl/lib/vtls/darwinssl.c: In function ‘darwinssl_connect_step3’:
/Users/dev/Downloads/CMake-master/Utilities/cmcurl/lib/vtls/darwinssl.c:1999:6: error: ‘SecTrustEvaluateAsync’ undeclared (first use in this function)
if(SecTrustEvaluateAsync != NULL) {

make: *** [all] Error 2
The same process worked fine when I was using the default clang compiler provided with Mac OS.
When I tried finding about SecTrustEvaluateAsync I found the following information in the apple site.
Any help on this is highly appreciated.
You might try the latest CMake 3.6-rc1. If the problem persists, file a bug to notice the CMake developers. We probably won't fix CMake's code.
FreeType build system -- automatic system detection
The following settings are used:
platform unix
compiler xcrun clang
configuration directory ./builds/unix
configuration rules ./builds/unix/unix.mk
If this does not correspond to your system or settings please remove the file
`config.mk' from this directory then read the INSTALL file for help.
Otherwise, simply type `/Applications/Xcode.app/Contents/Developer/usr/bin/make' again to build the library,
or `/Applications/Xcode.app/Contents/Developer/usr/bin/make refdoc' to build the API reference (the latter needs python).

VLC Compiling Error
hope someone can me help. I need to compile some code. I installed everything I needed with macports, in /opt/local/. And it's working how it should, except gFortran. I get this error:
ld: library not found for -lgfortran
collect2: ld returned 1 exit status
make[2]: *** [vigranumpy/private/graph/tws/svs.dylib] Error 1
make[1]: *** [vigranumpy/private/graph/tws/CMakeFiles/svs.dir/all] Error 2
make: *** [all] Error 2
I want everything to be installed in /opt/local/, because I don't want to touch the system (/usr/). gFortran isn't available for macports. You can install it with gcc46 as a variant. But if I use the gcc46 instead the default compilers, then the code before want compile.
How can I fix that?
Kind regards
See the CMake FAQ on how to use a different compiler:
http://www.cmake.org/Wiki/CMake_FAQ#How_do_I_use_a_different_compiler.3F
To use gfortran from macports as the fortran compiler, you should:
export FC=/opt/local/bin/gfortran
export CC=/opt/local/bin/gcc
export CXX=/opt/local/bin/g++
...prior to calling CMake. Then, after calling CMake with such environment variables set, it will cache the compiler paths in the CMakeCache.txt file, so for subsequent runs, you do not need the environment variables set anymore.
For mixed language (C, C++, Fortran) projects, it's important that the compilers all play nicely with each other.
This advice only works with the "Unix Makefiles" generator. I do not know of anybody who is using fortran via Xcode in conjunction with CMake.
