How to compile CLucene for iOS? - iphone

I am trying to compile CLucene for iOS and running into some problems.
Here are the steps I've taken
Modify the CLucene CMakeLists.txt to disable multithreading
Create a "build-ios" directory in the CLucene source directory
Drop the cmake file from this site into the cmake directory http://code.google.com/p/ios-cmake/
run the following command "cmake -DCMAKE_TOOLCHAIN_FILE=./iOS.cmake -GXcode ../"
Here's the output from that command. Can someone help me out with the error?
-- Toolchain using default iOS SDK: /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk
-- Looking for include files CMAKE_HAVE_PTHREAD_H

Thanks for your help!

looks like boost is missing. boost is a required library - check the readme

I know its been long. But just try Cmake with Zlib. Because i am in the process of doing the same thing you did, but waiting till i receive the MAc mini. If you have found the solution please do share because it will be helpful for me and many others. Thank you.

Target dart2js failed No such file or directory

I am running into an issue where on GH Actions my dart build is failing with lots of lines like
Compiling lib/main.dart for the Web...
Target dart2js failed: Exception: lib/api/file_a.dart:00:0:
Error: Error when reading 'lib/models/file_b.dart': Error reading 'lib/models/file_b.dart' (No such file or directory)
import "/models/file_b.dart";
Posted to answer right away in case it helps someone else.
My issue was because I changed the capitalization of files in git. from /File.dart to /file.dart.
The way to fix this was for each import unable to be found to git mv /File.dart /file.dart

linphone-sdk compilation error - Could not find a support sound driver API

I am trying to compile linphone-sdk on Centos 7.8 and got the following error.
Call Stack (most recent call first):
cmake/FindBV16.cmake:40 (find_package_handle_standard_args)
CMakeLists.txt:190 (find_package)
This warning is for project developers. Use -Wno-dev to suppress it.
CMake Error at CMakeLists.txt:327 (message):
Could not find a support sound driver API. Use -DENABLE_SOUND=NO if you
don't care about having sound.
After that, I did a
cmake -DENABLE_SOUND=NO ..
and rebuilt
cmake --build .
but still got the same error. Any idea?
The system has the alsa-lib installed
alsa-plugins-pulseaudio-1.1.6-1.el7.x86_64

Building Swift on CentOS

I am building Swift compiler from source on CentOS 6, and am running into a library issue. After fighting with the build script for a while I have got where running ./utils/build-script eventually gives:
+ /home/src/cmake-3.4.1-Linux-x86_64/bin/cmake --build /home/src/swift/build/Ninja-DebugAssert/cmark-linux-x86_64 -- all

/opt/gcc-4.8.2/lib64/libatomic.so.1
/opt/gcc-4.8.2/lib64/libatomic.so.1.0.0
I just don't know how to tell the build system where to look. I have tried the usual CMAKE_LIBRARY_PATH (exporting on the command line - I am not sure if cmake works like the way LD_LIBRARY_PATH, LIBRARY_PATH work) but it can't seem to find it.
I also don't have root on the machine.
I had not tried building from source on CentOS 6 until I saw this question, but I have been able to build Swift 2.2 on CentOS 7.1 and Ubuntu 14.04, with partial success. A few things to think about:
You will need numerous dependencies required to build Swift, and unless
they happen to be already on the system, you will need root access to
install them.
Use -R flag with the build-script to create a release build.
Building in DebugAssert (the default) will require a lot of memory. In my case even 14 GB was not sufficient. A release build
can be done with about 6 GB.
As for your specific problem, it is related to Clang's dependency on GCC-related packages for headers and libraries. See, for example, Fedora 21 with clang, without gcc.
Even if you installed GCC 4.8.2 and adjusted the path to use gcc and g++ from 4.8.2, Clang may still be looking in the old GCC directories for headers and libraries. CMake first tries to compile a C++ test file that includes the header atomic, which does not exist in the old GCC. So, it then tries to link a C test program that uses the library libatomic, which again doesn't exist in the old GCC. You can see this by looking at llvm/cmake/modules/CheckAtomic.cmake mentioned by usr1234567. CMakeError.log and CMakeOutput.log can also provide valuable insight. BTW, when I was building Swift on CentOS 7.1, I didn't run into this problem because GCC 4.8.2 was used by Clang for headers and libraries and the atomic header was found, so the C++ file got compiled. However, had the libatomic check been done, it would have failed, because libatomic.so in the repository-provided 4.8.2 has INPUT ( <name of some non-existent file> ), so trying to link with libatomic errors out.
I'm sure there are various ways of dealing with this issue, but what solved the problem for me was setting the following environment variables, please adjust to your specific setup:
export CPLUS_INCLUDE_PATH=/opt/gcc-4.8.2/include/c++/4.8.2:/opt/gcc-4.8.2/include/c++/4.8.2/x86_64-unknown-linux-gnu
export LIBRARY_PATH=/opt/gcc-4.8.2/lib64:/opt/gcc-4.8.2/lib/gcc/x86_64-unknown-linux-gnu/4.8.2
Also make sure that your 4.8.2 version of libstdc++.so is available to the dynamic linker at runtime. Since you don't have root, do
export LD_LIBRARY_PATH=/opt/gcc-4.8.2/lib64
If you had root, you could use ldconfig.
Before you start building Swift, you may want to try building, using Clang, a simple C program linking it with libatomic (the code doesn't actually have to use any symbols from the lib) and a simple C++ program that includes the <atomic> header. When compiling the C++ program, use the -std=c++11 compiler flag. If the C++ program compiles successfully, then it is not necessary for the libatomic linking test to be successful.
Interestingly, the CMakeOutput.log file still did not report finding GCC 4.8.2 as a candidate GCC installation, but the configuration/build worked well past the error.
Hopefully this helps. Please let us know if you run into something else.
CheckAtomic.cmake seems to be part of LLVM. I found a file at Github and it tries to find '__atomic_fetch_add_4' from libatomic
check_library_exists(atomic __atomic_fetch_add_4 "" HAVE_LIBATOMIC)
This fails for you. Check CMakeFiles/CMakeError.log to get more details why this test failed. Or try this line in a new project.

Using Scons to build mongo-nonx86 on an arm based Synology NAS

I have a Synology DS212j NAS (cpu Feroceon 88FR131 rev 1 (v5l)) with the optware ipkg installed. I am trying to build mongo-nonx86 on it.
"scons all" gives me the following messages:
scons: Reading SConscript files ...
scons version: 2.0.1
python version: 2 5 6 'final' 0
Checking whether the C++ compiler worksyes
Checking for C library stdc++... no
can't find stdc++ library which is needed
I have the stdc++ library installed, I also have ssl installed. My underlying question is how can I get scons to tell me more about what is really missing, where it is looking, how it is looking etc. I have so far found no options which generate any more useful diagnostic output?
Obviously a ready-made solution for getting mongodb working on this great little box would be even more welcome :-)
Well even if you do have it installed, it doesn't seem to think so, here is what I would try to do, install libssl-dev, then try to install the dev package for libstdc++, which is: libstdc++-dev.
Then see if you can compile it.

How to install cocos2dx on a mac?

I am following this tutorial to install cocos2d on a mac with eclipse.

I get as far as installing the ndk and I get the following error below when I try and execute ndk-build. I have set my paths correctly so im not sure why this is happening. Can anyone help me? Thanks
