I used module at this link :
https://github.com/TermiT/ZipFile
But When we run this file (build.py) fallowing the I take error
The following build commands failed:
CompileC build/ZipFile.build/Release-iphoneos/zipfile.build/Objects-normal/armv7/ZipfileModule.o Classes/ZipfileModule.m normal armv7 objective-c com.apple.compilers.llvm.clang.1_0.compiler
thanks.
I had the same problem, and while searching it turned out that we're missing the GCC compiler, here's a link for what I've found, https://github.com/TermiT/ZipFile/issues/15 , and it also have a link to download the GCC compiler.

I'm trying to convert a java library to objective-c using j2objc and include the generated objc files into my XCode project. I managed to generate the objc files, but XCode gives me the following error: https://i.stack.imgur.com/QX3zF.png
I used lipo -info on a .o file and I get this "architecture: x86_64". Does it mean those objc files are not meant to run on arm64 architectures and if so, how can I solve this ? Are there any flags I could use to generate the files for arm64 ?
A previous error I had was "ARC forbids explicit message" and I solved this by adding a compiler flag -fno-objc-arc to all the compile sources related to this error. Is this solution safe ?
To compile for arm64, the -arch arm64 and -isysroot IPHONE_SDK_DIRECTORY flags are needed. To find the IPHONE_SDK_DIRECTORY on your system, run xcrun -sdk iphoneos --show-sdk-path.
There's nothing J2ObjC-specific about this, they are normal iOS flags you'll find in you look at the log of a successful compile of an Objective C file in Xcode and click its right button to expand and show all the flags used.
J2ObjC by default does not generate ARC code, so the -fno-objc-arc flag is okay. If you would prefer ARC, run j2objc with its -use-arc flag. Don't compile those generated files with -fno-objc-arc, however, as objects won't be released when your app is finished with them.
During building a c++ source code (configured with cmake gui) with mingw under MSYS gives following error while trying to "Linking C shared library":
Unrecognized option "--enable-new-dtags"
How can i solve this issue?
Likely --enable-new-dtags is supported only on ELF targets. For example there's a patch for Python3 distutils which sets this flag conditionally on the target platform: https://github.com/Alexpux/MINGW-packages/blob/master/mingw-w64-python3/0260-MINGW-compiler-enable-new-dtags.patch . You should make sure that this flag isn't specified explicitly somewhere in your project.
I'm trying to include a static library in module.xcconfig. But the documentation isn't helpful, and all the discussion I can find does not give a solution.
Where do I put the static library, and how do I include it using OTHER_LDFLAGS? I've tried:
OTHER_LDFLAGS=$(inherited) mylib.a
OTHER_LDFLAGS=$(inherited) -lmylib
mylib.a is in the root of the module at the same level as module.xcconfig, because someone on the Appcelerator site said to do that.
build.py runs fine for the module, but once I try to build my project, I get:
The following build commands failed:
[ERROR] Ld build/Debug-iphonesimulator/ ... normal i386
[ERROR] (1 failure)
What am I doing wrong? Thanks.
add this line to the module.xcconfig
OTHER_LDFLAGS=$(inherited) -framework GameKit
where GameKit is your missing framework that is used in your library.
And add your library direct to your xCode project via drag-n-drop.
you might need to include the fill path to the library, also it should be included in the build settings of the xcode project
I am trying to compile a project for iOS 6 in XCode, and I am using the following headers, which include the functionality I need:
#include "cdjpeg.h" /* Common decls for cjpeg/djpeg applications */
#include "transupp.h" /* Support routines for jpegtran */
Those are straight out of jpegtran utility sources. I have installed the jpeg library before, and there is libjpeg.a in my /usr/local/lib/.
However when I try to compile, I am getting an error "Undefined symbols for architecture i386" or "Undefined symbols for architecture armv7", depending on whether target is an iPhone simulator or not.
Here are the keywords it can't find symbols for:
"_jpeg_stdio_src"
"_jpeg_finish_compress"
"_jcopy_markers_execute"
"_jpeg_copy_critical_parameters"
"_jtransform_adjust_parameters"
"_jpeg_destroy_compress"
"_jtransform_execute_transform"
"_jpeg_finish_decompress"
"_jpeg_read_header"
"_jtransform_request_workspace"
"_jpeg_write_coefficients"
"_jpeg_read_coefficients"
"_jpeg_destroy_decompress"
"_jpeg_stdio_dest"
"_jcopy_markers_setup"
I have encountered the missing symbol errors before, and always ended giving up on using 3rd party libraries, but in that particular case there's no way around.
What am I doing wrong here?
EDIT: I have added libjpeg.a to project settings and it did go further, but stopped now at:
Apple clang version 4.1 (tags/Apple/clang-421.11.66) (based on LLVM 3.1svn)
Target: i386-apple-darwin12.2.0
Thread model: posix
"lots-of-debug-paths"
ld: library not found for -ljpeg
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I recently needed libjpeg for iOS too (as a dependency of another third party library)
I ended up simply using the libjpeg-turbo, which comes with a precompiled fat binary
Architectures in the fat file: libjpeg.dylib are: i386 x86_64 armv6 armv7 armv7s arm64
I dunno how you compiled it. But you need to change the make install in order to compile it in i386 and armv7. I'm pretty sure you just run the make, so it compiled it for you mac, which is certainly a x84_64 arch, and this is certainly not what you want
You can check with
lipo -info /usr/local/lib/libjpeg.a // if libjpeg.a is at this path
or
file /usr/local/lib/libjpeg.a
My XCode version is 4.2 for iOS 5.0. I choose "LLVM GCC 4.2" as the compiler. When I compile my project, it show me the following error:
ld: warning: directory not found for option '-L/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk/usr/lib/gcc/arm-apple-darwin10/4.0.1'
ld: warning: directory not found for option '-L/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk/usr/lib/gcc/arm-apple-darwin10/4.2.1'
ld: library not found for -lz.1.2.3
Command /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/llvm-g++-4.2 failed with exit code 1
Please help me figure out why this is happening and how to fix it.
The libz.1.2.3 library does not exist anymore (or at least is not included in the SDK). In your project settings, link with a newer version of the library like libz.1.2.5.
