I am trying to use mupdf in android application.I am using windows 7 and cygwin terminal.I used make but it gave error and
make NOX11=yes
execute successfully.
then i used ndk-build and it gives this error.

please help me.I am new to android ndk.
Thank you.
This seems like a known issue. Try adding the line:
NDK_TOOLCHAIN_VERSION=4.4.3
to the file ..\android\jin\Application.mk. That will at least get rid of this particular error.
EDIT: Look here http://code.google.com/p/android/issues/detail?id=35393 for more information
UPDATE:
mupdf world is a murky one. Even the version of NDK vis-a-vis the version of mupdf (http://mupdf.com/download/archive/) you use will determine what sort of errors or warnings you get. From my experience, mupdf-0.9 (+mupdf-thirdparty-2011-02-24.zip) behaves well with android-ndk-r6b, while mupdf-1.1 (+mupdf-thirdparty-2012-08-14.zip) will behave just fine with android-ndk-r8b.

I'm trying to get rust working on android. However, when I try to cross-compile to android I get the following linking error:
$ cargo build --target=arm-linux-androideabi
Compiling <project> v0.1.0 (<project>)
error: linking with `/opt/android-sdk/ndk/23.0.7599858/toolchains/llvm/prebuilt/linux-x86_64/bin/armv7a-linux-androideabi31-clang` failed: exit status: 1
(very long toolchain command from cargo)
ld: error: unable to find library -lgcc
clang-12: error: linker command failed with exit code 1 (use -v to see invocation)
I have installed the ndk and changed the linker in .cargo/config to the android clang linker. I also tried the standalone toolchains with the same result. The guide I used was the following: https://mozilla.github.io/firefox-browser-architecture/experiments/2017-09-21-rust-on-android.html
Cross-compilation does work when using crate-type = ["rlib"] instead of crate-type = ["cdylib"], but I need an .so file not an .rlib file.
In case it's relevant, i'm using Manjaro Linux.
UPDATE:
I found the following pull request: https://github.com/rust-lang/rust/pull/85806 After switching to ndk22 it worked. I havn't tried if the pull request fixes the issue (probably does).
Without switching to an older NDK version, I found using the workaround provided by ssrlive to work for me. Here's their comment:

This is of course extremely brittle and not the "right" solution, but the workaround works fine as of 2022-10-12 with ndk version 25.1.8937393.
while I am building glibc library using yocto project it is giving
error: missing attribute ((constructor)) support??
after adding the coverage flags:
TARGET_CFLAGS += "-fprofile-arcs -ftest-coverage"
TARGET_LDFLAGS += "-lgcov -fprofile-arcs -ftest-coverage"
still, I am getting an error for glibc.
Please find the link of config log file : https://drive.google.com/file/d/14tiQJ8JIFE_tDWt3H9tS8zBBQROcZDNa/view
It is not working even after adding the following line in conf/local.conf :
EXTRA_OECONF = "libc_cv_ctors_header=yes"
Even i tried this
EXTRA_OECONF_append = "libc_cv_ctors_header=yes"
please find the config log file generated during compilation : https://drive.google.com/open?id=1kxTu8pt7h_9ty55OywP9Ilmmp04T61Rr
So, How to resolve this error?

You are trying to build glibc with -fprofile-arcs -ftest-coverage in CFLAGS. That will not work. The errors you see are a result of these incorrect compiler flags.
A profiling glibc requires fairly substantial changes throughout the library and needs to be created by building with --enable-profile (which is not the default).
I had this error while I tried to enable coverage on a C project using a C++ test harness (CppUTest). Build system was handled by CMake.
Compilers and gcov were aligned on the same version (gcc --version, g++ --version and gcov --version gave the same version) but it seems that my build system was generated with a gcc 5 (resulting to an additional included directory by the linker: usr/lib/gcc/x86_64-linux-gnu/5). I clean the build tree and generated it again thanks to CMake which fixed the error.
I am sorry if the question is primitive, but I can't figure the problem. I want to read nifti image in C++ using ITK libraries. I have used the code on Github: https://gist.github.com/rafamanzo/a3c258f4f74e898e9418. It is very simple code to read an image. Then I configured ITK into my project using CMake. The following is my CMakeLists.txt file:
cmake_minimum_required(VERSION 2.8)
project(MyProject)
set(CMAKE_INSTALL_PREFIX "/home/itk")
set(ITK_DIR "/home/itk/InsightToolkit-4.13.0/bin/")
set(VTK_DIR "/home/vtk/VTK-8.1.0/bin/")
find_package(ITK REQUIRED)
find_package(VTK REQUIRED)
if (ITKVtkGlue_LOADED)
find_package(VTK REQUIRED)
include(${VTK_USE_FILE})
else()
find_package(ItkVtkGlue REQUIRED)
include(${ItkVtkGlue_USE_FILE})
set(Glue ItkVtkGlue)
endif()
include(${ITK_USE_FILE})
include(${VTK_USE_FILE})
add_executable(MyProject mainFile.cxx)
target_link_libraries(MyProject ${ITK_LIBRARIES})
"cmake .." is ran successfully.
But "make all" gives me an error:
make[2]: *** No rule to make target '/home/vtk/VTK-8.1.0/bin/lib/libvtkRenderingOpenGL2.so', needed by 'MyProject'. Stop.
CMakeFiles/Makefile2:67: recipe for target 'CMakeFiles/MyProject.dir/all' failed
make[1]: *** [CMakeFiles/MyProject.dir/all] Error 2
Makefile:83: recipe for target 'all' failed
And surprisingly, when I build the project from Eclipse, I got another error:
./bin/CMakeFiles/feature_tests.o: In function `main':
/home/MyProject/Debug/../bin/CMakeFiles/feature_tests.c:34: multiple definition of `main'

collect2: error: ld returned 1 exit status
make: *** [MyProject] Error 1
I am pretty sure that configuring ITK is easy, especially I have done it before, but to use ImageFileReader only. Any help is much appreciated. Thank you.
Just to read an image you don't need VTKGlue part of ITK nor VTK itself. And the reported problem comes from VTK. If you want to keep VTK (to be used for something else?), you should fix it. Maybe you need to set VTK_RENDERING_BACKEND to OpenGL2 or something similar. Try building some VTK examples using your VTK to see if those examples build and run. That might point you more precisely to the problem.
I am trying to compile a .f Fortran code with Eclipse. I have tried both of the below methods from the Eclipse help site:
Starting a Project with an Auto-Generated Makefile
Starting a Project with a Hand-Written Makefile
However, Eclipse gives multiple different errors... Here are some of the errors:
DIMENSION DDDJ(0:IG,-1:JG)
1
Error: Non-numeric character in statement label at (1)
../Main1.f:16.5:
DIMENSION DDDJ(0:IG,-1:JG)

Fatal Error: Error count reached limit of 25.
make: *** [Main1.o] Error 1
14:51:55 Build Finished (took 1s.244ms)
I have compiled the code in the terminal using Gfortran simply and i have obtained the executable file an obtained the results. But Eclipse did not work for me at all.
I want to debug my code. it is 1236 raws. Can someone help me with Eclipse or any other suggestion?
It is related with the form of Fortran file. I was copying the code into a new Fortran source file. I decided to import the file that I have into the project.
I am in the middle of integrating UA into my Phonegap/iOS application using the UA Phonegap plugin https://github.com/urbanairship/phonegap-ua-push.
Unfortunately, I can not get it to work. Even the sample project fails to build. The problem is a duplicate symbol during linking. Please note: i did not include any additional headers, libs, etc. I am just trying to build the iOS sample project.
The clashing symbol seems to be rooted in the ASI* (ASIHttpRequest, ASIAuthenticationDialog, etc) library, which has been integrated into UA. Surprisingly, the clashing happens between both UA libs (libUAirship-1.3.2.a and libUAirshipPush-1.3.2.a).
Linker output: ld: duplicate symbol _OBJC_METACLASS_$_UA_ASIAutorotatingViewController in /Users/b/Downloads/urbanairship-phonegap-ua-push-9b7a89b/ios-sample/Airship/libUAirshipPush-1.3.2.a(UA_ASIAuthenticationDialog.o) and /Users/b/Downloads/urbanairship-phonegap-ua-push-9b7a89b/ios-sample/Airship/libUAirship-1.3.2.a(UA_ASIAuthenticationDialog.o) for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
How can this happen?
This issue appeared for me when I add the flag "-ObjC" in my target settings at "Other Linker Flags".
Check it, i need the flag for an another library but if it's not your case...
