I am trying to compile Opencv on Ubuntu 18.04. I installed many dependencies packages but when I run make I get the error:
grfmt_jpeg2000.cpp:59:10: fatal error: jasper/jasper.h: No such file or directory
#include <jasper/jasper.h>
^~~~~~~~~~~~~~~~~
compilation terminated.
I had already jasper installed and installed libjasperreports-java. However the file jasper.h cannot still be found in my system. Is there any library I can install with apt install to get that file? Or am I missing any other library?
EDIT 1
I tried also downloading the opencv_contrib to install extra moduels of openCV but first of all jaspar is not present and secondly setting the build with
cmake -D CMAKE_INSTALL_PREFIX=./ -D CMAKE_BUILD_TYPE=Debug -D OPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules ../openCV
returns the error:
Make Error at cmake/OpenCVModule.cmake:352 (message):
Duplicated modules NAMES has been found
while CMakeError.log contains many errors of the type:
Build output check failed:
Regex: 'command line option .* is valid for .* but not for C\+\+'
Output line: 'cc1plus: warning: command line option ‘-Wstrict-prototypes’ is valid for C/ObjC but not for C++'
I'm running through some various programming/debugging tutorials and uses the "otool" command in terminal. An example is to check for shared libraries. The error is always one of two. I'm running it from the directory the file is located. Typing in just otool give the list of otool "-x" switches. I've gone down the list of switches on multiple files and directories and get the same errors.
What am I missing?
$ otool -L DemoApp
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/otool: can't open file: DemoApp (No such file or directory)
or
$ otool -L DemoApp.app
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/otool: can't map file: DemoApp.app (Invalid argument)
you need to point to a final executable file. DemoApp.app is just a directory. Try otool -L ~/Applications/DemoApp.app/Contents/MacOS/DemoApp
I'm cross-compiling the Dart runtime using the instruction here.
I've installed all the dependencies as specified. I've also cloned the git repository with the necessary tool chain.
I'm running the runtime compilation with this command:
./tools/build.py -m release -a arm --toolchain=../tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf runtime
The compilation starts with no problem then it stops with this error:

BUILD FAILED
Am I missing any dependency or package?
I hit the same problem. On my ubuntu 14.04 system /usr/include/asm didn't exist. It was called asm-generic instead. I sym-linked it and the build was able to continue.
cd /usr/include
sudo ln -s asm-generic/ asm
The build was able to continue after that.
This is probably because you're trying to build an application without some of the include paths correctly set, for example using a 32-bit gcc on a 64-bit platform.
To resolve:
sudo apt-get install gcc-multilib
I'm not sure why this happens, but sometimes /usr/include/asm gets deleted. My teammates who looked at their Ubuntu x86-64 workstations found that the asm symlink was:
0 lrwxrwxrwx 1 root root 20 May 22 2013 /usr/include/asm -> x86_64-linux-gnu/asm
And the command to recreate it is:
$ cd /usr/include
$ sudo ln -s x86_64-linux-gnu/asm asm
The files in /usr/include/asm-generic are sometimes, but not always, equivalent to the files in the x86-64 specific directory; so it's difficult to recommend symlinking it as a workaround.
After reading article found at https://www.dartlang.org/articles/web-ui/tools.html, I tried to compile my application by following it.
My application stored in web/app.html can be successfully compiled to Javascript under DartEditor by using "Run as Javascript" command.
When I try to use following command lines to perform a compilation for deploying in production, I encounter an issue on uncopied package part file.
$ dart --package-root=packages/ packages/web_ui/dwc.dart --out /tmp/dart/ --no-rewrite-urls web/app.html
$ ls lib/app/
model_browser.dart model_server.dart
$ ls lib/app/src/model/
model_browser.dart model_server.dart model_shared.dart
$ cd /tmp/dart
$ dart2js -v app.html_bootstrap.dart --package-root=packages/ -oapp.html_bootstrap.dart.js
...
info: scanning library file:///private/tmp/dart/_from_packages/bm/model_browser.dart
_from_packages/app/model_browser.dart:12:1: Error: Cannot read "_from_packages/app/src/model/model_shared.dart" (OS Error: No such file or directory, errno = 2).
part 'src/model/model_shared.dart';
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
info: Error: compiler cancelled: Error: Cannot read "_from_packages/app/src/model/model_shared.dart" (OS Error: No such file or directory, errno = 2).
...
$ ls _from_packages/app/
model_browser.dart model_browser.dart.map
$ ls _from_packages/app/src/model/
model_browser.dart model_browser.dart.map
In fact, "model_shared.dart" file isn't copied into /tmp/dart/_from_packages/app/src/model/model_shared.dart.
The content of model_browser.dart is following
library model;
import 'dart:json' as json;
import 'package:bm/i18n.dart' as i18n;
import 'package:logging/logging.dart';
import 'package:web_ui/web_ui.dart';
part 'src/model/model_shared.dart';
part 'src/model/model_browser.dart';
DartEditor can launch my application as Javascript. What is the right command line for launching dart2js in order to take into account the "part" statements of my "model" library ?
The issue is linked to "--no-rewrite-urls" option and the absolute path in --out option.
If I remove the "--no-rewrite-urls" option and put a relative path in --out option, the dart2js compilation is successfully done.
After upgrading to Xcode 4.3.2. I'm getting a metric ton of build errors.
A whole line of them are error code 255
gcc-4.2: error trying to exec '/usr/bin/arm-apple-darwin11-gcc-4.2.1': execvp: No such file or directory
Command /usr/bin/gcc-4.2 failed with exit code 255
I noticed that there is no /usr/bin/arm-apple-darwin11-gcc-4.2.1 file on my machine. Could this be the source of the problem?
What's the output of this command?
$ printenv | grep "CC="
It might be honoring your C Compiler (CC) selection. I was getting similar errors (through cocoapods) and doing an
$ export CC=
fixed it for me.
