I want to use gcc in docker/singularity image to compile a program. Using local gcc, I use gcc tc.c -I PATH_TO_LIB without any error. To use the gcc in the image, I use the following command line.
singularity exec gcc_5.1.0.sif gcc tc.c -I PATH_TO_LIB
But the problem is that gcc cannot find the .h file in the library path. It returns the following error.
fatal error: csmith.h: No such file or directory
#include "csmith.h"

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++'
Disclamer: using -nostdcincl isn't possible because it excludes needed system libraries. Here instead the problem seems to be that tthe compiler ignores my -I directives
I have installed a library (OpenCV) in ~/local on a remote machine, since I don't have sudo access there. Notice that an older version of the same library is installed in /usr/local.
I'm trying to compile this code:
g++ -DCC_DISABLE_CUDA -I/home/spm1428/CloudCache -I/home/spm1428/local/include/opencv -I/home/spm1428/local/include/opencv2 -I/usr/include/boost -I/home/spm1428/vlfeat -O3 -g -Wall -c -fopenmp -std=c++11 -c -o Descriptor.o ../Descriptors/Descriptor.cpp
However, the returned error is:
In file included from /usr/local/include/opencv2/opencv.hpp:77:0,
from /home/spm1428/CloudCache/Utilities/Utility.hpp:11,
from ../Descriptors/Descriptor.cpp:17:

I think that this happens because there is another version installed. How can I solve this?
I think this error happens for the same reason (the old version doesn't have cv::xfeatures2d::SURF).
I have read the related questions but I cannot solve my problem.
I'm trying to compile a OpenCV C++ code on raspberry pi.
OpenCV requires cv.h to be included. When I try to compile I get:
"fatal error: cv.h: No such file or directory."
I have tried these:
g++ -c -Ihome/pi/OpenCV-2.3.1/include/opencv file.cpp
g++ -c -Ipi/OpenCV-2.3.1/include/opencv file.cpp
g++ -c -IOpenCV-2.3.1/include/opencv file.cpp
Do any of you have any ideas?
This is a general question and not related only to OpenCV.
For the general problem of including any header file
1. Try to see if the file is really at the included directory or no
2. Try to look for it in the folder
When I try to build Assimp by running build_ios.sh, it tells me:
CMake Error: your C compiler: "/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/llvm-gcc" was not found. Please set CMAKE_C_COMPILER to a valid compiler path or name.
CMake Error: your CXX compiler: "/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/llvm-g++" was not found. Please set CMAKE_CXX_COMPILER to a valid compiler path or name.
What I need the path to be is:
/Applications/XCode.app/Contents/Developer/Platforms/...
I've tried changing DEVROOT in build_ios.sh and IPHONE_xxxx_TOOLCHAIN.cmake, because that's what CMAKE_C_COMPILER etc seem to get generated from, but it still gives me the same errors.
Option 1:
You can set CMake variables at command line like this:
cmake -D CMAKE_C_COMPILER="/path/to/your/c/compiler/executable" -D CMAKE_CXX_COMPILER "/path/to/your/cpp/compiler/executable" /path/to/directory/containing/CMakeLists.txt
See this to learn how to create a CMake cache entry.
Option 2:
In your shell script build_ios.sh you can set environment variables CC and CXX to point to your C and C++ compiler executable respectively, example:
export CC=/path/to/your/c/compiler/executable
export CXX=/path/to/your/cpp/compiler/executable
cmake /path/to/directory/containing/CMakeLists.txt
Option 3:
Edit the CMakeLists.txt file of "Assimp": Add these lines at the top (must be added before you use project() or enable_language() command)
set(CMAKE_C_COMPILER "/path/to/your/c/compiler/executable")
set(CMAKE_CXX_COMPILER "/path/to/your/cpp/compiler/executable")
See this to learn how to use set command in CMake. Also this is a useful resource for understanding use of some of the common CMake variables.
Here is the relevant entry from the official FAQ: https://gitlab.kitware.com/cmake/community/wikis/FAQ#how-do-i-use-a-different-compiler
The cc and cxx is located inside /Applications/Xcode.app. This should find the right paths
export CXX=`xcrun -find c++`
export CC=`xcrun -find cc`
SOLUTIONS
Sometimes the project is created before installing g++. So install g++ first and then recreate your project. This worked for me.
Paste the following line in CMakeCache.txt:
CMAKE_CXX_COMPILER:FILEPATH=/usr/bin/c++
Note the path to g++ depends on OS. I have used my fedora path obtained using which g++
Where can I find yylloc? I have included libfl.a (-lfl) in gcc command line, added GnuWin32/bin and GnuWin32/lib directories to system variable LIB, searched through all files in GnuWin32 - neither I nor gcc can find it.
It's Bison variable, it cannot be used without Bison-generated .c file.
