I am trying to get g++ to compile a program that uses Magick++, however despite installing the libraries, I get the below error when compiling the program with g++ WallFade.cpp `Magick++-config --cxxflags --cppflags --ldflags --libs` -o WallFade:
fatal error: Magick++.h: No such file or directory
4 | #include <Magick++.h>
| ^~~~~~~~~~~~
compilation terminated.
When I set an absolute path to the header file by replacing #include <Magick++.h> with #include "/usr/local/include/ImageMagick-7/Magick++.h" I then get the following error:
/usr/local/bin/Magick++-config: line 47: --cflags: command not found
/usr/local/bin/Magick++-config: line 50: --cflags: command not found
/usr/local/bin/Magick++-config: line 53: --libs: command not found
/usr/local/bin/Magick++-config: line 56: --libs: command not found

10 | #include <Magick++/Include.h>
| ^~~~~~~~~~~~~~~~~~~~

I'm assuming I need to run some command to link the header files to g++, but I'm not sure what that command would be (currently running Arch Linux).
Install following package libmagick++-dev
packman -S libmagick++-dev
I think this is the way to install it on Arch.

I have a project (here) that works both on Linux and intel MacOS, but in my Mac m1 it doesn't. Whenever I try to compile it, I get the following errors (ops.: I'm using vscode m1 native):

Before hand I ran these three commands and they worked successfully, no errors nor warnings at all, so I assumed it was all working fine.
brew install glfw
brew install sdl2
brew install sdl2_mixer
Anyone has any ideas?
My issue was partially solved. There were two problems, GLFWand SDL2.
GLFW
The fix was the same proposed in this thread; in a nutshell it consists in:
$ nano ~/.zshrc
> export CPATH=/opt/homebrew/include
> export LIBRARY_PATH=/opt/homebrew/lib
This will tell the compiler to look for things in opt/homebrew, which is where homebrew for m1 installs the packages, instead of usr/local.
SDL2
I downloaded the two .dmg files from the websites below
https://www.libsdl.org/download-2.0.php
https://www.libsdl.org/projects/SDL_mixer/
Then I went to the downloads and copied the .framework directory from both downloads and pasted into /Library/Frameworks.
This solved those errors from before, that the system could not find the includes, but a new error showed up: symbols not found for architecture arm64. I decided to quit trying and just removed the sound out of my game (it was a college assignment, no biggie in taking features out).
On MacOS Monterey 12.6 I fixed the issue by installing xcode, then installed with homebrew:
glew
glfw3
xquartz
brew install glew glfw3
brew install --cask xquartz
Then I pointed to the X11 folders and sample OpenGL program compiled.
The github source code was taken from: https://github.com/zamirmf/OpenGLOnMac
For example:
clang -o testopengl main.cpp \
-L/opt/X11/lib -L/opt/homebrew/lib \
-I/opt/X11/include -I/opt/homebrew/include \
-lglfw -framework OpenGL
I am trying to compile a cpp using with the following command:
g++ -IC:\Users\XXX\libcurl-7.56.0\libcurl-7.56.0\include\curl -LC:\Users\XXX\libcurl-7.56.0\libcurl-7.56.0\lib program.cpp
this program has a header file which uses libcurl. the curl library is at -
C:\Users\XXX\libcurl-7.56.0\libcurl-7.56.0\include\curl\curl.h
gcc gives the following error even though curl.h is in the path -I
mylibrary.h:26:10: fatal error: curl/curl.h: No such file or directory
#include <curl/curl.h>
what am I doing wrong?
The error message means the file curl/curl.h could not be found in the search path specified by -I. You updated the question with the path to the file so the command should be:
g++ -IC:\Users\XXX\libcurl-7.56.0\libcurl-7.56.0\include -LC:\Users\XXX\libcurl-7.56.0\libcurl-7.56.0\lib program.cpp
Also, can you please try using \ instead of / as path separator in your mylibrary.h file:
#include <curl\curl.h>
I am using MacOS 10.15. Since the clang shipped with MacOS does not include clang-format. I installed another pre-built clang binary from here. I have added the binary file path to my PATH variable.
export PATH="$HOME/tools/clang+llvm-10.0.0-x86_64-apple-darwin/bin:$PATH"
I tried to compile a simple program:
#include <iostream>
int main(int argc, char *argv[]) {
std::cout << "Hello world!\n";
return 0;
}
using the following command:
clang++ hello.cpp -o hello
I got the following error:
In file included from hello.cpp:1:

#include_next <wchar.h>
^~~~~~~~~

I found that wchar.h bundled with this pre-built package is in the following directory:
/Users/jdhao/tools/clang+llvm-10.0.0-x86_64-apple-darwin/include/c++/v1/
So I added the -I flag:
clang++ -I /Users/jdhao/tools/clang+llvm-10.0.0-x86_64-apple-darwin/include/c++/v1 hello.cpp -o hello
The error still persists.
If I use clang++ shipped with MacOS, I have no problem compiling the source code:
# the following works without any error
/usr/bin/clang++ hello.cpp -o hello
I have seen post here, here, and here, but the solutions do not apply.
You got clang-format improperly. Reset the system to the state before you installed another pre-built clang binary. Then use Homebrew to install clang-format
brew install clang-format
clang+llvm-10.0.0-x86_64-apple-darwin is not suitable to your Mac. It depends on system frameworks that are not available, so you get the error finding wchar.h in a system framework. When you install clang+llvm-10.0.0-x86_64-apple-darwin you ignore framework dependencies. Homebrew will care about dependencies.
I have a 16inch MacBook pro with latest updates (macOS Catalina 10.15.2 (19C57)), the latest version of XCode and Command line tools for macOS (the tools being installed in the usual path /Library/Developer/CommandLineTools/).. Not sure if this is relevant to my issue or not, but I also have the latest version of JetBrains’s CLion installed on my machine (running without issues).
Here is the problem: When trying to build a project with cmake, the build FAILS, giving me this error message:

and this is probably related to my C++ compiler not having the correct path to the include files. To see what the issue could be, I’ve made a simple C++ file and I tried to compile it.
main.cpp
#include <iostream>
#include <string>
#include <cmath>
#include <vector>
int main()
{
std::string name = "NAMEX";
std::cout << name;
}
First, I tried with the usual “g++” and it worked just fine:
basavyr#Roberts-MacBook-Pro stringTestCLANG % g++ main.cpp
basavyr#Roberts-MacBook-Pro stringTestCLANG % ./a.out
NAMEX% basavyr#Roberts-MacBook-Pro stringTestCLANG %
Then, I tried with /Applications/Xcode.app/Contents/Developer/usr/bin/g++ main.cpp and it worked just fine.
Checking the version of “g++” on my machine gives me this:
g++ -v
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/4.2.1
Apple clang version 11.0.0 (clang-1100.0.33.17)
Target: x86_64-apple-darwin19.2.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
This is interesting, because I was expecting that the default compiler is installed in /usr/bin/ instead. Going into that “InstalledDir” folder I saw that there is no “g++” binary, but only “clang++” and “c++”, so I tried to compile with both and it turns out that both compilers are giving the same error as the one in the project that I trying to build:

Since I also have Command Line Tools installed, I tried to compile with both “g++” and “clang++” from /Library/Developer/CommandLineTools/usr/bin/ and the first one compiles successfully, while the second one throws the same error with regards to the string header file.

So, I assume that when I build that project with cmake, it is using one of these compilers (from the XCodeDefault.xctoolchain folder) and it has issues with the string header.
Q1: How can I solve this issue? Q2: And also, why does my “g++” installation directory points to this XCodeDefault.xctoolchain instead of “/usr/bin/’ or “/Applications/Xcode.app/Contents/Developer/usr/bin/”. Is there a way to change that in macOS?
Thank you in advance
I was using Spidermonkey 24 earlier but then moved to version 38 yesterday. But the problem is I'm unable to compile any program using this version. I tried compiling the sample code that came within but it gives the following error:
sudo g++ -I /home/pi/mozjs-38.0.0/js/src/build_OPT.OBJ/dist/include/ -L /home/pi/mozjs-38.0.0/js/src/build_OPT.OBJ/dist/lib/ sample.cpp -o sample -lmozjs-38 -lz -lpthread -ldl
In file included from sample.cpp:1:0:
sample.h:6:21: fatal error: jscntxt.h: No such file or directory
#include "jscntxt.h"
^
compilation terminated.
Note: The path to that header is already specified in the command.
I was successfully compiling the program using the same command with spidermonkey24.
Thanks!
