Using OSX and vim...
Downloaded SDL2 from the website, then moved the SDL2.framework into /Library/Frameworks/
Using tutorial code, and Makefile... SDL.h is not found.
Makefile: g++sdl-config --cflags --libssdltest.cpp -o sdltest
I've read numerous things about pointing the compiler to the framework, but everything I've tried doesn't seem to work, and I thought /Library/Frameworks/ was the default area for the compiler to look
Got it to work.
Getting this to work took multiple tries, but the root of the issue for each try was that most of the Tutorials I was looking at were for SDL1.2 when I was using SDL2.
This changed flags in the make file, directories to search in and other things. Interestingly, I could never get the compiler to see SDL.h when it was in the /Library/Frameworks/ directory. However using Macports to install SDL2 allowed me to point the compiler to where Macports installed SDL2 header files - /opt/local/include/SDL2
That seems to have done it for me
Thank you for your question, because I was having similar difficulties! There seems to be a dearth of detailed and helpful tutorials on how to install SDL2 using Macports.
I got it working! Here are the steps:
Visit this link to find the Macports package appropriate for your version of Mac OS X. Install the version you need, and once that is done, proceed to step 2.
https://www.macports.org/install.php
After installation is done, visit this link to find the SDL2 port.
https://www.macports.org/ports.php?by=name&substr=libsdl
The one I needed was the third from the top, called libsdl2. I will be providing the name for you so feel free to visit the link simply for your own edification.
Open the Terminal, and type sudo port install libsdl2. If all goes to plan, you should see it installing and updating. Once it is complete, you should have a functional installation of the SDL2 Header files, (ending in .h), Static Library files (ending in .a) and Dynamic Library files (which contain dylib). You may have to do some poking around in Finder to locate where it installed.
The advantage of this workaround is the ability to use SDL with other IDE's besides Xcode, Eclipse for instance. Whereas Xcode requires you to assign a path of /Library/Frameworks, this technique should allow you to use the IDE of your choosing.
The final step is going into your IDE and assigning the build paths to these newly installed and compiled SDL files. For instance, the paths for mine are /opt/local/include and /opt/local/lib. Be mindful of the fact that your path may differ from these, but these examples should give you an idea of where to look.
Hopefully this is helpful for somebody!

Hi I am having problems with trying to get sfml going with netbeans. Here is a short video of what I have done. video
After listening to HEKTO I now downloaded the MSYS. I removed the static libraries and get this error now:
The application failed with exit code -1073741515 (0xc0000135).
This could indicate that no required .dll was found in the PATH.
Please try to start the following command from the command shell (cmd.exe).
This may give some additional information.
C:\Users\david\Documents\NetBeansProjects\tester\dist\Debug\MinGW_1-Windows\tester.exe
RUN FAILED (exit value -1,073,741,515, total time: 58ms)
After adding system path.. heres new img:

The SFML developers recommend the exact match between your MinGW version and your SFML version - please see this page, especially these three lines:
The compiler versions have to match 100%!
Here are links to the specific MinGW compiler versions used to build the provided packages:
TDM 5.1.0 (32-bit), MinGW Builds 7.3.0 (32-bit), MinGW Builds 7.3.0 (64-bit)
Your MinGW compiler is 8.2.0 - it doesn't match. So you'll need to download the MinGW using links from this page and install it manually.
Also you try to link with static libraries (with suffix _s). In this case you have to add other libraries to the linker setup - please see here. If to use dynamic libraries then you won't need any additional libraries, however the SFML directory with its DLLs will need to be added to the system path.
UPDATE. Your question has been rewritten many times, so my answer has become irrelevant - this is not good, the question can be updated to improve it, but please not to rewrite it completely following additional information given to you in comments. References to videos and pictures aren't welcomed here also. Your question must be self-contained and potentially helpful for others, looking for help in similar situations.
That said I'll add two tips for future generations:
Don't use relative paths for include and lib directories in the NetBeans compiler and linker setup - use only absolute paths.
MinGW distributions, referenced on the SFML downloading page, don't contain the MSYS (small collection of Unix tools, which includes make.exe). You'll need to download and install the MSYS separately, for example using the MinGW installer with msys-base package only.
I am trying to install QuantLib on my Mac running OSX 10.11.6. Installed Boost 1.59 via MacPorts and then followed these instructions.
I used these additional environment variables
./configure --with-boost-include=/opt/local/include/ \
--with-boost-lib=/opt/local/lib/ --prefix=/opt/local/ \
CXXFLAGS='-O2 -stdlib=libstdc++ -mmacosx-version-min=10.6' \
LDFLAGS='-stdlib=libstdc++ -mmacosx-version-min=10.6'
and then make && sudo make install.
However when I run the Bermuda Swaption test it gave me the same error described here.
Little premise: I don't know anything about C++. I need QuantLib to work on Python. So I read carefully the answer by SmallChess and tried to solve it by myself. As I read in his answer
You can't just compile BermudanSwaption.cpp and hope everything would be fine. You have to compile the entire QuantLib library and link with the generated library files. Please google "compiling and linking C++" for more information.
By far, the easiest way to make it happen on Mac is to do it with Xcode. You will need to create a new Xcode project, and import the entire Quantlib project files into it. Next, you will need to create a main() function. Xcode does the compiling and linking for your automatically.
This is what I exactly did:
created a new project in Xcode (version 8.2.1)(file/new project/Command Line Tool/"HelloWorld"/Documents/create)
selected Targets, Build Phases and Link Binary With Library. Added libQuantLib.0.dylib
set libstdc++(GNUC++ standard library) as C++ Standard Library in Build Settings
Modified Header Search Paths to include: /opt/local/include/, and Library Search Paths to include: /opt/local/lib
C++ Language Dialect is set on Compiler Default.
Dragged the ql folder onto the left window of the Xcode
Now, I managed to copy a simple code which includes the library and even if there are many warnings, it runs. Still when I run on the Terminal the command for the Bermuda Swaption test I get the same error. What am I doing wrong?
Additional info (may or may not be useful): if I change the C++ Standard Library setting on Xcode to libc++, I get on Xcode the same error I get when i try the Bermuda Swaption test (ld: symbol(s) not found for architecture x86_64).
Any help would be very much appreciated
Regards

I am going off of LazyFoo's SDL2 tutorials for C++ using the MinGW g++ compiler (using console). I have followed his page here, step-for-step. I have finally come across this error after having downloaded his example.
I have seen plenty of people online struggle with SDL_Image, but I've not yet seen this and I haven't found any solution to it yet.
I've loaded the include and lib folders with the proper assets
I've copied all necessary .dll's to my compile destination
The example LazyFoo provides includes for SDL_Image and SDL itself
(this question my sound redundant, but I've yet to come across a solution that applies to console-compilation)
Based on the comments above, the answer seems to be:
You need to install the development libraries for SDL_image.
You can download them here: https://www.libsdl.org/projects/SDL_image/
(look under the heading "Development libraries").
You need to ensure the path where the libSDL2_image.a file resides is in the linker search path. One way of doing this is to add an appropriate -L parameter to the link command. You could also drop the file in the default library search path.
I've had this problem in linux. the solution is simple.
add to linker:
-lSDL2_image -g `sdl2-config --cflags --libs`
I had the same problem, and the solution was to include the SDL2main library in linker parameters.
For Dev-C++ IDE you can follow the instructions below:

I am currently learning C++ using Lynda.com tutorials, I am a complete beginner and am following the tutorials on how to set up Eclipse on my Mac.
When I initially run the version-test.cpp program provided, it runs fine with the expected output (GCC version 4.2.1)
The tutorial requires my Mac to be running GCC version 4.7.0 or above and it explains how to upgrade GCC. The tutorial instructs me to save the updated GCC files within my home directory within the folder hpc-gcc and then follows on to explain the method to set my PATHs to find this folder.
Now when I run the version-test.cpp program it fails with the following error
dyld: Library not loaded: /usr/local/lib/libmpc.3.dylib
Referenced from: /Users/gary/hpc-gcc/bin/../libexec/gcc/x86_64-apple-darwin13.1.0/4.9.0/cc1plus
Reason: image not found
So from this message I can see that the system cannot find the required files within /usr/local/lib.
I am able to copy the files from hpc-gcc/bin to /usr/local/lib and have the program compile and run correctly but I am hoping to find out why Eclipse cannot read the required files directly from ~/hpc-gcc/bin
I have spent the last 2 hours searching forums and search engines for the answer but I am no further forward. I realise I can simply have the GCC files within /usr/local/lib and it will work but I want to understand where I am going wrong.
Solved.
You need to go into the properties of the Working folder (if you are following the lynda.com program you will understand the working folder) and under C/C++ Build -> Environment menu (Where we added in the LIBRARY_PATH, PATH, AND CPATH variables) and add in DYLD_LIBRARY_PATH with a value of ${HOME}/hpc-gcc/lib.
Remember the C/C++ Build "menus" are for build and debug, so the project is not able to find the library for the building process.
And you will be good to go.
I recently tried to figure out how to use freeglut with NetBeans 7.
I Google'd a lot and I didn't find a suitable tutorial on how to bind the stuff I need into it.
Currently I have more problem then this:
First one is:
- freeglut 2.8 => in order to compile it I need MinGW and msys.
I have both installed but I can't "configure" or "make all" and "make install" freeglut.
I didn't find an easy-to-read how-to for that task.
Next one:
- once built, where to put what files into a specific folder?
Last one:
- Once put the files into corresponding folder, how to use finally freeglut under NetBeans 7 on a C++ project?
I feel like a lack of information on that.
All I found are always answers like:
download, build, install and done. But I'm already stuck on the "install" and "build".
The solution:
Close NetBeans.
Install and download MinGW from mingw.org
After installing, add the Path to your SystemEnvironemt (example: C:\MinGW).
go to Start->Computer, right mousebutton, select properties
go to advanced system setting, in the following dialog press "Environment Variables".
in the tab "system variables", find the entry Path (or PATH)
add: C:\MinGW;
get freeglut pre-compiled package:
(http://www.transmissionzero.co.uk/computing/using-glut-with-mingw/)
there is a good tutorial how to set up.
Now have fun (just #include " and you're done.
have fun.
Note #1:
if you have problems finding make, the folder is:
C:\MinGW\msys\1.0\bin\make.exe
(when installed MinGW on C:\MinGW).
"mingw-get install msys" in command line should get msys...
last but not least dont forget to add msys\bin to path, too. :)
here's a full tutorial, but in german language.
http://techchan.blog.de/2012/03/18/einrichten-opengl-netbeans-7-1-1-teil-0-start-13209096/
If you need it in english, let me know if you could translate it ;) otherwise i'll think about to translate it myself.
I had a difficult time getting glut working in Netbeans on Windows 7 until I found freeglut, I attributed this to the fact that glut is just very out of date and so are the tutorials I found.
Maybe this will help others looking for instructions on using freeglut in Netbeans. These instructions are like the ones in the link already provided, but help explain how to use it in Netbeans rather than from the command line. This tutorial expects that you've already gotten Netbeans and your compiler working together. IF you have not done so, I found the guide here very helpful: http://netbeans.org/community/releases/68/cpp-setup-instructions.html#mingw
download and extract freeglut from http://www.transmissionzero.co.uk/computing/using-glut-with-mingw/ into an easy to reach folder. (I recommend C:/FrGlut)
either add the bin folder (C:\FrGlut\bin) to your Windows PATH variable, or copy the freeglut.dll from your bin folder into C:\Windows\System32
Open Netbeans and open or create your project
go to: file->project properties
Select your compiler, go to include directories, and add the path to your freeglut include folder (C:\FrGlut\include)
under linker, select add libary, and navigate to the file C:\FrGlut\lib\libfreeglut.a
select options and add the following individually:
-dynamic -lfreeglut -lopengl32 -LC:\FrGlut\lib\libfreeglut.a
Netbeans should now be ready to use with your freeglut library.
To use the glut libary add the following include to your source:
#include <GL/glut.h>
Remember that freeglut.dll will need to be shared along with your executable in order for the program to run, as most users will not already have it.
