I'm pretty new to C::B and just installed it along with building wxWidgets. I'm pretty sure my wxWidgets build with MinGW is good, i was able to successfully create a wxWidgets project in C::B using the "minimal.cpp" sample in wxWidgets. However now instead of creating an empty project, I'm using leaving "Empty project" unchecked in wizard to create the program. With wxWidgets this creates 2 source files and 2 header files (for app and main). When I try to build+play the project though without making any changes i get this error:

Saying that it can't find files? the wxWidgets-3.0.5 is actually in c:\Program Files/wxWidgets-3.0.5, so maybe its looking in the wrong place? Or maybe I missed a step setting it up?
This is absolutely everything I did to install C::B, install wxWidgets, and create my project
1. Installing CodeBlocks
a. Clicked codeblocks-20.03mingw-setup.exe from website, then download started automaticallty from fosshub
b. Ran executable to install and for type of install did "All plugins, all tools, just everything"
-all checkboxes were checked, including
1. Default Install
2. Contrib Plugins
3. C::B CBP2Make
4. C::B Share Config
5. C::B Launcher
6. MinGW Compiler Suite
2. Downloading wxWidgets
a. Clicked "Windows ZIP" from downloads page on website under "Latest Stable Release: 3.0.5"
b. Extracted download to c:\Program Files\wxWidgets-3.0.5
-first file asked for administrator permission, i said "dont ask again" and clicked "continue"
3. Added MinGW to path
a. went into c:\Program Files\CodeBlocks\MinGW\bin and copied that path to PATH environment variables
4. Building wxWidgets
a. opened a terminal with admin privileges and went to c:\Program Files\wxWidgets-3.0.5\build\msw.
b. entered commands as suggested at https://wiki.wxwidgets.org/Compiling_wxWidgets_with_MinGW, except changed
BUILD=release to BUILD=debug:
1. mingw32-make -f makefile.gcc SHARED=1 UNICODE=1 BUILD=debug clean
2. mingw32-make -f makefile.gcc SHARED=1 UNICODE=1 BUILD=debug
c. wxWidgets successfully built (3:38 pm to 4:22pm!)
5. Opened CodeBlocks
a. got message that "After auto-detection, at least one compiler's master path is still empty and therefore invalid.
Inspect the list below and change the compiler's master path later in the compiler options. Select you favourite
default compiler here:"
-There's one compiler listed as detected: GNU GCC Compiler
-With this compiler highlighted, i clicked "Set as default" and then ok.
b. got message CodeBlocks is not default app for C/C++ source files.
-Selected "Yes, associate with C/C++ files"
7. Testing Compiler
-I wasn't sure what to do about "setting compiler master path..." msg earlier, so I just created a new project with type
"Console application", compiled the basic "Hello world" application, ran it, ran fine, so I assume compiler is working?
6. Create new wxWidgets program:
a. Create new project: wxWidgets project
b. Wizard Steps:
PAGE 1:
-Set version: wxWidgets 3.0.x
PAGE 2:
-Named project "MULLSIMPLE" and created directory
PAGE 3:
-Skipped Author info.
PAGE 4:
-Preferred GUI Builder: None
-Application Type: Frame Based
PAGE 5:
-wxWidgets location: C:\Program Files\wxWidgets-3.0.5
-When I hit next, it opens the global variable editor. I don't know how to use this,
so i just hit ok without making any changes. IT asked if i want to save an invalid global var,
i said yes. Now the widgets location in the wizard is a path instead of a global variable,
I assume this is ok for now
PAGE 6:
-By default "Debug" configuration checked, "Release" configuration is unchecked
-make no changes
PAGE 7:
-Under wxWidgets library settings:
-CHECK Use wxWidgets DLL
-UNCHECK wxWidgets built as monolithic
-CHECK enable unicode
-Under Miscellaneous settings:
-UNCHECK create empty project
-CHECK create and use PCH
-Leave configuration input field blank
-UNCHECK Configure Advanced Options
-On next get dialog re PCH default settings, click YES to accept
PAGE 8:
-Didn't select any additional libs to add to project,
just hit finish
8. Try Build and run
-Get the build log error at start of post re: missing files
Thanks
#user4581301 thanks for your response it looks like that was the problem. I copied the wxWidgets-3.0.5 to the desktop. Then i opened up the old one in prog files, cleaned the build, then deleted that folder. Then i created a new C::B proj using the wxWidgets path to the one on the desktop, and now the error is gone.
I don't 100% understand how wxWidgets works so I hope just copying the whole folder to another location is fine, but so far program seems to be working. Thanks

I have installed the latest gcc version, without overwriting the existing one, so now I have two differents gcc versions installed. My question is how do I set eclipse CDT (luna version) to use such version? I've tried by setting in project, properties, C/C++ Build environment and changing the path variable, but it doesn't work.
Specifically the problem I have is:
make all
Building file: ../main.cc
Invoking: Cross G++ Compiler
g++ -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"main.d" -MT"main.d" -o "main.o" "../main.cc"
g++: error trying to exec 'as': execvp: No such file or directory
make: *** [main.o] Error 1
I changed the path variable to point to the binaries of the the gcc version i've installed.
More Info:
The OS is Red Hat
Please check if you have set the "PATH" in "Environment Variables" correctly
("My Computer -> Properties ->Advanced Settings -> Environment Variables").
Open a cmd prompt and type
echo %PATH%
Verify if the required compiler path is set correctly.
Now restart the Eclipse Luna to get the changes fetched. (Sometimes a system restart is also required)
I have already read the other questions on the site and none of them matched with the issue I had.
I have already tried unistalling and then reinstalling codeblocks.
Please help.

I have successfully solved the problem.
All I did was go to "Compiler Settings" ("Settings" -> "Compiler" -> Global compiler settings), and selected "Reset Defaults".
It solved the problem.
Thanks everyone for answering. :)
Start by turning on full Compiler logging.
This is done by selecting the "Full command line" option Under menu "Settings" -> "Compiler" -> Global compiler settings -> [the compiler you use] -> "Other Setting" tab, "Compiler logging". In 12.11 and newer this is enabled by default.
This option will make Code::Blocks output the exact commands it uses to compile your code.
Things to remember:
Look at the "Build Log" NOT the "Build Message" tab
Do a re-build instead of build in order to get a full build log.
You should review all the commands and their options;
If you have compiled your app before, do a re-build (or clean before build) to see all compiling / linking steps;
If you don't know what an option or a command does please read the documentation for the compiler/linker you're using;
Look for missing commands;
For every source file (.cpp; .c; .d; etc) in your project, you must have at least one command in the log. This command must produce an object file (file extension .o if using gcc/g++ and .obj if using Visual Studio);
Every object file should be linked in the final executable, if not there are undefined symbols errors;
Remember the file extension matters: *.c is compiled as C file, *.cpp is compiled as C++ file.
If you have no luck, you can try to ask in the forum, but read first "How do I report a compilation problem on the forums"
From Code::Blocks FAQ
I downloaded GLFW 3.1.1 and followed a tutorial telling me to:
Drop glfw3.h into MinGW's include folder
Drop the contents of lib-mingw in the downloaded file into MinGW's lib folder
Run the test program that comes with GLFW
After doing this I kept running into an error that stopped me from even starting a new GLFW project as the wizard kept looking for glfw.h and glfw.dll when they're now glfw3.h and glf3.dll I edited the wizard and was finally able to get the new project open.
After that, I clicked build and run and the compiler asked if I was sure. When I clicked yes it continually asked me if I wanted to build and run. The debugger just gives me this and I'm not sure what I set up wrong.

You should avoid using the wizard for GLFW projects because it's for an outdated version of GLFW.
You should create a console application then go to Project->Build Options. Go to the Linker settings tab then add glfw3, opengl32 and gdi32, then click OK.
You can now test if it worked by copying the sample code on the GLFW website's documentation page and pasting it in main.cpp, replacing everything and running the program.
i want to get started with QT. I donwloaded QT5 MINGW compiler with QT creator and i am trying to build the pre attached example named affine the problem is that the QT5 i think embed the project name with each of source file and thus gives error that file not found. some thing similar
:-1: error: ..affinemain.cpp: No such file or directory
while the file name is just
main.cpp
i don't know how to fix it. I searched lot on internet but could not found anything useful.
I even try to compile from command prompt but i am not fimmiliar with command prompt compiling as i am new to QT and previously i am totally developed with IDE in visual studio and eclipse for java so i have no idea about the make file and compiler command line arguments.
could some body please help me to fix this issue and can you tell please why compiler attaching project name with the source file name?
Thanks in advance
I have got the same problem and my solution may help you.
I am working with Qt5.0.1 now, and there are two distributions to work on windows with it: Qt5.0.1-mingw and Qt5.0.1-msvc2010.
I had to use mingw and there was a problem on my setup that "/" is ignored in path's.
So according to Qt Creator, compiler was called to process file mainwindow.cpp and this file was passed to it
g++ /*truncated*/ ..\qt-example\mainwindow.cpp
Below is the full compiler input:
g++ -c -pipe -fno-keep-inline-dllexport -g -frtti -Wall -Wextra -fexceptions -mthreads -DUNICODE -DQT_QML_DEBUG -DQT_DECLARATIVE_DEBUG -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -DQT_OPENGL_ES_2 -DQT_OPENGL_ES_2_ANGLE -DQT_NEEDS_QMAIN -I..\qt-example -I"..\..\..\..\..\..\Qt\Qt5.0.1\5.0.1\mingw47_32\include" -I"..\..\..\..\..\..\Qt\Qt5.0.1\5.0.1\mingw47_32\include\QtWidgets" -I"..\..\..\..\..\..\Qt\Qt5.0.1\5.0.1\mingw47_32\include\QtGui" -I"..\..\..\..\..\..\Qt\Qt5.0.1\5.0.1\mingw47_32\include\QtCore" -I"debug" -I"." -I"." -I"..\..\..\..\..\..\Qt\Qt5.0.1\5.0.1\mingw47_32\mkspecs\win32-g++" -o debug\mainwindow.o ..\qt-example\mainwindow.cpp
And the error produced.
g++.exe: error: ..qt-examplemainwindow.cpp: No such file or directory
g++.exe: fatal error: no input files
compilation terminated.
So, we can see that "\" is ignored by the compiler and file name is merged with directory name.
The solution to that problem goes to the tools that are used - MinGW (Minimalist ports of GCC and Binutils). And also MSYS - a collection of GNU utilities such as bash, make, gawk and grep to allow building of applications and programs which depend on traditionally UNIX tools to be present. In our case - g++.
MSYS is not shipped with Qt5.0.1-mingw and g++ is not using it, but having MSYS available in your PATH environment variable breaks the system.
MSYS is used for git scm, which I have installed, so my path contains links to MSYS that goes bundled with git. So I have next paths in my PATH environment variable.
C:\Program Files (x86)\git\bin;C:\Program Files (x86)\git\cmd
I have not found how MSYS is used by Qt Creator or g++, or where it is linked, but when I have dropped next path from PATH:
C:\Program Files (x86)\git\bin;
and restarted Qt Creator - g++ succeeded on compiling my file, it worked.
The question why/how it influences the Qt Creator/g++ that should not use MSYS utils installed with git is still open.
i can´t comment.
important : delete all the files in the release and debug folder (compiled version) before try the tips of the autor ...
I have cygwin installed, and I want to use Eclipse with CDT for development under Windows 7. However, I get following error:
**** Build of configuration Default for project hello_cpp ****
make all
g++ -O2 -g -Wall -fmessage-length=0 -c -o hello_cpp.o hello_cpp.cpp
process_begin: CreateProcess(C:\cygwin\bin\g++.exe, g++ -O2 -g -Wall -fmessage-length=0 -c -o hello_cpp.o hello_cpp.cpp, ...) failed.
make (e=5): Access denied.
make: *** [hello_cpp.o] Error 5
**** Build Finished ****
I'm able to use g++ as standalone compiler.
cygwin /bin folder is
added to path.
After googling I found out that C:\cygwin\bin\g++.exe is a cygwin symbolic link and Windows doesn't understand it and I need to point to the g++-3 location directly. How do I do it?
I think you've done something wrong and need to start over again. Just installed Cygwin and Eclipse CDT (Indigo) on my Windows 7 and all works fine and auto-magicaly for me.
Here's what I did and I think you need to do:
Get the latest Cygwin (yes, get it again! get rid of the old one just to be sure)
During the installation make sure to select gcc, gcc-g++ and make (I additionally installed couple of other things like gcc4, w32api but it's optional)
Start Cygwin terminal to init all configuration files, etc. See if g++ executes and close the terminal.
Add C:\cygwin\bin (or wherever else you installed it) to your Environment PATH variable
Get Eclipse CDT, extract it somewhere and start it up.
Go to File -> New Project -> C++ Project and select Hello World C++ Project. You should see the Cygwin GCC in the Toolchains list.
Create the Project, build and run it!
Done!
Build output:
