I’ve recently done a git clone of the wine repository at https://github.com/wine-mirror/wine and downloaded the folders to (~/repo/wine/). I'm trying to run Notepad, but don't know how. I am assuming that to build and compile it, I would need to run main.c from the notepad folder. I’m running GCC v 8.3.0 on Raspbian/Linux 10
With the repo downloaded as shown above, what build commands would I need to run notepad’s main.c from Geanie (or any, currently using Geanie) IDE? Can a single compile and/or build command let me run notepad from Geanie, or am I missing something?
Other details (not needed if what I thought I was going to do can't be done):
I wanted to try to run main.c at (~/repo/wine/programs/main.c), but don’t know how to get GCC to view all of the necessary header files. In my execution instructions window in Geanie, I have
gcc -Wall -c “%f” /home/pi/repo/wine/include
and my build instruction (it won't compile, so this isn't anything I've even gotten to work with yet...)
gcc -Wall -o “%e” “%f” /home/pi/repo/wine/include
When I attempt to compile, I get:
Stdio.h:11:10: fatal error: corecrt_wstdui.h: No such file or directory.
#include <corecrt_wstudio.h>
I went over to the stdio.h and attempted to add a build instruction here as well that also targets the include folder (which is the supposedly missing file), but it won’t compile.
Using cpp -v, I can see my include paths for GCC are as follows:
#include”...” paths:
#include<...> paths:
\usr\lib\gcc\arm-linux-gnueabihf\8\include
\usr\local\include
\usr\lib\gcc\arm-linux-gnueabihf\8\include-fixed
\usr\include\arm-linux-gnueabihf
\usr\include

I'm trying to set up CMake for a project I'm working on, and I'm first trying to compile a simple Hello World program in C. I'm using Windows 10 with MSYS2. If I invoke the compiler (GCC) directly in Bash, it compiles fine without warnings or errors and gives an executable as output which prints "Hello, world!" exactly as expected. My problem comes in when I try to use CMake to compile my project. When I run cmake -G Ninja .. to compile my project, it throws this error:
CMake Error at C:/msys64/mingw64/share/cmake-3.15/Modules/CMakeTestCCompiler.cmake:60 (message):
The C compiler
"C:/msys64/mingw64/bin/cc.exe"
is not able to compile a simple test program.
It fails with the following output:
Change Dir: C:/Users/dylanweber/Documents/C-Projects/webapp/build/CMakeFiles/CMakeTmp
Run Build Command(s):C:/msys64/usr/bin/ninja.exe cmTC_45340 && [1/2] Building C object CMakeFiles/cmTC_45340.dir/testCCompiler.c.obj

/bin/sh: C:msys64mingw64bincc.exe: command not found
ninja: build stopped: subcommand failed.
Notice how it mentions C:msys64mingw64bingcc.exe... there must be some kind of path delineation problem but I've tried setting the CC environmental variable to C:\\msys64\\mingw64\\bin\\gcc.exe and C:/msys64/mingw64/bin/gcc.exe. I have been clearing the CMake caches between runs.
Here is my CMakeLists.txt file:
cmake_minimum_required(VERSION 3.15)
project(webapp)
set(CMAKE_BINARY_DIR ${CMAKE_SOURCE_DIR}/build)
set(EXECUTABLE_OUTPUT_PATH ${CMAKE_BINARY_DIR})
set(LIBRARY_OUTPUT_PATH ${CMAKE_BINARY_DIR})
file(GLOB SOURCES "main/*.c")
add_executable(webapp ${SOURCES})
My code is in a "main" folder which is currently just one "main.c" file, in addition to a build directory used to keep all the temporary files in. The most frustrating part is that CMake was just working an hour ago, and I didn't change anything. What can I do to fix this problem?
The solution was not only installing the MinGW64 version of CMake, but also the MinGW64 version of Ninja as well. Since they have different pathing schemes compared to MSYS, they didn't play well together until they were both on the same POSIX-like platform.
I wrote a demo using libpq to connect to a PostgreSQL database.
I tried to connect the C file to PostgreSQL by including
#include <libpq-fe.h>
after I added the paths into system variables I:\Program Files\PostgreSQL\12\lib as well as to I:\Program Files\PostgreSQL\12\include and compiled with this command:
gcc -Wall -Wextra -m64 -I "I:\Program Files\PostgreSQL\12\include" -L "I:\Program Files\PostgreSQL\12\lib" testpsql.c -lpq -o testpsql
It first raised three errors, like
libssl-1_1-x64.dll is missing
libintl-8.dll was missing
libcrypto-1_1-x64.dll was missing
After I downloaded these three files and put them into I:\Program Files\PostgreSQL\12\lib, and compiled it again, it shows the error
The application was unable to start correctly (0xc0150002)
when I type testpsql. But if I type ./testpsql on git bash, it works. Anyone can please tell me why?
The code that I used was the first example from here.
Environment: PostgreSQL 12, Windows 10, MinGW64
“Download the DLL files” sounds dangerous. From where?
I would get rid of these files again. Since you probably don't reference these libraries from your code, it must be the dependencies of libpq.dll and are probably found in I:\Program Files\PostgreSQL\12\bin (if you used the EDB installer).
The problem is probably that you the PATH environment variable is different in git bash and in cmd.exe, and in the latter case not all required shared libraries can be found on the PATH. The solution is to change the PATH so that it includes all DLL files the executable requires, not to start copying around files.
It is probably enough to include I:\Program Files\PostgreSQL\12\bin in the PATH. To resolve missing dependencies, use a tool like dependency walker or this replacement.
So I have source code written in C for the LibIdn2 library. I am looking to port it into C# but running in to some issues along the way and would appreciate some help.
Installed Cygwin along with Make and GCC G++ packages
Successfully able to run the./configure command on the source directory
After this, running the "make" command produces an .exe file.
I have been trying to get a .dll file created but cannot seem to do so using gcc compiler. The command I am running is:
gcc -shared -o idn2.dll src/idn2.c
but it complains that it cant find the header files referenced in the idn2.c source file.
I have checked that in the idn2.h file, dll_Export is defined.
Any ideas how should I proceed? I need to get a dll.
I apologize if this seems like a stupid question, but I guess I am more used to packages that come with Makefiles or configure scripts.
I downloaded the Mongoose source tar file from the site, and untarred it.
I then tried to compile an executable out of it using
gcc -g -c mongoose.c -o main.o -lpthread -ldl.
However, after trying to execute, I get the error -bash: ./main.o: cannot execute binary file
When I looked into mongoose.c source, I did not find a main function.
Where can I get the main function so that the Linux mongoose web server can be compiled to work the same way as the Windows mongoose.exe?
Mongoose does come with a Makefile, and will compile as a standalone command-line program. Lua and SQLite are included.
The easiest way to compile the latest version is to cd into the "build" directory and run make unix. I'm not sure about the archived version on the downloads page, but trunk has been pretty stable.
I just checked out a clean copy of Mongoose from github earlier tonight and built it with no problems, so I can confirm that this works (assuming you have any other dependencies set up properly, of course).
It's because mongoose is not supposed to be used standalone, but to "embed" it into your program. You need to create a program which calls the correct function from mongoose.c.
Also, the -c flag to GCC tells it to create an object file, which needs to be linked to create an executable. So you try to execute a file which is not executable.
I'm writing a C project in Eclipse and while trying to run it I get the following error message:
(Cannot run program "make": Launching failed)
My Makefile is:

GenericHashTable.o : GenericHashTable.c GenericHashTable.h TableErrorHandle.h
gcc -Wall -c GenericHashTable.c -o GenericHashTable.o

gcc -Wall -c TableErrorHandle.c -o TableErrorHandle.o

Is the formatting broken in your makefile or in your question? Commands on the line below the target & dependencies. Does this makefile work from the command line?
Assuming the makefile is correct check the obvious things such as ensuring Eclipse can see your toolchain. Perhaps it can't even find the make command or you haven't set it from preferences.
Also the CDT offers a managed makefile and a standard (manual) makefile. The managed means Eclipse will create the makefile for you. The standard makefile is a makefile you are responsible for writing. Perhaps if your project is simple you should use the managed makefile to save yourself the hassle of writing one.
You can try the internal builder from eclipse:
Project->Properties->C/C++ Build
There (in the top level of C/C++ Build) you find Builder Settings->Builder Type which you set to Internal Builder. This way CDT does not require an external make command.
Either use the internal builder as "Turbo J" already suggested or make shure 'make' is in your PATH.
You can set the PATH for the build process in the Project-Properties in 'C/C++ Build -> Environment' - click "Select..", choose PATH and then change it by adding the correct path for the 'make' command.
This way you can also set the PATH of your compiler - that may be necessary if you use the Internal Builder.
