I have managed to build a static C library on OSX using make on the command line.
I have tried to use the same Makefile (with ARCHFLAGS=-arch armv6 -arch armv7) to build a static library for iOS, but it fails with:
gcc-4.2: error trying to exec '/usr/bin/arm-apple-darwin10-gcc-4.2.1': execvp: No such file or directory
I guess it is not working because I'm using the OSX SDK make instead of a some part of the iOS SDK. Any clues?
N.B. For more details on the library in question (levmar) and for the Makefile, please refer to this Stack Overflow answer.
You need to find:
the location of the iOS compiler
the command line options that are used in the command line invocation
The easiest way is to create a test iPhone/iPad app in XCode, build it, and then look at the build log to find how XCode invokes the compiler.
Can you just make an Xcode project and invoke Xcode on the command line or from a script? If you don't want the fuss of maintaining an Xcode project, an easier approach might be to use CMake to generate an Xcode project and then invoke Xcode on the command line or from a script. This way you can stay in the text-file and script domain the whole time.

I made a console C program that reads a .obj 3d model and unflatten it into a multipage PDF. At first I used a little PDF library (https://github.com/AndreRenaud/PDFGen) that worked fine and I was able to compile my code on Windows 11, but I needed to have text rotated and it wasn't possible with PDFGen, so I changed for Cairo Library (https://github.com/freedesktop/cairo). With Cairo my code does exactly what I want, but I didn't find how to compile it on Windows.
I'm using Geany to edit/compile my C code, my build command is :
gcc -Wall -o "%e" "%f" -lcairo -lm
I tried to do the same on Geany on Windows and it didn't work.
I found a repository with standalone cairo DLL for Windows, but didn't manage to use it.
I'm looking for another PDF library that could be used both on Linux and Windows, but for the moment didn't find any.
my code is here (https://github.com/gilboonet/Deplieur-C/blob/main/deplieur.c)
It's my first post here, I'm a long time C programmer but not IT pro and I'm not a Windows user, I only want to compile my code on it because lots of people that will use my program are windows users. Thank you.
I've found a project called "cairo-windows" on Github that creates resources needed to build a C project using Cairo, and it works, even if I needed to use Visual Studio. Sadly, it seems to have problem with pdf creation that only creates a blank file. To make it work I changed the resources (dll and includes) it needs to build the project to those from my gtk windows build it comes with Cairo 1.16.0. If you want to do the same, you must replace the extern directory from cairo-windows (initially fetched by setup-win32.py): lib by cairo.lib, cairo.dll expat.dll fontconfig-1.dll freetype-6.dll and libpng16.dll from your gtk build (..gtk\x64\release\bin) and include by the content of ..\gtk\x64\include.
So I'm in terminal, and have a directory called CAPTURE on my desktop, I'm trying to run a program called 'testme'. I read that you need to have build-essential installed but I think that's only on Linux systems and I'm on a Mac so it wasn't necessary because it's already built in (I think). So, I navigated from ~ with:
cd Desktop/CAPTURE
Then, I tried running a bunch of different commands that I found while looking on the internet:
./testme
which returned zsh: exec format error: ./testme
xcode-select --install
which installed properly and I thought I could run the ./testme command but I got the same error as before. Then I tried navigating to the directory again and used
chmod +x ./testme
./testme
which also did not work. I've never run executables before so I really have no familiarity with these commands so they might be super wrong. If anyone can help me run the file properly, that would be much appreciated.
Since your question is tagged as C and Clang, and you are talking about build-essential, I will assume that you are attempting to build an application from source code.
Instead of build-essential, in macOS, you need Xcode. The Xcode CLI tools will work if the application is text-only or Curses, but you will need the entire Xcode IDE for any graphical application.
If running ./testme is telling you Executable format error is probably because it's a prebuilt executable, very likely a Linux ELF executable that will not run in macOS.
My suggestion is to try to build the software. Most C applications will build if you run make inside the directory. make is installed by default by Xcode. Other applications may need a third-party build system, such as CMake, but I do not know if that's the case.
My question may completely be a noob. Sorry, for that but I have been trying to compile my first Cuda code in Xcode and I'm lost where and how I could set up the IDE to invoke NVCC.
I installed the latest CUDA toolkit CUDA 6.0 and have even installed GCC 4.8 using brew. I have XCODE 5.5
When I run my code from XCODE all the directives like global are marked as unidentified.
I don't where and to change the settings to invoke NVCC. I will be really thankful, if anyone could help me with this.
Further, when I created the XCODE project, I created it as a C project. So, I placed the CUDA code in this C file, which is what is giving me the above mentioned errors. I tried to replace this .C file with a .cu file (just change the extension), which too failed badly - XCODE didn't even know what to do with the .cu files
COuld anyone please help me?
Thanks in Advance
I have given it a try. Although I have not completely succeeded I thought I'd post my progress here in hopes of helping others. The steps I took were inspired by this page.
Create a new Xcode project
Under Build Settings add a new user defined setting CC with the value /usr/local/cuda/bin/nvcc.
Add /usr/local/cuda/include to Header Search Paths under Build Settings.
Set Enable Modules (C and Objective-C) to No.
Add /usr/local/cuda/lib/libcuda.dylib to Link Binary With Libraries under Build Phases.
For any C files you create set their extension to .cu in the File Inspector, after you have done that you have to set the type of that file to C source to get syntax highlighting, by going to Editor->Syntax Coloring->C.
Problems with this setup:
- Xcode can't run the executable, at least nog if it is compiled for debugging. However you can make it copy the executable to some reasonable location and run it in the terminal.
- Whenever you try 'Build for running' sometimes Xcode magically destroys the whole project.
I migrated my program built with gtk+3.0 from linux to Mac OS X(10.6.8).
And I compiled the program without errors.
However, after I started the program and I chose to open a file, the terminal shows following message.
GLib-GIO-CRITICAL **: Settings schema 'org.gtk.Settings.FileChooser' is not installed
Then, the program ends with Segmentation fault.
How to solve it?
Thanks for any helps.
Seems you're not the one having this problem, and it also happens on Windows on MinGW. Luckily, that person gave a solution:
The thing, as it seems as I was running the test-widget example (that I
built with gtksourceview-3.0.0 using MSVC), was that I need to compile the
org.gtk.Settings.FileChooser.gschema.xml file (from GTK+-3.x, under
$(srcroot)/gtk) with the glib-compile-schemas utility that is from GLib,
which will generate gschemas.compiled in the same folder.
After that, place that gschemas.compiled file in the this folder:
$(parent_folder_of_the_gtk3_dll)\share\glib-2.0\schemas
and one will be set to use the gtkfilechooser without the puzzling
[GLib-GIO-ERROR **: Settings schema 'org.gtk.Settings.FileChooser'
is not installed] error.
I will add to my GLib project files to compile the glib-compile-schemas
utility and add to my GTK+-3.x project files to compile the
the org.gtk.Settings.FileChooser.gschema.xml shortly.
I ran in to this problem with a program that I crosscompiled with mingw for windows, the solutions is to run glib-compile-schemas [path to org.gtk.Settings.FileChooser.gschema] in my case was that file in ./share/glib-2.0/schemas.It will generate gschemas.compiled, that is the file FileChooser is looking for.
I'm trying to compile a downloaded program in Windows. The program is usually run in Linux, but is programmed to also run in Windows (the code has #if defined(_WIN32)'s in it, and claims to work with borland free tools). When I try to use make from the command line, it tells me "Incorrect command line argument: -C". In the makefile, there are many lines that say "make -C" followed by a directory name. Does this syntax not work in Windows? What is a correct way to do this? Is there any way to compile this for native use in Windows with this makefile?
Windows itself doesn't come with a make utility. Microsoft does have a 'make' utility that comes with their development tools (such as Visual Studio, the Platform SDK, or the Windows Driver Kit) but it's called nmake.
You probably need GNU make to process those makefiles. you can get a copy for Windows here:
http://unxutils.sourceforge.net/
However, if the makefile isn't written to be able to be run on Windows, it'll probably not work well. You'll also need to make sure you have whatever other development tools the makefile calls upon (maybe the Borland compiler or GCC), and there may be other configuration that needs to be done specific to the project you want to build. It's probably not a matter of just having the correct make utility.
-C is "change working directory" only for the gmake command (from the GNU package). You should take a look in the manual for your Make-Utility and see, wheather it supports something äquivalent.

Are you using cygwin?
Are there any instructions for installing on windows(perhaphs in a README file)?
