How do I compile objective-C in code blocks?










2














I downloaded Codeblocks bundled with GCC from here



The C part is running fine



I read this wiki tutorial which says having GCC will allow me to compile objective C by just adding -lobjc to the compiler options



However, I have followed the steps mentioned in this tutorial and added the -lobjc option, but it doesn't compile



enter image description here



This is the build error message I get in codeblocks:



-------------- Build: Debug in test_prog_proj (compiler: GNU GCC Obj-C Compiler)---------------

mingw32-gcc.exe -Wall -g -c D:backupcb_filesobjc_filestest_prog_projtest_prog.m -o objDebugtest_prog.o
mingw32-gcc.exe: error: CreateProcess: No such file or directory
Process terminated with status 1 (0 minute(s), 2 second(s))
1 error(s), 0 warning(s) (0 minute(s), 2 second(s))


As shown above, it does not show the -lobjc option



I have also tried manually compiling the above program in Windows cmd by going into the folder containing the .m file. I gave the following command:



mingw32-gcc.exe -Wall -g -c D:backupcb_filesobjc_filestest_prog_projtest_prog.m -o objDebugtest_prog.o -lobjc 


But I get the same error in cmd



mingw32-gcc.exe: error: CreateProcess: No such file or directory 


I also tried



gcc -g -fgnu-runtime -O -c some_class.m 


that I got from here, but it gives me the same CreateProcess error. How do I start compiling Objective C code in Windows (preferably using GCC and Codeblocks) ?



--- EDIT 1 ---



I did as suggested in Mike Kinghan's answer below, and uninstalled my older Codeblocks instgallation, then reinstalled MinGW and codeblocks separately. The Codeblocks uninstall removed the Codeblocks folder in Program Files, but when I reinstalled Codeblocks again (version without MinGW bundled together), the "GNU GCC Obj-C" settings I made with the previous installation was still there, along with the -lobjc flag in the "linker settings" tab.



However, the problem is that it's still not working. I get the following error if I try to build from Codeblocks



Goto "Settings->Compiler...->Global compiler settings->GNU GCC Obj-C Compiler->Toolchain executables" and fix the compiler's setup.

Tried to run compiler executable 'C:Program FilesCodeBlocksMinGW/bin/mingw32-gcc.exe', but failed!

Skipping... Nothing to be done (all items are up-to-date).


This is what Toolchains executable looks like:

mingw32-gcc.exe -Wall -g -c D:backupcb_filesobjc_filestest_prog_projtest_prog.m -o objDebugtest_prog.o -lobjc 


it gives the error



mingw32-gcc.exe: error: CreateProcess: No such file or directory 


What is the problem here?



--- EDIT 2 ---



Following the suggestion in Mike Kinghan's answer I deleted the old instance of "GNU GCC Obj-C Compiler" in the list of compiliers, and recreated with the current version of "GNU GCC Compiler"



However, the program still does not work. This is the message I get in the build log:



-------------- Build: Debug in test_prog_proj (compiler: GNU GCC Obj-C Compiler)---------------

Linking stage skipped (build target has no object files to link)
Nothing to be done (all items are up-to-date).


Cleaning the project and then building it again gives the same message. Trying to run the project anyway gives me a dialog box saying the project is not built, and clicking on Yes to build the project just pops the same "project not built yet" dialog box up again. The file icons in the Workspace tree of the Projects tab also seem to be grayed out:

I have added -lobjc in Linker Settings as mentioned here as well.



I right clicked the project icon in the Project tree, went to Build Options and added -lobjc in the Linker Settings as well:



enter image description here



What is the problem with this project at the moment?



--- EDIT 3 ---



I ended up completely uninstalling Codeblocks (uninstall from windows start menu, delete codeblocks folder in %APPDATA%), uninstalling MinGW (deleting the c:MinGW folder) and reinstalling everything from scratch. I followed all the instructions in the Wiki (except the Troubleshooting section, but I think that part is irrelevant) and it still doesn't work (same problem as described in Edit 2 in this post).



How do I get Codeblocks to detect and compile obj-C code? Also, it is not showing me the compiler command line arguments when I try to build it from the Codeblocks interface. Why is this and how can I get it to show me whatever the full command line it is using?

  • Somewhere beneath the libexec folder of your MinGW installation you will find a program called cc1.exe. (In my case, C:MinGWlibexecgccmingw326.3.0cc1.exe). In the same folder as cc1.exe, do you see a program called cc1obj.exe?

The GCC program we loosely call the "the compiler" - [mingw32-](gcc|g++) -
is actually a compiler/linker frontend that invokes a real language
compiler and/or linker depending on what the input files and commandline options
indicate you want it to do.



Input files with an .m extension indicate they are Objective C source files
that are to be compiled with the GNU Objective C compiler, cc1obj. But you
haven't got it. Hence the failure you see.



A GCC installation will include the C compiler cc1 and, optionally, compilers
for other languages - C++, Fortran, Objective (C|C++), Go ... You say you got your MinGW GCC installation as
bundled with Code::Blocks. That bundled MinGW omits the Objective C compiler, cc1obj , because the maintainers
reckon it a niche language.



Best remove your CB installation and bundled MinGW and then install MinGW GCC independently from
one of the rival projects:-



https://sourceforge.net/projects/mingw-w64/
https://sourceforge.net/projects/mingw/


Run the installer and ensure that you get Objective C as well as any other compilers you
want.



After that, replace your CB installation it with the codeblocks-17.12-setup.exe installer (not codeblocks-17.12mingw-setup.exe),
from https://sourceforge.net/projects/codeblocks/files/Binaries/17.12/Windows/. This installer includes no compilers and
will auto-detect your MinGW installation.



Then proceed as you already did to create a GNU GCC Obj-C compiler setup in the CB IDE.



Later ... still not working



Your GNU GCC Obj-C compiler-setup has persisted from your previous
CB install and has been rendered out-of-date by the fact that your
new MinGW installation is no longer part of Code::Blocks. As you see,
it still looks for the toolchain executables in C:Program FilesCodeblocksMinGW,
whereas your new MinGW is somewhere else.



When you reinstalled Code::Blocks you should have seen its attempt to auto-detect compilers,
and that it detected your MinGW toolchain in (say) C:MinGW. It will have configured
a compiler setup for GNU GCC Compiler on that basis, with the correct path to
the toolchain executables. But it will not have modified any persisting compiler setups that
you created yourself, such as GNU GCC Obj-C.



First check that the auto-detected setup GNU GCC Compiler is good just
by creating a "Hello world" C console project and seeing that you can build it.
I assume you'll be able to, but if not, then go into the GNU GCC Compiler setup
yourself and manually set the Compiler's installation directory correctly.



Then, set the same Compiler's installation directory for your GNU GCC Obj-C
compiler setup.

  • Well your compiler is now being found and run :) - which solves the original problem and reveals some new one. Clean the project (Menubar -> Build -> Clean), then Build -> Build; then post the complete contents of the Build log (not Build messages) tab if it is at all different from what you already posted. If Clean produces any errors, then post that log first.

Run the installer and ensure that you get Objective C as well as any other compilers you
want.



After that, replace your CB installation it with the codeblocks-17.12-setup.exe installer (not codeblocks-17.12mingw-setup.exe),
from https://sourceforge.net/projects/codeblocks/files/Binaries/17.12/Windows/. This installer includes no compilers and
will auto-detect your MinGW installation.



Then proceed as you already did to create a GNU GCC Obj-C compiler setup in the CB IDE.



Later ... still not working



Your GNU GCC Obj-C compiler-setup has persisted from your previous
CB install and has been rendered out-of-date by the fact that your
new MinGW installation is no longer part of Code::Blocks. As you see,
it still looks for the toolchain executables in C:Program FilesCodeblocksMinGW,
whereas your new MinGW is somewhere else.



When you reinstalled Code::Blocks you should have seen its attempt to auto-detect compilers,
and that it detected your MinGW toolchain in (say) C:MinGW. It will have configured
a compiler setup for GNU GCC Compiler on that basis, with the correct path to
the toolchain executables. But it will not have modified any persisting compiler setups that
you created yourself, such as GNU GCC Obj-C.



First check that the auto-detected setup GNU GCC Compiler is good just
by creating a "Hello world" C console project and seeing that you can build it.
I assume you'll be able to, but if not, then go into the GNU GCC Compiler setup
yourself and manually set the Compiler's installation directory correctly.



Then, set the same Compiler's installation directory for your GNU GCC Obj-C
compiler setup.

  • Well your compiler is now being found and run :) - which solves the original problem and reveals some new one. Clean the project (Menubar -> Build -> Clean), then Build -> Build; then post the complete contents of the Build log (not Build messages) tab if it is at all different from what you already posted. If Clean produces any errors, then post that log first.

The GCC program we loosely call the "the compiler" - [mingw32-](gcc|g++) -
is actually a compiler/linker frontend that invokes a real language
compiler and/or linker depending on what the input files and commandline options
indicate you want it to do.



Input files with an .m extension indicate they are Objective C source files
that are to be compiled with the GNU Objective C compiler, cc1obj. But you
haven't got it. Hence the failure you see.



A GCC installation will include the C compiler cc1 and, optionally, compilers
for other languages - C++, Fortran, Objective (C|C++), Go ... You say you got your MinGW GCC installation as
bundled with Code::Blocks. That bundled MinGW omits the Objective C compiler, cc1obj , because the maintainers
reckon it a niche language.



Best remove your CB installation and bundled MinGW and then install MinGW GCC independently from
one of the rival projects:-



https://sourceforge.net/projects/mingw-w64/
https://sourceforge.net/projects/mingw/


Run the installer and ensure that you get Objective C as well as any other compilers you
want.



After that, replace your CB installation it with the codeblocks-17.12-setup.exe installer (not codeblocks-17.12mingw-setup.exe),
