（__ printf __）在DLL（programfiles（x86）\\ codeblocks \\ mingw \\ bin \\ as.exe）中找不到

Question

I'm trying to learn wxwidgets for cross platform GUI development, however I faced a problem.

When try to build wxwidgets with mingW32 I run into errors. I installed minGW32 with codeblocks 16.1 (works fine), added PATH to System Environment. Downloaded all possibilities from wxwidgets.org. None of them wants to compile when I try to compile wxwidgets library from cmd with mingw32. I go into wxwidgets/build/msw , typed several versions but to mention one:

mingw32-make -f makefile.gcc BUILD=release SHARED=1 MONOLITIC=1 UNICODE=1

(tried without shared, monolitic, even debug mode)

About the error:

( __ printf __ ) cannot be found in DLL
(programfiles(x86)\codeblocks\mingw\bin\as.exe)

I have the exe, tried to reinstall everything from scratch several times. I'm using Windows 10.

gcc -c -o gcc_mswudll\wxregex_regcomp.o  -O2 -mthreads  -DHAVE_W32API_H -DNDEBUG -I..\..\include -I..\..\lib\gcc_dll\mswu -D__WXMSW__  -D_UNICODE   -MTgcc_mswudll\wxregex_regcomp.o -MFgcc_mswudll\wxregex_regcomp.o.d -MD -MP ../../src/regex/regcomp.c
makefile.gcc:5778: recipe for target 'gcc_mswudll\wxregex_regcomp.o' failed
mingw32-make: *** [gcc_mswudll\wxregex_regcomp.o] Error 1

Update:

After reinstalling and deleting everything connected to this, the problem has changed. The code I use, tried without the flag, and with flag but only"-std=gnu++11" too:

mingw32-make -f makefile.gcc SHARED=1 UNICODE=1 BUILD=release CXXFLAGS="-fno-keep-inline-dllexport -std=gnu++11"

The new error code:

gcc -c -o gcc_mswudll\wxregex_regcomp.o  -O2 -mthreads  -DHAVE_W32API_H -DNDEBUG -I..\..\include -I..\..\lib\gcc_dll\mswu -D__WXMSW__  -D_UNICODE   -MTgcc_mswudll\wxregex_regcomp.o -MFgcc_mswudll\wxregex_regcomp.o.d -MD -MP ../../src/regex/regcomp.c
gcc: error: CreateProcess: No such file or directory
makefile.gcc:5702: recipe for target 'gcc_mswudll\wxregex_regcomp.o' failed
mingw32-make: *** [gcc_mswudll\wxregex_regcomp.o] Error 1

Any infos about the fact that I could not ever compile wxwidget with codeblocks' built in compiler? without addons?

Delete everything: wxWidgets, Code::Blocks and MinGW or TDM-GCC

* Download and install C::B, without MinGW or TDM
* Download TDM-GCC from here . If you install both 32 & 64 bits versions I suggest you to install them in two different folders.
* Download wxWidgets

Open a command window. Say you have TDM at "C:\\TDM32" and wxWidgets at "C:\\myWX".
Use these commands to compile wxWidgets:

PATH=%PATH%;C:\TDM32\bin
cd C:\myWX\build\msw
mingw32-make -f makefile.gcc BUILD=release SHARED=1 MONOLITIC=1 UNICODE=1

This should build an only .dll file with most of wxWidgets. Not OpenGL.
If you prefer several .dll don't use "Monolitic=1"
If you prefer not using wx'dlls, but static '.a' files added to your app, don't use "shared=1"
If you want to step into wxWidgets code when using a debugger, use "BUILD=debug"
If you want OpenGL use "USE_OPENGL=1"
To build wxWidgets with C++11 use CXXFLAGS="-std=gnu++11"

For your own app you must tell C::B:
* where the TDM compiler can be found
* where the wxWidgets headers can be found
* where the wxWidgets libraries (.dll or .a depending if you compiled with "shared") can be found
