Getting a basic wxSmith/wxWidgets to compile/link

[ermano]

Good afternoon,

there is a problem that bugs me now for several days already and I just don't know how to solve it:

After some hiccups I can compile wxWidgets3.0.0 using the latest TDM-GCC (tdm64-gcc-4.8.1-3.exe) without any problems using the syntax:

mingw32-make -j4 -f  makefile.gcc MONOLITHIC=1 SHARED=1 UNICODE=1 BUILD=release TARGET_CPU=X64  2>_Error.log (same with "debug").
After compilation I get (in C:\wxWidgets-3.0.0\lib\gcc_dll) the  libwxmsw30u.a and  libwxmsw30ud.a for the release and the debug version respectively.

When starting C::B  13.12 I use:
Favourite Gui Builder: wxSmith -> Frame Based
wxWidgets Location: C:\wxWidgets-3.0.0
GNU GCC Compiler, "Create Debug" and "Create Release" are both ticked
"Use wxWidgets DLL", "wxWidgets is build as a monolithic library" and "Enable unicode" -> all ticked
"Create and use precompiled header (PCH)  is also ticked

In the C::B toolchain the C++ compiler is: x86_64-w64-mingw32-g++.exe (same for linker for dynamic libs) and ar.exe the one for static libs.

After creation of the new project with the above selections I immediately try to compile the "Hello World" equivalent of wxSmith.
In the past (using prior versions of C::B and wxWidgets) this went through without problems.
Now, however I get through the compilation process ok but the linker tells me: "ld.exe cannot find -lwxmsw30ud". (in Debug)
This is no surprise because there is no "lwxmsw30ud". The wxWidgets compilation yielded "libwxmsw30ud.a" so with a "lib"
in front of lwxmsw30ud.
Simple cheating tricks like changing libwxmsw30ud to lwxmsw30ud did not solve the problem either.

In the "Global compiler settings" -> Search Directories -> Compiler (Linker) I gave: "C:\wxWidgets-3.0.0\lib\gcc_dll"
The Global variable Base is also set to the correct path.

In the "Project Build options" -> Linker Settings I have the correct library name specified libwxmsw30u/d respectively for release/debug)

I have no clue why C::B always defaults to "lwxmsw30ud". There is also no trace of "lwxmsw30ud" in the Projects "cbp" -file
I somehow suspect that this is a matter of a 32/64 bit conflict without really knowing how to resolve this.
Nevertheless in an other attempt I also erased my wxWidgets directory completely and recompiled it omitting the   
"TARGET_CPU=X64" option in the wxWidgets compilation. The result was however the same.
My system is Windows Professional 7.

Any help would be greatly appreciated:  Hermann

Good morning,

since there was no way to get it to run I completely de-installed everything (wxWidgets and CB) and subsequently erased the
containing folders.
For the re-installation I used the gcc compiler that comes with CB 13.12 which I also used to
recompile wxWidgets with the standard settings (after a "clean"):
"mingw32-make -j4 -f  makefile.gcc MONOLITHIC=1 SHARED=1 UNICODE=1 BUILD=release   2>_Error.log " (same for "debug")

I can compile a basic and unaltered wxSmith program now (wizard settings as above), but when I start it, it crashes immediately.

The debugger message is also not very inspiring:

[debug][New Thread 1616.0x990]
[debug]Program received signal SIGSEGV, Segmentation fault.
[debug]0x00b25d96 in wxEventHashTable::wxEventHashTable (this=0x47916c <_fu30___ZN7wxFrame13sm_eventTableE>, table=...) at ../../src/common/event.cpp:915
[debug]C:\wxWidgets-3.0.0\src\common\event.cpp:915:30003:beg:0xb25d96
[debug]>>>>>>cb_gdb:

Would anybody know how to solve this issue ?

Last not least, there is another thing I do not understand. Upon de-installing CB completely (+ erasing the CB folder)
and re-installing it again it still remembers all the settings that there were before. When I launch CB all the history
of projects is still there as well as the (old) compiler (and other) settings.
What do I have to do, to do a full "clean-up" in order to re-start from scratch  ?

Thanks for your help!

The configuration file is stored somewhere in your user folder: User/App Data/Roaming/CodeBlocks. Delete this folder and (at least i think) all settings will get lost.

about the segfault: Are you using the hello world program from wxSmith? Can you build it in release mode and try to run it?

some fresh rebuild log can also help..

greetings

Couldn't find the config file under the mentioned path (there seems to be no "App Data" or "Roaming" under Win7)

When I launch the "Hello World" equivalent of wxSmith in release mode it simply crashes immediately with windows telling me:
"xxx.exe has stopped working ..." and the infamous: "Windows can check online for a solution to the problem".

The same applies by the way for programs I have already written in the past (and that are supposed to work)

I could get it to work on my laptop (Win8) but on my win7 computer I'm still stuck.

This is the build log from the release compilation:

The folder has to be there, but he is hidden. You have to enable hidden files...
The path is: C:\User\Username\AppData\Roaming\CodeBlocks

with your wxWidgets problem... i can't help you... i think the right please for this question would be the wxWidgets Forum....

(the right dlls are in place or?)

greetings

Wow, finally I got it to run !

I recompiled wxWidgets and saw it moaning about conflicts with my "Stawberry" (Perl) installation. (It came with a scientific software package).
Therefore I took out: "C:\Program Files (x86)\CMake 2.8\bin;C:\strawberry\perl\bin;C:\strawberry\perl\site\bin;C:\strawberry\c\bin;"
from my "Path" variable, rebooted and reinstalled/recompiled wxWidgets and than:
Surprise ! It worked !

Thanks BlueHazzard and all those that may have given it a thought:
