Can't build the new wxWidgets. What should i do?

Question

I'm feeling a bit dumb, but i can't build the new wxWidgets. I want to use codelite + mingw + wxWidgets, so i download the latest releases:

CodeLite 9.1.3 (http://downloads.codelite.org/downloads.php?windows_weekly_64)

The installer make me download the TDM-GCC-64 setup and install it.

Then i downloaded wxWidgets-3.1.0 (https://github.com/wxWidgets/wxWidgets/releases/download/v3.1.0/wxMSW-3.1.0-Setup.exe)

Codelite detected the the compiler, now i should build the wxWidgets, but the pages i've googled for (wxW wiki, codelite docs, etc) refers to folders and files that does'nt exist. Everything is installed in the default folders, and i'm not a PC noob, while perhaps too used to environments like C++Builder etc.

What should i do now?

UPDATE

I'm sorry i'm not able to be clear. Let me try again with the output:

I may be wrong, but seems to me that these two lines

if not exist ..\..\lib\gcc_dll mkdir ..\..\lib\gcc_dll
if not exist ..\..\lib\gcc_dll\mswu\wx\setup.h copy ..\..\include\wx\msw\setup.h ..\..\lib\gcc_dll\mswu\wx\setup.h

shows that there's a problem.

Now, i've made the directory myself and copied the setup.h in. At my home it was'nt still building, but i can't recall why, while right now, at office, it start building, but ended with this:

So, we're still not building the wxWidgets.

The file is there, so i don't know what's the problem...

Answer 1

The installer make me download the TDM-GCC-64 setup and install it.

CodeLite suggests...

What should i do now?

Build wxWidgets like this:

• Download wxWidgets sources https://github.com/wxWidgets/wxWidgets/releases/download/v3.1.0/wxWidgets-3.1.0.7z

• Build wxWidgets as described on CodeLite's wiki page

• Install a decent compiler (Recommended: MinGW TDM-GCC 5.X series)
• When you open the CMD to build, type this: set path=\path\to\MinGW\bin;%path%

After you have built wxWidgets, you need to set 2 environment variables in CodeLite from: (Settings->Environment variables):

WXCFG=gcc_dll\mswu WXWIN=\path\to\wxWidgets

If you attempt to build the Debug configuration of your project in CodeLite, you should do ONE of the following:

Build a debug version of wxWidgets (this is what CodeLite will search)

OR

Remove --debug flag from the compiler and linker options:

1. Project Settings->Compiler->C++ Compiler Options, and remove the part that says --debug=yes or just --debug
2. Project Settings->Linker->Linker options, and remove the part that says --debug=yes or just --debug

EDIT: Update CodeLite's wiki page link

EDIT2: Added PATH instructions to the answer

EDIT3: Added instructions on how to set the environment variables WXCFG and WXWIN

Answer 2

As for today, the build forget to make two directories. The solution is to make them yourself before building.

So my solution is to go to your wxWidget folder and type:

C:\wxWidgets-3.1.0>mkdir lib\gcc_dll\mswu\wx\
C:\wxWidgets-3.1.0>copy include\wx\msw\setup.h lib\gcc_dll\mswu\wx\setup.h

Answer 3

There is a bug in makefile.gcc when using parallel make (i.e. with -j8). A workaround is to do

mingw32-make <all the same options> setup_h

first followed by the normal make command. Another alternative is to use configure-based build which doesn't suffer from this problem.

The compilation problem with _hypot() is due to a compiler bug and we've tried to work around it in this commit, but apparently it wasn't enough. You should report the problem with more details, including the version of the compiler you use and the options passed to make.

Answer 4

I had a similar problem using this command

mingw32-make -j8 -f Makefile.gcc SHARED=1 UNICODE=1 BUILD=release VENDOR=cl CXXFLAGS="-fno-keep-inline-dllexport -std=c++11" MONOLITHIC=1

Problem is -j8 which considers number of physical processors before the build process commences.

Try -jN (replace N to value of NUMBER_OF_PROCESSORS)

mingw32-make looks at actual number of physical processors, hyper-threaded or virtual processors are not consider. If however your machine has less than assigned physical processors, it causes error.

You can also try putting just -j into the make arguments field. That tells Make to spawn as many compile processes as it can if you have enough RAM and CPU to handle that, it should be faster than a single compile.

I successfully tried with -j4 on i7 which has 4 physical processors.

( Note : when hyper-threading is turned on i7 shows 8 virtual processors )

Something similar is mentioned by Orient here

A better explain by Brendan Shanks is mentioned here.
