building 32bits library always fails

El_isra · Post by **El_isra** » Sun Jul 18, 2021 12:09 am

it fails on this line: without error output, if I re-execute the command it eventually fails with an error mesage

..\..\include/wx/geometry.h:634:21: note: because 'wxRect2DDouble' has user-provided 'wxRect2DDouble& wxRect2DDouble::op
erator=(const wxRect2DDouble&)'
  634 |     wxRect2DDouble& operator = (const wxRect2DDouble& rect);
      |                     ^~~~~~~~

I'm testing again to post error message here...
the command i'm testing this time is:

Code: Select all

%min32%\mingw32-make -j4 -f makefile.gcc CXXFLAGS="-std=gnu++11" BUILD=debug UNICODE=1 SHARED=0 MONOLITHIC=1

obviously i used setup_h before...

Currently testing on TDM-GCC 32 bits because codeblocks default compiler can't build any 32bit program, even small projects like this: https://github.com/israpps/DiagBox

finally got that shitty error message:

What wxWidgets version are you building?
Which GCC version are you using?
Is it an MinGW64 or an mingw.org based GCC compiler?
You do know that using Monolithic build is normally more likely to be broken, right?

1) latest stable release

2) gcc versión 10.3.0 (tdm-1)

3) how do i check that?

4) i know, irrelevant however, since both of them fail on the same error

So, you are using a very old stable version of unknown number!

Apply the patch and see it it fixes the problem.

Which compiler did you install?
Was it from here?

wxWidgets-3.0.5

You might wish to try 3.0.5-1; but, I have no idea what was fixed in the dash 1; so, you need to apply the patch I have already posted.
for 3.0.5 .

Can't remember atm.
i got the link from a code::blocks tutorial...
i'll see if i can find more....

the folder has some markdown files, inside one i found:

Code: Select all

distributed by the MinGW.org project.

[/quote]

Changing from Monolithic to non Monolithic build requires the build folder to be deleted because cleaning is not enough to get rid of all the problems.
So, if you have changed Monolithic value, you need to delete the wxWidgets files and start with a new wxWidgets extraction folder.

Hi,
Also, keep in mind that unless you plan to work on the CodeBlocks itself, you better not use MONOLITHIC build.

Thank you.

El_isra · Post by **El_isra** » Mon Jul 19, 2021 8:27 pm

I always erase and decompress again the src after a failure

ONEEYEMAN · Post by **ONEEYEMAN** » Mon Jul 19, 2021 9:42 pm

Hi,
So you are doing a rebuild on a CLEAN sources when you change the configuration?

Did you try to apply Tim's patch and rebuild?

Also, it would be nice to know what version of GCC/MinGW you are using and where did you get it from.

Thank you.

El_isra · Post by **El_isra** » Mon Jul 19, 2021 10:34 pm

the issue also happens on latest wxwidgets...
so i'm guessing it's compilers faul..
if any of you can recommend any toolchain capable of building 32bits wxwidgets programs i wil be very gratefull!

ONEEYEMAN · Post by **ONEEYEMAN** » Mon Jul 19, 2021 11:51 pm

Hi,
What is your version of GCC and where did you get it?
What was you build command for the "master"?

Thank you.
