[solved] codeblocks 13.12 & wxWidgets 3.0 config, ld.exe cannot find -lwxmsw30u?

<< < (2/7) > >>

stahta01:
You have both

--- Code: ----IC:\etc\wxWidgets-3.0.0\lib\gcc_dll\mswu
-IC:\etc\wxWidgets-3.0.0\lib\gcc_dll\mswud

--- End code ---

Get rid of the one that does NOT exist.

You say you only built debug; is there a logical reason you are doing that instead of both?

Edit: You need to define "__WXDEBUG__" when using the wxWidgets debug library.

My build log on doing wxWidgets 3.0 Debug build Multilib (removed PCH precompile)
(Multilib is the opposite choose of Monolithic build)

Where mine says "gcc48_dll" yours should say "gcc_dll"

Where mine says "-lwxmsw30ud_core -lwxbase30ud" yours should say "-lwxmsw30ud".

Where mine says "testwx48" yours should say "aaa".

My wxWidgets base folder: "C:\wxMSW-3.0\wxWidgets-3.0.0"

Note: You build need not have "-include wx_pch.h" in it.

Note: This option is NOT needed "-Wmissing-include-dirs"

Note: Yours might not have "--use-temp-file" in it; I added that to test something long ago.

Change "wxmsw30u" to "wxmsw30ud" in "Linker Settings" under "Link Libraries"

Note: These NOT needed "-Wfatal-errors -Wno-unused-local-typedefs -Wno-attributes"

thanks, stahta01, it worked!
your answer helped me!

ps: other newbies who meet same trouble like me plz check the attachment file, by check on the red colored area, it will be remove the error!

Hi,
i've same problem but I don't think that problem is only the __WXDEBUG__ option (checked or unchecked);
if i check this advanced option simply the problem becomes "... ld.exe cannot find -lwxmsw30ud" but in my environment
issue remains.

My build log is:

--- Code: ---mingw32-g++.exe -pipe -mthreads -D__GNUWIN32__ -D__WXMSW__ -DWXUSINGDLL -DwxUSE_UNICODE -Wall -g -D__WXDEBUG__ -IC:\SourceCode\Libraries\wxWidgets3.0\include -IC:\SourceCode\Libraries\wxWidgets3.0\lib\gcc_dll\mswud -c C:\Users\W7onSSD\Documents\C_PROJECTS\monitor\monitorApp.cpp -o obj\Debug\monitorApp.o

collect2.exe: error: ld returned 1 exit status
Process terminated with status 1 (0 minute(s), 4 second(s))
1 error(s), 0 warning(s) (0 minute(s), 4 second(s))

--- End code ---

Problem (for me) is that wizard search in wxWidgets3.0\lib\gcc_dll\mswu or wxWidgets3.0\lib\gcc_dll\mswu when it doesn't exist. I solved changing $(#wx)\lib\gcc_dll\mswud to $(#wx)\lib\gcc48_dll\mswud in searching directory for compiler and resource compiler tabs and changing $(#wx)\lib\gcc_dll to $(#wx)\lib\gcc48_dll in linker tab.

What do you think ?

stahta01:
That is one of the correct solution when linking against one of wxPack binary Libraries.

Building against wxWidgets 3.0 binary Libraries has a similar solution.
