Title: WxWidgets Project in Code::Blocks - ld.exe cannot find -lwxmsw30d
Post by: DarthVega7 on February 20, 2015, 05:42:52 pm
Hello,

I'm getting the error:  ld.exe cannot find -lwxmsw30d when I try to build and run a wxwidgets project in code::blocks.

Please help?

Thanks,

Post a build log or I will ignore you.

Does the library exist inside your folder C:\SourceCode\Libraries\wxWidgets3.0\lib\gcc_dll ?
If not, then you need to change the project options or you need to build the missing library.

I'm sorry, I'm such a newb... How do I build the missing library?

Does wxmsw30ud library exist?
You do know that unicode is required with wxWidgets 3.0 unless you are a expert.

IIRC, "BUILD=debug" is needed for wxWidgets debug version.

Whenever I try to build the library it gives me this:

I suggest reading this site in case you can find the cause on it; also your problem would be more on target on that site.

I have gotten that error before; but, I am not sure why.

I did find that this fixes some weired errors.

Instead of
Code
mingw32-make.exe -f makefile.gcc BUILD=release SHARED=1 MONOLITHIC=1 UNICODE=1 CXXFLAGS=-fno-keep-in
line-dllexport
I add SHELL=CMD.exe so it becomes
Code
mingw32-make.exe -f makefile.gcc SHELL=CMD.exe BUILD=release SHARED=1 MONOLITHIC=1 UNICODE=1 CXXFLAGS=-fno-keep-in
line-dllexport

Note I do NOT have to do that myself because I build wxWidgets by setting the PATH system variable to a valid value before doing the make command.

Edit: Valid value means one that only contains the MinGW GCC and the 2 to 4 required Windows folders.

Edit2: You might wish to try this and see if the error goes away.

Code
SET PATH=C:\MinGW\bin;%PATH%
mingw32-make.exe -f makefile.gcc BUILD=release SHARED=1 MONOLITHIC=1 UNICODE=1 CXXFLAGS=-fno-keep-inline-dllexport
