undefined reference to `LresultFromObject@12'  [SOLVED]

Do you have a question about makefiles, a compiler or IDE you are using and need to know how to set it up for wxWidgets or why it doesn't compile but other IDE's do ? Post your questions here.

undefined reference to `LresultFromObject@12'

Postby Alexandre GESP » Fri Mar 02, 2018 3:56 pm

Hello.
I have just download the new wxWidget 3.1.1, and compile the librairies (MONOLITHIC=1) with gcc (tdm-1) 5.1.0, the one include with codeblocks 17.10
There was no errors during the build.

When I try to compile my project, I have many linker errors:


Code: Select all

mingw32-g++.exe -LC:\WpdPack\lib -LC:\wx311\lib\gcc_lib -o "bin\Debug\Journal couleur.exe" obj\Debug\CodeBlocks\communs\MaLibrairie.o  "obj\Debug\CodeBlocks\Journal et croix full color\resource.res" -mthreads  -lwxmsw31ud -lwxpngd -lwxjpegd -lwxtiffd -lwxzlibd -lwxregexud -lwxexpatd -lkernel32 -luser32 -lgdi32 -lwinspool -lcomdlg32 -ladvapi32 -lshell32 -lole32 -loleaut32 -luuid -lcomctl32 -lwsock32 -lodbc32 -lversion -lshlwapi -mwindows

C:\wx311\lib\gcc_lib/libwxmsw31ud.a(monolib_window.o): In function `ZN8wxWindow16MSWHandleMessageEPljjl':
C:\wx311\build\msw/../../src/msw/window.cpp:3489: undefined reference to `LresultFromObject@12'
C:\wx311\build\msw/../../src/msw/window.cpp:3668: undefined reference to `GetThemeBackgroundContentRect@24'
and many mores...

I guess something has changed in librairies between 3.1.0 and 3.1.1, or that the librairies names has changed.
My 1st question: Can I know witch librairie I need to link just with the name of the missing call ?
2d question: Has anybody an encounter this error of missing reference

These are Windows functions. When this happens, Google "msdn LresultFromObject" and it will take you to the documentation, which will tell you that this function is in "Oleacc.lib".

Repeat until all Windows references are found.
Use the source, Luke!

Hi,
Why did you build MONOLITHIC library? There is no gain vs. multiple libraries - just more headache.
Library name(s) are not changed - just the suffix changed from 3.0 to 3.1.

Try to re-build wx with multiple libraries and rebuild the application. Or try to build the minimal sample and see if it runs.

Thank you.

To doublemax: Thanks, its works. I do have tried the minimum sample given with codeblocks 17.12, but it does not include the two missing librairies lUxTheme and oleacc:

Code: Select all

mingw32-g++.exe -LC:\wx311\lib\gcc_lib -o bin\Debug\test.exe  obj\Debug\testApp.o obj\Debug\testMain.o obj\Debug\resource.res -mthreads -m32  -lwxmsw31ud -lwxpngd -lwxjpegd -lwxtiffd -lwxzlibd -lkernel32 -luser32 -lgdi32 -lwinspool -lcomdlg32 -ladvapi32 -lshell32 -lole32 -loleaut32 -luuid -lcomctl32 -lwsock32 -lodbc32 -lshlwapi -lversion -loleacc -lUxTheme -mwindows
Output file is bin\Debug\test.exe with size 80.84 MB


To ONEEYEMAN: My fault: When I was young and hadesome, many, many years ago, I started with a MONOLITHIC=1 switch just to avoid searching witch librairie to include in project, and now that I have dozen of active projects, I will be complicated to modify all my cbp project file to use MONOLITHIC=0 build... Lazy one day, lazy forever....
