Help Please!
I am trying to compile kde 4.6 on 32bits windows 7 following the instruction below:
http://techbase.kde.org/Getting_Started ... ows/emerge

Below is the commands:
cd emerge && git checkout kde-4.6
I use MinGW compiler
emerge qt worked successfully, but when I run the command below, I got linking error:
emerge kdelibs

"undefined reference to `_imp__TzSpecificLocalTimeToSystemTime@12'"

Here is the log:
...

I have beening search online but can not figure out how to fix it. I really appreciate any suggestion.

Thanks,

Hi

I've spent lots and lots of time trying to fight this thing.
As it appeared, this is the faulty MinGW package. The thing is you have to regenerate libkernel32.a from your kernel32.dll or use the one that should be shipped with emerge's MinGW. here are the instructions:

I. First way
To regenerate libkernel32.a from your kernel32.dll you have to:
1) enter in your console window:

Code: Select all

pexports C:\Windows\System32\kernel32.dll > %kderoot%\lib\kernel32.def

2) enter in your console window:

Code: Select all

dlltool -d %KDEROOT%\lib\kernel32.def -l %KDEROOT%\mingw\i686-w64-mingw32\lib\libkernel32.a

Note: %KDEROOT% stands for your kderoot directory, you might want to replace it with your own path.
Note: the exact path where to place your newly generated .a file can be found by simple windows search for libkernel32.a file.

II. The Second, and maybe, The Proper Way
Install the emerge package, that conbtains needed patch and required .a file in the tarball and solves this problem automagically
1) Enter in your console window:

Code: Select all

emerge --unmerge %your_mingw%

This would remove old and broken version of mingw that you use from KDEROOT (the exact name of %your_mingw% package you can find with 'emerge --print-installed' command). If you happen to use your own mingw version, that you've sinstalled separately and that didn't ship with emerge you'd better remove it from your PATH and follow the next step
2) install the right compiler package:

Code: Select all

emerge mingw-w32

This will install the right compiler package and solve your problem. Mind that if you will use 64bit Windows you'll have to install 'mingw-w64' package, that has no such a problem and thus doesn't provide you with regenerated libkernel32.a file

So now you should be ok. Ask if something isn't clear to you

Hi Kraplax,

Thank you very much for your help. That fixed the issue. You saved my day

Best,
Michael
