Folks,
msvcrt has this in its spec file:
dlls/msvcrt/msvcrt.spec:@ forward -noimport _itoa ntdll._itoa
Yet at link time, I get an undefined reference error:
/home/dimi/dev/wine/wine/tools/winebuild/winebuild -fPIC -DSTRICT -o visual-mingw.exe.spec.c --exe visual-mingw.exe -m gui -r rsrc.res CList.o editor.o main.o process.o project.o winui.o -L/home/dimi/dev/wine/wine/dlls -ladvapi32 -lole32 -lcomdlg32 -lcomctl32 -lshell32 -luser32 -lgdi32 -lkernel32 -lmsvcrt gcc -D_WIN32_IE=0x0400 -c -o visual-mingw.exe.spec.o visual-mingw.exe.spec.c g++ -shared -Wl,-Bsymbolic visual-mingw.exe.spec.o CList.o editor.o main.o process.o project.o winui.o -o visual-mingw.exe.so -L/home/dimi/dev/wine/wine/library -lwine -lm project.o: In function `CProject::Open(char*, unsigned short)': project.o(.text+0x20e5): undefined reference to `_itoa' winui.o: In function `CStatusBar::WriteLong(long, int)': winui.o(.text+0x1d9a): undefined reference to `_itoa' winui.o: In function `CMessageBox::DisplayLong(long)': winui.o(.text+0x30a2): undefined reference to `_itoa'
However, if I also link in ntdll, it works:
/home/dimi/dev/wine/wine/tools/winebuild/winebuild -fPIC -DSTRICT -o visual-mingw.exe.spec.c --exe visual-mingw.exe -m gui -r rsrc.res CList.o editor.o main.o process.o project.o winui.o -L/home/dimi/dev/wine/wine/dlls -ladvapi32 -lole32 -lcomdlg32 -lcomctl32 -lshell32 -luser32 -lgdi32 -lkernel32 -lntdll -lmsvcrt gcc -D_WIN32_IE=0x0400 -c -o visual-mingw.exe.spec.o visual-mingw.exe.spec.c g++ -shared -Wl,-Bsymbolic visual-mingw.exe.spec.o CList.o editor.o main.o process.o project.o winui.o -o visual-mingw.exe.so -L/home/dimi/dev/wine/wine/library -lwine -lm [dimi@dimi src]$
Question is, is this correct? Do I need to link ntdll into the app as well?
Folks,
msvcrt has this in its spec file:
dlls/msvcrt/msvcrt.spec:@ forward -noimport _itoa ntdll._itoa
^^^^^^^^^ This is your problem. This tell winebuild to not export this function to winelib apps. The reason for this is probably to make pepole use the native unix version. Why I dont know.

In ntdll the export does not have the -noimport flag set so that is why it works

I wouldnt think so but Im not sure because whats the difference if people use it directly from ntdll or from msvcrt?

There is no native implementation of '_itoa'. 'itoa' yes, '_itoa', no.
However, in the past all Winelib applications would link to ntdll.dll and I think this is why all the functions that just forward to ntdll would have the -noimport flag. I guess that the goal was to avoid un unnecessary indirection.
Nowadays this may not be wise anymore since most Winelib applications link to msvcrt.dll, not ntdll.dll. This makes it necessary to modify the Makefiles to also link with ntdll.dll which seems a bit ugly. Might not be so bad though.
