I use Cygwin and MSVC 2008 express. The build fails in instsetoo_native because the files Microsoft.VC80.CRT.manifest, msvcp80.dll, and msvcr80.dll are missing. Such should be detected at the start of building not at the end. So this files should be fetched in the beginning or at least it should be checked, whether they are available.
@Regina Really new effect in Master or also observed in older LibO versions? With what source version did that problem start?
I don't know, whether this problem occurs in older versions. Before LibreOffice had got a single repository "core" I had used the old OOo way to build, without autogen.sh, and I had copied _all_ files to external, whether there are needed or not.
It's WORKSFORME. See http://opengrok.libreoffice.org/xref/core/post_download.in#37 which trigger ./oowintool --msvc-copy-dlls.
This issue is about msvcp80 not about msvcp90.
Sorry :( Reopening this.
LO 3.4.5 cannot be built on Windows because mozilla libs require msvcp80.dll. If I add options --disable-build-mozilla and --disable-mozilla then this problem disappears.
