Hi! As discussed earlier[1], there are problems with preloading import libraries when using Microsoft Visual C/C++. This series is a polished version of the previously posted rough cut. However, the first two patches are largely unrelated to the topic, but they help visualize what the meat in the third patch is all about. So, I guess they are related after all, which is why I posted them as a series. :-)
This version will not create an @INIT@ symbol in the preloader table unless one is neaded, i.e. an actual data import item is needed to trigger the creation of the lt_syminit function and the fake @INIT@ symbol providing its address. Also, the "cost" in preopen.c is neglectable, as the loops from the proof of concept first draft are gone. With: .../configure \ CC="`pwd`/build-aux/compile cl -nologo" \ CFLAGS="-MD -Zi -EHsc" \ CXX="`pwd`/build-aux/compile cl -nologo" \ CXXFLAGS="-MD -Zi -EHsc" \ NM="dumpbin -symbols -headers" \ LD=link \ STRIP=: \ AR="`pwd`/build-aux/ar-lib lib" \ RANLIB=: \ F77=no FC=no GCJ=no from MSYS with Microsoft Visual C/C++ 2010 on $PATH, I get: ## ------------- ## ## Test results. ## ## ------------- ## 139 tests behaved as expected. 29 tests were skipped. So, all failures are fixed. The testsuite is also clean on Cygwin and MinGW (which makes me confident that the added special caseing doesn't mess up systems that don't make use of them). Is it unintrusive enough? Ok to push? (confession: I did a few last minute trivial changes just before posting which (drumroll) shouldn't affect things. Anyway, the testsuite is part way through with thouse changes and the patch has been somewhat exercised so it is looking good, but I will naturally post a followup if anything untoward surfaces) Cheers, Peter [1] http://lists.gnu.org/archive/html/libtool-patches/2012-10/msg00055.html
