[Mingw-users] DLLs dragging in LIBSTDC++-6.DLL and LIBGCC_S_DW2-1.DLL?

[Bill J. <ja...@pa...>]

I'm building JCC (from http://lucene.apache.org/pylucene/) with MinGW on
64-bit Windows 7 (though everything I'm doing and using is 32-bit), and
running into this problem with the generated JCC DLL (called "_jcc.pyd"):

A little googling tells me that this comes from allocating memory in one
libc, and freeing it in a different one (different heaps).

I see that _jcc.pyd is linked against LIBSTDC++-6.DLL and
LIBGCC_S_DW2-1.DLL, and wonder if that could be the problem.  Is there a
way to eliminate those DLLs from my link?  Here's the link line I'm
using, somewhat elided to remove the long list of object files:

$ C:\MinGW\bin\g++.exe -mno-cygwin -shared -s build\temp.win32-2.7\Release\jcc\sources\jcc.o [...] build\temp.win32-2.7\Release\_jcc\java\util\iterator.o build\temp.win32-2.7\Release\jcc\sources\_jcc.def -Lc:\Python27\libs -Lc:\Python27\PCbuild -lpython27 -lmsvcr90 -o build\lib.win32-2.7\jcc\_jcc.pyd "-LC:\Program Files (x86)\Java\jdk1.6.0_22/lib" -ljvm -Wl,--enable-auto-import -Wl,-S

And here's a typical compile step:

$ C:\MinGW\bin\gcc.exe -mno-cygwin -mdll -O -Wall -D_java_generics -DJCC_VER="2.6" "-IC:\Program Files (x86)\Java\jdk1.6.0_22/include" "-IC:\Program Files (x86)\Java\jdk1.6.0_22/include/win32" -I_jcc -Ijcc/sources -Ic:\Python27\include -Ic:\Python27\PC -c _jcc\java\util\Enumeration.cpp -o build\temp.win32-2.7\Release\_jcc\java\util\enumeration.o -DPYTHON -fno-strict-aliasing -Wno-write-strings
