DLL Stuff

News

• 2002-Aug-03: dllhelpers version 0.4.1 released. No big changes, mostly compatibility updates so that it will work with the upcoming gcc-3.x.x and gcc2-2.95.3 releases from the cygwin project. Also added two new (non-working) examples for fortran, which exercise (the as yet non-existant) capabilities of the g77 frontend: attribute tagging and auto_import. If you're looking for a way to contribute to gcc's fortran support, try looking into those missing capabilities.
  
  
• 2002-Feb-10: dllhelpers version 0.4.0 released. Adds four new examples using autotool-based dll building. One pair uses C and C++ to build DLLs with the old "stable", non-auto-import-capable libtool (autoconf-2.13, automake-1.4, libtool-1.4.2). the other pair uses C and C++ to build DLLs with the new "devel", auto-import-capable libtool (autoconf-2.52, automake-1.5, libtool-devel-20020202). This latter version is MUCH simpler.
  
  
• 2001-Oct-02: dllhelpers version 0.2.9 released. No longer use the -Wl,--enable-auto-import flag because newer cygwin binutils use --enable-auto-import by default. Also added a 'when_auto_import_fails' example, showing one way of dealing with the problem of multiword DATA exports from a DLL (for more information, see the ld documentation).
  
  
• 2001-Sep-19: dllhelpers version 0.2.8 released. No longer use the -Wl,--enable-auto-image-base flag (see README file inside the archive for more information). Also, added a c_and_c++ example, where two DLLs, one C-based and one C++based, are used by a single C++ file. (Demonstrates that (a) it can be done, and (b) two DLL's with the same image-base is not a problem).
  
  
• 2001-Sep-19: binutils.README added. This document was included in the cygwin binutils-20010802-1.tar.gz release, but went missing in the more recent package. I've updated it and added it here.
  
  
• 2001-Aug-04: Updated dllhelpers to use new auto-import feature of binutils-20010802.
• 2001-Jun-06: New package.

Notes

There are two packages here: dllhelpers is based on Mumit Khan's version and demonstrates how to build and use dlls with recent binutils/gcc on cygwin, in C, C++, and Fortran. hello demonstrates how to build and use dlls with recent versions of libtool/automake, and was created by Robert Collins based on the 'goat' book.
