[Inkscape-devel] Cannot build Inkscape with newest Mingw, devlibs36

13 Nov 2012


      XP SP3, 32 bit.
I had been happily building inkscape branch lp988601 on XP using a 
version of mingw
with gcc 4.6.2 and devlibs32.  Yesterday I tried to upgrade this build 
environment,
and while it builds to completion, the resulting inkscape does not run. 
Method
1.  mv ming mingw_save
2.  Download mingw-getinst-20120426.exe from sourceforge.  Run it, 
install C,C++ compilers and Mingw Devel.
     This resulted in gcc 4.7.2 and w32api and iconv installed (the 
latter two had to be installed separately
     last time.).
5.  bzr checkout --lightweight lp:inkscape-devlibs devlibs
     Move the folder to /c/progs/devlibs36.
6.  modify mingwenv.bat in inkscape directory to use 
/c/progs/devlibs36.
7.  g++ buildtool.cpp -o btool -fopenmp
     btool -version
     BuildTool v0.9.9multi
8.  bzr revert
     bzr update
     bzr revno (11707)
     btool clean
     btool  (builds to completion)
     inkscape\inkscape -> BOOOM!
        inkscape.exe has encountered a problem and needs to close.  We 
are sorry for the inconvenience.
9.  gdb
     file inkscape.exe inkscape.dbg
     run
Program received signal SIGSEGV, Segmentation fault.

10.  md5sum libglib*
18e88b04da123bf05b07ff60a4e96654 *libglib-2.0-0.dll
80c15c2a1c5d002ce72d2fa35212ad92 *libglibmm-2.4-1.dll
11. My understanding was that all of the dll's had to be recompiled to 
work with the newer compiler due to
a change in the calling convention, however many of the dll's in 
devlibs36 have the same md5sum's as do
the ones in devlibs32.  libglibmm isn't one of these, but libglib is, 
as is aspell and aspell-import.
Suggestions???
