Re: [gdal-dev] fail to build gdal 1.9 with minGW

[chenliang wang]

Thanks for your reply. I have tried 'make clean' and then rebuild GDAL. 
And I have also modified GNUmakefile ,replaed '${GDAL_ROOTs}' for '.' 
and then 'make clean' and rebuild it again. Unfortunately, I failed 
again. I use command ' ./configure --prefix=..... ' Should I need to add 
option '--host=mingw32' or '--without-libtool'?

hi:
I failed to build gdal 1.9 with minGW. I modified 'cpl_multiproc.h' with
the patch.But there are still errors with build:cpl_multiproc.cpp:73:
undefined reference to `CPLCreateOrAcquireMutex' .Pls help me out.Thanks!

#if defined(WIN32)&&  !defined(CPL_MULTIPROC_STUB)
# define CPL_MULTIPROC_WIN32
/* MinGW can have pthread support, so disable it to avoid issues */
/* in cpl_multiproc.cpp */
# undef CPL_MULTIPROC_PTHREAD
#endif

Did you 'make clean' after applying the patch and before rebuilding GDAL ? The
reporter of https://trac.osgeo.org/gdal/ticket/4430 confirmed that the above
patch fixed building for him.
