Compile libtiff 3.8.2 with mingw

Hi,

I get source from libtiff 3.8.2 from gnuwin32 but cannot get the libtiff3.dll.

First I edit the Makefile.mingw to enable ZIP and JPEG compression (from the tiff-3.8.2 directory). Then I launch a "make -f makefile.mingw" to prepare the makefile in all subdir. After I launch make.
And it failed to compile the tool bmp2tiff.exe complaining about missing:
gcc.exe: ../libtiff/.libs/libtiff.dll.a: No such file or directory

I detect that libtiff.def were not made in .libs.
The command line shown is:

dlltool.exe --output-def=libtiff.def tif_aux.o tif_close.o tif_codec.o tif_color.o tif_compress.o tif_dir.o tif_dirinfo.o tif_dirread.o tif_dirwrite.o tif_dumpmode.o tif_error.o tif_extension.o tif_fax3.o tif_fax3sm.o tif_flush.o tif_getimage.o tif_jpeg.o tif_luv.o tif_lzw.o tif_next.o tif_ojpeg.o tif_open.o tif_packbits.o tif_pixarlog.o tif_predict.o tif_print.o tif_read.o tif_strip.o tif_swab.o tif_thunder.o tif_tile.o tif_unix.o tif_version.o tif_warning.o tif_write.o tif_zip.o libtiff-dllversion.o libtiff-dll-res.o

If I launch this manually, libtiff.def is done but it seems to be empty:
; c:\mingw\bin\dlltool.exe --output-def=libtiff.def tif_aux.o tif_close.o tif_codec.o tif_color.o tif_compress.o tif_dir.o tif_dirinfo.o tif_dirread.o tif_dirwrite.o tif_dumpmode.o tif_error.o tif_extension.o tif_fax3.o tif_fax3sm.o tif_flush.o tif_getimage.o tif_jpeg.o tif_luv.o tif_lzw.o tif_next.o tif_ojpeg.o tif_open.o tif_packbits.o tif_pixarlog.o tif_predict.o tif_print.o tif_read.o tif_strip.o tif_swab.o tif_thunder.o tif_tile.o tif_unix.o tif_version.o tif_warning.o tif_write.o tif_zip.o libtiff-dllversion.o libtiff-dll-res.o
EXPORTS
DllGetVersion @ 1 ;

Then I can launch command:
gcc.exe -Wl,--out-implib=libtiff.dll.a -Wl,-s -Wl,-e,_DllMainCRTStartup@12 -shared -Wl,-s -Wl,--enable-auto-import -Wl,--enable-runtime-pseudo-reloc -Wl,--enable-stdcall-fixup -Wl,--add-stdcall-alias -Wl,--enable-auto-image-base -Wl,--major-image-version=1 -Wl,--minor-image-version=0 -o libtiff3.dll -Wl,--whole-archive tif_aux.o tif_close.o tif_codec.o tif_color.o tif_compress.o tif_dir.o tif_dirinfo.o tif_dirread.o tif_dirwrite.o tif_dumpmode.o tif_error.o tif_extension.o tif_fax3.o tif_fax3sm.o tif_flush.o tif_getimage.o tif_jpeg.o tif_luv.o tif_lzw.o tif_next.o tif_ojpeg.o tif_open.o tif_packbits.o tif_pixarlog.o tif_predict.o tif_print.o tif_read.o tif_strip.o tif_swab.o tif_thunder.o tif_tile.o tif_unix.o tif_version.o tif_warning.o tif_write.o tif_zip.o libtiff-dllversion.o libtiff-dll-res.o -Wl,--no-whole-archive -Wl,--no-whole-archive -Wl,--major-image-version=3 -Wl,--minor-image-version=8 -L/c/progra~1/GnuWin32/lib -L/c/progra~1/GnuWin32/lib -L/c/progra~1/GnuWin32/lib -Lc:/Progra~1/GnuWin32/lib -lgw32c -liberty -lintl -liconv -lwsock32 -lole32 -luuid -lmsvcp60 -ljpeg -lz -Wl,--exclude-libs=ALL libtiff.def

But It complain about a lot of missing reference:

Creating library file: libtiff.dll.a
tif_aux.o(.text+0x60): In function TIFFCheckMalloc': c:/Program Files/GnuWin32/src/tiff/3.8.2/tiff-3.8.2/libtiff/../../tiff-3.8.2-src/libtiff/tif_aux.c:49: undefined reference to_imp__TIFFErrorExt'

...

I simply compare with what happen in libjpeg at this point. Here are the command line used:

dlltool.exe --export-all-symbols --output-def=jpeg.def jcapimin.o jcapistd.o jctrans.o jcparam.o jdatadst.o jcinit.o jcmaster.o jcmarker.o jcmainct.o jcprepct.o jccoefct.o jccolor.o jcsample.o jchuff.o jcphuff.o jcdctmgr.o jfdctfst.o jfdctflt.o jfdctint.o jdapimin.o jdapistd.o jdtrans.o jdatasrc.o jdmaster.o jdinput.o jdmarker.o jdhuff.o jdphuff.o jdmainct.o jdcoefct.o jdpostct.o jddctmgr.o jidctfst.o jidctflt.o jidctint.o jidctred.o jdsample.o jdcolor.o jquant1.o jquant2.o jdmerge.o jcomapi.o jutils.o jerror.o jmemmgr.o jmemnobs.o jpeg-dllversion.o

And

gcc.exe -Wl,--out-implib=libjpeg.dll.a -Wl,--export-all-symbols -Wl,-s -Wl,-e,_DllMainCRTStartup@12 -shared -Wl,-s -Wl,--enable-auto-import -Wl,--enable-runtime-pseudo-reloc -Wl,--enable-stdcall-fixup -Wl,--add-stdcall-alias -Wl,--enable-auto-image-base -Wl,--major-image-version=6 -Wl,--minor-image-version=2 -o jpeg62.dll -Wl,--whole-archive jcapimin.o jcapistd.o jctrans.o jcparam.o jdatadst.o jcinit.o jcmaster.o jcmarker.o jcmainct.o jcprepct.o jccoefct.o jccolor.o jcsample.o jchuff.o jcphuff.o jcdctmgr.o jfdctfst.o jfdctflt.o jfdctint.o jdapimin.o jdapistd.o jdtrans.o jdatasrc.o jdmaster.o jdinput.o jdmarker.o jdhuff.o jdphuff.o jdmainct.o jdcoefct.o jdpostct.o jddctmgr.o jidctfst.o jidctflt.o jidctint.o jidctred.o jdsample.o jdcolor.o jquant1.o jquant2.o jdmerge.o jcomapi.o jutils.o jerror.o jmemmgr.o jmemnobs.o jpeg-dllversion.o -Wl,--no-whole-archive -Wl,--no-whole-archive -Lc:/Progra~1/GnuWin32/lib -lgw32c -liberty -lintl -liconv -lwsock32 -lole32 -luuid -lmsvcp60 -Wl,--exclude-libs=ALL jpeg.def

The main difference I see is in the parameter --export-all-symbols. And the jpeg.def contains much more infos.

If somebody can help me.
Thanks in advance
