mingw IM6.8.6-9 IsWow64Process undefined reference

[mhck]

I found an old post saying this was fixed a while back. However, when I compile IM 6.8.6-9 I first get a warning:

Code: Select all

magick/nt-base.c: In function 'NTIs64BitPlatform':
magick/nt-base.c:1021:3: warning: implicit declaration of function 'IsWow64Process' [-Wimplicit-function-declaration]
   return(IsWow64Process(GetCurrentProcess(), &is64) && is64);
   ^

and then an error:

Code: Select all

CCLD     magick/libMagickCore-6.Q16.la
magick\\.libs\\magick_libMagickCore_6_Q16_la-nt-base.o: In function `NTIs64BitPlatform':
C:\msys\1.0\local\src\ImageMagick-6.8.6-9/magick/nt-base.c:1021: undefined reference to `IsWow64Process'
collect2.exe: error: ld returned 1 exit status

I checked to make sure IsWow64Process exists:

Code: Select all

user@W7PC /mingw/include
$ grep -r -i "IsWow64Process" *.h
winbase.h:WINBASEAPI BOOL WINAPI IsWow64Process(HANDLE,PBOOL);

user@W7PC /mingw/lib
$ grep -r -i "IsWow64Process" *.a
Binary file libkernel32.a matches

I apologize in advance for being a bit of a mingw n00b. Thanks.


To follow up... I performed a 'make clean', './configure --without-perl', and 'make'
This time, the error changed:

Code: Select all

  CCLD     utilities/animate.exe

[magick]

We compiled ImageMagick under MinGW without complaint. We're not sure why its failing for you.

[mhck]

The IsWow64Process undefined reference error came from restarting the MSYS window and not re-exporting CPPFLAGS and LDFLAGS, i.e.

Code: Select all

export CPPFLAGS="-Ic:/gnuwin32/include"
export LDFLAGS="-Lc:/gnuwin32/lib"

Once I exported, I had to 'make distclean', run './configure --without-perl', and then 'make'.


I'm still trying to figure out the undefined references when building utilities/animate.com. Prior to, I get these warnings:

Code: Select all

Thanks again for any help!

Try ./configure --enable-shared. Does not work for you?

[mhck]

It does not. I get the same errors with or without './configure --enable-shared'.
