Can't build a nodejs addon that links to IM x86 Windows

[josh3736]

Trying to build node-imagemagick-native on a Windows 7 x64 box, targeting x86.

ImageMagick's definition of ssize_t conflicts with libuv's definition.

magick-baseconfig.h

Code: Select all

#if !defined(ssize_t) && !defined(__MINGW32__) && !defined(__MINGW64__)
#if defined(_WIN64) 
typedef __int64 ssize_t;
#else
typedef long ssize_t;
#endif
#endif

uv-win.h

Code: Select all

#if !defined(_SSIZE_T_) && !defined(_SSIZE_T_DEFINED)
typedef intptr_t ssize_t;
# define _SSIZE_T_
# define _SSIZE_T_DEFINED
#endif

Compiler complains

magick-baseconfig.h(182): error C2371: 'ssize_t' : redefinition; different basic types

For kicks and giggles, I tried changing long to intptr_t and got

imagemagick.obj : error LNK2001: unresolved external symbol "public: __thiscall
Magick::Geometry::Geometry(unsigned int,unsigned int,int,int,bool,bool)" (??0G eometry@Magick@@QAE@IIHH_N0@Z) [D:\Users\Josh\Documents\js\node-imagemagick-nat ive\build\imagemagick.vcxproj]

Any ideas how I can get ImageMagick working with node x86?

Add

• #define _SSIZE_T 1

to magick-baseconfig.h.

Adding

Code: Select all

#define _SSIZE_T_ 1

to magick-baseconfig.h gives me:

Just warnings, it should work.

[josh3736]

There is an error in there:

magick-baseconfig.h(183): error C2371: 'ssize_t' : redefinition; different basic types

[magick]

Ok, try commenting out the ssize_t definition in magick-baseconfig.h. Does that work?

[josh3736]

Nope:

[magick]

Ok, try defining _SSIZE_T_DEFINED to 1 in magick-baseconfig.h. If that does not work, post a bug report to NodeJS. Maybe they have a suggestion.

[josh3736]

Issue resolved.

Turns out this was an issue with the module's build configuration and the order of includes.

Thanks for your help.
