[Adobe-source-devel] Newbie question on GIL

[Haroon K. <har...@gm...>]

Hi,
Today is my first day of using GIL, and I was trying to compile and
link the jpeg, png, and tiff libraries for a test program based on the
sample program provided on the website. I kept getting linker errors,
e.g.

...
1>hello_world.obj : error LNK2001: unresolved external symbol "int
__cdecl jpeg_read_header(struct jpeg_decompress_struct *,unsigned
char)" (?jpeg_read_header@@YAHPAUjpeg_decompress_struct@@E@Z)
1>hello_world.obj : error LNK2001: unresolved external symbol "void
__cdecl jpeg_stdio_src(struct jpeg_decompress_struct *,struct _iobuf
*)" (?jpeg_stdio_src@@YAXPAUjpeg_decompress_struct@@PAU_i
....

until I went and edited the GIL header files and enclosed the #includ
files for the jpeg, tiff, and png files with extern "C". Is this the
correct way of doing this? or is there some build option in the
libraries that I need to set.  I've already downloaded and created the
static libraries for jpeg, tiff and png libs.

I'm using Windows XP, and MSVC8.


Thanks, Haroon
