Version: 1.14

Security Critical: No
Description:
iconv is a library for converting between different character encodings.
Used in Skia as a dependency of libpoppler, for PDF rasterization during
testing.
Local Modifications:
No changes to files from the upstream repository.
Platform-specific configuration files added to
third_party/iconv/config/windows:
config.h
iconv.h
localcharset.h
These files were created from the header templates based on instructions in:
http://www.codeproject.com/Articles/302012/How-to-Build-libiconv-with-Microsoft-Visual-Studio,
then kludging it to build. The process used to create them from release
sources are:
1. Download the libiconv-1.14 tarball from
http://www.gnu.org/software/libiconv/#downloading
2. Copy and rename these files:
(libiconv-1.14)/libcharset/include/localcharset.h.build.in
-> third_party/iconv/config/windows/localcharset.h
(libiconv-1.14)/include/iconv.h.build.in
-> third_party/iconv/config/windows/iconv.h
(libiconv-1.14)/config.h.in
-> third_party/iconv/config/windows/config.h
3. Modify localcharset.h as follows:
Replace
#if @HAVE_VISIBILITY@ && BUILDING_LIBCHARSET
#define LIBCHARSET_DLL_EXPORTED __attribute__((__visibility__("default")))
#else
#define LIBCHARSET_DLL_EXPORTED
#endif
with
#define LIBCHARSET_DLL_EXPORTED
4. Modify config.h as follows:
Delete line 30:
#undef EILSEQ
Change line 686 to:
#define ICONV_CONST const
5. Modify iconv.h as follows:
Replace
#if @HAVE_VISIBILITY@ && BUILDING_LIBICONV
#define LIBICONV_DLL_EXPORTED __attribute__((__visibility__("default")))
#else
#define LIBICONV_DLL_EXPORTED
#endif
with
#define LIBICONV_DLL_EXPORTED
Delete all references to @DLL_VARIABLE@ (find and replace with nothing).
Find and replace these:
@ICONV_CONST@ -> const
@USE_MBSTATE_T@ -> USE_MBSTATE_T
@BROKEN_WCHAR_H@ -> BROKEN_WCHAR_H
@HAVE_WCHAR_T@ -> HAVE_WCHAR_T
Note: if a dynamic library is needed for whatever reason,
LIBCHARSET_DLL_EXPORTED and LIBICONV_DLL_EXPORTED needs to be defined as
either __declspec(dllexport) or __declspec(dllimport).
Autogenerated files (consistent across platforms) added to
third_party/iconv/config:
aliases.h
canonical_dos.h
canonical.h
canonical_local.h
flags.h
These files were pulled from a release tarball.
