installing libiconv library

krishi has asked for the wisdom of the Perl Monks concerning the following question:

Hi there,
I want to install Prima module.
For that I need to install a host of libraries like jpeg,zlib, libiconv,glib,etc.
But I am not able to install libiconv-1.11.
I downloaded it from www.sunfreeware.com and I have also installed gettext which is necessary for libiconv.
Earlier, it was showing an error that wchar_c99.h was not found.
Then I got the header file from Koders website and copied it into the /usr/include/iso/ path.
Now it is showing the following error:

/usr/include/iso/wchar_c99.h:66: error: conflicting types for '_RESTRICT_KYWD'
/usr/include/iso/wchar_c99.h:66: error: previous definition of '_RESTRICT_KYWD' was here
/usr/include/iso/wchar_c99.h:69: error: redefinition of parameter '_RESTRICT_KYWD'
/usr/include/iso/wchar_c99.h:68: error: previous definition of '_RESTRICT_KYWD' was here
/usr/include/iso/wchar_c99.h:72: error: conflicting types for '_RESTRICT_KYWD'
/usr/include/iso/wchar_c99.h:71: error: previous definition of '_RESTRICT_KYWD' was here
*** Error code 1
make: Fatal error: Command failed for target `preloadable_libiconv_solaris.so'
Current working directory /export/home/NetDeposit/dps/libiconv-1.11/lib
*** Error code 1
make: Fatal error: Command failed for target `all'
Can anybody help me with it?
Thanks in advance,
Krishi.

Looking at the file in question, it appears that all the errors are stemming from function signatures (in which multiple arguments have the same dummy argument name). My C is a little rusty, but as I remember, you can omit the dummy argument names on declarations. This would give you (lines 63-80): ... #if defined(_STDC_C99) \|\| \ (!defined(_STRICT_STDC) && !defined(__XOPEN_OR_POSIX)) \|\| \ defined(_XPG6) \|\| defined(__EXTENSIONS__) extern int vfwscanf(__FILE , const wchar_t , __va_list); extern int vswscanf(const wchar_t , const wchar_t , __va_list); extern int vwscanf(const wchar_t , __va_list); extern float wcstof(const wchar_t , wchar_t *); #if defined(_LONGLONG_TYPE) extern long double wcstold(const wchar_t , wchar_t *); extern long long wcstoll(const wchar_t , wchar_t *, int); extern unsigned long long wcstoull(const wchar_t , wchar_t *, int); #endif / defined(_LONGLONG_TYPE) */ ...

Thank you very much plobsing... Your suggestion worked!! And almut has also given a very good explanation.	[reply]

Just FYI, the `_RESTRICT_KYWD` is a macro declared in `/usr/include/sys/feature_tests.h` on newer (v10) Solaris systems (`feature_tests.h` itself is included from `/usr/include/iso/stdio_iso.h`): `/* * The following macro defines a value for the ISO C99 restrict * keyword so that _RESTRICT_KYWD resolves to "restrict" if * an ISO C99 compiler is used and "" (null string) if any other * compiler is used. This allows for the use of single prototype * declarations regardless of compiler version. */ #if (defined(__STDC__) && defined(_STDC_C99)) #define _RESTRICT_KYWD restrict #else #define _RESTRICT_KYWD #endif` [download] However, as plobsing hinted at, you can probably get away without it. (This is a rather common source of various compilation problems, unfortunately.)	[reply] [d/l] [select]

Thank you almut... I got the mistake... As you mentioned, plobsing's solution worked.	[reply]
