[Insight-users] Re: error msg got when installing ITK on IBM AIX 5.2 (Henry)

[Luis Ibanez]

Hi Henry,

Looking at the source code of CMake,

         /CMake/Utilities/cmcurl/strerror.c

in line 45 where you report the error, we find that there is
code specific for AIX:

#if defined(HAVE_STRERROR_R) && defined(HAVE_NO_STRERROR_R_DECL)
#ifdef HAVE_POSIX_STRERROR_R
/* seen on AIX 5100-02 gcc 2.9 */
extern int strerror_r(int errnum, char *strerrbuf, size_t buflen);
#else
extern char *strerror_r(int errnum, char *buf, size_t buflen);
#endif
#endif



Therefore, we are going to need your help to figure out what the
right code should be here for AIX and gcc 3.4, in your installation.


It seems that the function prototypes in

          /CMake/Utilities/cmcurl/curl/curl.h

are not matching the actual implementations in

         /CMake/Utilities/cmcurl/

In particular, the functions:

          curl_easy_strerror()
          curl_multi_strerror()

It is likely that many of the compile-time discovery
actions that CMake performs during configuration are
not returning the appropriate settings for your
platform (AIX+Gcc3.4).


You may want to start by posting a detailed description
of your CMake build to the CMake users list. They will
be better informed on how to find the right configuration
settings for your platform.

Once you get CMake to build in your platform, it should
be trivial to get ITK to build.


    Regards,


       Luis
