GDAL 1.2.5 fails to compile on SGI IRIX 6.5.25 using MIPSpro Compilers 7.4.3

[pakulas@…]

The function "atoll" with is supposedly declared inside stdlib.h is not found 
by the CC compiler (c++) inside the file called /gdal-1.2.5/port/cpl_conv.cpp.  
However the configure script finds the “atoll” support and hence an error 
results from the compilation.

A simple workaround is to modify the following inside /gdal-
1.2.5/port/cpl_config.h:

#define HAVE_ATOLL 1
#undef HAVE_ATOLL

Once this is added the issue is resolved, and the library is correctly built.  
However it uses the 32bit “atol” function, which is not desirable.

I created a stand alone program utilizing "atoll" on the same platform and 
compiles with CC only if you use "using namespace std" instead of #include 
<stlib.h>.  

I hope this information would be useful in solving this problem.

Scott,

I could move the check for atoll to be done in a C++ environment in the 
configure script; however, I would expect this to disable the use of
atoll on IRIX.  

I am very hesitant to do the "using namespace std" thing without having
a decent grasp of the problems it is likely to cause on other system or
with other compilers.  Espcially if it involves not including stdlib.h. 

If made the change to test for atoll in the C++ environment in the configure
script, would you be willing to test that things build cleanly on your system?
It still wouldn't be 64bit safe, of course, but at least it would build easily.
It would be up to you to hack in an appropriate local fix if you need proper
64 bit support.

An experiment was done moving the configure test into the C++ environment, and it didn't help.

Not most common problem nowadays, perhaps could be closed?

Closing. We do not really "support" SGI IRIX
