[julia-users] complex int ? A gcc-ism?

[Victor Eijkhout]

My attempt to install Julia with the Intel compilers flounders on

make[2]: Entering directory `/work/00434/eijkhout/julia/julia-master/src'

CC usr/lib/libccalltest.so

/work/00434/eijkhout/julia/julia-master/src/ccalltest.c(295): error: 
_Complex can only be used with float, double, or long double types

  complex int r1;

  ^


/work/00434/eijkhout/julia/julia-master/src/ccalltest.c(296): error: 
_Complex can only be used with float, double, or long double types

  complex int r2;

  ^


>From all the googling that I've done, "complex int" is not legal C, but 
seems a gcc extension. True?


This looks like a test file, and the only place it ever occurs. Shall I 
just edit it out and call my installation completely?

[Victor Eijkhout]

I wish I could supply some general help. Here's the story as I understand 
it: the latest Intel compilers rely on gcc for full C++11 and higher 
support. That means you have to specify some tricky combination of Intel & 
gcc setup. On my system this was done by someone else, so I don't know the 
details. Here's the script that loads C++ support:

prepend_path("PATH","/opt/apps/gcc/4.9.1/bin")

prepend_path("LD_LIBRARY_PATH","/opt/apps/gcc/4.9.1/lib")

prepend_path("LD_LIBRARY_PATH","/opt/apps/gcc/4.9.1/lib64")


(that's lua, btw, but the meaning is obvious)


If you know what to ask me I'll be happy to dig further, but right now I 
can't explicitly tell you what Intel icpc uses from gcc to obtain C++1y 
functionality.

[Victor Eijkhout]

Ok, feel free to close this ticket. By putting enough gcc stuff in the path 
I managed to get it to install in the Intel compiler. At least I think it's 
doing that. The configure messages are still quite ambiguous.

[julia-users] Installing with Intel compiler

[Victor Eijkhout]

I'm trying to install in the the Intel15 compiler on Linux. In the Make.inc 
I've set ever ICC to true that I ccould find. The output is a complete mix 
of gcc and icc. Any suggestions for how to disabuse it of the notion that 
it's using gcc?
