Problem with #include <climits>

[mnaydin]

Hi,

I hava problems compiling C++ programs which includes climits. The operating system is Debian Linux (64-bit), icc version is 12.0.4, gcc version is 4.3.2. The following test program does not compile with icpc (but it compiles with g++):

#include
#include
int main()
{
std::cout << INT_MAX << "\\n";
return 0;
}

The error message:
/usr/include/limits.h(125): catastrophic error: cannot open source file "limits.h"
# include_next
^

compilation aborted for test.cpp (code 4)

Interestingly, when I use #include , instead of #include , the test program compiles with icpc and runs correctly.

Hi,

i have compile your sample with icpc 12.0.4.20110427 version under openSUSE 12.1 M1 64 Bit linux
without any problems, i think its a OS or environment setting problem,
on openSUSE 12.1 the Intel ICC/ICPC Version 12.0.4.20110427 works without troubles with your sample

I can also compiler the code in FC11 using icc 12.0.4.191. Could you please try compiling with gcc?

Hi,

same problem here: Ubuntu 10.04,g++ (Ubuntu 4.4.3-4ubuntu5) 4.4.3, icpc12.0.4 20110427

Compiling the small sample program with icpc gives the same error message. Compiling it with g++ works fine.

When I compile the sample with

icpc -Wall -I /opt/intel/composerxe/include

it works but on my real program I get then the warnings

/opt/intel/composerxe/include/math.h(19): warning #561: nonstandard preprocessing directive

# include_next /* utilize and expand sys header */

/opt/intel/composerxe/include/math.h(19): warning #561: nonstandard preprocessing directive # include_next /* utilize and expand sys header */

Any ideas?

Cheers

Patrick

Hi again,

it seems the problem is the compilervars_arch.sh script. When you look at the other scripts which were made for

tbb, ipp, mkl than you see that they set the CPATH to the corresponding include directory. The include path of the

compiler is not set. When I add

if [ -z "${CPATH}" ]; then

CPATH="${INSTALL_DIR}/compiler/include"; export CPATH

else

CPATH="${INSTALL_DIR}/compiler/include:$CPATH"; export CPATH

fi

if [ -z "${CPATH}" ]; then CPATH="${INSTALL_DIR}/compiler/include"; export CPATHelse CPATH="${INSTALL_DIR}/compiler/include:$CPATH"; export CPATH

fi

to the

/opt/intel/composerxe-2011.4.191/pkg_bin/compilervars_arch.sh

script it seems everything is running fine.

Cheers

Patrick
