From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; T312461) Description of problem: If I'm right, the include file /usr/include/bits/byteswap.h (line 84-86, 45-47) in glibc-devel-2.2.93-5 for RedHat 8.0 have some bugs: 1. #define __bswap_16(x) should be #define __bswap_32(x), otherwise if __GNUC__ is not defined, i.e, people use compiler other than gcc, __bswap32(x) will not be defined! 2. After change __bswap_16 to __bswap_32, the macro define should change to "# define __bswap_32(x) __bswap_constant_32 (x)". The __extension__ is a GNU extension, right? At least, intel compiler (icc) doesn't support it. The same for the definition of macro __bswap_16 (line 45-47). To make sure this is not a redhat bug, I download http://ftp.gnu.org/gnu/glibc/glibc-2.3.1.tar.gz, and found the same bug in sysdeps/i386/bits/byteswap.h Is that right? Thanks! Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: Just try to compile a program which use htonl ... with non-GCC compilers, such as icc, ... Actual Results: It won't pass the compile, as I've said in the description Additional info:
I think I have a similar problem. I'm using an Intel compiler to compile a program which worked just fine under Redhat 7.3. Now when I compile I get the following error: ifc -O3 -tpp7 -Vaxlib -w95 -cm -static -r8 -o prism_static x86_prism4-0e_gui.o -L/usr/lib -L./library/x86 -L../f90/library/x86 -lprism ./library/x86/libprism.a(create_socket.o): In function `create_socket_': create_socket.o(.text+0x40): undefined reference to `__bswap_32' make: *** [prism_static] Error 1
Should be fixed in glibc-2.3.1-9 and later.
