Thanks for the reply. I will try that if you think what I'm about to say does not jive or you know what the answer to it is... Some of the project code I'm porting from gcc2.95.2 to gcc323 involves compiling my project code with ACE5.2(which was compiled under 2952 as well). Well, I was getting similar "long not supported by ISO" warnings from ACE headers files when compiling my project code with ACE5.2 and gcc323. So I installed ACE5.3.6 (and compiled it under gcc3.2.3) and then when I compiled my project code with ACE 5.3.6 and gcc323 the long not supported errors went away. So I was guessing that ACE5.3.6 somehow set compiler directives that cleared up the long not supported warnings and maybe that's all I have to do myself. What do you think? If I must recompile gcc323 with -m64, If I use -mtune=ultrasparc option instead (as noted in the install readme below) would that do the trick since my platforms are all ultrasparcs ? http://gcc.gnu.org/install/specific.html#sparc-sun-solaris2* Starting with Solaris 7, the operating system is capable of executing 64-bit SPARC V9 binaries. GCC 3.1 and later properly supports this; the -m64 option enables 64-bit code generation. However, if all you want is code tuned for the UltraSPARC CPU, you should try the -mtune=ultrasparc option instead, which produces code that, unlike full 64-bit code, can still run on non-UltraSPARC machines Much thanks for the help :) Phil -----Original Message----- From: lrtaylor@xxxxxxxxxx [mailto:lrtaylor@xxxxxxxxxx] Sent: Wednesday, February 11, 2004 6:18 PM To: Crescioli, Phil Subject: RE: #error "Both _ILP32 and _LP64 are defined" I believe that GCC builds 32-bit executables by default. If this is an option, you could try telling it to build a 64-bit binary instead using the -m64 option.

I wish I could set a compiler directive to solve it. My attempts so far don't work. Any help is appreciated. I'm on a sparc system running solaris 8 with gcc 3.2.3. My code below finds its PID from the proc tables in /usr/proc/* and then finds it's file name using fstream and procfs structure variables then prints the executed filename to stdout. ============================================================ #include <iostream> #include <fstream> #include <procfs.h> #include <unistd.h> using namespace std ; int main(void) { char *buffer ; ifstream procFile ; char procFileName[25] ; psinfo_t info ; int pid_ ; int length ; cout << "Entering Main()" << endl ; // Get this processes Process IDentification (PID) pid_ = getpid(); sprintf(procFileName, "/proc/%d/psinfo", pid_); procFile.open(procFileName, ios::binary) ; if (procFile.is_open()) { // get length of file: procFile.seekg(0, ios::end); length = procFile.tellg(); procFile.seekg(0, ios::beg); // allocate memory: buffer = new char [length]; // read data as a block: procFile.read(buffer,length); procFile.close(); strcpy(buffer, info.pr_fname); cout << "buffer =" << buffer << endl ; } else{ cout << "cant open process info file" << endl ; } cout << "Exiting Main()" << endl ; return (0); } /* main */ ====================================================================== When I compile this code with the cmd below I get the following error ====================================================================== g++ -ansi -g -Wall -o ProcInfoTest ProcInfoTest.cpp In file included from /usr/include/sys/procfs.h:41, from /usr/include/procfs.h:26, from glxProcInfoTest.cpp:3: /usr/include/sys/procfs_isa.h:230: 'uint64_t' is used as a type, but is not defined as a type.
