Hi Folks, I need 64-bit code on Sun Solaris 2.9. The specification of the system (gpc -v): Reading specs from /usr/local/lib/gcc-lib/sparc-sun-solaris2.9/3.2.1/specs Configured with: /users/cserzo/big/src/gcc-3.2.1/configure --enable-languages=pascal --disable-nls --with-gnu-as --with-gnu-ld --with-as=/usr/local/bin/as --with-ld=/usr/local/bin/ld Thread model: posix gpc version 20030507, based on gcc-3.2.1 Apparently, the 32-bit compiler should be able to generate 64-bit code. The problem is the missing 64-bit libgpc. The 64-bit version of the gcc library is there but its gpc counterpart not. How could I force the compilation of this library at build time? I made another test. With the 32-bit version one should be able to address ~ 4.3 Gb of the memory. In practice, I can allocate about 2Gb (array[1..500000000] of integer) but not much more. If I compile a code containing array[1..600000000] of integer the following error generated: /var/tmp//ccrvtgAm.s: Assembler messages: /var/tmp//ccrvtgAm.s:7: Error: .COMMon length (-1894967300.) <0! Ignored. /var/tmp//ccrvtgAm.s:7: Warning: rest of line ignored; first ignored character is `,' What is the correct way to make use of the memory in this case? Cheers, miklos
