Dear Sir,
First, thank you for your efforts.
I am a system administrator of Sun Blade 1000 (Ultra-III) which I have installed the gcc-3.0.2
According to man command, the gcc have following option for sparc machine.
SPARC Option
-mcpu=cpu-type -mtune=cpu-type -mcmodel=code-model -m32
-m64 -mapp-regs -mbroken-saverestore -mcypress
-mepilogue -mfaster-structs -mflat -mfpu -mhard-float
-mhard-quad-float -mimpure-text -mlive-g0 -mno-app-
regs -mno-epilogue -mno-faster-structs -mno-flat
-mno-fpu -mno-impure-text -mno-stack-bias -mno-
unaligned-doubles -msoft-float -msoft-quad-float
-msparclite -mstack-bias -msupersparc -munaligned-
doubles -mv8
I hope to compile my c-code with 64-bit option.
Can gcc-3.0.2 support the 64-bit compiling under Sun Solaris-8 (Ultra Sparc-III machine) ?
Though I have installed gcc-3.0.2, I can not use -m64 option in my computer.
Following error is generated when I use -m64 option.
gcc -m64 -o sample sample.c -lm
cc1: -m64 is not supported by this configuration
Please, would tell me the way how I can use -m64 option to compile my code with 64-bit ?
May I reinstall the gcc-3.0.2 with other configure option to use -m64 option in my machine ?
Thank you for your kindness in advance.
Sincerely yours,
Yujong Kim
