Hello, I am using gcc version 3.4.3 (csl-sol210-3_4-branch+sol_rpath) to compile gcc-4.0.2 on a Sunfire V40z AND64 4-processor Solaris 10 box. I create a directory in /tmp and use the following two commands. /export/home/carlo/src/gcc-4.0.0/configure --prefix=/export/home/carlo/local40 --enable-bootstrap gmake bootstrap No matter which version of gcc-4.0.x I use it always stops with the following error: /tmp/comp-40/gcc/xgcc -B/tmp/comp-40/gcc/ -B/export/home/carlo/local40/i386-pc-solaris2.10/bin/ -B/export/home/carlo/local40/i386-pc-solaris2.10/lib/ -isystem /export/home/carlo/local40/i386-pc-solaris2.10/include -isystem /export/home/carlo/local40/i386-pc-solaris2.10/sys-include -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -I. -I. -I/export/home/carlo/src/gcc-4.0.0/gcc -I/export/home/carlo/src/gcc-4.0.0/gcc/. -I/export/home/carlo/src/gcc-4.0.0/gcc/../include -I./../intl -I/export/home/carlo/src/gcc-4.0.0/gcc/../libcpp/include -g0 -finhibit-size-directive -fno-inline-functions -fno-exceptions -fno-zero-initialized-in-bss -fno-unit-at-a-time -fPIC \ -c /export/home/carlo/src/gcc-4.0.0/gcc/crtstuff.c -DCRT_BEGIN \ -o crtbegin.o Assembler: crtstuff.c "/var/tmp//ccgxmMNg.s", line 34 : Illegal mnemonic "/var/tmp//ccgxmMNg.s", line 34 : Syntax error "/var/tmp//ccgxmMNg.s", line 48 : Illegal mnemonic "/var/tmp//ccgxmMNg.s", line 48 : Syntax error "/var/tmp//ccgxmMNg.s", line 79 : Illegal mnemonic "/var/tmp//ccgxmMNg.s", line 79 : Syntax error gmake[2]: *** [crtbegin.o] Error 1 gmake[2]: Leaving directory `/tmp/comp-40/stage1-gcc' gmake[1]: *** [all-stage1-gcc] Error 2 gmake[1]: Leaving directory `/tmp/comp-40' gmake: *** [stage1-bubble] Error 2 netview% I downloaded gcc-3.4.4 and it compiled. I checked configure options and don't see anything obvious. Am I missing something? Is gcc-4.0.x to new to work on Solaris 10 X86 yet? Thanks. Carlo
