Message-ID: <49256AE8.002C32D5.00@notes.topcon.co.jp> How do you do. I am an engineer in Japan. Now, I am worried of that how to installing GCC cross-compiler for ARM. I have failed in all though constructed many times. Please help me. The environment is as follows. Cygwin : 1.3.2 GCC : gcc-core-3.0.1 gcc-g++-3.0.1 BINUTILS : binutils-2.11.2 NEWLIB : newlib-1.9.0 HOST : Windows98 machine (i586-pc-cygwin) TARGET : ARM7 for embedded And, the construction method is as follows. STEP1 Configure & Install the GNU binary utilities. 1 ./configure --prefix=/tools \ --target=arm-elf 2 make cross 3 make install STEP2 1 cd /src/gcc-3.0.1 2 ln -s /src/newlib-1.9.0/newlib 3 ln -s /src/newlib-1.9.0/libgloss STEP3 Configure & Install the GCC. 1 ./configure --prefix=/tools --target=arm-elf \ --enable-languages=c,c++ \ --enable-multilib \ --with-gnu-as \ --with-gnu-ld \ --with-include-headers=/src/newlib-1.9.0/newlib/libc/include \ --with-gnu-newlib 2 make cross 3 make install STEP4 Configure & Install the newlib. 1 ./configure --prefix=/tools \ --target=arm-elf 2 make 3 make install The following errors occurred when the my program was compiled by the GCC compiler which constructed with these steps. startup.o: undefined reference to `_SS_SoftwareInterrupt' startup.o: undefined reference to `_SS_AbortPrefetch' startup.o: undefined reference to `_SS_AbortData' startup.o: undefined reference to `_SS_Reserved' startup.o: undefined reference to `_SS_Irq' startup.o: In function `_jump_to_main': startup.o: undefined reference to `_main' main.o: In function `main': Perhaps, I think that the made compiler is not for embedded. Because, the function of which these errors go out is an exception handling.(interrupt function) To tell the truth, I have the compiler which does not support thumb. The error does not go out when only the execution file(c, c++) is replaced. Moreover, when the execution files are compared, the execution file which I constructed is smaller. (ex.) constructed had arm-elf-c++ 213k 579k arm-elf-gcc 210k 575k I do not understand the option when the configuration is done. Please teach it. ------ Want more information?
