I'm compiling the following program using GCC-3.2.3 configured as a cross-compiler targeting "sparc-linux" and hosted on ix86-linux. int main (void) { int i; i = i / 3; return 0; } My target system uses a sparc-v7 compliant processor without integet multiplication and division instructions, so I'm compiling with: sparc-linux-gcc -mcpu=v7 -fno-builtin -c tst.c -o tst.o but when I try to link the generated object, like this: sparc-linux-ld tst.o /path/to/gcc-lib/3.2.3/libgcc.a -o tst I get an error about the linker not been able to find the ".div" function. I was under the impression that the integer-math functions called by code generated from C integer expressions were implemented in "libgcc.a". Obviously they are not! Looking arround I found a ".div" function in *libc*, but for several reasons, I don't want to link my program with the glibc "monster". All I want is a library that supports the *compiler generated* function references. Isn't "libgcc" supposed to be exactly that??? I finaly managed to get my program (performing integer math) link, using this round-about way: mkdir libintm; cd libintm ar x /path/to/glibc/libc.a \ addmul_1.o sub_n.o submul_1.o dotmul.o \ mul.o mul_1.o mul_n.o umul.o \ div.o udiv.o udiv_qrnnd.o sdiv.o ldiv.o lldiv.o \ divmod_1.o divrem.o rem.o urem.o ar cr libintm.a *.o ranlib libintm.a and then link my program with "-lintm". Are the above-mentioned functions *exactly* the ones required? That is, does the compiler implicitly produce refences *only* to these functions, and to *all* of these? Is there a nicer way to achieve the same result? /npat P.S. Obviously my intention is to compile a program that will run at "boot"-time without the services of an operation system, or of an extensive standard library. -- Don't ever think you know what's right for the other person.
