Hello All,
I have installed the last stable scratchbox on Debian system. It can build
BusyBox 1.1.1.
However, When I use it to build MPlayer-1.0pre7, It fails in the link
process. It seems that the uclibc does not include
sinf cosf functions. I have perofmred a test.c:
#include <math.h>
#include <stdlib.h>
int main()
{
float f = 3.14;
f = sinf(f);
printf("Start %s f=%f\n", __FUNCTION__, f);
return 0;
}
gcc test1.c -lm
/var/tmp/ccA383gk.o(.text+0x1c): In function `main':
test1.c: undefined reference to `sinf'
collect2: ld returned 1 exit status
It seems that the
scratchbox-toolchain-arm-gcc3.4-uclibc0.9.27_1.0.3_i386.deb does not
contians the sinf cosf function,
How to resolve this problem? I have to make a toolchain by myself?
Thank you!
Tyler Li
