Hi,

Thanks for hint. Why wasn't -lm needed when host machine was i386?
Anyway, now tcc builds with a warning, though:
tcc.c:9505:2: warning: #warning add arch specific rt_get_caller_pc()
Hope that is not critical.
But then libtcc1 fails:
arm-linux-gcc -O2 -Wall -c -o libtcc1.o libtcc1.c
libtcc1.c:140:2: #error unsupported CPU type
I am confused. Isn't libtcc1 needed for a cross compiler (host i386;
target arm) as well. Why does it fail for a native (arm, arm) compiler?
Building bcheck fails also. Why does it try to build that when it
doesn't in case of i386 host?
Haven't you checked the souce code libtcc1.c:
#if defined(__i386__)
#define sub_ddmmss(sh, sl, ah, al, bh, bl) \
... ...
#else
#error unsupported CPU type
#endif
You have to provide some arm assembly to replace the i386 ones ...
since you want to have a tcc targeted to arm cpu.
A fast way is to find these functions in gcc source code. I believe
that the libtcc1.c is also adapted from gcc, so you could find it
specially for arm cpu.
Hope you have the luck.
