Hi Grischka,
Thank you for your reply.
First, I must say that tcc used to work ROOT on ARM (Rpi) for years just
using the default configuration. I don't understand quite well why tcc.h
suddenly needs to be changed.
Anyway, as gcc looks to use -DTCC_ARM_VFP:
gcc -o tcctest.gcc tcctest.c -DCONFIG_TRIPLET="\"arm-linux-gnueabihf\""
-DTCC_CPU_VERSION=7 -DTCC_TARGET_ARM -DTCC_ARM_EABI -DTCC_ARM_HARDFLOAT
-DTCC_ARM_VFP -fno-strict-aliasing -I.. -I..
As suggested, I added #define TCC_ARM_VFP around line 150 of tcc.h for
__arm__
This change alone no longer gives " ../arm-gen.c:27: error: #error
"Currently TinyCC only supports float computation with VFP instructions",
but, as still does Aarch64, gives:
----- libtest : tcc in threads -----
tcc: error: library 'c' not found
tcc: error: library 'c' not found
tcc: error: library 'c' not found
tcc: error: library 'c' not found

tcc: error: library 'c' not found
tcc: error: library 'c' not found

(2377 ms)
Adding $(NATIVE_DEFINES) does not help.
All other tests are OK.
Do you see the light?

Hi Christian,
there are two things basically you could do. First in tests/Makefile:78
you could try adding $(NATIVE_DEFINES):
@echo ------------ $@ ------------
./libtcc_tes$*$(EXESUF) $(TCCFLAGS) $(NATIVE_DEFINES) <-----
Second is at tcc.h:150, if you want to you could tweak the default
settings for these architectures. The bits there are meant basically
to make compiling tcc as simple as if it were a hello-world program
(which it is after all, or close to):
gcc tcc.c -o tcc
Therefor, if you think that your system configuration is somehow
"default", then you have my full okay to add the two or three lines
each there to get such simplicity as a feature. ;)
(Maybe TCC_ARM_VFP and/or CONFIG_TRIPLET and/or whatever you see
on the gcc command from make.) To see whether it really works you
would need to run two stages:
gcc tcc.c -o tcc && ./tcc -B. tcc.c -o tcc1
If you did install tcc previously, -B. may be omitted too.
As to 'usleep' and 'gettimeofday', maybe it needs unistd.h or time.h or
maybe sys/time.h. I see your gcc suggests to use 'fseek' instead of
'usleep'. That is interesting.
Thanks,
