On an armeabi-v7a device (phone) in the termux app with
clang & make installed this passes all the tests.
Can be used as a cross compiler to create "native apps" as well.
Example 'config-extra.mak' for the cross arm-eabi-tcc:
SYSROOT = <path_to_android_ndk...>/sysroot/usr
TRIPLET = arm-linux-androideabi
ANDRVER = 32
ROOT-arm-eabi = $(SYSROOT)
CRT-arm-eabi = {R}/lib/$(TRIPLET)/$(ANDRVER)
LIB-arm-eabi = {B};{R}/lib/$(TRIPLET)/$(ANDRVER);{R}/lib/$(TRIPLET)
INC-arm-eabi = {B}/lib/include;{R}/include/$(TRIPLET);{R}/include
DEF-arm-eabi = -DTCC_TARGET_ARM -DTCC_ARM_VFP -DTCC_ARM_EABI
DEF-arm-eabi += -DTARGETOS_ANDROID -DCONFIG_TCC_PIE -DCONFIG_NEW_DTAGS
DEF-arm-eabi += -DCONFIG_TCC_ELFINTERP=\"/system/bin/linker\"
# on unix replace ';' by ':'.
$ ./configure && make cross-arm-eabi && make install

/* tccdefs.h

|
|
Nothing is defined before this file except target machine, target os
|
|
and the few things related to option settings in tccpp.c:tcc_predefs().
|
|
|
|
This file is either included at runtime as is, or converted and
|
|
included as C-strings at compile-time (depending on CONFIG_TCC_PREDEFS).
|
|
|
|
Note that line indent matters:
|
|
|
|
- in lines starting at column 1, platform macros are replaced by
|
|
corresponding TCC target compile-time macros. See conftest.c for
|
|
the list of platform macros supported in lines starting at column 1.
|
|
|
|
- only lines indented >= 4 are actually included into the executable,
|
|
check tccdefs_.h.
