So what should I do during configure script?
You should not use "--cpu=...". This would build a tcc
which thinks that it's on riscv, while it's running on arm.
For example. arm64-tcc knows __uint128_t, but riscv64-tcc does
not. (See include/tccdefs.h)
Anyway. Type 'make help' and read:
To build tcc and all cross compilers:
./configure --enable-cross
make
make test
sudo make install
To build only the riscv64 cross compiler:
./configure
make cross-riscv64
sudo make install
To check its paths:
riscv64-tcc -vv
tcc version 0.9.28rc (riscv64 Linux)
install: /usr/local/lib/tcc
include:
/usr/local/lib/tcc/include
/usr/riscv64-linux-gnu/include
libraries:
/usr/local/lib/tcc
/usr/riscv64-linux-gnu/lib
libtcc1:
/usr/local/lib/tcc/riscv64-libtcc1.a
crt:
/usr/riscv64-linux-gnu/lib
elfinterp:
/lib/ld-linux-riscv64-lp64d.so.1
As you can see, this riscv64-tcc in order to work wants
includes, libs, crtx.o for riscv64 in /usr/riscv64-linux-gnu/...
You can install them on debian systems for example with:
apt install libc6-dev-riscv64-cross
You can also copy those files from the target system instead.
You can also make riscv64-tcc look in other places.
See 'make help' about 'config-extra.mak'
