[Tinycc-devel] Several Question about arm-tcc

[Bin Shi]

Hello, I am trying to compile tcc on a little endian armv4 host simulated by QEMU, the detailed info about this machine could be get from http://people.debian.org/~aurel32/qemu/arm/

And I have 2 questions about it:

1. I can compile tcc with gcc, but failed with tcc it self (--cc=/tcc/bin/tcc), how to fix it?

    the error message is listed as follow:

debian-arm:~/tinycc# ./configure --prefix=/tcc --exec-prefix=/tcc --cpu=armv4l --cc=/tcc/bin/tcc

2. I notice that the macro TCC_ARM_VFP is defined, but TCC_ARM_EABI is not,

    what is the difference between arm-vfp-gcc and arm-eabi-tcc ? What to do if I want arm-eabi-tcc ?
