I compile for arm7tdmi.
that was the environnment.make.

Sorry for this error. Thanks for any help !
I suggest to use an arm-elf or arm-eabi toolchain not a arm-linux toolchain. You can get precompiled binaries for Linux (if this is your OS) i.e. from gnuarm.org and codesourcery.com I don't know enough about the arm-linux targets but but with such a toolchain you may try the compiler-options: -msoft-float or -mfloat-abi=soft (add to CFLAGS).

I'm in training course and I have to use the arm-linux targets with such a toolchain. So I tried the compiler-option: -msoft-float or -mfloat-abi=soft (add to CFLAGS) but I have exactly the same errors ! Someone can help me please ?? Have a nice day !
