In this case, reality and the map differs. NWFPE toolchains built by cross-tool, buildroot, and www.gnuarm.com not sure abnout the last) all bombs when they reach the "-msoft-float" > >> If you happen to use a compiler which does not support soft-float, >> I.E: uses NWFPE, then the build will fail. > > Even if it's configured for NWFPE as default setting, it should still > be able to generate soft-float. It doesn't. If you think so, show me an ARM toolset which behaves in this way. > And in the end, it should make no differece at all as we don't use FP > in U-Boot. > Without "-msoft-float", both the softfloat and NWFPE toolchains will complete the build since floating point is not used.. With "-msoft-float", NWFPE based toolchains for ARM appears to abort. If it doesn't make any difference, and U-Boot does not use floating point then it make sense to remove all "-msoft-float" for ARM Makefiles.' It is so easy to replace all fixed parameters with symbolic Makefile variable which can be modified by your make command $ make "MYPARS=-msoft-float" uboot With sensible defaults which can be overriddern, this would solve the problem, without having to locally *patch* the source. When you are building several u-boots for different ARM chips from the same source you really do not want to patch the source. > > Best regards, > > Wolfgang Denk > Best Regards Ulf Samuelsson [EMAIL PROTECTED] Atmel Nordic AB Mail: Box 2033, 174 02 Sundbyberg, Sweden Visit: Kavallerivägen 24, 174 58 Sundbyberg, Sweden Phone +46 (8) 441 54 22 Fax +46 (8) 441 54 29 GSM +46 (706) 22 44 57 ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
