I tried to use crosstool-ng to generate a toolchain for Linux on big
|
|
endian arm with recent versions of gcc, glibc, etc... but had a few
|
|
problems.
|
|
|
|
It appears that the gcc patch (for gcc 4.2.x)
|
|
for big-endian arm (240-arm-bigendian.patch) lacks the change attached
|
|
to this mail as 240-arm-bigendian2.patch.
