Failed to build libgcc_eh.a is missing

by Clément Péron

Hi, I try to rebuild an old toolchain from my script which was originally using uClibc 0.9.33.X, i have updated to binutils 2.25, gcc 4.9.3 and uclibc-ng 1.0.5. But the build failed when building uclibc. Is something wrong with the configuration of gcc first stage ?

1.0.5 release

by Waldemar Brodkorb

Hi, the results of the OpenADK workshop in Essen are now included in the release. Fixes for gcc 5.2.x/x86 and mips64 for n32 are the most important ones. best regards Waldemar
