Summary: Buildroot fails to account for "nof" subdirectory (no
floating point)
Product: buildroot
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
AssignedTo: unassigned at buildroot.uclibc.org
ReportedBy: gnemesure at avtec.com
CC: buildroot at uclibc.org
Estimated Hours: 0.0
I am using buildroot-2010.2 to target a 440GP processor with no hardware
floating point.
When software floating point is enabled (BR2_SOFT_FLOAT), the gcc build puts
libgcc_s.so, libstdc++.so, etc. in an "nof" subdirectory that buildroot is not
accommodating. These are deposited in
$(STAGING_DIR)/usr/powerpc-linux-uclibc/lib/nof
but the toolchain/gcc/gcc-uclibc-4.x.mk makefile tries to copy these files from
$(STAGING_DIR)/usr/powerpc-linux-uclibc/lib
which results in failure to copy the libraries to the target filesystem.
This is with GCC 4.3.4. I'm not sure if this applies to other versions as well.
As a workaround, I think I can enable floating point in the kernel, and then
enable hardware floating point in the toolchain.
