Binaries in hardfp/opt/vc/lib do not have hard-float flag in elf header #436

Closed rogerjames99 closed 9 years ago

The binaries in the hardfp/opt/vc/lib directory do not have the hard-float flag set in the ELF header. This means that later versions of the ld.so loader will not find them via the ldconfig cache even though they appear to be in there. This may also apply to other parts of the hardfp tree, but I have not checked. Can someone with access check in a rebuild with the correct flags set.

Can you explain exactly how you are detecting this and what you think should be done differently to fix this? The libraries are built with -mcpu=arm1176jzf-s -mfpu=vfp -mfloat-abi=hard so you'll have to be more specific about what is being requested.

Mea culpa,

I just rechecked and realised I had used the files from the wrong part of the tree. Please kill this issue.

The adafruit pitft install kills the /opt/vc part of the tree and I had used the wrong files to replace it. Loads of strange missing so file errors! Took a while to twig as the ldconfig cache looked like the files where present. Maybe I should suggest to the loader guys that they put out a warning if a file is ignored due to wrong flags.

Sorry,

Roger
