imx-codec package bug (missing hardfp libraries)

sfinx — Sun, 17 Jul 2016 04:02:34 GMT

Hello,

There is an error in imx-codec package distribution (all versions including latest 4.0.9) for IMX CPU's. The packages has the install option for CPU's with FPU (--enable-fhw configure option). But it contains only test binaries for hard FPU option and missed the corresponding fhw libraries. The package include libraries only with Soft FPU emulation. This leads to constant errors while running any tests in Yocto/Debian for IMX6 CPU:

....

and inability of linking any tests using gcc-linaro-4.9-2015.05-x86_64_arm-linux-gnueabihf compiler. Please fix the package by adding missing hard-fp libraries.

TIA, Rus

Update1: Yocto can run soft-floating tests, but Debian still not.

Update2: Debian can run softfp tests after upgrading to libc-2.21

Update3: The package has another missing file g729_common_api.h

Hi First

i.MX6Q does not have fpu as described in Table 12-4. Cortex-A9 Core configuration

i.MX6DQ Reference Manual

Hi,

I did not mentioned the imx6q at all. The bug is related to library not the CPU. I'm, using DART-6UL with Ultralight IMX6, it has the FPU.

As I can see the mixed EABI can't be loaded by ld.so prior to libc 2.21 which affect at least the Debian distro. The main concern is that hardfp libraries are usually faster than softftp.

And last - seems like nobody tried to make compile test using this package (mainly because of messy build system) - there are missing header files.
