Hi,
I have problems with the package ti-gfx.
Setup uses a buildroot compiler with eabihf enabled.
All goes fine until TI's pvrsrvctl gets called:
#pvrsrvctl
/usr/bin/pvrsrvctl: line 1: syntax error: unexpected word (expecting ")")
# strace pvrsrvctl
execve("/usr/bin/pvrsrvctl", ["pvrsrvctl"], [/* 16 vars */]) = -1 ENOEXEC (Exec format error)
write(2, "strace: exec: Exec format error\n", 32strace: exec: Exec format error
) = 32
exit_group(1) = ?
+++ exited with 1 +++
But no problems with the modules
# lsmod
Module Size Used by Not tainted
bufferclass_ti 4734 0
omaplfb 10298 0
pvrsrvkm 157244 2 bufferclass_ti,omaplfb
First I thought it is ABI-problem so I configured the system until they match,
see below, but this didn't help.
Could it be a mis-match in the eglibc version?
# LD_TRACE_LOADED_OBJECTS=1 /usr/bin/pvrsrvctl
libc.so.6 => /lib/libc.so.6 (0x401dc000)
/lib/ld-linux-armhf.so.3 (0x40094000)
Many thanks for any hints!
Peter

Dear Peter Kuemmel,

Interesting. Were you building the kernel with Buildroot, or separately?
If you built your kernel with Buildroot, then maybe we should add
something like:
$(if $(BR2_ARM_INSTRUCTIONS_THUMB)$(BR2_ARM_INSTRUCTIONS_THUMB2),
$(call KCONFIG_ENABLE_OPT,CONFIG_ARM_THUMB,$(@D)/.config))
This way we would ensure that the kernel gets built with
CONFIG_ARM_THUMB=y when the Thumb or Thumb-2 instruction sets have been
selected for userspace.
Thoughts?
Thomas

This is a good idea, but wouldn't help with Peter's problem: the
pvrsrvctl binary is not built by buildroot, so the problem occurs even if
buildroot is build with ARM instructions.

Yes, pvrsrvctl is not build by buildroot, but this is not the problem.
pvrsrvctl needs a kernel which supports thumb, so enabling thumb in the
kernel automatically by buildroot would solve the problem. (And would have
saved me many hours).

Yes, but Thomas proposed to add it automatically only when you select to
build everything with thumb. It would not be done in the default case of
BR2_ARM_INSTRUCTIONS_ARM_CHOICE (which you probably have...).
