Hi,

I am using the latest SDK for TRB140 to compile a Firmware with glibc support, instead of musl. The make process always crashes with the error log attached below. Any suggestions how to solve the issue?

checking installed Linux kernel header files... 3.2.0 or later

checking for kernel header at least 4.14.0... too old!

configure: error: *** The available kernel headers are older than the requested

*** compatible kernel version

make[3]: *** [Makefile:31: /home/lauda/Documents/Original_libc/rutos-mdm9x07-trb1-gpl/build_dir/toolchain-arm_cortex-a7+neon-vfpv4_gcc-8.4.0_glibc_eabi/glibc-2.33-headers/.configured] Error 1

make[3]: Leaving directory '/home/lauda/Documents/Original_libc/rutos-mdm9x07-trb1-gpl/toolchain/glibc/headers'

Hint: I followed the all instructions as described in the README.

Hello,

Does it fail only when using glibc, or compiling sdk without any changes or other changes succeeds?

 toolchain/glibc/common.mk:

PKG_NAME:=glibc

PKG_VERSION:=2.27

PKG_SOURCE_PROTO:=git

target/linux/mdm9x07/Makefile:

Interesting.

What are the values of PKG_SOURCE_VERSION and PKG_MIRROR_HASH in toolchain/glibc/common.mk ?
by anonymous

PKG_SOURCE_SUBDIR:=$(PKG_NAME)-$(PKG_VERSION)

PKG_SOURCE_VERSION:=daf88b1dd1a41fcb324801c02ead7a8d5aac3851

PKG_MIRROR_HASH:=fc78ef46c52c922ea44d079533d4d3017a0c921b4ed9aab8bb1dd071322b169f

PKG_SOURCE_URL:=https://sourceware.org/git/glibc.git

PKG_SOURCE:=$(PKG_NAME)-$(PKG_VERSION)-$(PKG_SOURCE_VERSION).tar.xz

Maybe there is a path to success here. With this 2.27 version the first checks pass, but the process still fails during the "apply patches" phase. Could you execute tar cvfz glibcpatches.tar.gz toolchain/glibc/patches in this special SDK base folder and send me the file via PM ?

It is possible to get rid of the kernel 4.14 requirement while keeping the 2.33 version of glibc by editing toolchain/glibc/common.mk. glibc itself and most of the base openwrt packages will compile without hiccups. The few ones that don't will require some work.

Unfortunately the SDK contains several packages from Teltonika only available in executable / shared object / object file format which directly reference musl on some form or another. Those packages cannot be ported without access to the source code.

So the hypothetical "path to success" turns out to be a dead end.
