Migrating From ECO 5.0 to ECO 6.0 for STM32MP15A custom board. TF_A, TF_FWCONFIG, U-BOOT and KERNEL all builds fine but stuck at building OPTEE..
Not using Yocto but the source tarballs provided in the developer package.
OPTEE builds fine on ECO 5.0 (just built it right now with ECO SDK 5.0)
OPTEE build fails on ECO 6.0 (SDK 6.0)
All on the same machine.
Same Cube-MX generated files and build commands used for both ECO versions.

arm-ostl-linux-gnueabi-ld.bfd: cannot find libgcc.a: No such file or directoryon ST's China OPTEE WIKI it says:
https://wiki.stmicroelectronics.cn/stm32mpu/index.php?title=How_to_configure_OP-TEE&oldid=78220
To overcome the issue, add the directive LIBGCC_LOCATE_CFLAGS=--sysroot=$SDKTARGETSYSROOT. But that did not work, for exampel the Wiki given command fails as well
make PLATFORM=stm32mp1 CFG_EMBED_DTB_SOURCE_FILE=stm32mp157c-ev1.dts CFG_TEE_CORE_LOG_LEVEL=2 LIBGCC_LOCATE_CFLAGS=--sysroot=${SDKTARGETSYSROOT} O=out allOn another China web wiki it says
https://wiki.st.com/stm32mpu/wiki/How_to_build_OP-TEE_components
To overcome the issue, add the directive CFLAGS32=--sysroot=$SDKTARGETSYSROOT or CFLAGS64=--sysroot=$SDKTARGETSYSROOT, depending on target architecture. For example: WHICH ACTUALLY WORKED !!
it seems a known issue discussed by experts on github back in 2021, but the patch provided by the link is gone.

But the patch is still needed for internal OE-built toolchain to pass
sysroot, otherwise libgcc.a cannot be found:
| aarch64-oe-linux-ld.bfd: cannot find libgcc.a: No such file or directory
...
+Explicitly pass the new variable LIBGCC_LOCATE_CFLAGS variable when searching
+for the compiler libraries as there's no easy way to reliably pass --sysroot
+otherwise.Same issue report on TI forum.
Any guidance how to fix this ?
As with all cases and mine , it fails at:
ldelf/ldelf.elf
P..S Ubuntu 24.10 (if an answers like "not supported distro": 5.0 builds but the NEWER tool chain does not)
A solution mentioned is this but no idea how to apply or if it should fix it:
Allow setting sysroot for libgcc lookup.Explicitly pass the new variable LIBGCC_LOCATE_CFLAGS variable when searching for the compiler libraries as there's no easy way to reliably pass --sysroot otherwise.

A patch was released here:
UPDATE ! This issue could be reproduced with the OPTEE Makefile.sdk. Go into the optee folder. then
make -f $PWD/../Makefile.sdk cleanthen start male in the optee folder:
make -f $PWD/../Makefile.sdk allwhen running this command the build goes fine.
Refer to the output at beginning of the make command and copy the string , in my case:

arm-ostl-linux-gnueabi-ld.bfd: cannot find libgcc.a: No such file or directoryAccording to the wiki the command and options are all correct to build from the command prompt, but there is something that makes the Makefile.sdk do something more, but what ....?
libgcc.a files do exists in the ECO 6.0 SDK
